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).

TypeScript, Node.js, Next.js
