Are you an engineer at heart, driven by solid engineering practices and real-world impact? Do you have experience in telco or networking and want to modernize how connectivity is built?
At emnify, we are evolving the foundations of our global IoT connectivity platform, and we’re looking for a Staff Software Engineer to help lead that transformation.
You’ll join our Core Network team, a cross-functional group of 9 engineers responsible for the systems that power authentication, signalling, and messaging across our infrastructure. These systems are stable and in production, but we’re actively moving from legacy components to scalable, cloud-native services.
You’ll work with a diverse and evolving tech stack, including:
- C++ and Erlang for SS7, SIGTRAN, and DIAMETER signalling routing
- ElastiCache Redis, DynamoDB, and Aurora MySQL as data stores
- An AWS environment, primarily EC2 and EKS, with connectivity through Direct Connect
- AWS MSK and gRPC for inter-service communication
This position can be based in emnify’s office in Berlin or Würzburg, or remote within Germany or Poland. While we offer flexibility, the team values in-person collaboration. Most members currently choose to come to the office several days a week.

- Prioritize work based on engineering impact, using metrics to guide decisions
- Technical Competency: Hands-on experience with C++ and Erlang, along with AWS services (especially EC2 and EKS); working knowledge of Kafka and Linux
- Domain Proficiency: Solid understanding of IP networks (Layer 3 and 4) and familiarity with telco signalling protocols such as SS7, DIAMETER, SIGTRAN
- Problem-Solving: Solid testing practices and CI/CD mindset; skilled in diagnosing issues in distributed systems
- Effective Communication: Comfortable collaborating across teams and communicating clearly about technical topics
- Adaptability: Capable of navigating legacy systems while driving modern architectural improvements
