About the Role Join a pre-seed-funded energy tech startup that is building the operating system for the next generation of energy. The core infrastructure team is developing a modular billing engine, low-level energy-market communication protocols, and a full accounting ledger — enabling dynamic electricity plans and reliable billing for hardware OEMs, installers, and energy providers across Europe. As a Backend Engineer, you will help shape scalable, maintainable systems at the heart of this platform. What You'll Do Solve complex infrastructure and domain challenges through thoughtful system design. Scale core backend services to support growing energy platform workloads. Move quickly and take ownership — bias for action in a fast-paced, ambiguous environment. Raise the engineering bar through code quality, architecture decisions, and collaborative standards. Build and maintain API routes and server-side services using TypeScript (Node.js) and Next.js. Work with PostgreSQL and Drizzle ORM for reliable, performant data access. Integrate and extend Stripe-based billing and payment flows. What We're Looking For Required: Proficiency in backend development using TypeScript (Node.js) with a strong grasp of asynchronous programming. Required: Experience with PostgreSQL and at least one ORM (Drizzle preferred) for data access. Required: Experience with Next.js, including API routes or server components used for backend services. Required: Familiarity with distributed systems concepts and designing scalable, maintainable core services. Required: C1+ professional language proficiency (English). Experience integrating Stripe payments and related billing flows. Strong written and verbal communication with an ownership mindset. Strong CS fundamentals — formal degree or equivalent practical experience (3–10+ years of relevant backend experience). Tech Stack TypeScript, Node.js, Next.js PostgreSQL, Drizzle ORM Temporal, Hono, Stripe Tailwind (front-end context) Compensation & Benefits Salary range: $80,000 – $120,000 USD annually Visa sponsorship available Location This is an on-site role based in Berlin, Germany .
