As a member of the Sonos Smart Speaker team your role will be to help build and qualify the embedded OS that ensures our customers have high quality audio experience. You will have a direct impact on the business, advancing major player components such as the core audio pipeline, system software and (wireless) networking. You will also get to work on our key home theater technology and partner with development, operations and support teams. You will be expected to understand the features being built and help determine the best course of action to test those features in an automated fashion.

If you love music, solving challenging problems and delivering high-quality products, we want to talk with you!
About You

You're not like everyone else.

You bring a unique perspective to the table. Transparency tops your list of values. Your smarts and creativity are off the charts, matched only by your humility. You want to collaborate with a team of diverse talent. 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 unafraid to make mistakes because you learn from them and bounce back quickly. You don't stop until you get it right. "Impossible" isn't in your vocabulary. You're more interested in creating the future than waiting for it.

You love to listen.

You start every interaction from a place of listening and seeking to understand. You're culturally connected. You remember your first concert. You can readily recommend a binge-worthy show on Netflix, Hulu or HBO. You can't sit in traffic without a great audiobook, podcast or album. You can make a killer playlist. Your idea of a good weekend includes watching a movie or playing a video game.

What You’ll Do
Collaborate with other members of the Smart Speaker Team to deliver features that are implemented, tested, and documented at the end of each sprint.
Review requirements, behavior specifications, and design documents to begin test development early and uncover issues prior to implementation.
Proactively work with developers to debug software and hardware solutions during new product development.
Define and develop test automation to improve testing efficiency and coverage.
Write (automated) test cases that exercise audio pipeline and integrate them into the current framework.
Investigate log, track, and triage bugs to determine root cause and establish prioritization.
Monitor, debug, and fix breakages within our automated infrastructure.
Provide technical leadership and mentoring to junior test engineers.
Add and democratize new forms of data and metrics to allow the team to make decisions on where to focus and improve our tests.
Be an active participant and engaged part of your Scrum team – you are the voice of both quality and the customer during the development process.

Skills You’ll Need
Strong knowledge of software test methodologies & test automation principles applied to manual testing of embedded systems.
Some experience in Python, Java or C/C++ or shell scripting in a Linux environment.
Experience in using automation frameworks and automation testing strategies.
Strong networking knowledge with expertise in troubleshooting and debugging.
Experienced in testing embedded systems preferably Linux (user and kernel space).
Demonstrated ability of defining and implementing software test plans, as well as automation, for audio or embedded systems.
Excellent written and verbal communication skills.
BS or MS in Computer Science or Electrical Engineering, or equivalent experience.
