About the Role
Join the core infrastructure team of a fast-growing energy technology company building the operating system for the next generation of European energy. The platform combines a modular billing engine, low-level energy-market communication protocols, and a full accounting ledger — delivered as a headless, API-first layer that enables hardware companies and energy providers to launch dynamic electricity plans rapidly.
As a Backend Engineer, you will work across highly complex, distributed systems that power real-time electricity pricing, billing, and market integrations. This is a high-ownership role for engineers who love designing for scale and operating with autonomy in a fast-moving environment.
What You'll Do
- Solve for complexity through design — Architect clean, maintainable solutions to inherently hard infrastructure problems in energy billing and market communication.
- Scale the core — Contribute to scalable, reliable backend services that handle dynamic pricing, billing flows, and ledger operations at volume.
- Bias for action — Move quickly and decisively; ship meaningful work and iterate with purpose.
- Raise the bar — Uphold and improve engineering standards through code review, documentation, and thoughtful system design.
What We're Looking For
Required:
- Bachelor's degree in Computer Science or equivalent practical experience
- 3–10+ years of backend engineering experience
- Proficiency in TypeScript (Node.js) with a strong grasp of asynchronous programming
- Hands-on experience with PostgreSQL and an ORM (experience with Drizzle is a plus)
- Experience with Next.js, including API routes or server components used for backend services
- Familiarity with distributed systems concepts and designing scalable, maintainable core services
- Experience integrating Stripe payments and related billing flows
- Strong written and verbal communication skills in English
- Ownership mindset and 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 with lightweight HTTP frameworks (e.g., Hono)
- Background in energy, utilities, fintech, or similarly regulated/complex domains
Tech Stack
- Languages & Frameworks: TypeScript, Node.js, Next.js, Hono
- Database: PostgreSQL, Drizzle ORM
