Engineering Manager - Core Network (m/f/d)

Your Role 

As an Engineering Manager, you will lead a cross-functional team of 9 engineers (directly and indirectly) responsible for emnify’s mission-critical core network services. These services ensure the connectivity, scalability, and reliability of our global infrastructure, enabling customer devices to connect across 500+ mobile networks worldwide.

This team designs, builds, and operates core components such as HLR/HSS, AuC, Diameter routers, SIGTRAN, SMSC, and other services that power authentication, signaling, and messaging for emnify SIMs globally.

You will play a key role in guiding architecture and engineering practices, helping the team evolve from legacy systems to highly scalable, event-driven, cloud-native solutions, while fostering a high-performance and collaborative culture.

Location: Germany or Poland.
If based in Berlin, we expect you to join us in the office 3 days per week.
If based elsewhere, we ask for monthly travel to our Berlin office.
