A global platform which is within approximately 50 milliseconds of about 95% of the Internet connected population, serving on average, over 46 million HTTP requests per second. About the Team Delivering this platform with high performance and efficiency depends on advanced Linux kernel and hardware capabilities, and that is where this team works. The Performance Team owns overall system and application performance across that fleet: resource optimization, instrumentation, and the tooling that lets us see what the hardware is actually doing. System memory sits alongside CPU cycles, network processing, and storage IOPS as a first-class resource, and how the kernel manages it is increasingly the thing that decides how hot we can safely run every machine we own. We work upstream first. Several of us maintain or regularly contribute to the Linux kernel, and our default is to fix problems in mainline rather than carry private patches. This role is built on that principle. The problem you would own Using memory efficiently is one of the highest-leverage problems we have. At our scale, how the kernel's memory-management subsystem behaves under pressure has direct consequences for both performance and cost. As DRAM prices climb, getting more out of the memory we already own is a real lever on infrastructure spend. Using custom low-overhead instrumentation on production servers, we have identified several scalability bottlenecks in the kernel memory layer that show up under real workloads. We are looking for an expert to take on these problems, fix them against production workloads, and drive the changes upstream. Solving them lifts efficiency and latency across the entire fleet rather than in one place. What you will do Diagnose and fix performance and scalability bottlenecks in the Linux kernel memory-management subsystem, informed by real production telemetry at a scale few environments can offer. Land your work upstream. We expect MM changes to go to mainline first and want you to keep doing the maintainership and review work that earns standing in the community. Build and extend low-overhead kernel instrumentation (tracepoints, BPF, perf) so we keep measuring before we change, and prove the impact afterwards. Partner with kernel, networking, storage, and product engineers across the company to turn observed system behavior into concrete MM improvements. Set technical direction for how Cloudflare uses, tunes, and evolves kernel memory management as we push utilization higher. Requirements Deep expertise in the Linux kernel memory-management subsystem: the page allocator, virtual memory and memory mapping, reclaim, and the locking and concurrency that hold it together. A track record of upstream Linux contribution, ideally including maintainership or sustained work in MM or an adjacent subsystem. Strong systems programming in C, with the judgement to make high-risk changes to shared infrastructure safely. Ability to dive deep into a complex codebase while keeping the fleet-wide picture in mind, and to own a problem and its outcome rather than a single patch. Clear communication with engineers across many teams, since the symptoms of an MM problem usually show up far from the MM code. Bonuses Strong understanding of Linux kernel internals pertaining to memory management Experience troubleshooting and resolving performance issues in large-scale distributed systems. Experience with large scale configuration/deployment management. What Makes Cloudflare Special? We’re not just a highly ambitious, large-scale technology company.

Location: San Francisco, CA | New York City, NY About Anthropic Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems. About the Role As an AV Engineer focused on Platform & Automation, you'll build and own the software layer of Anthropic's collaboration systems — the tools, integrations, and engineering practices that let a small AV team support a fast-growing global office portfolio. Our rooms, event spaces, and broadcast systems are increasingly managed through APIs and code: device management platforms, DSP and control systems, conferencing administration, ticketing, and paging. Your job is to turn that surface into reliable, team-owned tooling, and to bring software engineering discipline to how we build and maintain it. You can expect a lot of your time writing, shipping, and operating code — fleet health monitoring, automated room testing and ticketing, integrations between our AV platforms and IT systems, and