Senior Memory Subsystem Firmware Engineer

Job Title

Senior Memory Subsystem Firmware Engineer

Role Summary

Lead development and ownership of DRAM/memory firmware from architecture through production silicon for high-performance SoC memory subsystems. Work across pre-silicon and silicon bring-up, validation, and production tuning with cross-functional hardware and lab teams.

Experience Level

Senior — typically requires 6+ years of relevant DRAM/memory firmware development experience.

Responsibilities

Primary responsibilities include designing firmware and driving memory bring-up and validation.

• Own DRAM firmware lifecycle: architecture, implementation, silicon bring-up, and production tuning.
• Design and implement DRAM initialization and training sequences, including calibration algorithms and firmware implementations.
• Characterize and tune memory interfaces across PVT (process, voltage, temperature) to maintain timing margins.
• Drive memory bring-up and validation strategy; diagnose and root-cause complex hardware/software interactions in lab and pre-silicon environments.
• Define and enforce firmware quality practices: code review, profiling, and test coverage; mentor early-career engineers.

Requirements

Must-have technical skills and experience; nice-to-have items listed separately.

• Must-have: 6+ years of DRAM/memory firmware development experience for high-speed LPDDR or system DDR.
• Must-have: Strong command of DRAM initialization and training protocols, calibration algorithms, and firmware implementation.
• Must-have: Deep understanding of DRAM interfaces and how PVT variation affects timing, training, and margining.
• Must-have: Proficiency in C/C++; familiarity with data structures, compilers, build systems, and version control.
• Must-have: Strong debugging skills and ability to decompose complex, ambiguous failures from first principles.
• Nice-to-have: Experience across DDR, LPDDR, HBM and with multiple DRAM vendors.
• Nice-to-have: Signal-integrity intuition and comfort with analog/mixed-signal behavior.
• Nice-to-have: Understanding of ASIC boot architecture.

Education Requirements

BS or MS in Electrical Engineering, Computer Engineering, Computer Science, or a related field — or equivalent practical experience.
