Description

About the role We are looking for a Senior QA Engineer to own quality across our cloud-based platform. This is a high-impact, standalone role working closely with multiple engineering teams. You will be the single point of accountability for quality, driving automation, enforcing standards, and ensuring releases meet a high bar. This role is approximately 70% focused on test automation and 30% on manual QA, with direct involvement in the release process. You will help the team move faster without sacrificing reliability and you will be expected to push back when quality is at risk. Longer-term, this role will play a key part in building and leading a QA function, including hiring and mentoring additional QA engineers as the organization scales. What you'll do Test Automation Design, build, and maintain automated test suites covering the cloud platform end-to-end. Expand automated test coverage across: Web applications APIs and web services Data workflows (MongoDB, Postgres) AI-driven and event-based workflows Partner with engineers early in the development lifecycle to: Define test strategies Identify edge cases Improve testability of features Use Playwright and modern automation practices to reduce regression risk and release friction. Leverage AI-assisted tools (e.g., Cursor, GitHub Copilot) to improve testing velocity and quality. Manual QA Execute exploratory, regression, and release testing. Validate complex workflows where automation coverage is incomplete or evolving. Identify gaps in automation and systematically convert manual test cases into automated tests. Provide high-signal feedback on usability, edge cases, and risk areas. Release Quality & Standards Actively participate in the release process. Ensure releases meet defined quality standards and acceptance criteria. Perform release sign-offs and risk assessments. Identify recurring quality issues and drive systemic fixes—not just one-off bug resolution. Test Case Management & Process Own QA test case management, including: Test planning Test case creation and maintenance Traceability between requirements, tests, and defects Work closely with Product and Design teams (via Jira and Figma) to ensure requirements are testable and clearly understood. Continuously improve QA processes, documentation, and standards across teams. Leadership & Accountability Serve as a strong quality advocate across the organization. Hold engineering teams accountable to quality standards. Be confident, direct, and constructive when raising concerns. Help define what “done” truly means. Prepare to help build and manage a QA team as the organization grows. Qualifications Education & Experience Bachelor’s degree in Computer Science, Software Engineering, or a related field. 5+ years of QA experience on modern, cloud-based platforms. (Preferably GCP) Technical Skills Hands-on experience with: Playwright, Web services and APIs, Node.js-based systems, MongoDB and Postgres Proven experience owning QA processes and test case management. Experience working in Agile/Scrum environments. Strong Jira proficiency for test tracking and defect management. Soft Skills Comfortable being the sole QA owner and setting the quality bar. Confident pushing back on engineering and product when necessary. Able to balance pragmatism with high quality standards. Clear communicator who can articulate risk, tradeoffs, and priorities. Experience mentoring or managing QA engineers is a strong plus. Preferred Qualifications Experience testing AI- or ML-driven workflows. Familiarity with design collaboration tools such as Figma. Experience scaling QA practices from early-stage to mature teams. Prior experience in a QA lead or manager role.
