Fullstack Engineer; Services

You'll join a new squad focused our fastest-growing product area:
Services. On top of their monthly subscription, our customers can book additional services through autarc — such government subsidy applications (e.g. KfW), energy performance certificates, and more. This area is scaling rapidly and we're hiring dedicated engineering capacity to match.
Your job is to build and ship new services fast. That means new service types, new country rollouts (such as Italy and the UK), and new workflows — often from zero to live in days, not weeks. We expect you to go all-in on AI-assisted development (Claude, Cursor, Copilot) to move at a pace that traditional engineering can't match.
Other things you'll do will include:

• Build and ship end-to-end service workflows
• Expand our service offering into new European markets, adapting to local regulations and requirements
• Ship polished React UIs and interaction-heavy workflows with strong UX
• Integrate AI models (Anthropic, OpenAI) to automate service fulfilment like document generation, form pre-filling, validation
• Build APIs that connect service data across systems and workflows
• Partner closely with Design and Product to deliver features at speed

This is a Fullstack role with a 70/30 split between Frontend and Backend.

• 2-4 years for Mid-level or 5+ years for Senior of professional software experience
• Strong React + Type Script and UX craftsmanship
• Backend experience with APIs, data modelling, and SQL databases
• Comfortable shipping Fullstack features end-to-end
• Already using AI tools (Claude, Cursor, Copilot) in your daily workflow, not just experimenting
• Berlin-based, hybrid 3 days in the office (Mitte)
• Fluent in English (German is a plus)

• Grow with us: As part of a fast-growing, YC-backed climate tech startup with an ambitious team.
• Real ownership: Drive your work from idea to impact.
• Low ego, high trust: No blame, open feedback, collaboration over hierarchy.
• Be part of the energy transition: Help bring more heat pumps and solar to homes every day.
• Hybrid work in Berlin-Mitte: 3 days together in our office near Weinbergspark, 2 from home. Need more flexibility? We'll find a way.
• Modern equipment: Mac Book and 27″ monitor.
• Annual team retreat plus regular team events.
• Mobility: Dance e-bike or Deutschland-Ticket.
• Fitness: Urban Sports Club membership.
