Software Development Engineer in Test (SDET)

The role of a Software Development Engineer in Test (SDET) is critical to CodeChem's project quality and overall success, from planning to supporting primary KPIs such as product reliability and customer satisfaction. An SDET at CodeChem plays an essential role in building and maintaining strong end-to-end test coverage across the product life cycle, from planning and development through testing, deployment, and support.

Growth at CodeChem is a team effort. We learn from each other, push each other, and make the work better together. If that's how you like to work, join us.

About the role
