Your Role As an Engineering Manager, you will lead a cross-functional team of 10 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.
