Principal Digital Verification Engineer (Memory Interface IP- HBM/DDR/LPDDR)

Principal Digital Verification Engineer (Memory Interface IP- HBM/DDR/LPDDR)

Synopsys is the leader in engineering solutions from silicon to systems, enabling customers to rapidly innovate AI-powered products. We deliver industry-leading silicon design, IP, simulation and analysis solutions, and design services. We partner closely with our customers across a wide range of industries to maximize their R&D capability and productivity, powering innovation today that ignites the ingenuity of tomorrow.

You have spent the better part of a decade verifying complex ASIC designs, and you know that the hardest bugs are the ones that hide in corner cases three layers deep in a protocol handshake. You have worked on memory interfaces long enough to know that HBM, DDR, and LPDDR are not just acronyms, they are ecosystems with timing constraints, power states, and failure modes that can sink a tapeout if you miss them.

You do not wait for a design to be "ready" before you start thinking about verification. You are already mapping out testbenches, coverage models, and corner cases while the RTL is still being written. When something does not make sense in a spec, you ask. When a test fails in a way that should not be possible, you dig until you find the root cause, not just a workaround.

You have built verification environments from scratch and you have also inherited messy ones and made them better. You know how to balance thoroughness with schedule pressure, and you can explain a coverage gap to an architect without making it feel like blame. At this point in your career, you are not just verifying designs, you are shaping how verification gets done, mentoring engineers, and setting the standard for what good looks like.

Design and build verification environments for Interface IP protocols including HBM, DDR, LPDDR, and AMBA using SystemVerilog and UVM

Write detailed test plans that cover functional scenarios, corner cases, and protocol compliance for memory controller and interface IP designs

Develop reusable verification IP and testbenches that can be adapted across multiple projects and IP variants

Work directly with design and architecture teams to identify bugs, clarify specifications, and close coverage gaps before tapeout

Run functional coverage analysis, track metrics, and drive coverage closure across complex multi-protocol environments

Mentor junior verification engineers on UVM best practices, debugging techniques, and verification strategy

Use simulation tools like VCS or ModelSim to execute regression suites, debug failures, and validate design changes

Deliver Interface IP that powers memory subsystems in AI accelerators, mobile SoCs, and high-performance computing platforms used across the industry

Reduce post-silicon bugs and customer escalations by catching issues early through rigorous verification and coverage-driven testing

Shape the verification methodology and standards that the team will use for the next generation of memory IP products

Accelerate project schedules by building reusable verification components that cut bring-up time on future designs

Raise the technical bar across the verification team by mentoring engineers and sharing hard-won lessons from complex bring-ups

Contribute to the quality and reputation of Synopsys IP, which directly affects customer trust and product adoption

Help define what "done" means for verification, ensuring that coverage, corner cases, and compliance are never compromised under schedule pressure

Bachelor's or Master's in Electrical Engineering or Computer Engineering with 8 to 10+ years of hands-on ASIC or SoC verification experience

Proven track record verifying Interface IP protocols such as HBM, DDR, LPDDR, or AMBA in production-level designs

Strong proficiency in SystemVerilog and UVM, including building testbenches, writing assertions, and developing verification IP

Deep understanding of digital design concepts, timing, protocol compliance, and memory subsystem architecture

Experience using simulation tools such as VCS, ModelSim, Xcelium, or equivalent in a regression and debug workflow

Demonstrated ability to drive functional coverage closure and deliver fully verified IP on schedule

Experience with HBM2, HBM3, DDR4, DDR5, LPDDR4, or LPDDR5 is a strong plus

You can look at a failing test and quickly narrow down whether it is a testbench issue, a design bug, or a timing problem without burning a day in the debugger

You push back when a test plan is too shallow or a coverage model is missing a critical scenario, and you do it in a way that helps the team get better

You can explain a complex protocol violation to a design engineer in two sentences without losing the technical nuance

You are comfortable working across time zones and teams, coordinating with architects in one region and design engineers in another without losing momentum

You take ownership of the verification closure process and do not wait for someone else to tell you what needs to be done next

You mentor junior engineers by showing them how to think through a problem, not just how to fix the immediate issue in front of them

You will be part of a highly skilled and motivated verification team focused on delivering cutting-edge Interface IP solutions. The team is dedicated to maintaining the highest standards of quality and performance, working collaboratively to tackle complex verification challenges. You will have the opportunity to work alongside industry experts and contribute to the development of next generation technologies.