the internal tools that AV Engineering, AV Operations, and Events rely on every day. You'll also help own the administration of the software platforms we already run, and set the standards for how the team version-controls, reviews, tests, releases, and maintains everything from DSP designs to firmware to internal services. Responsibilities Design, build, and ship internal tools and integrations that monitor, test, and manage AV and collaboration systems across every office Develop fleet health monitoring and automated room testing that catch failures before users report them and open actionable tickets automatically Build integrations across device and platform APIs — Q-SYS (including plugins and Lua control scripts), Logitech Sync, Google Meet hardware, digital signage; and IT systems such as Jira, Slack, PagerDuty, and Google Workspace Automate repetitive operational work: provisioning, configuration baselines, drift detection, certificate renewal, and asset data — with code others can read, test, and maintain Own administration and lifecycle of the software platforms behind the AV estate, including firmware and software release management with staged rollouts and rollback plans Operate internal tools as production services, with monitoring, alerting, service metrics, and runbooks, on team-owned repositories and service identities so nothing depends on one person Establish the team's engineering practices: source control, code review, testing, CI/CD, and release — and bring AV configuration under version control, with standards set for integrator deliverables and acceptance verified before changes land Enable AV Engineers, Operations Specialists, and Production staff to contribute safely through templates, guardrails, and review paths built for non-developers Partner with Security, IT Engineering, and Network on least-privilege API access, secrets management, and integration with enterprise standards Gather requirements from AV Operations, Events, and AV Engineering, prioritize the tooling roadmap by operational impact, and decide where to build, buy, or push a vendor to close a gap You May Be a Good Fit If You: Have 10+ years of experience across AV, collaboration, or IT systems engineering, including 4+ years writing, shipping, and maintaining production code that other people depend on Are fluent in at least one general-purpose language: Python, Lua, Go, TypeScript, or similar — and comfortable with shell scripting Practice engineering fundamentals by default: Git-based workflows, code review, automated testing, CI/CD, logging, and observability Understand how AV and collaboration systems work: DSP and control, conferencing platforms, room devices, signal flow, AV-over-IP — well enough to build reliable tools on top of them Have built integrations against REST APIs, webhooks, and vendor SDKs, and know how to handle auth, rate limits, pagination, retries, and partial failure Have owned a tool or service in production over time, not just written it, including fixing it when it broke and handing it off cleanly Have defined engineering practices for a team, especially one where most contributors aren't developers Turn operational pain into well-scoped tooling, and can say no to work that shouldn't be built Thrive in a fast-moving environment where standards are being written rather than inherited Strong Candidates May Also Have Experience With: Q-SYS Lua scripting and plugin development Logitech Sync and CollabOS, and Google Meet hardware administration through the Google Admin console and Admin SDK Google Workspace APIs, GCP (Cloud Run, Cloud Scheduler, Pub/Sub, Secret Manager), and Terraform or other infrastructure-as-code Jira, Slack, and PagerDuty APIs and automation Crestron, Extron, or other control system programming Dante, AES67, NDI, and network fundamentals for AV-over-IP, including multicast, VLANs, and QoS Building with LLMs — agentic automation, LLM-assisted internal tools, or MCP integrations Monitoring and alerting stacks such as Prometheus and Grafana, and containerized deployment Q-SYS Level 2, CTS, or equivalent demonstrated capability Role Specific Location Policy: This role will be based in our San Francisco or New York City office This role is expected to be in office 50% of the time Up to 4 weeks of domestic and international travel annually for platform rollouts, new-office readiness, and on-site testing Business-hours escalation coverage for the tools and platforms this role owns Deadline to apply: None.

