Backend Engineer

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

• Payments: Stripe

• Orchestration: Temporal

• Visa sponsorship is available for qualified candidates

• Early-stage equity opportunity at a well-backed pre-seed company
