Senior Memory Subsystem Firmware Engineer

NVIDIA's SoC Memory Subsystem team is looking for a strong, senior DRAM firmware engineer to own memory firmware from architecture through production silicon. You'll lead in areas of DRAM initialization and training across DDR/LPDDR, drive interface tuning across process, voltage, and temperature corners, and set the direction for how we take new memory interfaces from pre-silicon to production. What you'll be doing: Own DRAM firmware across its lifecycle — architecture, implementation, silicon bring-up, and production tuning. Design and implement DRAM initialization and training sequences: training protocols, calibration algorithms, and their firmware implementation. Characterize and tune the DRAM interface across PVT (process / voltage / temperature) variation to hold margins across corners. Drive the memory bring-up and validation strategy; root‑cause complex hardware/software interactions in the lab and in pre‑silicon. Set firmware quality bar — code review, profiling, and coverage — and mentor early‑career engineers on the team. Refining our Interface bring up and validation strategy. What we need to see: 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 their implementation in firmware. Deep understanding of DRAM interfaces and how PVT (process / voltage / temperature) 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. Ways to stand out from the crowd: 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.
