Senior Backend Engineer
Acme Robotics · Berlin (hybrid) · €85,000 – €110,000 gross / year
We're a 35-person robotics startup building autonomous warehouse pickers. Our fleet runs across 18 customer sites in Europe and is growing fast — the API that orchestrates it is becoming the centre of gravity for the whole product.
What you'll do
- Own the fleet-orchestration API that hundreds of robots talk to in real time.
- Design and ship a new event-streaming layer to replace our current REST polling — the single biggest reliability project of the year.
- Pair with our two robotics engineers on the data contracts between robot and cloud.
- Mentor two mid-level backend engineers joining in Q3.
What we're looking for
- 5+ years building production backend systems in Python or Go.
- Real experience with event-driven architectures (Kafka, NATS, SNS/SQS, etc.) — not just "I read about it".
- Comfort designing PostgreSQL schemas and writing the kind of SQL that holds up under load.
- A pragmatic sense of when to add abstractions and when to push back.
Nice to have
- Robotics, IoT, or other real-time / hardware-adjacent domain background.
- Open-source contributions we can read.
- German language skills — the team works in English, no German required.
What we offer
- 30 days paid leave + 8 public holidays (we honour Berlin's calendar).
- Berlin office in Friedrichshain, hybrid: 2 days in, 3 from home.
- €1,200 / year learning budget, no questions asked.
- Visa sponsorship if you're outside the EU.
We commit to a 4-stage interview process completed in under 14 days. You will know the salary band before the first call.
