The posting

ABOUT THE ROLE

This is a Backend Engineer role on the core infrastructure team at a pre-seed energy technology startup building the operating layer for next-generation dynamic electricity plans. You will help design and scale a modular billing engine, low-level energy-market communication protocols, and a full accounting ledger, foundational systems that power how energy is priced, delivered, and billed.

WHAT YOU'LL DO

- Design for complexity: architect scalable, maintainable backend systems that handle real-world energy billing and market data challenges.

- Scale the core: build and improve the infrastructure underpinning dynamic electricity plans and reliable billing flows.

- Ship with ownership: take features from design through production with a bias for action and a high bar for quality.

- Raise standards: contribute to engineering culture, code quality, and technical decision-making as an early team member.

WHAT WE'RE LOOKING FOR

- At least 3 years of experience building reliable backend infrastructure in production environments.

- Proficiency in TypeScript and Node.js, including strong command of asynchronous programming patterns.

- Experience with PostgreSQL and ORM-based data access (Drizzle or similar).

- Hands-on experience with Next.js backend services, including API routes or server components.

- Familiarity with distributed systems concepts and designing scalable, maintainable core services.

- Experience integrating Stripe payments and billing flows is a plus.

- Strong computer science fundamentals through a formal degree or equivalent practical experience.

- A track record of technical exceptionality: standout projects, competition results, research, founding experience, or comparable evidence.

- Experience in an early-stage startup environment, or demonstrated genuine interest in that context.

- Background in application-centric product or infrastructure work rather than narrowly specialized domains such as data pipelines or AI infrastructure.

- Fluency in German at C1 level or above.

- Currently working as a hands-on individual contributor with recent production coding and shipping experience.

COMPENSATION & BENEFITS

- Salary: EUR 80,000 to EUR 120,000 per year.

- Visa sponsorship is available.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
