About the role
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.
What you will do:
•
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.
