The posting

About Us

Founded in Berlin, autarc is a ~75 person start-up who were part of Y Combinator’s S24 batch in San Francisco. Our team consists of people in Sales, Tech and Operations, with the Engineering & Product department currently ~25 people, as we continue to grow throughout the year.

Your Impact

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 as 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

The technologies you will use include:

  • TypeScript, React, Three.js
  • Go, Node/NestJS, Postgres
  • Electric SQL, RxDB, local-first sync patterns
  • Docker, Fly.io, NATS

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

What you bring

  • 2-4 years for Mid-level or 5+ years for Senior of professional software experience
  • Strong React + TypeScript 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)

What we offer

  • 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: MacBook and 27″ monitor.
  • Annual team retreat plus regular team events.
  • Mobility: Dance e-bike or Deutschland-Ticket.
  • Fitness: Urban Sports Club membership.

Next steps

If your application is successful, you will participate in the following:

  • Screening call with Louis (Recruiter)
  • Culture fit call with a Senior Engineer
  • Pair programming/live coding exercise
  • Final on-site interview with Marius (CTO) and the team

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
