At KNOWiNK, we build technology that powers elections across the country. That means quality isn't just a nice to have — it's everything. We're looking for an SDET who lives at the intersection of engineering and testing, someone who thinks in code, cares deeply about coverage, and wants to build automation that actually makes a difference. If you're the kind of person who gets excited about finding a bug before it ships, you're going to fit right in here.

What you'll be doing

• Design, build, and maintain automated test frameworks and test suites across web, mobile, and API layers
• Write clean, reusable test code that integrates smoothly into our CI/CD pipelines
• Collaborate with developers and product early in the cycle to identify testability gaps and build quality in from the start
• Perform manual and exploratory testing when automation isn't the right tool for the job
• Own defect documentation and tracking from discovery through resolution
• Contribute to code reviews on test automation with an eye for maintainability and coverage
• Support performance and regression testing efforts across releases and hotfixes
• Help maintain and improve QA documentation, standards, and processes as we grow
