AI-Driven 4G PHY SW Tech Lead

Posted: 2026-08-16

We are looking for a AI-Driven 4G PHY SW Tech Lead to work on the architecture, implementation, and real-time optimization of the LTE Layer 1 (PHY) software stack. You will be a technical authority for the domain, working across MAC, System, Integration, QA, and Product Management to deliver carrier-grade Open RAN solutions. A core part of the role is advancing how the team applies AI and agentic software development to a large, high-performance codebase, accelerating design, debugging, and delivery.

- Lead the design, development, and evolution of the LTE Layer 1 (PHY) software stack.

- Drive PHY features end to end: architecture, implementation, optimization, testing, and production support.

- Drive performance optimization, debugging, and root cause analysis for carrier-grade real-time reliability.

- Shape the software architecture and technical roadmap of our Open RAN platform.

- Mentor engineers, set the bar for engineering practice, and partner with MAC, System Engineering, Integration, QA, and Product Management.

- Apply agentic software development and LLM-based workflows, and evaluate new tools as they emerge.

What you should have - 3+ years as a Technical Lead or Senior Software Engineer on complex software projects.

- Strong knowledge of the wireless physical layer (PHY), ideally 4G/5G or another OFDM-based technology.

- Hands-on experience with agentic software development and LLM-based workflows, plus a basic understanding of AI internals and RAG.

- Excellent C/C++ and multi-threaded development on Linux-based real-time embedded systems.

- Solid DSP fundamentals, with a track record of optimizing for latency, CPU, and memory.

- Strong debugging and troubleshooting in complex embedded and distributed systems.

- Fluent with Git, CI/CD pipelines, and Agile development practices.

- Strong communicator who can mentor engineers and guide technical decisions across teams.
