Jobbeschreibung

Nucleus is a Berlin-based, first‑check deep‑tech fund. We write the first cheque into engineers and scientists building hard things in Programmable Biology, AgriFood, and Neo‑industrials - the companies rebuilding Europe's industrial and biological base from day zero.

We're a small team of engineers, physicists, and bio‑technologists, not ex‑bankers. We obsess over techno‑economics, move fast, and commit deeply. We'd rather ship a rough v1 than admire a perfect spec.

Now we want to turn that same energy on ourselves. We're looking for a solo builder to spend the summer up‑leveling our internal stack - the tooling that decides how fast we can find, judge, and back the next generation of deep‑tech founders. You won't be a junior on an engineering team. You'll own problems end‑to‑end, define your own scope, and ship things the whole partnership uses the next morning.

What you’ll build

Deal‑flow ingestion and enrichment, portfolio dashboards, LLM‑powered research and memo workflows, and the integration plumbing that connects it all. If it removes friction from how a modern fund operates, it’s fair game.

Who we are looking for

• Full‑stack and fast. Comfortable across a modern stack (TypeScript / React / Next.js, Python, Postgres / Supabase) and tooling accelerators like Retool or n8n. You ship end‑to‑end, alone.

• Fluent in plumbing. Most of this job is integration work - Affinity / Attio, Gmail / Calendar, and external data providers. You’ve wrangled messy data and made systems talk to each other before.

• LLM‑native. You build agentic workflows and automations, not just prompt a chatbot. You’ve shipped something real with the frontier APIs.

• High agency, low ego. Strong product sense, genuine business acumen, and the instinct to scope ruthlessly and turn a vague ask into a working tool.

Show us something you’ve shipped. We care far more about a link to a thing you built than a line on your CV.
