Secure Software Developer Jobs in Detroit, MI (NOW HIRING)

Job Description
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.
