Backend Engineer

About the Role

Join a fast-moving energy technology company building the operating system for the next generation of energy in Europe. This role sits on the core infrastructure team , where you'll architect and scale systems that power modular billing engines, low-level energy-market communication protocols, and full accounting ledgers. If you're energised by deep technical complexity and want your work to have a direct impact on European households and energy markets, this is the role for you.

What You'll Do

• Solve for complexity through design — tackle hard architectural problems and design systems that remain clean and maintainable as they scale.

• Scale the core — build and evolve the backbone infrastructure that supports dynamic electricity plans and reliable billing at scale.

• Bias for action — ship with speed and confidence; move projects forward decisively in an ambiguous, fast-paced environment.

• Raise the bar — champion engineering excellence through code reviews, technical discussions, and leading by example.

What We're Looking For

Must-have:

• Proficiency in backend development using TypeScript (Node.js) with a strong grasp of asynchronous programming — this is a dealbreaker requirement.

• Hands-on experience with PostgreSQL and at least one ORM (Drizzle preferred) for data access.

• Experience with Next.js , including API routes or server components for backend services.

• Familiarity with distributed systems concepts and designing scalable, maintainable core services.

• C1+ English language proficiency (written and verbal).

Nice to have:

• Experience integrating Stripe payments and related billing flows.

• Exposure to the broader stack: Temporal, Hono, Tailwind, Fragment.

• Strong CS fundamentals — formal degree or equivalent practical experience.

• Ownership mindset with strong written and verbal communication skills.

Tech Stack

• Languages & Frameworks: TypeScript, Node.js, Next.js, Hono

• Database: PostgreSQL, Drizzle ORM

• Infrastructure & Tooling: Temporal, Stripe, Fragment

• Frontend: Tailwind CSS

Compensation & Benefits

• Salary: $80,000 – $120,000 per year (USD equivalent)

• Visa sponsorship: Available

• Opportunity to work at the forefront of European energy markets with a high-ownership, low-bureaucracy team
