## Job description

### ABOUT THE ROLE

Join the core infrastructure team at an early-stage energy technology company, building the backend systems behind dynamic electricity plans and reliable billing. You will help develop scalable services for billing and energy-market communication.

### WHAT YOU'LL DO

- Design backend systems that reduce complexity in billing and energy-market workflows.

- Scale core infrastructure to support growing transaction volumes and market demands.

- Ship features and improvements through rapid iteration and practical engineering decisions.

- Raise technical standards through code reviews, architecture decisions, and mentorship.

### WHAT WE'RE LOOKING FOR

- At least 3 years of hands-on experience building and shipping reliable backend systems in production.

- Strong TypeScript and Node.js skills, including asynchronous programming.

- Experience with PostgreSQL and ORM-based data access, such as Drizzle or similar tools.

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

- Familiarity with distributed systems and designing scalable, maintainable services.

- Experience integrating Stripe payments and billing workflows.

- Strong computer science fundamentals through formal education or equivalent practical experience.

- Fluent or native-level German proficiency, C1 or higher.

- Interest in early-stage environments, an ownership mindset, and evidence of strong technical ability through projects, research, competition, or founding work.

- Broad application-building experience and clear written and verbal communication skills.

### COMPENSATION & BENEFITS

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

### LOCATION

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

**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.
