Job Description
We are seeking an experienced Principal Firmware Engineer to manage a talented team while remaining a highly hands-on technical contributor. You will lead the design, development, and optimization of highly secure embedded systems. The ideal candidate will have deep expertise in Secure Boot, attestation schemes such as SPDM, secure provisioning, cryptographic firmware signing, and key/certificate revocation mechanisms, alongside strong knowledge of RTOS, Linux kernels, device drivers, and bus protocols. This "player-coach" role requires exceptional problem-solving skills to diagnose and resolve complex hardware-security interactions, as well as the leadership abilities to guide, mentor, and manage a high-performing engineering team.
Key Responsibilities
• Team Management & Hands-On Contribution: Lead, manage, and grow a team of firmware engineers while remaining a core individual contributor. Dedicate a significant portion of your time to writing code, conducting code reviews, and resolving low-level technical challenges.
• Security Architecture & Boot Flow: Architect, develop, and optimize embedded software solutions with a primary focus on end-to-end platform security, including Secure Boot, hardware Root of Trust (RoT), and verified boot pipelines.
• Protocols & Provisioning: Implement and manage attestation schemes such as SPDM for device authentication and remote measurement, alongside secure factory and field secure provisioning workflows.
• Firmware Signing & Lifecycle Management: Design and maintain cryptographic firmware signing infrastructure, secure update pipelines, and robust revocation mechanisms (such as anti-rollback counters, key revocation lists, and certificate revocation).
• Debugging & Security Analysis: Diagnose and resolve complex hardware/software and cryptographic failure modes using advanced debugging tools (JTAG, GDB, logic analyzers).
• Cross-Functional Collaboration: Partner closely with security experts, hardware engineers, and system architects to define roadmaps and deliver scalable embedded security solutions, while contributing to open-source security standards or embedded projects.
