This role operates in a multi-site international engineering environment, at the intersection of standards, algorithms, and real-world systems.

Responsibilities

• Design and implement optimized software aligned with 5G L1 algorithms and protocols
• Develop and enhance UE and base station emulation
• Contribute to pre-6G standards, following 3GPP evolution
• Translate evolving requirements (3GPP releases, operator acceptance needs, O-RAN priorities) into clear software designs, test workflows, and reusable components
• Collaborate with cross-functional experts (systems, RF, protocol, product, customers/partners) to reproduce field issues, debug complex behaviors, and deliver fixes with strong root‑cause discipline

Qualifications

• Strong expertise in 3GPP LTE / NR
• Focus on L1 protocols and Scheduler algorithms
• C / C++
• Real-time programming
• Software development and debugging
• Technical communication in English

Preferred Qualifications

• NVIDIA CUDA GPU programming
• Experience with CI/CD, test frameworks, containers, and/or cloud-based environments
• Experience working in a multi-site environment
