Full Stack Engineer

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
