Job summary

Rune Technologies in Seattle is building the quality backbone for TyrOS, a critical logistics platform used by military customers. You will own QA across the full software lifecycle, design automated tests, and contribute to scalable QA processes from the ground up.

You will collaborate with engineers, Mission Managers, and TechOps to ensure releases meet strict performance, accessibility, and reliability standards in operational environments.

Qualifications

• 2+ years of Quality Assurance, Test Automation, or SDET experience supporting modern web applications.
• Hands-on experience with Playwright or comparable end-to-end testing framework (Cypress or Selenium).
• Experience building and maintaining automated testing suites.

Responsibilities

• Own quality across the TyrOS software development lifecycle, ensuring new features meet quality standards before production.
• Review every pull request destined for the main branch by validating testing evidence, spinning up ephemeral environments, verifying functionality, and approving or blocking releases.
• Build, maintain, and expand Playwright end-to-end test suite covering critical user workflows across TyrOS.
• Design automated tests that reduce manual regression testing and improve engineering velocity over time.
• Execute release regression testing to ensure production readiness before every software release.
• Perform non-functional testing including performance validation, accessibility testing, data integrity verification, and basic load testing.
• Partner with software engineers during feature planning to review acceptance criteria and determine automated checks.
• Collaborate with Mission Managers and Forward Deployed Engineers to validate deployments and workflows.
• Establish QA metrics, documentation, testing standards, and repeatable processes that scale with the engineering org.
• Continuously improve testing strategy through automation, tooling, and process improvements.
