Principal Design Verification Engineer

About SiFive

SiFive is an idea-to-silicon company founded by the inventors of RISC-V to simplify the design and production of custom SoCs.

As the leading commercial provider of RISC-V processor IP, SiFive is on a mission to help engineers design custom chips for domain-specific solutions for many markets, including 5G, edge AI, enterprise networking, storage, and consumer devices.

Industry-leading innovators, including six of the top ten semiconductor companies, are working with SiFive thanks to our proven success, deep expertise, and rich partner ecosystem. With SiFive’s rich IP ecosystem and accessible design platform, every market has access to the development of workload-focused hardware needed to design next-generation products.

SiFive is looking for a passionate technical leader who has demonstrated an ability to lead a technical team and drive the entire design verification lifecycle. This verification position is a highly visible role, the simple purpose of which is to ensure the silicon works. What will you work on when you join our team? By its design philosophy, RISC-V is highly configurable, and we have several different configurations in our design pipeline, with various combinations of supported instruction set and with various peripherals and bus interconnect architectures. Defining and implementing design verification methodologies that can accommodate such variation is a challenging task, to be addressed in this role.


  • Architect test methodologies applicable to a wide range of processor and SoC designs including memory virtualization (Paging and Hypervisors), various levels of caches and industry standard bus protocols (e.g., AMBA, TileLink, PCIe).
  • Develop tools, test benches, and test suites (UVM, C++/C or otherwise, as needed) to execute test plans.
  • Write functional coverage, analyze both code and functional coverage, and close coverage holes.
  • Develop and use unit level test benches that use constrained random stimulus.
  • Write directed assembly tests as appropriate to test CPU functions.
  • Drive the execution of test suites and analyze test results, including RTL or higher-level debug of test failures.
  • Build test plans to implement these strategies, considering issues such as design feature priority, potential customer impact, coverage metrics generation and measurability, etc.
  • Provide technical leadership for verification engineers and coordinate technical teams to execute our verification strategies to meet program goals.
  • Own all operational metrics and support for your team’s verification duties.
  • Collaborate closely with a geographically distributed team on feature specifications, test plans and failure analysis.
  • Interface with other cross functional leaders to understand requirements, set priorities and communicate direction and progress.
  • Foster career growth and a strong team culture.
  • Recruit, hire, mentor, and coach technical staff.


  • A minimum of 10 years of recent experience with standard verification tools and methodologies (SystemVerification/UVM, Verdi/DVE, Verilog, Makefiles, scripting languages, etc.)
  • Solid understanding of and experience with verification of CPU and SoC architectures including test planning, constrained random test generation, test stimulus, code coverage, functional coverage.
  • A thorough understanding of the high-level verification flow methodology (test plan generation, test generation, failure analysis, coverage analysis and closure).
  • Ability to effectively assess the current state of a design’s verification posture, remaining state space to be covered, and efficient methods to achieve verification closure.
  • Familiarity with and/or ability to learn languages and methodologies that are not part of the industry-standard approach to verification (Scala, Chisel, etc.).
  • Prior verification technical leadership required and some management experience is a plus.
  • Good interpersonal skills to listen to diverse points of view and influence people from different disciplines.
  • Experience coordinating design verification activities with teams located across the world.
  • An unwavering dedication to product quality.
  • A passion for people management and mentorship.
