Job description
I'm looking to recruit a Full-Stack Engineer to join a small, senior core team at an early-stage startup reinventing how independent businesses run their operations. This is a rare chance to join at the ground floor: you'll shape product, engineering, and company direction from day one.
What You'll Be Doing:
- Building core systems across ordering, payments, discovery, and workflow automation.
- Working end-to-end across backend, frontend, and infrastructure using Node, Python, React/Next.js, TypeScript, and AWS.
- Designing and evolving intelligent, agentic flows using frameworks such as LangChain, MCP, or similar.
- Deploying, monitoring, and scaling infrastructure in AWS (Terraform, CI/CD).
- Shipping quickly, learning from real user feedback, and iterating rapidly.
- Influencing architecture, technical decisions, and overall engineering standards in a small, high-trust team.
- Collaborating closely with the founding team to move fast, solve meaningful problems, and build elegant, scalable systems.
Requirements
- 3+ years' experience building and shipping production systems (startup or high-growth background strongly preferred).
- Strong full-stack expertise (Node, TypeScript, Python, React/Next.js).
- Solid AWS, Terraform, and CI/CD experience.
- Exposure to agentic or AI-powered systems (e.g., LangChain, MCP).
- Builder mindset with a track record of solving problems and delivering at speed.
- Comfortable operating with autonomy in open, ambiguous problem spaces.
Benefits & conditions
- Competitive salary + meaningful equity.
- Outsized influence over architecture, engineering practices, and company direction.
- Work alongside ambitious, senior builders who care deeply about product quality.
- Backing from top-tier European investors with long-term conviction.
- A startup culture designed for speed, learning, and real product impact - no bureaucracy, just building.
About the company
A well-funded early-stage startup backed by top-tier European investors. They are building an AI-driven commerce platform powered by agentic AI. Helping independent makers and small businesses eliminate the invisible admin that slows them down. Their mission is to create intelligent systems that listen, interpret, and take action so independents can operate with ease, focus, and flow.