Location: San Francisco Workplace: OnSite ABOUT US: AI NEEDS A NEW INFRASTRUCTURE LAYER. WE'RE BUILDING IT AT MODAL. Every era of computing brought new workloads that previous infrastructure couldn't support: mainframes, databases, and the cloud. Each time, the company that rebuilt the layer underneath defined the decade. AI is no different, except it touches everything instead of one slice, and the window to build the layer underneath it is open right now. Our customers include category-defining companies like Ramp https://modal.com/blog/how-ramp-built-a-full-context-background-coding-agent-on-modal, Cognition, DoorDash, and Suno. They rely on Modal for instant GPU access, sub-second container starts, and native storage, so it's simple to serve low-latency inference, fine-tune models, and access production-ready sandboxes at scale. We've passed $1B in annualized run rate, up 15x from a year ago. In October 2026 we raised a $750M Series D led by Accel at a $15.75B valuation. Our team includes creators of popular open-source projects (e.g.,Seaborn https://github.com/mwaskom/seaborn,Luigi https://github.com/spotify/luigi), academic researchers, international olympiad medalists, and experienced engineering and product leaders with decades of experience. THE ROLE: Modal’s Inference Runtime team owns the container runtime stack used to run inference and training workloads across our fleet. We work at the boundary of Linux, containers, filesystems, storage, GPU drivers, and distributed systems. Our goal is to make demanding ML workloads start quickly, run efficiently, and remain securely isolated, whether they use a single GPU, hundreds of gigabytes of memory, or multiple GPUs connected with RDMA. We’re looking for a systems engineer who enjoys working deep in the stack. You’ll build production runtime infrastructure in Rust and Go, diagnose difficult Linux and performance problems, and help determine the architecture of Modal’s container platform. You’ll also work closely with maintainers of gVisor and contribute to the runtime itself when the right fix belongs upstream. WHAT YOU'LL WORK ON: - Make container startup, checkpoint, and restore dramatically faster for large inference and training workloads - Build multi-GPU and accelerator-aware snapshotting, including efficient handling of GPU memory and RDMA-enabled workloads - Design zero-copy and low-copy data paths between container memory, filesystems, storage, and Modal’s runtime - Optimize large snapshot pipelines using techniques such as parallel uploads, direct I/O, incremental snapshots, and more efficient memory handling - Improve container image and filesystem performance across EROFS, FUSE, page caches, overlay filesystems, and remote storage - Extend our sandboxed runtime to support new GPUs, drivers, profiling tools, and device capabilities across NVIDIA and AMD hardware - Debug complex failures involving system calls, virtual memory, process lifecycle, kernel behavior, GPU drivers, and container isolation - Safely roll out runtime and kernel changes across a heterogeneous fleet using compatibility controls, scheduling constraints, feature flags, and observability - Work across the runtime, scheduler, storage, and GPU infrastructure, and take ambiguous production problems from investigation through deployment YOU MAY BE A FIT IF: - You have strong Linux systems knowledge, particularly processes, virtual memory, filesystems, system calls, scheduling, namespaces, cgroups, and signals - You’ve built or debugged container runtimes, sandboxes, the Linux kernel, or similarly low-level infrastructure - You have strong programming ability in Rust, Go, or another systems language, and an interest in becoming productive in both Rust and Go - You’ve profiled and improved systems where memory movement, I/O, synchronization, or kernel interactions dominate performance - You’re comfortable debugging across abstraction boundaries, from application behavior down through runtimes, drivers, and the kernel - You can turn loosely defined production problems into well-designed, reliable systems - You want to own important infrastructure and work closely with both internal teams and customers NICE-TO-HAVE: Any of the following would be helpful, but none is required: - gVisor, runsc, runc, OCI runtimes, seccomp, or checkpoint/restore systems - Linux kernel development, virtualization, sandboxing, kernel modules, or device proxying - CUDA, ROCm, GPU drivers, accelerator virtualization, or GPU profiling - RDMA and high-performance networking - FUSE, EROFS, direct I/O, mmap, page-cache behavior, or storage engines - Large-memory or multi-GPU inference and training systems - Contributions to open-source systems software Prior gVisor or machine-learning experience is not required. We care more about strong systems fundamentals, curiosity, and the ability to learn unfamiliar parts of the stack. WHY THIS ROLE: The container runtime is directly on the critical path for inference performance. Improvements here can substantially reduce cold starts, increase token throughput, unlock new accelerator types, and make previously impractical workloads possible. This is an opportunity to work on unusually deep systems problems with immediate production impact. You’ll have room to shape the architecture, contribute to open-source runtime technology, and take ownership of foundational infrastructure used by every inference and training workload on Modal.

