## Job description

### ABOUT THE ROLE

Join a core infrastructure team at an energy technology company building software for dynamic electricity plans. You will develop backend systems for billing, energy-market communications, and accounting, helping make these services reliable and scalable.

### WHAT YOU'LL DO

- Design backend systems that address complex billing and energy-service requirements.

- Build and scale core services that support dynamic electricity plans and reliable billing.

- Develop and maintain backend data access and service logic.

- Contribute hands-on to production code and ship improvements with ownership.

- Help raise the quality and maintainability of core infrastructure.

### WHAT WE'RE LOOKING FOR

- At least 3 years of experience building reliable backend infrastructure.

- Proficiency with TypeScript and Node.js, including asynchronous programming.

- Experience with PostgreSQL and ORM-based data access.

- Experience building backend services with Next.js, including API routes or server components.

- Familiarity with distributed-systems concepts and scalable, maintainable service design.

- Experience integrating Stripe payments and billing flows.

- Strong computer science fundamentals through a degree or equivalent practical experience, plus evidence of exceptional technical work.

- Broad application-building experience and a hands-on record of recent production coding and shipping.

- Fluent German at C1 level or higher, with strong written and verbal communication skills.

### COMPENSATION & BENEFITS

Annual salary range: €80,000 to €120,000. Visa sponsorship is available.

### LOCATION

On-site, five days per week in Berlin, Germany.

**Live in Clera’s hiring system.** Read from the company's own applicant tracking system, not reposted from a job board — so it's a real, open requisition rather than an ad that outlived the role.

We remove it as soon as it disappears at source.
