Senior Memory Subsystem Firmware Engineer

Responsibilities Own DRAM firmware across its lifecycle — architecture, implementation, silicon bring‑up, and production tuning. Design and implement DRAM initialization and training sequences, including training protocols, calibration algorithms, and their firmware implementation. Characterize and tune the DRAM interface across PVT (process / voltage / temperature) variation to maintain margins across corners. Drive the memory bring‑up and validation strategy, root‑cause complex hardware/software interactions in the lab and pre‑silicon. Set firmware quality bar — code review, profiling, and coverage — and mentor early‑career engineers on the team. Refine interface bring‑up and validation strategy. Qualifications BS or MS in Electrical Engineering, Computer Engineering, Computer Science, or related field (or equivalent experience). 6+ years of relevant DRAM / memory firmware development for high‑speed LPDDR or system DDR memories. Strong command of DRAM initialization and training protocols, calibration algorithms, and firmware implementation. Deep understanding of DRAM interfaces and how PVT variation affects timing, training, and margining. Proficiency in C/C++, with a solid grasp of data structures, compilers, and build and version‑control tooling. Excellent debugging skills; able to decompose hard, ambiguous failures from first principles. Preferred Experience Breadth across DDR / LPDDR / HBM and multiple DRAM vendors; signal‑integrity intuition and comfort working with analog/mixed‑signal behavior; understanding of ASIC boot architecture. Compensation Base salary range for Level 4: $184,000 – $287,500; for Level 5: $224,000 – $356,500. You will also be eligible for equity and benefits.
