We are an in‑office company, and our expectation is that employees primarily work from their Applied Intuition office 5 days a week. However, we also recognize the importance of flexibility and trust our employees to manage their schedules responsibly. This may include occasional remote work, starting the day with morning meetings from home before heading to the office, or leaving earlier when needed to accommodate family commitments.

As a Security Architect at Applied Intuition, you will lead the design and implementation of cybersecurity architectures for next‑generation automotive systems, ensuring compliance with ISO/SAE 21434 cybersecurity engineering standards and UN Regulations 155/156 requirements. Working alongside embedded and application security engineers, you will establish security controls spanning silicon hardware, embedded systems, POSIX system, networks, and cloud infrastructure for automotive platforms. This role requires deep technical expertise in automotive cybersecurity frameworks, hands‑on experience with secure development lifecycle (SDL) processes, and the ability to translate regulatory requirements into implementable security architectures.

• Develop cybersecurity architectures compliant with ISO/SAE 21434 engineering requirements and UN R155 Cybersecurity Management System (CSMS) mandates across all vehicle lifecycle phases (concept, development, production, operation, decommissioning)
• Implement UN R156‑compliant Software Update Management Systems (SUMS) with secure OTA update mechanisms, cryptographic verification, and version control for automotive ECUs
• Conduct threat analysis and risk assessments (TARA) per ISO 21434 Annex C requirements, addressing 69 attack vectors identified in UN R155 Annex 5
• Design hardware‑rooted security controls for automotive SoCs including secure boot, hardware security modules (HSM), and TEE implementations
• Collaborate with suppliers to ensure Tier 1/Tier 2 component security meets ISO 21434 supply‑chain requirements and UN R155 post‑production obligations
• Develop automotive‑specific security requirements for AI/ML systems in autonomous driving platforms, addressing model integrity and adversarial attack prevention

• 7+ years of hands‑on experience designing and deploying security solutions for embedded automotive systems, with proven expertise in:
  • Automotive communication protocol security (CAN bus hardening, Ethernet intrusion detection)
  • Cryptographic engineering for resource‑constrained environments (ECC optimization, post‑quantum crypto prototyping)
• Proficiency in automotive security tool chains:
  • Embedded debug tools (JTAG, UART, Trace
    32)
  • Vehicle network analysis (Vector CANoe, Wireshark dissectors for SOME/IP)
  • ECU flashing and diagnostic tools (ODX/PDX scripting, UDS exploit development)
• Strong systems programming skills in C/C++/Rust for bare‑metal and RTOS environments, with experience in:
  • Secure over‑the‑air update implementations
  • Real‑time intrusion detection systems for vehicle networks
• Demonstrated ability to lead technical security initiatives, including:
  • Threat modeling for complex automotive architectures
  • Security code reviews for safety‑critical embedded software
  • Mentoring junior engineers in secure coding practices
• Familiarity…
