Embedded Software Engineer (C++/Linux/Qualcomm)

About the Role

We are seeking a hands-on Embedded Software Engineer to implement advanced algorithms on vehicle cellular communication modules. In this role, you will work extensively with C++ (preferred), Linux (Yocto), and Qualcomm controllers. You will be responsible for reading large volumes of source code, writing moderate amounts of production code, and conducting in-vehicle algorithm tests. While the algorithms will be designed by GM, you will be expected to develop them robustly using C++ on Linux.

Key Responsibilities

• Implement uplink and downlink outage detection algorithms on vehicle cellular modules.
• Design & develop advanced 5G link diagnostics mechanisms using inputs across multiple layers of the 5G communication stack.
• Accurately detect 5G link issues and classify root causes across the end-to-end communication chain.
• Identify, expose, and utilize low-level cellular metrics by modifying cellular module source code.
• Produce clear diagnostic reports explaining issue causes and potential resolutions.
• Perform extensive in-vehicle algorithm testing and validation.

Required Technical Skills

Programming & OS:

• Strong proficiency in C/C++ (C++ preferred) and Python.
• Deep experience with Linux-based embedded environments (specifically Yocto).

Cellular & Networking:

• Deep understanding of:
  • 5G cellular architecture
  • TCP/IP networking
  • Cross-layer network diagnostics
• Hands-on experience with Cellular communication modules (e.g., Qualcomm platforms, specifically 525M or similar controllers).
• Cellular know-how is required – even without direct hands-on experience, you must understand the theory and stack.

Debugging & Development:

• Ability to analyze and modify low-level source code (significant source code reading; moderate writing).
• Strong debugging, testing, and validation skills.
• Knowledge of Wi-Fi systems and device connectivity behavior is a plus.

Preferred Background

• 5+ years of relevant hands-on experience (MS or BS degree).
• Experience with in-vehicle or automotive communication systems.
• Comfortable working with pre-existing algorithm designs (provided by GM) and implementing them in production-grade C++.
