Rambus, a premier chip and silicon IP provider, is seeking to hire an exceptional Senior Principal Engineer (SPE) to join our CXL SoC Firmware Engineering team. Candidates will be joining some of the brightest inventors and engineers in the world to develop products that make data faster and safer.

As a SPE, the candidate will report to the Firmware Engineering Director and lead the security firmware development for a Compute Express Link (CXL) System-On-Chip (SoC). The individual will be responsible for defining the firmware architecture for the security sub-system in the SoC, as well as designing and implementing firmware and software tools for secure boot, Root of Trust (RoT), attestation, authentication, key and asset management. The individual will deliver the firmware feature-set necessary to ensure secure operational environments for CXL SoCs in memory, data center, and AI/ML applications.

The ideal candidate will possess prior experience with hardware cryptographic engines, security handshakes, device lifecycle stages, and revocation. The candidate needs to be deeply hands-on and capable of working independently and in a team with experienced firmware engineers. The individual will execute the embedded software development lifecycle for firmware running on RISC-V CPUs and a Real-Time Operating System. The candidate needs to have solid experience with embedded system bring-up, testing, and troubleshooting. The candidate will interact extensively in a tight team environment with employees in other disciplines and geographies.

• Experience with real time OS techniques including preemptive multi-tasking schedulers, multi-threaded execution, semaphores, mutexes, and interrupts.
• Proficient in writing performance optimized code for CPU and memory constrained environments.
• Ability to technically lead a small team of firmware developers and work independently.
• Hardware bring-up experience using JTAG debug tools.
• Experience working in lean development organizations and/or startups.
• Excellent written and verbal communication skills.

Desired Skills:

• Writing software for embedded RISC-V platforms, System-On-Chip (SoC), or x86 platforms.
• Experience using RTOS such as ThreadX, Zephyr, and FreeRTOS.
• Working knowledge of Public Key Infrastructure (PKI) private and public keys, certificates, and X.509 trust models
• Experience implementing protocols such as SPDM, MCTP, DOE, and TLS/SSL.
• Python experience
• Understanding of PCIe Integrity and Data Encryption (IDE) key management, DICE, Caliptra, CMA.
• Experience with TSP (Trusted Execution Environment Security Protocol).
