About The Position

The Role GM’s Product Cybersecurity Team safeguards the security and integrity of our vehicle platforms, embedded systems, and connected services across the entire product lifecycle. Our mission is to proactively defend GM products against evolving cyber threats by engineering cybersecurity into every phase — from concept and architecture through development, validation, production, and in-field operation. We seek product cybersecurity professionals with advanced expertise in secure system design, embedded and automotive security, and risk-based threat analysis, capable of driving security-by-design principles, ensuring compliance with global regulations and standards, and strengthening the resilience of GM’s vehicles and mobility ecosystems. We are seeking a Staff Software Engineer to serve as a senior technical authority for Certificate Lifecycle Management (CLM) and vehicle security architecture. In this highly impactful role, you will define and drive secure-by-design architecture for identity, key management, and certificate infrastructure spanning vehicle ECUs, connectivity platforms, and backend systems. This is a deep technical leadership position with broad architectural influence across multiple engineering teams — without direct people management responsibilities. You will directly shape the security foundation of next-generation software-defined vehicles. Your architectural decisions will protect vehicle identity, secure communications, and ensure compliance with global cybersecurity regulations. This is a high-visibility, high-impact opportunity to influence the future of automotive security at scale.
