Ready to make connectivity from space universally accessible, secure and actionable? Then you’ve come to the right place!
E-Space is bridging Earth and space to enable hyper-scaled deployments of Internet of Things (IoT) solutions and services. We are building a highly-advanced low Earth orbit (LEO) space system that will fundamentally change the design, economics, manufacturing and service delivery associated with traditional satellite and terrestrial IoT systems.
We’re intentional, we’re unapologetically curious and we’re 100% committed to innovate space-based communications and deliver actionable intelligence that will expand global economies, protect space and our planet and enhance our overall quality of life.
We are seeking an experienced Software Engineer with background in 5G Core Network development to join our team. This role focuses on architecting, developing, and maintaining critical network functions and control-plane services that form the backbone of next-generation mobile telecommunications infrastructure. You will apply your expertise in 3GPP protocols, distributed systems, and service-oriented architecture to advance our 5G Core processing solutions while contributing to mission-critical telecommunication systems. This position offers the opportunity to work on high-impact projects that directly support advanced network capabilities and develop innovative solutions that drive the evolution of satellite networks.

What you will do:
-
Design, develop, and maintain 5G Core Network Functions and their associated service-based interfaces (Namf, Nsmf, Nupf, etc.) using modern C++, Python, or equivalent languages on Linux-based systems
-
Develop and implement 3GPP protocols including NAS, PFCP, GTP-U, HTTP/2, and network interfaces such as N4 and N11 to ensure standards compliance and interoperability
-
Develop and maintain 5G core network control-plane probes for real-time monitoring, protocol decoding, signaling extraction, and network traffic analysis
What you bring to this role:
-
Bachelor's degree in a STEM discipline (Computer Science, Computer Engineering, Electrical Engineering, or related field)
-
5+ years of hands-on development experience with 5G Core Network Functions or equivalent LTE/4G EPC (MME, SGW, PGW, HSS) systems
Bonus points for the following:
-
In-depth knowledge of specific 5G network functions: AMF, SMF, UPF, UDM, PCF, AUSF, NRF including behavior, interactions, and call flows
-
Network virtualization and containerization technologies (KVM, VMware, OpenStack, AWS, Kubernetes, Helm, Docker)
Additional RequirementsThis is a fast-paced, high-impact environment - flexibility to occasionally work extended hours or weekends during critical periods is expected.
