About the Role
Join a fast-moving energy technology company building the operating system for the next generation of electricity supply in Europe. The engineering team is developing a modular billing engine, low-level energy-market communication protocols, and a full accounting ledger — powering dynamic electricity plans for households and hardware manufacturers across the continent.
As a Backend Engineer on the core infrastructure team, you'll work on the systems that sit at the heart of the platform: scalable, reliable, and designed to handle the complexity of real-time energy markets, embedded billing, and regulated electricity supply.
What You'll Do
-
Solve for complexity through design — translate ambiguous, multi-layered business and regulatory requirements into clean, maintainable backend architecture.
-
Scale the core — own and evolve the critical services underpinning billing, ledger, and market communication systems as the platform grows.
-
Bias for action — ship with speed and confidence; make pragmatic trade-offs and iterate quickly in a fast-paced environment.
-
Raise the bar — champion engineering best practices, participate actively in code review, and help grow the technical culture of a small but high-calibre team.
What We're Looking For
Required
-
Bachelor's degree in Computer Science or equivalent practical experience.
-
3–10+ years of backend development experience.

Strong proficiency in TypeScript (Node.js), including a solid grasp of asynchronous programming patterns.
-
Production experience with PostgreSQL and an ORM (e.g. Drizzle) for data access and schema management.
-
Experience with Next.js, including API routes or server components used for backend services.
-
Familiarity with distributed systems concepts — designing scalable, maintainable core services.
-
Experience integrating Stripe payments and related billing flows.
-
Strong written and verbal communication skills, an ownership mindset, and the ability to operate effectively in a fast-paced, ambiguous environment.
-
Willingness to work on-site in Berlin, Germany.
Nice to Have
-
Familiarity with workflow orchestration tools (e.g. Temporal).
-
Experience in energy, fintech, or other regulated / billing-heavy domains.
-
Exposure to API-first or headless platform architecture.
Tech Stack

Compensation & Benefits
-
Salary: €80,000 – €120,000 per year, depending on experience.

Opportunity to join a small, high-impact team at an early stage and shape core technical decisions from the ground up.
