About the role

  • Define and maintain IDS requirements, use cases, and detection objectives across vehicle platforms and network domains.
  • Contribute to the design of in-vehicle IDS architectures, including sensor placement, data collection, and analysis flows.
  • Translate threat models, attack paths, and misuse cases into concrete detection logic, rules, and/or model requirements.
  • Partner with ECU owners, system architects, and suppliers to integrate IDS capabilities into ECUs, gateways, and central compute platforms.
  • Specify and refine IDS interfaces, data formats, and logging requirements for alerts, diagnostics, and backend consumption.
  • Support implementation, integration, and validation activities through lab testing, test vehicle evaluations, and trace analysis.
  • Analyze IDS performance (coverage, fidelity, false positives/negatives) and drive tuning and improvements into the production solution.
  • Ensure IDS design and implementation align with internal cybersecurity processes and external standards/regulations (e.g., ISO/SAE 21434, UN R155).
  • Develop and maintain engineering documentation, including specifications, design descriptions, and test plans.
  • Provide technical guidance and reviews for internal teams and suppliers on IDS-related topics.

Requirements

  • Bachelor’s degree in Computer Engineering, Electrical Engineering, Computer Science, or a related technical field.
  • Solid experience in embedded systems and/or vehicle networking (e.g., CAN, LIN, Automotive Ethernet, SOME/IP, UDS).
  • Strong foundation in cybersecurity principles, including threat modeling, attack surfaces, and defense-in-depth for embedded/vehicle systems.
  • Ability to interpret and apply automotive cybersecurity standards and regulations (e.g., ISO/SAE 21434, UN R155) to engineering designs.
  • Experience with microcontroller-based systems and embedded operating systems, including AUTOSAR architecture and Linux-like environments.
  • Knowledge of software and hardware design.
  • Ability to reconcile future IDS program enhancements with near-term execution to identify design and implementation issues.
  • Proficient in at least one of the following programming languages: C, C++, Python, Go, or Java.
  • Strong analytical, problem-solving, and communication skills, with the ability to clearly document and review technical designs.
  • Ability to handle ambiguity and make decisions and recommendations with limited data.
  • GM does not provide immigration-related sponsorship for this role.
