Wireless Network R&D / Software Engineer

About the role

The company is looking for a Wireless Network R&D / Software Engineer to design, develop, test and improve mobile core network software for Private Mobile Networks. The role contributes to 3GPP-compliant mobile core functions, turning telecom specifications into maintainable, reliable and production-ready software. It combines software engineering, protocol research, cloud-based test environments, interoperability testing, fault analysis and technical documentation.

Key responsibilities

• Design and implement mobile core network functions in Go, with opportunities to use Rust, and turn 3GPP specifications into software and test requirements.
• Work with mobile core protocols and interfaces such as S1AP, PFCP, GTP, Diameter, RTP and SIP, applying Linux and IP networking knowledge to development, integration and troubleshooting.
• Analyse network behaviour using logs, packet captures and tools such as Wireshark.
• Perform unit, integration, interoperability and load testing, build cloud-based test environments on GCP and validate under realistic conditions.
• Investigate and resolve defects through systematic fault analysis and quality improvement.
• Use Docker and Git-based team practices, including code and design reviews, and contribute to cloud-native development with opportunities for Kubernetes.
• Write technical documentation and collaborate with engineers, researchers, product stakeholders and partners.

Required profile

• Bachelor's or Master's degree in Computer Science, Computer Engineering, Electrical Engineering, Telecommunications, Information Technology or a related field.
• Experience developing commercial software and implementing software in Go.
• Basic knowledge of Linux and IP networking, and of virtualisation technologies such as Docker.
• Knowledge of cloud computing and cloud-based development or testing environments.
• Team development experience with Git.
• Strong logical problem analysis, technical communication and collaboration skills.

Required skills

• Go, Rust, unit testing, code reviews and design reviews.
• 3GPP specifications, EPC, IMS, 5GC, S1AP, PFCP, GTP, Diameter, RTP, SIP.
• Linux, IP networking, GCP, Docker, Kubernetes, cloud-native development.
• Integration, interoperability and load testing, Wireshark, defect analysis.

Preferred qualifications include Rust experience, EPC/IMS/5GC experience, 3GPP-referenced design, Wireshark fault analysis, Kubernetes and cloud-native development experience. Expected outcomes: understand the environment within 2 months, develop features independently within 6 months, and lead quality improvements within 12 months.
