Senior QA Automation Engineer (Platform)

About the Role: Our QA-Core team exists so every engineering team at Upgrade can test their software quickly and trust the result. We are seeking a Senior QA Automation Engineer on the team to architect and build test automation infrastructure, tooling, and agentic solutions to increase engineering productivity. This is not a traditional product QA role - it’s a build role. You will work closely with our product teams to understand their automation requirements, design services from scratch, ship them to production clusters and own them. This is a fully remote position open to candidates who are based in the US. Our Core Technologies Include: Java, Python, Kubernetes, Selenium WebDriver, Playwright, TestNG, Maven, Git, Jenkins, ArgoCD, SQL, Grafana, SumoLogic, Docker, Gatling, Claude Code, MCP server What You’ll Do: - Design and own automation framework for functional and performance testing. - Build agents to automate existing QA/testing workflows and remove engineering friction. - Build the applications and services that automation depends on, deploy them, and operate them in production environments. - Take prototypes all the way. Build demos in a timely manner, gather feedback from the teams who'd use it, and iterate through successive versions until it's hardened, monitored, and running with matured quality. - Identify gap areas in existing frameworks and tools, and iterate toward solutions that close them. What We Look For: - 5-7+ years building production software, with demonstrated depth across test infrastructure, test frameworks, and developer tooling, and working knowledge of platform engineering. - Proven track record building agentic solutions and test automation frameworks from the ground up — designed, shipped, iterated on, and adopted as part of how other engineers work. - Fluency with agentic coding tools as part of your daily workflow: ability to orchestrate multiple agents to execute, review agent-generated PRs. - Hands-on experience with micro-services, Kubernetes and managing deployment lifecycle - Ability to take an ambiguous problem statement to a scoped, defensible solution independently. What We Offer You: - Competitive salary and stock option plan - Paid coverage of medical, dental and vision insurance - Flexible PTO - Opportunities for professional growth and development - Paid parental leave - Health & wellness initiatives
