DDR PHY System Design Engineer
QualcommJob Title
DDR PHY System Design Engineer
Role Summary
Design and architect high-speed DDR PHY systems for mobile, compute, AI/ML, 5G, and automotive products. Work within the mixed-signal IP DDR PHY team to develop system timing, link training, and validate designs from concept through production.
Experience Level
Mid-level. Typical candidate has 5–10 years of hands-on DDR PHY system design or architecture experience; equivalent experience considered per education level (see Education Requirements).
Responsibilities
Accountable for system-level DDR PHY architecture, timing, and validation across product development stages.
- Define and own DDR PHY system and architecture for product requirements.
- Develop on-die and off-chip system timing budgets and verify timing closure.
- Specify and validate link budgets and training procedures for DRAM interfaces.
- Collaborate with signal-integrity, power-delivery, and mixed-signal teams to meet performance and yield targets.
- Lead cross-functional design reviews and coordinate activities across global teams.
- Support bring-up, production validation, and problem resolution for high-speed links.
Requirements
Core technical skills and experience required; preferred skills that improve fit are listed separately.
- Must-have — 5–10 years of DDR PHY system design or architecture experience focused on high-speed memory interfaces.
- Must-have — Strong knowledge of JEDEC DDR standards (LPDDR, PCDDR, HBM) and their system implications.
- Must-have — Demonstrated experience with link budgets, training algorithms, and validating high-speed links.
- Must-have — Strong written and verbal communication; proven ability to coordinate across global engineering teams.
- Nice-to-have — Signal integrity and power-delivery experience for server-class products.
- Nice-to-have — Familiarity with advanced process nodes and mixed-signal design constraints.
- Nice-to-have — Understanding of design-for-yield, production challenges, and reliability for high-speed links.
- Nice-to-have — Scripting experience (Unix/Perl/Tcl) and comfort automating analysis tasks.
Education Requirements
Required: Bachelor's degree in Electrical Engineering (or related science/engineering field). Preferred: Master’s degree in Electrical Engineering. Qualcomm also lists degree/experience equivalencies: Bachelor’s + 4+ years relevant ASIC design/verification/validation/integration experience; Master’s + 3+ years; PhD + 2+ years. Equivalent practical experience will be considered where specified.
