Sound Tech Jobs in California (NOW HIRING)

We are looking for a highly motivated, experienced, and versatile Principal Verification Engineer to join our team. In this role, you will own the end-to-end verification platform and program for ASIC (Applied Specific Integrated Circuit) drivers and networking software, with full accountability for its overall quality, reliability, and success. You will design, develop, and own the verification frameworks, test environments, and automation infrastructure across our current and next-generation products, lead verification strategy and standards across multiple teams, serve as the go-to technical authority for the most complex verification challenges, and mentor and grow engineers across the organization. You will be working alongside a closely-knit cross-functional team of experienced software, hardware, and ASIC engineers.

Job Responsibilities

      Own the end-to-end verification platform and program for ASIC drivers and networking software, taking full accountability for its overall success, quality, and reliability.
      Design, develop, and own robust, scalable verification frameworks and automation tools in Ruby and Python for ASIC drivers.
      Build and maintain comprehensive test environments, test suites, and verification infrastructure to validate ASIC driver and networking software functionality, performance, and reliability.
      Drive verification strategy, planning, and standards across multiple teams, including test plan development, coverage analysis, coverage closure, and the best practices and methodologies adopted across the product area.
      Replicate and drive the most complex customer-reported and internally-discovered issues to resolution, performing deep root cause analysis across the software, driver, and hardware layers.
      Conduct thorough code reviews of verification code, provide constructive feedback, and champion engineering best practices across multiple teams.
      Mentor and grow engineers across teams through pair programming and design reviews, fostering their development into senior and staff-level technical contributors.
      Collaborate closely with software, hardware, and ASIC engineers to ensure verification gaps are identified, defects are properly reproduced, and fixes are validated.
      Build and maintain tools to generate network traffic, simulate test scenarios, and measure performance and reliability.
      Serve as the go-to technical authority for ASIC driver verification, resolving the most complex and ambiguous issues that cross software, driver, and hardware boundaries.
      Influence hardware and software teams on verification sign-off criteria, testability improvements, and debug capabilities.
      Lead cross-team technical initiatives and align stakeholders across engineering functions on verification strategy, priorities, and roadmap.
      Lead hiring and growth of the verification organization across the program, raising the technical bar through mentorship and code reviews.
      Champion innovation in verification methodology, tooling, and process improvements across the teams you lead.
      Contribute to the overall technical direction of the verification platform, including tooling strategy, technology selection, and long-term roadmap for the product area.
