THE TEAM AND YOUR IMPACT As our Senior Developer Relations Engineer in San Francisco, you'll lead Qdrant's developer engagement in one of the most active AI communities in the world. In this senior individual contributor role, you'll combine hands-on engineering (about 40% of your time) with public speaking, content, and community building (about 60%). Your impact will show up in two places. Externally, you'll turn your Bay Area relationships with engineers, founders, and event organizers into joint projects and workshops with our ecosystem partners, while your talks at premier conferences and your technical content reach hundreds of thousands of developers worldwide. Inside Qdrant, you'll bring what you hear from developers directly to our core engineering team to shape the roadmap, and you'll raise the bar for the DevRel team by starting new initiatives and mentoring others. WHAT YOU WILL OWN - Demos and applied research. Build and maintain open-source demo applications, such as end-to-end retrieval pipelines, recommendation engines, and AI search tools. Prototype new Qdrant use cases by experimenting with emerging patterns like neural sparse encoders, agentic workflows, and AI memory. - Technical content. Write in-depth technical articles, record video tutorials, and create practical guides that make complex concepts easy to follow. - Talks, events, and Bay Area partnerships. Give talks and live coding sessions at conferences, and lead Qdrant's presence at hackathons and workshops. Work with our partnerships team to turn local relationships into joint workshops, demos, and speaking opportunities. - Developer community. Answer technical questions on Discord, X, LinkedIn, and Reddit, and bring what developers need back to our product and engineering teams. WHO YOU ARE - Senior DevRel experience.

You've independently delivered technical talks, workshops, and community programs, and you can share examples of working applications and collaborations you started. - Technical depth and clear communication. You have strong software engineering skills in Python, Rust, TypeScript, or Go. You can build and debug applications that use vector search, embeddings, and large language models, and explain the "how" and "why" behind them, whether in writing or on stage. - Ownership of outcomes. You've owned a DevRel program or initiative end to end: you set the goals, chose what to build or say, and measured whether it worked, for example through adoption, community growth, or content reach. You can walk us through what you changed based on the results. - Influence beyond your own work. You've changed a product or engineering decision based on developer feedback, and you've helped other team members grow through mentoring, reviews, or shared practices. - Established San Francisco network. You're an active part of the Bay Area developer and AI community, with real relationships among engineers, event organizers, and founders. - Judgment and empathy for developers. You follow the AI ecosystem closely, test new tools for their practical value, and can tell useful technical work from hype. You understand what developers need and use that to choose topics and create content that respects their knowledge. NICE TO HAVE - Search and retrieval depth. You've worked on search or information retrieval systems, or at a search company, and understand how indexing, ranking, and relevance tuning work under the hood. - Applied research. You go deeper than tutorials. You read papers, run experiments or benchmarks, and turn what you find into something developers can use. - Video and social reach. You've built an audience through video or social media, for example YouTube tutorials, livestreams, or technical posts on X or LinkedIn. WHY JOIN US - A remote-first, international team working on cutting-edge AI infrastructure. - A competitive salary with additional perks. - Flexible working hours and async-friendly culture. - High ownership and real impact. - Open-source, engineering-driven culture. - Choose your own laptop equipment.

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?

How we're different We believe that the highest-impact AI research will be big science. At Anthropic we work as a single cohesive team on just a few large-scale research efforts. And we value impact — advancing our long-term goals of steerable, trustworthy AI — rather than work on smaller and more specific puzzles. We view AI research as an empirical science, which has as much in common with physics and biology as with traditional efforts in computer science. We're an extremely collaborative group, and we host frequent research discussions to ensure that we are pursuing the highest-impact work at any given time. As such, we greatly value communication skills. The easiest way to understand our research directions is to read our recent research. This research continues many of the directions our team worked on prior to Anthropic, including: GPT-3, Circuit-Based Interpretability, Multimodal Neurons, Scaling Laws, AI & Compute, Concrete Problems in AI Safety, and Learning from Human Preferences. Come work with us! Anthropic is a public benefit corporation headquartered in San Francisco. We offer competitive compensation and benefits, optional equity donation matching, generous vacation and parental leave, flexible working hours, and a lovely office space in which to collaborate with colleagues.

