KEY RESPONSIBILITIES:

• Developing, porting, debugging, and documenting core firmware support for various DRAM technologies including DDR4, LPDDR4/4x, DDR5, LPDDR5/5x RDIMM, LRDIMM, 3DS, etc., on Mobile, and Enterprise SoCs.
• Supporting emulation/simulation teams during pre-silicon phase to validate memory hardware and firmware.
• Working closely with hardware validation teams to optimize memory signal integrity, achieve highest possible performance and robust feature support.
• Assist memory validation teams with debug from initial power-on to achieve full functionality of all features in a timely manner.
• Developing custom memory firmware features for internal and external customers.
• Engage with technical leads to understand firmware scope and work on implementation to meet schedules and milestones.
• Work with internal and external teams to ensure highest level of quality and satisfaction throughout firmware lifecycle.
• Must be well-organized, technically oriented, and a self-starter with a demonstrated ability to work collaboratively and coordinate activities with geographically distributed technical teams.
• Desire to work and succeed on fast-paced and highly dynamic environments

QUALIFICATIONS:

Bachelor’s or Master’s degree (preferred) in Computer Science, Computer Engineering, Electrical Engineering, or equivalent with 6-9 years of experience

Primary Skills:

• Expertise in low-level C programming & debugging for embedded systems.
• Prior experience and/or exposure to testing platforms (Simulation and/or Emulation)
• Familiarity with memory industry standards and technologies such as JEDEC, SPD Data, I2C/I3C, DDR4/5, LPDDR4/4x/5/5x UDIMM, RDIMM, LRDIMM, 3DS, ECC, Mode Registers, Self-Refresh, etc.
• Experience with or knowledge of DRAM Initialization/training algorithms, memory timings, addressing, overclocking, etc.
• Experience in debugging memory initialization and training issues.

Secondary Skills:

• Good understanding of firmware development cycle, integration and verification/validation for pre-si and post-si for SoC designs.
• Ability to methodically root-cause complex failure mechanisms at the IP, subsystem and/or system level.
• Experience in hardware/software interfaces and debugging sophisticated issues in CPU and firmware using JTAG, source code debuggers and other tools.
• Experience with source control systems including git/gerrit
• Excellent written and verbal communication and presentation skills.
