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.
