• Develops a deep understanding of product functionality, system architecture, and customer usage patterns to inform testing approaches. • Contributes to test strategy by identifying quality risks, gaps in coverage, and opportunities to improve confidence in releases. • Influences broader testing direction through technical leadership and collaboration rather than ownership of formal approval gates. • Designs, implements, and maintains high-quality automated tests across appropriate layers, including API, integration, and system-level testing. • Continuously evaluates existing test coverage, strengthens weak areas, and reduces redundant or low-value tests. • Executes tests as needed to validate changes and support release readiness. • Builds and maintains reliable, maintainable automated test suites integrated into CI pipelines. • Improves test stability, execution speed, and signal quality to support fast and safe development workflows. • Works closely with engineers to ensure tests run effectively across branches and environments. • Executes existing load and performance tests, reviews and reports results, and maintains the test suite as needed. • Partners with Load and Performance test engineers who own performance test creation and expansion. • Contributes to technical design discussions from a quality and testability perspective. • Dives deep into complex systems to diagnose issues, understand failure modes, and identify root causes. • Proposes pragmatic improvements to architecture, testing approaches, or tooling to reduce long-term quality risk. • Helps define and evolve test and quality metrics that provide meaningful insight into system health and testing effectiveness. • Uses data to guide decisions, prioritize improvements, and surface systemic issues. • Contributes to documentation, runbooks, and best practices that improve team efficiency and consistency. • Works closely with Engineering and Product partners to ensure quality considerations are addressed throughout the development lifecycle. • Influences testing standards, practices, and tooling adoption through example, technical credibility, and constructive collaboration. • Adheres to all confidentiality and compliance regulations. • Performs other duties as assigned.
