Senior Platform Security Engineer

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.

What you’ll do

• 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

What you bring

• 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 , or other low-level systems near the hardware layer
• Deep understanding of secure boot , root of trust , chain of trust , trusted execution environments , device identity , and hardware-backed security concepts
• Proficiency in C and C++
• Experience with microcontrollers, SoCs, embedded processors , or security-focused hardware architectures
• Knowledge of cryptography , authentication protocols , key management , secure provisioning , and secure communications
• Experience designing security solutions for automotive systems , connected devices, IoT products , wireless technologies, cellular platforms, or telecommunications equipment
• Familiarity with bootloaders , firmware architecture , embedded Linux , operating system startup processes, and platform initialization
• Ability to think like an attacker to identify how physical or logical access systems could be bypassed, cloned, spoofed, or manipulated
• Experience performing technical research, building prototypes, and translating new ideas into deployable, scalable solutions

Tools and focus areas
