Job Title: Senior 5G RAN Architect (Remote)

Location: Fully Remote

Working Model: Remote

About the Role

We’re looking for an experienced Senior 5G RAN Architect to play a pivotal role in shaping next-generation radio access technologies. You’ll work at the heart of our product development lifecycle—driving architecture, design, verification, and performance optimisation across 5G NR protocol software. This is a high-impact role for someone who thrives on solving complex technical challenges and influencing product direction in a fast-moving, global environment.

Key Responsibilities

• Lead product development activities including HLD, LLD, feature design, implementation, and verification for 5G NR protocol software.


• Analyse 3GPP features and drive development across multiple subsystems, ensuring robust testing and high-quality delivery.


• Provide expert guidance on intricate design issues and architectural decisions.


• Continuously improve system performance through optimisation and high-quality engineering practices.


• Design, validate, and implement advanced 5G architecture components such as Carrier Aggregation, Network Slicing, and Scheduling.


• Collaborate with cross-functional teams to integrate new features and emerging technologies.


• Drive innovation by exploring new programming paradigms and modern software architectures.


• Ensure system reliability and scalability through rigorous testing, documentation, and best-practice engineering.


• Develop architectural standards, guidelines, and frameworks to support consistency across projects.


• Partner closely with product management to align roadmap priorities with customer needs and market trends.

Your Profile

• 10+ years in RAN design, optimisation, and troubleshooting, including 5+ years working directly with 5G/LTE technologies.


• Deep understanding of 4G LTE and 5G NR, including radio interface protocols, PHY/MAC layers, and eNB/gNB configurations.


• Strong hands-on programming experience in C, C++, Linux (async/sync multithreaded code), Windows, and performance optimisation.


• Proven ability to debug complex gNodeB issues, including log analysis and troubleshooting.


• Familiarity with key layers/sublayers such as MAC, RLC, PDCP, Scheduler, Power Control, Link Adaptation, GTP-C, GTP-U.


• Experience with CI/CD tools including Jenkins and Git.


• Analytical mindset with strong problem-solving skills.


• Excellent communication skills and ability to work effectively in an international, cross-functional team.

Why Join Us?

• Work remotely while contributing to cutting-edge 5G innovation.


• Influence architectural decisions and shape next-generation RAN technologies.


• Collaborate with world-class engineers in a global environment.


• Be part of a team that values technical excellence, innovation, and continuous improvement.
