About this role
ABOUT THE ROLE
This is a Backend Engineer role on the core infrastructure team at a pre-seed energy technology startup building the operating layer for next-generation dynamic electricity plans. You will help design and scale a modular billing engine, low-level energy-market communication protocols, and a full accounting ledger, foundational systems that power how energy is priced, delivered, and billed.
WHAT YOU'LL DO
- Design for complexity: architect scalable, maintainable backend systems that handle real-world energy billing and market data challenges.
- Scale the core: build and improve the infrastructure underpinning dynamic electricity plans and reliable billing flows.
- Ship with ownership: take features from design through production with a bias for action and a high bar for quality.
- Raise standards: contribute to engineering culture, code quality, and technical decision-making as an early team member.
WHAT WE'RE LOOKING FOR
- At least 3 years of experience building reliable backend infrastructure in production environments.
- Proficiency in TypeScript and Node.js, including strong command of asynchronous programming patterns.
- Experience with PostgreSQL and ORM-based data access (Drizzle or similar).
- Hands-on experience with Next.js backend services, including API routes or server components.
- Familiarity with distributed systems concepts and designing scalable, maintainable core services.
- Experience integrating Stripe payments and billing flows is a plus.
- Strong computer science fundamentals through a formal degree or equivalent practical experience.
- A track record of technical exceptionality: standout projects, competition results, research, founding experience, or comparable evidence.
- Experience in an early-stage startup environment, or demonstrated genuine interest in that context.
- Background in application-centric product or infrastructure work rather than narrowly specialized domains such as data pipelines or AI infrastructure.
- Fluency in German at C1 level or above.
- Currently working as a hands-on individual contributor with recent production coding and shipping experience.
COMPENSATION & BENEFITS
- Salary: EUR 80,000 to EUR 120,000 per year.
- Visa sponsorship is available.
LOCATION
On-site in Berlin, Germany, five days per week.

Published on Ashby under the board identifier Clera, which is the name the employer’s own job board carries. RoleSprint has not verified the company’s registered or trading name, so it is shown exactly as published rather than tidied up.
RoleSprint is not the employer and not a recruiter. Applications are made on the employer’s own site and never reach us; what RoleSprint does is help you decide whether a role is worth your time and prepare for it if it is.
