Backend Engineer

About the Role

This is a backend engineering role on the core infrastructure team of an early-stage energy tech company building the foundational layer for next-generation dynamic electricity plans. You'll work on a modular billing engine, low-level energy-market communication protocols, and a full accounting ledger — systems that need to be both highly reliable and infinitely scalable.

What You'll Do

• Design systems that tame complexity at the architectural level, not just the code level.

• Scale core infrastructure to handle dynamic billing, energy trading integrations, and real-time data flows.

• Take decisive action in ambiguous situations, shipping thoughtful solutions without waiting for perfect information.

• Continuously raise the quality bar across the codebase, technical processes, and team practices.

What We're Looking For

• 3–10+ years of backend development experience with TypeScript (Node.js) and a strong grasp of asynchronous programming.

• Hands-on experience with PostgreSQL and an ORM (e.g. Drizzle) for data access patterns.

• Familiarity with Next.js for backend services — API routes or server components.

• Working knowledge of distributed systems concepts and how to design scalable, maintainable services.

• Experience integrating Stripe payments and building billing flows end-to-end.

• Strong CS fundamentals — formal degree or equivalent practical experience.

• Clear written and verbal communication, an ownership mindset, and comfort operating in a fast-paced, early-stage environment.

Compensation & Benefits

• Salary: €80,000 – €120,000 per year

• Visa sponsorship: Available
