Job Description
SDET – Software Development Engineer in Test

KNOWiNK St. Louis, Missouri (An On-site Role)

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
What we're looking for
2-4 years of SDET or test engineering experience
Solid programming skills in Python, JavaScript, Java, or similar
Hands-on experience with automation frameworks like Selenium, Cypress, or Playwright
Experience integrating tests into CI/CD pipelines
API testing experience with tools like Postman or REST Assured
Comfortable working in Agile/Scrum environments
Strong analytical thinking and sharp eye for edge cases
Clear communicator who collaborates well across engineering and product
Nice to have
  • Experience with performance testing tools like JMeter, K6, or LoadRunner
  • Mobile testing experience on iOS and/or Android
  • Familiarity with security testing practices
  • Exposure to cloud platforms like AWS, Azure, or GCP
  • Experience with Docker or containerized test environments
  • Background in elections tech, civic tech, or similarly high-stakes software
What success looks like

First 90 days

You understand our product, our stack, and our testing gaps, and you're already writing automation that matters

First 6 months

Your test coverage contributions are measurably reducing regression time and catching bugs earlier in the cycle

First year

You're a core part of how quality gets built into our product, not just validated at the end

Sound like you? We'd love to hear from you.
