Senior PHY Software Engineer – 2G/4G/5G
We are looking for a highly experienced Senior PHY Software Engineer with 10+ years of experience in cellular PHY software development, integration, debugging, and system troubleshooting across 2G, 4G, and 5G technologies.
The role will primarily focus on PHY development, debugging, issue resolution, and integration within our cellular products. As part of our ongoing effort to improve engineering productivity and RCA capabilities, the engineer will also contribute to our AI-assisted development and Root Cause Analysis initiative, helping build and fine-tune AI-based tools/agents for PHY log and crash analysis. The ideal candidate should be a strong PHY domain expert and problem solver, capable of going beyond linear debugging approaches and identifying root causes by correlating evidence across different sources and layers.

What you'll do:
- Design, develop, debug, integrate, and maintain PHY software for cellular communication systems.
- Work across 2G, 4G, and 5G, understanding PHY behavior, implementation,



and interaction with the overall system.
- Analyze complex PHY issues using logs, traces, crash dumps, KPIs, configuration, and system behavior to identify root causes.
- Develop and optimize PHY software and algorithms to improve performance, reliability, and product quality.
- Work with existing codebases and repositories, understand implementation flows, and extend or modify them without destabilizing existing functionality.
- Collaborate with MAC, RLC, RRC, RF, DSP, HW, and system teams to resolve complex product and field issues.

What you should have:
10+ years of experience in wireless communication / PHY software development, integration, debugging, or system troubleshooting.
Strong hands-on experience with 4G/LTE and/or 5G NR PHY, with working knowledge of other cellular RATs such as 2G.
Good understanding of PHY architecture, algorithms, implementation, and interaction with other layers.
