Embedded Engineer, Vehicle Security

About the Team

At Harbinger Motors, we’re building the next generation of electric medium-duty trucks and chassis systems. Our clean-sheet platform combines advanced embedded control, drive-by-wire, and electrified powertrain technologies to deliver a safer, smarter, and more efficient vehicle foundation.

As part of the Software team, you’ll focus on securing the embedded systems that power Harbinger’s vehicles. From bootloaders and firmware to in-vehicle networks and update mechanisms, you’ll help ensure that our software is resilient against cyber threats and built with safety and trust at its core.

What You’ll Do

• Collaborate with software and hardware teams to design and implement security-critical features for embedded controllers and vehicle networks.
  
  
• 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 TrustZone, 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.
  
  

Required Qualifications

• Bachelor’s or Master’s degree in Computer Engineering, Electrical Engineering, Computer Science, or a related field.
  
  
• 3+ years of experience developing and securing embedded systems (Linux or RTOS).
  
  
• Strong proficiency in C++, C and/or Rust for low-level software development.
  
  
• Experience in at least one of the following:
  
  
• 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.
  
  

Preferred Qualifications

• 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.