Location: Hybrid About Us At Cloudflare, we are on a mission to help build a better Internet. Today the company runs one of the world’s largest networks that powers millions of websites and other Internet properties for customers ranging from individual bloggers to SMBs to Fortune 500 companies. Cloudflare protects and accelerates any Internet application online without adding hardware, installing software, or changing a line of code. Internet properties powered by Cloudflare all have web traffic routed through its intelligent global network, which gets smarter with every request. As a result, they see significant improvement in performance and a decrease in spam and other attacks. Cloudflare was named to Entrepreneur Magazine’s Top Company Cultures list and ranked among the World’s Most Innovative Companies by Fast Company. At Cloudflare, we’re not looking for people who wait for a polished roadmap; we’re looking for the builders who see the cracks in the Internet that everyone else has simply learned to live with. We value candidates who have the instinct to spot a "normalized" problem and the AI-native curiosity to create a solution using the latest tools. Our culture is built on iteration, leveraging AI to ship faster today to make it better tomorrow, while ensuring that every improvement, no matter how small, is shared across the team to lift everyone up. If you’re the type of person who values curiosity over bureaucracy, and that AI is a partner in solving tough problems to keep the Internet moving forward, you’ll fit right in. Available Location: Austin Job Title: Senior Software Engineer, Cloudflare for SaaS Role Summary Cloudflare for SaaS lets SaaS providers offer their services on domains branded for each customer, rather than on the provider's own domain. The product powers customer domains and automates the complex work behind onboarding domains, validating ownership, issuing and renewing certificates, and safely deploying configuration across Cloudflare's global network. The team builds the APIs and control-plane systems used by some of the world's largest platforms. We are evolving these systems to support tens of millions of customer domains, faster and more reliable APIs, simpler configuration at scale, and more Cloudflare products for each customer domain. This work combines customer-facing product development with challenging problems in distributed systems, data modeling, state consistency, observability, and operational reliability. Cloudflare is looking for a Software Engineer to design, build, and operate the services behind Cloudflare for SaaS. You will work primarily on backend services and RESTful APIs in Go and other languages, modernize legacy control-plane workflows, and improve the reliability and scalability of production systems.

What You'll Do Design, build, and operate reliable backend services and APIs for managing customer domains and their configuration. Evolve the control plane to support tens of millions of customer domains without sacrificing correctness, availability, or API performance. Improve certificate and domain lifecycle workflows, including onboarding, validation, renewal, migration, and safe deletion. Model ownership and shared state carefully so changes remain consistent across distributed services and configuration stores. Build useful observability, alerts, and operational procedures, and participate in debugging and incident response. Collaborate across engineering and product teams, document designs and tradeoffs, and review the work of fellow engineers. Role Requirements (Must-Have Skills) 3+ years of professional experience building backend systems at a technology company. Experience writing production-quality code in Go or another language, with a willingness to learn Go. Experience designing, building, and operating distributed systems or high-scale services. Strong debugging and troubleshooting skills across applications, data stores, and production environments. Proficiency with modern Unix/Linux development and runtime environments. A track record of delivering well-tested, reliable code and taking ownership of it in production. Clear written and verbal communication, including the ability to explain technical decisions and tradeoffs. Desirable Skills, Knowledge, and Experience Experience designing and evolving RESTful APIs used by external customers. Working knowledge of SQL and relational databases such as PostgreSQL, including schema and query design. Understanding of distributed-systems concerns such as consistency, caching, concurrency, and failure recovery. Experience modernizing legacy systems or migrating workflows to a service-oriented architecture. Experience with observability tools and practices, including metrics, logs, tracing, alerting, and SLOs. Familiarity with PKI/TLS, certificate lifecycle management, ACME, DNS, or domain validation. Experience with message queues, Kubernetes, or globally distributed configuration systems. Interest in building intuitive product experiences for customers managing large fleets of domains. What Makes Cloudflare Special? We’re not just a highly ambitious, large-scale technology company. We’re a highly ambitious, large-scale technology company with a soul. Fundamental to our mission to help build a better Internet is protecting the free and open Internet. Project Galileo : Since 2014, we've equipped more than 2,400 journalism and civil society organizations in 111 countries with powerful tools to defend themselves against attacks that would otherwise censor their work, technology already used by Cloudflare’s enterprise customers--at no cost. Athenian Project : In 2017, we created the Athenian Project to ensure that state and local governments have the highest level of protection and reliability for free, so that their constituents have access to election information and voter registration. Since the project, we've provided services to more than 425 local government election websites in 33 states. 1.1.1.1 : We released 1.1.1.1 to help fix the foundation of the Internet by building a faster, more secure and privacy-centric public DNS resolver. This is available publicly for everyone to use - it is the first consumer-focused service Cloudflare has ever released. Here’s the deal - we don’t store client IP addresses never, ever. We will continue to abide by our privacy commitment and ensure that no user data is sold to advertisers or used to target consumers. Sound like something you’d like to be a part of?

