Lorien is hiring a Senior Platform Security Engineer for an onsite role in Dallas, TX
. This is a contract position (6 months) with the opportunity to extend
. If you want to work on real-world security outcomes, you will research and build next-generation platform protections for connected vehicles
, focusing on low-level hardware and firmware security.

• Research, design, and develop next-generation technologies to strengthen vehicle access security and help prevent theft, unauthorized use, and system compromise
• Build platform trust starting at the lowest levels of the stack, beginning with hardware and firmware
• Lead work from concept and experimentation through prototyping, validation, production implementation, and deployment
• Partner with hardware, embedded software, systems, and product engineering teams to turn security concepts into deployable solutions
• Design and develop secure platform capabilities covering device identity
  , trusted execution
  , authentication
  , cryptography
  , and hardware-backed security
• Investigate emerging attack techniques targeting connected and electronic vehicle systems and develop defenses
• Assess how attackers may bypass, clone, replay, emulate, or manipulate vehicle access technologies and develop countermeasures
• Create proof-of-concept solutions and advanced prototypes that advance automotive security
• Contribute to platform architecture decisions that influence long-term security for future vehicle products
• Address complex technical challenges at the intersection of hardware, firmware, cryptography, and embedded systems

• Bachelor’s degree in computer science or other relevant technical discipline
• 6-8+ years of overall related engineering experience
• Strong background developing firmware, embedded software, platform software
