Senior Embedded 5GC Software Development Engineer

Job description

We are seeking a Senior Embedded 5GC Software Development Engineer to drive innovation in 5G Core network functions. In this role, you will design and implement high-performance, 3GPP-compliant control-plane and user-plane functionality, focusing on ARM-based architectures. Your expertise will contribute to building robust, carrier-grade systems, ensuring optimal performance and reliability.

Responsibilities

Develop embedded software for 5G Core network functions, including AMF, SMF, UPF, AUSF, UDM, PCF, and NRF. Implement and maintain 5G protocols and procedures, such as NAS, NGAP, PFCP, and GTP-U. Design and develop high-performance software using C, Go, and Rust. Optimize software for Linux embedded systems on ARM-based platforms. Create high-performance packet-processing components with DPDK. Enhance system performance for latency, throughput, CPU usage, and memory efficiency.

Debug complex protocol, system, and performance issues using advanced tools. Collaborate with cross-functional teams to ensure seamless integration. Stay updated with the latest 5G Core technologies and industry trends.

Qualifications

Extensive experience in 5G Core architecture and call flows. In-depth knowledge of 3GPP procedures, including registration, mobility, and session management. Strong programming skills in C, with experience in Go or Rust. Proficiency in Linux system programming and embedded Linux development. Experience with ARM-based systems and multi-threaded programming. Solid understanding of networking fundamentals (TCP/IP, UDP, SCTP, HTTP/2).

Expertise in packet processing and performance tuning. Familiarity with DPDK and its applications.

Preferred

Experience in implementing 5G Core network functions in production. Strong debugging skills using tools like Wireshark, GDB, and tcpdump.
