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.

Responsibilities

  • 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.

Requirements

  • 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 . Candidates must be able to work from the Berlin office.
