System Verification Engineer

Department: Hardware

Location: Shanghai

Req#: 5780

Quality is one of Sonos’ highest priorities. As a System Verification Engineer you will be responsible for owning the verification of all the relevant hardware subsystems which make up our products and for ensuring that the system-level hardware product quality meets or exceeds the level that our customers have come to expect. You will be an integral member of the product development team, defining verification strategies, implementing and debugging individual verification tests designed to ensure that our hardware functions as specified. You will have overall responsibility for hardware quality and performance verification throughout the product lifecycle - from development to end-of-production. 

This position will specifically focus on the qualification of all electrical, mechanical and packaging components/sub-assemblies that will be procured by our contract manufacturers in Malaysia. Responsibilities will include writing qualification plans and defining test schedules, developing automated testing, communicating the test results, documenting and investigating failures, troubleshooting found issues to resolution with the product design teams, and working with our manufacturing teams to ensure both a smooth transition into volume manufacturing and support continuous production.

About You

  • Collaborate and communicate effectively:

    • Oversee the actions of any Malaysia factory personnel assigned to execute qualification plans and/or assist with ECRs

    • Collaborate with other Sonos Product Development Engineers, especially the CaSE and HWV teams, for ongoing product development, redesign and support
