Job Summary
In this role, you will develop cloud-native 5G Standalone core components, overseeing the design and implementation of network functions while troubleshooting complex telecommunications issues in real time.
Job Technologies
Your role in the team
- 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 / Principal 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.
- 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 across regions.
- You'll set technical direction and raise engineering standards across teams - mentoring engineers, reviewing designs, and driving decisions on protocols, network functions, and core architecture.
- You'll troubleshoot complex, live telecommunications issues across the stack, from core network protocols down to the running service.
