Backend Engineer

Job description

### 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 ### Location On-site in **Berlin, Germany**. This role requires regular in-person presence at the Berlin office.