If you’re passionate about making a mark in the fintech space, this is your opportunity to collaborate with some of the brightest minds, pushing boundaries and setting new standards. We’ve grown fast, stayed lean, and secured our place as a leader in the industry. If you have excellent English communication skills and are ready to contribute to the most innovative platform on the planet, Tether is the place for you. Are you ready to be part of the future? About the job Keet is a fully peer-to-peer messaging and video calling app built on Holepunch's P2P stack. There are no servers, no middlemen, and no data harvesting. People talk directly to each other, with end-to-end encryption by design. We are looking for a Senior Technical Product Manager to own the vision for Keet and lead it to a billion users, competing head-on with WhatsApp and Telegram. This is not a maintenance role. You will define where Keet goes, convince the board and the team that it is the right direction, and then drive the execution that gets it there. You are a rare combination of three things. You are a product visionary who has shipped consumer chat or calling apps at scale. You are a technologist who can go deep on P2P architecture and the Pear / Holepunch stack (docs.pears.com). And you are a hands-on builder who uses AI tools to prototype and prove concepts in days, not months. You set the bar high, move at incredible speed, and lead from the front. You will also be the person who catches what others miss. The PM who thrives here reads every ticket, tracks every dependency, asks the uncomfortable question before it becomes a launch incident, and keeps five workstreams moving simultaneously without losing the thread on any of them. If you prefer a PM role where you set strategy and delegate execution, this is not the right fit. If you want to build something that ships to real users, moves markets, and carries your fingerprints from concept to production, we want to hear from you. Responsibilities Vision & Strategy Own and articulate the long-term product vision for Keet as the world's leading private, peer-to-peer communication app, with a clear path to 1 billion users. Analyze WhatsApp, Telegram, Signal, LINE, WeChat and emerging competitors to identify where P2P gives Keet an unfair advantage, and build the roadmap around it. Present product vision, strategy, metrics and progress to the board and executive leadership with clarity and conviction. Define a growth strategy across acquisition, activation, retention and virality, with measurable targets at every stage. Technical Product Leadership Develop a deep working understanding of the Holepunch P2P stack (Pear runtime, Bare, Hypercore, Hyperswarm, HyperDHT, Autobase, Hyperbee) and translate its capabilities and constraints into product decisions. Partner with core engineering on hard P2P problems at scale, including NAT traversal, offline sync, multi-device support, large groups, push notifications, and battery and data efficiency on mobile. Own the real-time calling experience (1:1 and group voice and video, plus screen sharing) to a quality bar that matches or beats Google Meet and Zoom. Define clear feature tiers with explicit labels for stable versus experimental functionality. Rapid Prototyping with AI Use AI coding and design tools to build working prototypes and demos that prove concepts before committing engineering resources. Turn ideas into something the team, users and the board can see and touch within days. Execution & Team Leadership Lead the product team and run the sprint cadence end to end, covering planning, prioritization, standups, reviews and retrospectives. Own deliverables from conception through release, testing and post-launch iteration, ensuring core functionality works reliably every time. Maintain issue trackers and roadmaps that accurately reflect priorities and sprint commitments. Coordinate across engineering, QA, design, marketing and business stakeholders, and manage cross-team dependencies across the Holepunch and Tether ecosystem. Provide transparent updates on status, risks and timeline changes, and hold direct conversations about accountability when needed. Mobile & Distribution Own the mobile release process across iOS and Android. This includes App Store and Google Play submissions, review guidelines, compliance, store listings, ratings and release management. Oversee desktop distribution and installers across macOS, Windows and Linux. Build crash reporting, debugging and analytics systems, privacy-preserving by design, that turn user reports into actionable engineering data. Mandatory: 8+ years of product management experience, including significant time in a senior or lead role owning a consumer product end to end. Strong product sense, with a proven track record of setting product vision and driving it to measurable