Job description

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

• C, C++
• Secure boot, root of trust, chain of trust, trusted execution environments
• Device identity, hardware-backed security
• Cryptography, authentication protocols, key management, secure provisioning, secure communications
• IoT, wireless technologies, cellular platforms, telecommunications equipment
• Bootloaders, embedded Linux, operating system startup processes, platform initialization
• Microcontrollers, SoCs, embedded processors, embedded software, firmware

Compensation: $75.00–$85.00 per hour (depends on experience level)
