Data Test Engineer

Department: Platforms and Infrastructure

Location: Boston, Santa Barbara, Seattle

Req#: 5389

At Sonos, we are passionate about bringing music into every home.  To fulfill this mission, we have developed an unquenchable thirst for data.  We use data to understand how our products are performing, which features need to be improved, design future products, optimize our supply chain and sales channel performance, and learn how our customers experience music in their homes.

  Sonos has mountains of data, but that data is only useful if it is collected, stored and presented accurately.  As a Senior Test Engineer on our Enterprise Supply Chain Systems & Data Team, you will be responsible for performing data analysis, discovering data anomalies, generating test data, and implementing data quality improvements while participating in an Agile environment. You will be working closely with end users, ETL developers, Data Architects, Report Developers and functional teams.

 In addition to being an accomplished tester, the perfect candidate will also be an excellent teacher, and will help the entire team test better.  You will be responsible for communicating risks, helping your fellow developers find inconsistencies in the code, and ultimately insure our commitments are delivered completely.
