Senior Memory Subsystem Firmware Engineer - US, CA, Santa Clara | Nvidia Job

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.

NVIDIA is on the move and our technology and vision position us as one of the world’s most desirable employers. We have some of the most forward-thinking and versatile people on our journey. If you're inventive and autonomous, we want to hear from you!
