You will need to rate your English 1 to 6, and we are looking for 4 or higher.Enter applicationWhy OpenRelayOpenRelay is GPU compute and LLM inference for people who ship.

Customers rent GPU machines and call inference APIs; providers plug their hardware into our network and get paid for it. We run a distributed fleet on real hardware, not a reseller skin over someone else's cloud. Small team, high bar, and room for A-players to own things that are live in production.No degree required, show us what you have builtWe care about what you can do, not diplomas. The profile we want most is simple: you built something on the web, and then you got strangers to use it.

That last part is everything. Plenty of engineers can ship a site. Figuring out how people actually find it, ranking for a query that matters, writing cold email that gets replies, launching somewhere and converting the traffic, is the rarest and most valuable skill you can bring us. Show us what you built and the users you got on it: real traffic, real signups, real revenue.Core techNext.js + React (TypeScript), TailwindtRPC, Node.jsGo (control plane, gateways, CLI)DynamoDB, RedisAWS (ECS Fargate, Terraform), Docker, LinuxPostHog, VercelClaude Code and agentic tooling, dailyWhat you will buildYou will own features end to end in one of three tracks, though at a startup you will touch all of them: fullstack engineering across the dashboard, marketing site, docs and ops portal; platform and infrastructure work on the Go control plane that schedules customer workloads onto a distributed fleet; and growth engineering, from programmatic SEO to automated outreach and conversion experiments.Skills and qualifications2+ years with TypeScript / React / Node.js, professional or serious personal projectsAdvanced Linux and command line, you are comfortable living in a terminalComfortable with databases and caching (bonus: DynamoDB, Redis)Hands-on with DockerAble to ship, test, and own production code end to endExperience in a real codebase, not just tutorialsWorking English, written and spokenNice to have: Go, AWS, Terraform, Kubernetes, bare metal or GPU infrastructure, networking, CI/CD, technical SEO, cold email at volume, paid acquisition.The videoRequired, five minutes or less, in English.

Two parts: your face on camera introducing yourself, and a screen recording that demos your best work, the users you got on it, and the hardest problems you solved.
