• Work with hardware engineering teams so findings are prioritized, validated, and remediated
• Identify and assess hardware security risks across the product lifecycle covering designing, manufacturing, deployment, updating, and decommissioning
• Lead hardware security architecture reviews, perform threat modeling, and run security testing for product systems
• Define and review security requirements for hardware platforms and embedded systems, including firmware interfaces, boot processes, debug capabilities, and device lifecycle controls for cloud-connected environments
• Drive end-to-end security for device hardware across both IoT and cloud security infrastructure

What you bring

• 5+ years of experience in Hardware Security, including creating security-by-design patterns for new devices and platforms
• 5+ years of experience partnering with product teams to create security designs and provide security requirements
• 5+ years hands-on development experience using Python and C/C++
• Strong understanding of hardware root of trust, secure boot, attestation, key protection, device identity, and secure provisioning
