Senior Product Cybersecurity Engineer – Secure Product Architecture

Job Description

The Role

The Senior Product Cybersecurity Engineer role sits within the broader Product Cybersecurity organization at General Motors and focuses on protecting in-vehicle systems, their trust boundaries, and access to vehicle functions. This engineer acts as a security design owner for in-vehicle security, including gateway security as well as secure diagnostics, unlock, and firewall capabilities, across current and next-generation software-defined vehicle platforms.

What You’ll Do

• Own and evolve the security design for secure diagnostics, secure unlock, in-vehicle private networks, gateways, and firewall capabilities.
• Translate threat assessments and architectural decisions into clear, testable security requirements for vehicle systems, platforms, and supplier-delivered components.
• Define and maintain security policies that control diagnostic access, communication paths, trust boundaries, and traffic between in-vehicle domains.
• Develop, maintain, and mature in-vehicle firewall and gateway policies as vehicle architectures, services, and delivery requirements evolve.
• Partner with engineering, architecture, validation, service, and supplier teams to ensure security controls and policies are implemented correctly.
• Lead and support security design, policy, and implementation reviews across internal teams and suppliers.
• Identify gaps, assess risk, and drive practical improvements to diagnostic access, secure unlock, gateway security, and firewall policy enforcement.
• Keep security requirements, design decisions, and policy artifacts current with software-defined vehicle delivery timelines and platform changes.
• Serve as a subject-matter expert for secure diagnostics and in-vehicle security, and build self-service references that help the broader team scale.

Your Skills & Abilities (Required Qualifications)

• 6+ years of experience in product, embedded, vehicle, or automotive cybersecurity, with hands-on ownership of security design, requirements, or policy development.
• Strong working knowledge of secure diagnostics, secure vehicle access, in-vehicle security, gateways, and firewalls.
• Solid understanding of embedded security principles, including authentication, authorization, access control, secure communication, and protection of sensitive vehicle functions.
• Experience translating threat assessments and architectural decisions into technical security requirements and policies for internal engineering teams and suppliers.
• Experience owning or maintaining security policies and requirements across the development lifecycle.
• Demonstrated ability to lead security design and implementation reviews and align stakeholders across engineering, validation, service, architecture, and supplier teams.
• Strong communication and technical documentation skills, with the ability to explain complex security concepts to both cybersecurity and non-cybersecurity audiences.
• Bachelor’s or master’s degree in Computer Science, Computer Engineering, Electrical Engineering, Cybersecurity, or equivalent practical experience.

What Will Give You A Competitive Edge (Preferred Qualifications)

• Experience with software-defined vehicle architectures and evolving in-vehicle system designs.
• Experience working across supplier-delivered electronic control units, gateways, firewall platforms, diagnostic systems, and secure firmware ecosystems.
• Experience defining or managing firewall policies, gateway security policies, and communication security requirements.
• Prior embedded development, systems engineering, or vehicle engineering experience.
• Prior role or experience in the automotive industry or a similarly complex, deadline-driven, and regulated field.
• Familiarity with threat assessment processes and translating threat outputs into security requirements, implementation guidance, and validation objectives.
• Experience balancing security rigor with platform capability, supplier constraints, and vehicle program timing.

What You’ll Bring

• Deep ownership instinct — you drive requirements, policy gaps, and blocked items to closure rather than waiting for others.
• A pragmatic approach that balances security rigor against real platform capability, supplier readiness, and vehicle program timing.
• Clear technical judgment on risk, access control, trust boundaries, and how security requirements should be specified and implemented.
• Strong communication skills and a habit of packaging knowledge so teams can scale without depending on a single expert.
• A collaborative mindset that helps engineering and supplier teams build secure vehicle capabilities early rather than reviewing from the outside.
• Curiosity and adaptability as vehicle architectures, services, and cybersecurity expectations continue to evolve.
