Location: Remote (United States) Thank you for considering Tailscale. If this job description resonates with you, please apply. Frequently cited statistics show that people who identify with historically marginalized groups are likely to apply to jobs only if they meet 100% of the qualifications. We encourage you to help us break that statistic! About Tailscale Tailscale is making safe connection effortless by delivering software that makes it easy to securely interconnect people and their devices, no matter where they are. From hobbyists to multinational corporations, teams of every size use Tailscale each day to protect their networks, share access to internal tools, and more. We're building a future for the Internet that's easy, sensible, and safe, like it used to be. Founded in 2019 and fully distributed, we're backed by Accel, CRV, Insight, Heavybit, and Uncork Capital. About the Role Join our Strategic Projects team, reporting to the team's Engineering Manager and ultimately into our co-founder and Chief Strategy Officer. This team exists to show developers and organizations why Tailscale should be their default connectivity substrate, both for internal infrastructure and for embedding into customer-facing products. Aperture, our identity-aware LLM gateway, is one such initiative. This is an AI-native team. We use coding agents heavily as a force multiplier and expect every engineer to be a power user. Our customers demand a high bar on code quality, security, and operational rigour, and we treat that as a reason to use every tool available, including LLMs and coding agents, to ship fast without compromising it. We move fast from idea to prototype, and we're growing the side of the team that's energized by the path from prototype to dependable product. You'll work shoulder-to-shoulder with product-minded engineers from the moment an idea takes shape, shaping how it's built so it holds up later, and co-owning the work of making it production-grade: stable, observable, maintainable, and ready for real customer load. You're the kind of engineer who finds the long tail of development genuinely satisfying, the edge cases, the failure modes, the tests and runbooks, the details that turn a sharp demo into something customers can rely on. You'll work directly with reference customers on integrations and own the production bar on prototypes that graduate into Tailscale's product surface area, ensuring the security, review, and operational practices that wrap around agent-generated code actually hold in production. Tailscale is fully remote, this team operates with significant ambiguity, and the shipping cadence is fast. Comfort working asynchronously and collaborating with highly technical customers is essential. Key Responsibilities Partner with product-minded engineers from the start, shaping prototypes (MCP gateways, LLM proxies, sandboxes, remote servers, and similar emerging workloads) so the path to production is built in, not bolted on. Co-own the journey from "works in a demo" to "stable in production": hardening, error handling, observability, and operational tooling. Own the production bar on prototypes that graduate into Tailscale's product surface area, including the security and review practices that wrap around agent-generated code. Work with reference customers to integrate Tailscale, both for internal adoption (VPN replacement with identity-aware networking) and for embedding into their products, with particular attention to reliability, maintainability, and long-term supportability. Find and close the long-tail gaps, edge cases, regressions, flaky behavior, missing tests, undocumented operational knowledge, that separate a prototype from a dependable product. Establish and maintain the review, testing, and security practices that let the team ship agent-generated code fast without compromising the production bar. Light travel required (<10%): primarily team and company onsites, with optional conferences or customer visits concentrated in North America. What We Are Looking For Ideal candidates will have experience taking software from prototype to production in startup-like environments. We don't expect expertise with every aspect listed below. Let us know where you feel you have the most experience and where you'd like to keep developing. Strong at hardening, stabilizing, and maintaining production software; you take satisfaction in detail-oriented work and in closing the long tail of bugs, edge cases, and operational gaps. Go experience is a must; comfort integrating third-party APIs; basic networking. Heavy daily use of coding agents (Claude Code, Cursor, or similar) and LLMs in your engineering workflow, with a point of view on where they accelerate work, where they fail, and especially how to wrap them in the review, testing, and security practices that hold the production bar. Enjoy collaborating closely with exploratory, product-minded engineers and jointly owning the work of getting something solid into production. Comfort with the cadence of a strategy team at an early-ish startup: priorities shift with market signal, prototype-to-production timelines are short, and the bar on what ships stays high regardless. Thrive working independently in a remote environment. Nice to Have Experience operating production services: observability, on-call, incident response, performance and reliability work. Validating prototype code for production use alongside security teams. Identity infrastructure: IdP platforms, identity sync/provisioning, directory services; authentication protocols (OAuth, OIDC, SAML, SCIM); access control models (RBAC/ABAC), session management, MFA, passwordless auth. Building applications on top of LLMs and agentic systems (not just using them as dev tools). Familiarity with Tailscale itself and with networking challenges in multi-cloud and hybrid deployments. Open source community participation; experience producing publicly-visible artifacts (blog posts, talks, reference implementations). Python, Rust, and/or TypeScript. Why You'll Enjoy Working With Us Work shoulder-to-shoulder with sharp engineers to turn promising prototypes into products customers depend on. Work alongside reference customers on real integrations rather than abstract roadmaps. Shape emerging AI connectivity standards and Tailscale's product strategy.

