• Develop and maintain secure embedded Linux and RTOS environments across control modules for propulsion, chassis, and body systems.
• Design and integrate mechanisms for:
  • Secure boot and firmware integrity verification
  • Cryptographic key management and hardware security modules (HSMs)
  • Secure OTA (over‑the‑air) updates and signed software deployment
  • Encrypted and authenticated vehicle communications (CAN, CAN FD, Automotive Ethernet)
  • Trusted execution environments (ARM Trust Zone, TPMs)
• Participate in threat modeling, secure code reviews, and vulnerability assessments.
• Support compliance with emerging vehicle security standards (ISO/SAE 21434, UNECE WP.29 R155/R156).
• Contribute to system‑level design decisions that strengthen the vehicle’s overall security architecture.

• Bachelor’s or Master’s degree in Computer Engineering, Electrical Engineering, Computer Science, or a related field.

  • Linux kernel or driver development
  • Platform firmware (U‑Boot, EDK2)
  • Trusted OS development (OP‑TEE, Trusty)
  • Security co‑processor or TPM firmware
• Familiarity with ARM‑based SoCs used in automotive or industrial applications (e.g., NXP, Renesas, NVIDIA Jetson, TI).
• Working knowledge of vehicle communication protocols (CAN, LIN, Automotive Ethernet).
• Must be a U.S. Person due to access to export‑controlled technology.

• Experience implementing security features in automotive or commercial EV platforms, especially medium‑duty trucks or chassis control systems.
• Familiarity with drive‑by‑wire architectures, domain controllers, or electrified chassis systems.
• Knowledge of AUTOSAR Security, secure diagnostics (UDS), or secure update frameworks.
• Understanding of functional safety (ISO 26262) and its relationship to security.
• Experience with cryptography, PKI, or secure manufacturing and provisioning processes for embedded ECUs.

• Comprehensive Health, Dental & Vision (HDV) – 100% employee covered
• Early‑stage Stock Options
• Robust Retirement Savings (401(k), HSA, FSA)
• Generous Paid Time Off (PTO) & Parental Leave
• Annual Vacation Bonus
