Job DescriptionJob Description

Software Quality Assurance EngineerKNOWiNK — St. Louis, Missouri

We're looking for a solid mid-level QA Engineer who genuinely cares about shipping quality software, and who wants to build automation, not just run it. You'll be hands-on with test automation across our platform, working closely with developers and product to catch problems early and keep our test suites doing the heavy lifting. You don't need to have all the answers yet, but you bring real curiosity, solid instincts, and a track record of making things better.

What you'll be doing

• Design, build, and maintain automated test suites for features, releases, and hotfixes across web, mobile, and API platforms
• Own regression, integration, smoke, and performance testing through automation, expanding coverage as the platform grows
• Integrate automated tests into our CI/CD pipelines so quality gets checked on every build, not just before release
• Use manual and exploratory testing where it actually adds value — new features, edge cases, and anything automation hasn't caught up to yet
• Identify, document, and track defects through to resolution with clear communication
• Partner with developers and product managers on requirements and acceptance criteria, building testability in from the start
• Help document QA processes and contribute to team testing standards, with an eye toward automating anything repetitive
• Contribute to QA metrics and help communicate quality trends across the team

What we're looking for

• 2+ years of hands-on software QA experience, with real automation work under your belt (not just exposure)
• Experience with test automation tools like Selenium, Cypress, or Playwright
• Scripting or programming experience in Python, JavaScript, Java, or similar
• Experience with API testing tools like Postman or REST Assured, and building automated API test suites
• Comfort working inside CI/CD pipelines and designing tests to run there
• Working knowledge of Agile/Scrum methodologies
• Strong attention to detail and solid debugging instincts
• Clear communicator who works well across teams

Nice to have

• Experience with performance testing tools like JMeter, K6, or LoadRunner
• Exposure to cloud platforms like AWS, Azure, or GCP
• Experience with Docker or containerized testing environments
• Experience setting up test reporting/dashboards to track automation coverage over time

What success looks like

First 90 daysYou know the product, you know the team, and you're already contributing automated test coverage, not just planning to.

First 6 monthsYou're running point on test automation for features end to end, catching bugs before they reach production, and shrinking the manual testing load as you go.

First yearYou're a trusted, go-to member of the QA team with real ownership over your area of the automation suite.
