Data Test Engineer
Department: Platforms and Infrastructure
Location: Boston, Santa Barbara, Seattle
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.
More than a candidate that checks every box, we’re looking for people who are excited to work, learn, and grow at Sonos—no matter their background or how they identify. If that’s you, we hope you’ll apply for this role.
You want to be part of a team.
You come with new ideas and a unique point of view. You look forward to collaborating with a diverse team of individuals. You assume everyone’s best intentions, welcome a healthy debate, and embrace differing opinions. You eagerly seek and give help. Transparency tops your list of values, and you proactively contribute to a culture of respect and inclusion.
You enjoy a challenge.
Inquisitive and focused, you see every challenge as an opportunity. You’re ambitious and comfortable making mistakes because you learn from them and bounce back quickly. You would rather create the future than wait for it. You prioritize long-term value over short-term objectives.
You love to listen.
You approach every interaction with curiosity and a desire to understand. You want to make a positive impact in the world. You’re passionate about culture and know the power that music, film, podcasts, games, and stories have to bring people together.
