Senior Full Stack Engineer - Remote - Strong TypeScript Experience, Production Experience with LLM Features, AI - Native Workflow
We've partnered with an innovative start-up who believe anyone should be allowed to build software. Years ago the barrier to entry in software development was simple: a laptop and an internet connection - that changed overnight with the advent of AI which has now become essential for competitive software development. However that comes with a cost - often staggeringly so. You could help change that.
We're looking for a senior full-stack engineer with strong backend fundamentals and real experience shipping LLM-powered agentic systems. You will be joining a small team and shaping how the product gets built.
What you will need :
* Strong TypeScript and solid backend fundamentals - data modeling, API design, concurrency, failure modes
* Production experience with LLM features - tool-calling, prompt iteration, streaming, evals, cost and latency tuning
* AI-native workflow - fluent collaborating with coding agents day-to-day (Claude Code, Cursor, etc.)
* Frontend depth
* Linux fundamentals (Bash, Docker, PTYs, networking)
* Sandbox / container orchestration
The Tech Stack :
* Typescript
* Fastify
* PostgreSQL/Prisma
* Redis
* Next.js/React.js
* Anthropic + OpenAI + Gemini + OpenRouter
* Modal/Daytona/E2B sandboxes
* Better Stack
* Github Actions
