Jobbeschreibung

Berlin: New Greenfield AI Hub - Senior Full Stack Engineer (Python) ≤ €100k + fast promotion

We're hiring for a Berlin scale-up digitising a traditional, hands-on industry. 900 employees, highly profitable, growing internationally. They built their own software for a sector that still runs on paper and phone calls.

The opportunity

Work at a Berlin scale-up digitising a traditional, hands-on industry. 900 employees, highly profitable and growing. They built their own software for a sector that still runs on paper and phone calls.

The challenge

Complex problems in energy tech, and your job is to turn them into working systems - then bring AI agents to the entire company. On top of that, you'll build a new customer-facing product from scratch.

Why they're hiring now

Software engineering used to be outsourced. They're now building the in-house team from the ground up: 25 people in tech today, with 10 in-house engineers to hire.

Where does AI come in

They want someone to lead LLM work from prototype to production - internal tooling first, customer-facing after. They also pay for whichever AI coding assistant you prefer. Your choice, no committee. Small thing, but it tells you how they think about tooling.

The expectation

You'd own features end to end with a pod around you, and you'd shape the roadmap with Product rather than receive it.

The stack

• Python (FastAPI) or Node.js on the backend
• Vue with TypeScript on the front
• And more..

TDD and clean code are cultural here, not aspirational. You build it, you run it.

What's on offer

• Base salary up to €100k
• A real career path: team lead or engineering manager, a purely technical lead track, or a move into the AI, DevOps or Security teams. Each step carries higher salary and more responsibility so you won't be sitting still for years
• Hybrid, 3 days per week from home possible
• Your own AI coding companion
• 30 days holiday
• Employer pension contribution above the standard rate
• Urban Sports Club, nilo.health, company bike and more
• Work that actually matters