outcomes at scale (tens of millions of users or more). Experience leading engineers who ship products, including running sprint cadences with predictable delivery across cross-functional teams. Deep JavaScript and React skills. You can read and write production code, review pull requests, and build working prototypes yourself. Intuition for distributed and local-first systems. You don't need P2P expertise, because our core abstracts it away, but you should be able to reason about sync, offline behavior and consistency trade-offs. Hands-on experience shipping and scaling mobile apps on iOS and Android, with deep familiarity with App Store and Google Play logistics, review processes and release management. Experience with real-time voice and video calling products (such as Google Meet, Zoom, FaceTime or WhatsApp calls) and the quality, latency and reliability trade-offs involved. Demonstrated ability to use AI tools to rapidly prototype and demonstrate product concepts. Exceptional communication skills, with experience presenting vision and strategy to boards, executives and investors. A strong understanding of urgency versus importance, and the judgment to make fast, high-quality decisions with incomplete information. You thrive in a high-intensity, fast-moving environment, set an exceptionally high bar, and are willing to go above and beyond, including extended hours, when the mission demands it. Excellent written and spoken English. Nice to have: Product leadership experience at a major messaging app such as WhatsApp, Telegram, LINE, WeChat, Signal, Viber or KakaoTalk. Experience with peer-to-peer technologies, distributed systems or decentralized protocols. Prior exposure to Holepunch, Pear or Hypercore is a strong plus. Experience growing a product in emerging markets or across multiple regions and languages. A background in privacy, encryption or security-focused products. Familiarity with Electron, React Native or similar cross-platform frameworks, as well as installer systems, boot performance and Linux packaging (Snap, AppImage, Flatpak). A solid understanding of testing approaches (unit, integration, end-to-end), test automation and performance testing. An engineering background or computer science degree. Experience with Git, issue trackers and modern collaboration tools. Why this role: The next billion-user communication app will not run on someone else's servers. If you want to be the person who defines it, presents it to the board, prototypes it yourself, and then leads the team that ships it, we want to hear from you. In your application, include a link to a product you have shipped or a prototype you have built, along with a few sentences on how you would take Keet to 1 billion users.

Experience with Git, issue trackers and modern collaboration tools. Why this role: The next billion-user communication app will not run on someone else's servers.

About the job Keet is a fully peer-to-peer messaging and video calling app built on Holepunch's P2P stack. There are no servers, no middlemen, and no data harvesting. People talk directly to each other, with end-to-end encryption by design. We are looking for a Senior Technical Product Manager to own the vision for Keet and lead it to a billion users, competing head-on with WhatsApp and Telegram. This is not a maintenance role. You will define where Keet goes, convince the board and the team that it is the right direction, and then drive the execution that gets it there. You are a rare combination of three things. You are a product visionary who has shipped consumer chat or calling apps at scale. You are a technologist who can go deep on P2P architecture and the Pear / Holepunch stack (docs.pears.com). And you are a hands-on builder who uses AI tools to prototype and prove concepts in days, not months. You set the bar high, move at incredible speed, and lead from the front. You will also be the person who catches what others miss. The PM who thrives here reads every ticket, tracks every dependency, asks the uncomfortable question before it becomes a launch incident, and keeps five workstreams moving simultaneously without losing the thread on any of them. If you prefer a PM role where you set strategy and delegate execution, this is not the right fit. If you want to build something that ships to real users, moves markets, and carries your fingerprints from concept to production, we want to hear from you. Responsibilities Vision & Strategy Own and articulate the long-term product vision for Keet as the world's leading private, peer-to-peer communication app, with a clear path to 1 billion users. Analyze WhatsApp, Telegram, Signal, LINE, WeChat and emerging competitors to identify where P2P gives Keet an unfair advantage, and build the roadmap around it. Present product vision, strategy, metrics and progress to the board and