Software Development Test Engineer (SDET)

To ensure a fair and consistent evaluation process, candidates are expected to complete all interviews and assessments independently and without the use of artificial intelligence tools (including AI-generated responses, prompts, or real-time assistance). Use of AI throughout the application and recruiting process may result in removal from consideration.

Our goal is to get to know your authentic experiences, communication style, and problem-solving approach. This is a fully onsite position located at our corporate campus in Phoenix, AZ. There is no opportunity for remote work.

We are seeking a Software Development Engineer in Test (SDET) to join our SDET team. This role is focused on designing, building, and maintaining automated testing solutions that enable our development teams to deliver high-quality software with confidence and speed.

You will write production quality code to create reliable, scalable test automation across UI, API, and data layers. You will work as a peer alongside developers—participating in code reviews, improving application testability, and contributing to our automation frameworks and CI/CD pipelines.