Location: London Workplace: OnSite ABOUT APTURA We build the evaluation datasets and RL environments that make AI reliable in domains where mistakes are expensive: finance, healthcare, and legal. Our team designs expert-curated training data, calibrated rubrics, and verifiable task environments for AI labs and startups pushing the frontier of what models can do in regulated industries. We're a small, lean, London based team that moves fast and takes the work seriously. Everyone contributes directly. Initiative is rewarded, and ownership is the default. If you want to shape how frontier AI learns to operate in the real world, we'd like to hear from you. ABOUT THE ROLE As a Member of Technical Staff on our Software Engineering team, you will build the platform that powers how Aptura operates and scales — the annotation tooling, workflow systems, quality control pipelines, and internal infrastructure that sit behind every dataset and environment we ship. Day to day, that looks like: designing expert task creation flows, building task assignment and review interfaces, writing the data pipelines that move outputs from domain experts into structured training sets, and integrating LLM-powered tooling directly into the product. Some days it's product engineering. Some days it's closer to infrastructure. The common thread is that the software you build is what lets a small team produce high-quality evaluation data at scale. You'll be the person who makes the platform real. Decide what gets built, how it gets built, and set the standard for how we build as we grow. WHAT YOU'LL DO - Build and own the core data annotation and workflow platform end to end — from task assignment and expert interfaces to quality control and dataset delivery - Design systems that support expert onboarding, task routing, review workflows, and QA at scale - Build and improve AI-integrated pipelines across the platform, including LLM-assisted annotation, automated checking, and model-in-the-loop workflows - Work directly with founders and domain operators to turn manual, bespoke processes into reliable, scalable software - Make strong product and engineering decisions in ambiguous, fast-moving situations — scoping, prioritising, and shipping without waiting for perfect specs - Help define how we build as a team: tooling choices, engineering standards, and product direction WHO WE'RE LOOKING FOR You will not be a good fit if you thrive in well-defined scopes and prefer a clear spec before moving. We are looking for people who are comfortable identifying what needs building, making a call, and shipping — often before the full picture is clear. You will not be a good fit if you like to go deep on one technical area for an extended period. We are looking for people who are energised by moving across product, infrastructure, data systems, and AI tooling — sometimes all in the same week. You will not be a good fit if you prefer to hand work off at the boundaries of your role. We are looking for people who want to own problems end to end, from the first conversation through to something live. You will not be a good fit if you aren't yet integrating AI into how you build day to day. We are looking for people who are already using LLMs and coding agents as part of how they work, and are excited to push that further. You will not be a good fit if you think of speed and quality as things you trade off against each other. We are looking for people who don't cut corners — they cut scope. We don't care about background, experience, or prestige. We want people who can demonstrate they will work hard, learn fast, and ship things that matter. Former founders, early engineers at startups, and people with infrastructure experience are a plus. NICE TO HAVE - Experience building internal tools, annotation platforms, workflow software, or operations-heavy products - Familiarity with modern product stacks: React, Next.js, TypeScript, Node.js, FastAPI, or similar - Exposure to AI products, LLM tooling, or evaluation workflows - Domain interest in finance, healthcare, or legal - Previous experience as an early or founding engineer On-site in London. Compensation (salary + equity) will be competitive.