executive leadership with clarity and conviction. Define a growth strategy across acquisition, activation, retention and virality, with measurable targets at every stage. Technical Product Leadership Develop a deep working understanding of the Holepunch P2P stack (Pear runtime, Bare, Hypercore, Hyperswarm, HyperDHT, Autobase, Hyperbee) and translate its capabilities and constraints into product decisions. Partner with core engineering on hard P2P problems at scale, including NAT traversal, offline sync, multi-device support, large groups, push notifications, and battery and data efficiency on mobile. Own the real-time calling experience (1:1 and group voice and video, plus screen sharing) to a quality bar that matches or beats Google Meet and Zoom. Define clear feature tiers with explicit labels for stable versus experimental functionality. Rapid Prototyping with AI Use AI coding and design tools to build working prototypes and demos that prove concepts before committing engineering resources. Turn ideas into something the team, users and the board can see and touch within days. Execution & Team Leadership Lead the product team and run the sprint cadence end to end, covering planning, prioritization, standups, reviews and retrospectives. Own deliverables from conception through release, testing and post-launch iteration, ensuring core functionality works reliably every time. Maintain issue trackers and roadmaps that accurately reflect priorities and sprint commitments. Coordinate across engineering, QA, design, marketing and business stakeholders, and manage cross-team dependencies across the Holepunch and Tether ecosystem. Provide transparent updates on status, risks and timeline changes, and hold direct conversations about accountability when needed. Mobile & Distribution Own the mobile release process across iOS and Android. This includes App Store and Google Play submissions, review guidelines, compliance, store listings, ratings and release management. Oversee desktop distribution and installers across macOS, Windows and Linux. Build crash reporting, debugging and analytics systems, privacy-preserving by design, that turn user reports into actionable engineering data. Mandatory: 8+ years of product management experience, including significant time in a senior or lead role owning a consumer product end to end. Strong product sense, with a proven track record of setting product vision and driving it to measurable outcomes at scale (tens of millions of users or more). Experience leading engineers who ship products, including running sprint cadences with predictable delivery across cross-functional teams. Deep JavaScript and React skills. You can read and write production code, review pull requests, and build working prototypes yourself. Intuition for distributed and local-first systems. You don't need P2P expertise, because our core abstracts it away, but you should be able to reason about sync, offline behavior and consistency trade-offs. Hands-on experience shipping and scaling mobile apps on iOS and Android, with deep familiarity with App Store and Google Play logistics, review processes and release management. Experience with real-time voice and video calling products (such as Google Meet, Zoom, FaceTime or WhatsApp calls) and the quality, latency and reliability trade-offs involved. Demonstrated ability to use AI tools to rapidly prototype and demonstrate product concepts. Exceptional communication skills, with experience presenting vision and strategy to boards, executives and investors. A strong understanding of urgency versus importance, and the judgment to make fast, high-quality decisions with incomplete information. You thrive in a high-intensity, fast-moving environment, set an exceptionally high bar, and are willing to go above and beyond, including extended hours, when the mission demands it. Excellent written and spoken English. Nice to have: Product leadership experience at a major messaging app such as WhatsApp, Telegram, LINE, WeChat, Signal, Viber or KakaoTalk. Experience with peer-to-peer technologies, distributed systems or decentralized protocols. Prior exposure to Holepunch, Pear or Hypercore is a strong plus. Experience growing a product in emerging markets or across multiple regions and languages. A background in privacy, encryption or security-focused products. Familiarity with Electron, React Native or similar cross-platform frameworks, as well as installer systems, boot performance and Linux packaging (Snap, AppImage, Flatpak). A solid understanding of testing approaches (unit, integration, end-to-end), test automation and performance testing. An engineering background or computer science degree. Experience with Git, issue trackers and modern collaboration tools. Why this role: The next billion-user communication app will not run on someone else's servers.
