Senior Backend Engineer, Timetabling

About the role

Aurorabahn Mobility is hiring a backend engineer in Berlin. You will design the data models, services and APIs everything else in the product depends on. The work is judged on whether it stays correct under concurrency, partial failure and three years of requirement changes, not on how quickly the first version shipped.

German engineering hiring rewards depth and patience, and our process reflects that: two technical conversations, no timed puzzle, and a written offer within a week of the last one.

What the work actually looks like

Expect a mix of new services, careful changes to old ones, and migrations on data that cannot be taken offline. You will write the design note before the code for anything substantial, and you will be the person who says out loud that a proposed change makes a guarantee impossible to keep. The team works a hybrid week out of Berlin, usually three days together and the rest wherever you work best.

What we look for

This is a senior individual-contributor role. You will be expected to push back on requirements that do not make sense and to set the technical direction for your part of the product. We are looking for someone fluent in schema design and indexing who thinks about idempotency, transactions and ordering as a matter of habit. Depth in one server language matters more to us than a list of six.

Working at Aurorabahn Mobility

Working time is tracked and respected, overtime is an exception rather than a culture, and German is useful for customer conversations but is not a hiring requirement — engineering runs in English. The range shown is the annual gross salary band for this role.