Location: Ho Chi Minh City, Vietnam Insurance is one of the world's largest industries and one of the most painful to interact with . Paper forms. Sluggish call centres. Three-week underwriting cycles. Claims that vanish into queues. We are rebuilding all of it on top of a modern platform and AI agents that actually do the work, not pretend to. You will not be picking up tickets. You will be deciding what to build, prototyping it on Monday, shipping a draft to a real customer by Friday, and improving it from real usage. We expect you to push the product, the codebase, and the way we work. Why This Role Exists We are looking for someone who treats AI as a creative material, not a feature on a roadmap. The next year of insurance is being defined right now. What gets automated, what gets reimagined, what gets thrown out. We want builders who want to be in that room and ship the answer. The team is small. The mandate is large. If your highest-energy work has historically come from solving real problems end to end, this is the seat. What You Will Do Own outcomes, not tickets. Pick the biggest lever for our customers each sprint and drive it to live. Surface the next one yourself. Build with AI as a primary tool, not a chatbot bolt-on. OCR, document understanding, generation, agent loops, evaluation harnesses. You decide where each fits. Ship prototypes fast, then make them production-grade. A working demo on day three beats a perfect plan on day ten. Work directly with customers. You will see real claims, real underwriting screens, real broker workflows. You will watch users hit dead ends and decide what to fix. Raise the bar on the codebase. Reviews, refactors, testability, observability. Not as policy, as habit. Push the team forward. Skills, agents, internal tools, engineering standards. Propose them, build them, get them adopted. Who You Are You ship. Ideas without execution do not count for you. High agency. You do not wait for a card to be assigned. You see what is worth doing and you start. Strong opinions, loosely held. You make calls with incomplete information and change your mind when the evidence shifts. Curious about the domain. Insurance is messy and full of weird incentives. That intrigues you, not annoys you. Fluent with AI. You have shipped something real with LLMs or agents. You know where the magic ends and where you have to engineer carefully. Care about humans on the other end. Insurance done right gives people peace of mind in their worst weeks. That is the point. Your Toolbox We use Node.js + TypeScript + Nest.js on the back end, Vue (and some React) on the front end, GraphQL, MongoDB, Docker, AWS. AI work spans OpenAI, Anthropic, Google, plus a growing set of in-house skills and agents. You do not need to have used every piece. You do need to be the kind of engineer who picks up a new tool and is shipping with it within the week. What We Expect at This Level 6+ years building production systems. Track record of complex, customer-facing software shipped, not just maintained. Real AI experience. You have built and shipped at least one substantive AI-driven feature. POCs that died in a notebook do not count here. Strong fundamentals. OO, design patterns, testing, web security, performance. You do not need a refresher. Cloud comfort. AWS, Azure, or GCP. At least one in depth, the rest enough to hold a conversation. Communication. You can explain a tradeoff to a non-technical stakeholder in two minutes and to an engineer in one. Not Suitable for the Role If… You prefer tickets assigned to you over choosing what to build. You measure your work in lines of code, not outcomes. You see AI as a buzzword to put on your CV rather than a tool you have actually used in anger. You want a process-heavy environment with detailed specs handed down from product. You are looking for a maintenance role on a finished platform. Why CoverGo Insurance is the rare industry where AI can save people hours of their worst weeks. We are already shipping AI-powered claims, underwriting, distribution, and document automation to enterprise carriers across five continents. The platform is real. The customers are real.

Workplace: fully Role Overview We're building a new engineering team at Ethena to own Ethena Pay neobanking style app built on top of our stablecoin infrastructure. As the Staff/Senior Engineer, you own the correctness and evolution of the money-paths at the core of the product — payments, payouts, deposits, transfers, and reconciliation — and the app-facing APIs and authentication backend the native mobile app depends on. Your north star: money always moves correctly, exactly once, and observably; and every request the Ethena Pay app makes is fast, well-versioned, and secure. This is a senior IC role with real design authority over the backend — you set the standard for how these services are built, not just execute tickets. Role Responsibilities Design, build, and own complex backend systems for a high usage consumer app. Own the app-facing API contract as a product: versioned, backward-compatible endpoints with client idempotency keys, a consistent error model, and clean pagination, built in partnership with the iOS team. Own the authentication and authorization backend, including the passkey/WebAuthn relying party, session/token lifecycle, and authorization enforcement at every API boundary. Defend the auth surface against abuse through rate limiting, anomaly detection, and secure handling of PII and secrets. Set patterns, tests, and documentation so the backend can be safely extended by any engineer, raising the correctness, testing, and security bar by example and in review. Trace and document money-paths end-to-end, from API through wallet/executor/submitter/indexer, event streams, and on-chain settlement, closing real correctness and reliability gaps as you go. Ship fast, test-first. Deliver on a tight cadence with test-driven and behaviour-driven development — you can prove the correctness of a payout path, not just its happy path. Required Skills and Experience Proven experience building and operating backend systems that move real money in production — payments, exchange/settlement, lending, banking, or crypto — with a track record of preventing (or fixing) idempotency, rounding, or reconciliation bugs. Experience designing and owning client-facing APIs consumed by a mobile app at scale: contracts, versioning and backward compatibility, idempotency keys, error models, pagination, and rate limiting. Experience building or operating an authentication/authorization backend — OAuth2/OIDC, JWT session/token lifecycle, RBAC/ABAC scopes, MFA/step-up — ideally including a WebAuthn/passkey relying party. Hands-on integration with real financial third parties end-to-end (card issuing, KYC/fiat ramp partners, or payments/settlement providers), including their webhooks, failure modes, and reconciliation. On-chain settlement literacy from the backend — nonces, gas, reorgs, RPC failure, confirmation depth — treating chain data as untrusted input. Strong TypeScript (or a fast, credible path from Go/Kotlin/Rust/Java), with Postgres, an event/queue system (NATS/Kafka/SQS-class), and gRPC-based service-to-service communication at production scale. A test-first culture matching ours — BDD/integration testing with real dependencies (Testcontainers-style) — and fluency with agentic development workflows (Claude Code, MCP, skills) as a core part of how you engineer.
