Who we are

⚡️ About Nomos

We help hardware companies launch their own electricity plans by abstracting all legal and operational complexity of an electricity retailer into a simple API layer. One year in, Europe’s leading solar and heat pump retailers are building their energy plan on Nomos.
Nomos focuses on making energy cheaper for 200 million European households. We achieve this by developing new energy products and offering them as embedded features for Europe’s leading technology companies (e.g. EnergyTechs, EV manufactures and heat pump installers).
We transform businesses into full-service energy providers and offer consumers cost saving and convenient energy plans. Have a look at our website and our API documentation to learn more.

🏄‍♂️ About the team

We raised capital from tier-1 investors, including the founders of Forto, Soundcloud, Dance, Swan, Polarstern Energie, Enode and more.
You will join a lean, talent-dense team and work directly with Nils (CTO). Started by Stefan (CEO) and Nils in 2024, the Nomos team now consists of former researchers, founders and senior engineers united by a deep frustration of the current energy system and the vision to build a category leading enterprise out of Europe.
We work in a beautiful office in Berlin-Mitte. We strive to build a strong culture of effective communication, ownership and belonging. In this critical phase of our venture this translates to working in-person in Berlin with a truly exceptional group of hackers and painters.

What you’ll do

Nomos is building the core infrastructure for dynamic electricity plans. To make this possible, we’ve developed our own operating system, spanning a modular billing engine, low-level energy-market communication protocols, and a full accounting ledger. Your responsibility will include:
Solve for complexity through design. The energy market is full of edge cases, legacy protocols, and evolving regulations. Your job is to turn that chaos into clear, elegant abstractions and design APIs and systems that make something deeply complex feel simple and reliable.
Scale the core. You’ll work on the beating heart of Nomos: our billing engine, data pipelines, and partner integrations. You’ll design for performance, correctness, and resilience — building systems that can scale 10× without breaking.
Bias for action. We optimize for momentum. You’ll have full autonomy to ship, refactor, and push ideas forward without waiting on layers of approval — the shortest path from idea to production is the right one.
Raise the bar. You’ll shape our engineering standards, review critical code, and contribute to the technical culture of a team that values clarity, pragmatism, and velocity.

👩‍💻 Stack - Typescript in the front and back

You should be familiar with Typescript based full-stack applications. We value high learning velocity, so we trust that you can pick up a new language/framework quickly if you're currently working with a different stack.
Frontend: Next.js (React), Typescript, Tailwind, shadcn
Backend: Temporal, Hono, Postgres, Drizzle (ORM), Fragment, Stripe

You have 3+ years of experience building reliable backend infrastructure
You are excited about solving complex engineering challenges in the energy space
You are driven by nonconformist curiosity and have shown this in your career or side projects - we’re excited to hear about these!
