Your Role
As part of the larger Engineering department, the Core Network team builds and operates the heart of emnify's SuperNetwork — the mobile core that keeps millions of IoT devices connected across 180+ countries. As we evolve our platform towards a cloud-native **5G Standalone (SA)** core, we're looking for a hands-on 5G SA expert to help us design, build, and run it.
As a Staff engineer with deep 5G SA expertise, you'll take technical ownership of the core network functions and roaming scenarios that make global IoT connectivity work. You'll set the technical direction for our 5G SA core while staying hands-on — designing, implementing, testing, and troubleshooting the software components that run in production at scale. You'll partner closely with engineers across squads, share your expertise, and raise the bar for how we build cloud-native telecommunications software.
This is a hybrid position based at emnify’s Berlin office.
Your Impact
You'll architect, design and build using AI-agentic workflows software components for emnify’s cloud native 5G Standalone core in C++, Go, or Java — implementing and operating network functions (NFs) and the service-based interfaces between them and integrating into the overall emnify platform OSS and BSS.
You'll own 5G roaming scenarios end-to-end, designing and implementing the signaling and interworking that keep IoT devices connected as they move across networks and borders.
You'll help deploy and operate the 5G core at scale on AWS and Kubernetes, building for high availability, observability, and performance a