Location: Brazil; Peru; Colombia; Argentina; Mexico; Chile Workplace: Remote BUILDING THE FUTURE OF OPEN FINANCE Payward - the parent company behind Kraken, NinjaTrader, Breakout, xStocks, Payward Services and CF Benchmarks - has spent the last 15 years building one of the most modern and globally accessible financial infrastructure platforms in the industry, built to advance an open, global financial system. THE TEAM Founded in 2011, Kraken is one of the world's longest-standing crypto platforms, trusted by over 10 million individuals and institutions across the globe. It offers spot trading, margin, futures, staking, and OTC services, with products built for both individual investors and institutional clients. Kraken's engineers build a lot of software. Developer Platform AI builds the AI systems they use to do it: agents that write and review code, simple access to the best models in the tools they already use, and the infrastructure that connects AI to our internal systems. This is a small team with a lot of reach. The tools you ship will change how engineers across Kraken work every day, and you'll see that happen directly. The work spans agent platforms, code review, LLM routing and cost controls, MCP integrations with tools like Slack, Jira and GitLab, and the security and observability that make all of it safe to run. If you want to work on applied AI with real users from day one, this is that job.   THE OPPORTUNITY - LLM traffic doesn't behave like normal API traffic. Requests are long-running, streaming and expensive. One prompt can cost a few cents or a few dollars. One team's burst can burn another team's budget. Providers change their rate limits, failure modes and pricing without warning. Running this well is a problem few companies have solved, and it's the job. - Own the reliability of the platform engineers depend on: the AI Gateway, the agent runtime and the connections to internal tools. Set the SLOs, own the error budgets and decide what happens when they're spent. - Design resilience across model providers: routing, failover, retries, rate limiting and graceful degradation when a provider is slow, throttling or down. - Make LLM traffic legible. Build observability that shows latency, errors, token usage and cost by team, model and use case, so engineers can see what their workloads cost and where they're spending their time waiting. - Treat capacity and cost as one problem. Routing decisions affect both latency and spend, and you'll own the tradeoff directly. - Work with Security, Finance and AI governance to put access controls, budgets, audit logging and data handling into the platform, not into a spreadsheet next to it. - Lead incident response and blameless post-incident reviews. Turn what breaks into fixes that stay fixed. - Automate operations with infrastructure as code, safe deployments and progressive rollouts, so the platform gets more reliable as it grows rather than more fragile. - Mentor engineers and raise the operating standard across the team. This is a Staff role. You'll set the technical direction for how the platform runs, not just keep it running. The platform is small enough that your decisions shape it directly, and used broadly enough that they affect every engineering team at Kraken. SKILLS YOU SHOULD HODL - Extensive experience in site reliability, infrastructure or platform engineering, with a track record of owning high-traffic, business-critical services in production - Deep hands-on experience with Kubernetes, a major cloud provider and infrastructure as code such as Terraform - Strong command of SLOs, observability and incident management, and the judgment to know which reliability work actually matters - Proficiency in Rust or Python, and comfort reading and changing a production service's code - Experience with API gateways, reverse proxies or traffic management: load balancing, rate limiting, failover and caching - Experience operating multi-tenant internal platforms, including authentication, authorization and per-tenant cost controls - Staff-level influence: you set direction across teams, write clear design documents and bring other engineers with you NICE TO HAVES - Experience operating LLM gateways or integrating LLM provider APIs at scale: streaming, token-based rate limiting, model routing and caching - Experience serving models yourself, including vLLM or Ray: GPU scheduling, batching, autoscaling and cost per token - Experience building Kubernetes controllers or operators with controller-runtime or kubebuilder - Experience with Consul and Vault for service discovery, configuration and secrets - Experience with model evaluation pipelines for catching quality regressions before and after rollout - Familiarity with coding agents and agent harnesses, and running them safely in sandboxed environments - Experience with cost attribution, budgeting or FinOps for usage-based services - Background in security-sensitive or regulated environments such as financial services or crypto - Contributions to open-source gateway, proxy or observability projects Unless a specific application deadline is stated in the job posting, applications are accepted on an ongoing basis. Please note, applicants are permitted to redact or remove information on their resume that identifies age, date of birth, or dates of attendance at or graduation from an educational institution. We consider qualified applicants with criminal histories for employment on our team, assessing candidates in a manner consistent with the requirements of the San Francisco Fair Chance Ordinance. OUR COMMITMENT Payward is powered by people from around the world and we celebrate the diverse talents, backgrounds, contributions, and unique perspectives that everyone brings to the table.
