Software Test Engineer Jobs in Seattle, WA (NOW HIRING)

At Symetrix, we’re driven by a bold vision: to build exceptional products, grow extraordinary people, and make a positive impact in the world. We bring innovation to life through high-performance audio and video solutions, supported by world-class customer care. From classrooms and courthouses to stadiums and large venues, our technology powers meaningful experiences every day.

We’re seeking a Senior Test Engineer to play a critical role in ensuring the quality, reliability, and performance of our hardware and software solutions. In this role, you’ll lead testing efforts end-to-end, from strategy and planning through execution and final product release approval.

You’ll own both manual and automated testing processes, helping to improve systems and expand test coverage. While this role includes providing guidance and support to an associate engineer, it is primarily hands‑on and focused on technical contribution and quality outcomes.

You’ll also collaborate cross‑functionally and support customer‑facing teams in resolving real‑world challenges. If you’re passionate about building high‑quality products and enjoy solving complex technical problems, this is an opportunity to make a meaningful impact.
