We are looking for a Senior QA Engineer to lead the validation strategy, testing execution, and automation efforts for complex, high-impact software systems. This role operates at the intersection of engineering, tools, and product delivery, ensuring that multi-component systems meet the highest standards of quality, performance, and reliability. The ideal candidate is both a technical leader and a quality champion who thrives in complex environments, excels at identifying risk, and drives scalable testing solutions through automation and AI-assisted approaches Expectation, but not limited to: • Leads validation for complex systems spanning multiple components and teams, defining test strategy that covers functional, regression, performance, and reliability risks. Prevents high-impact regressions through proactive planning and deep technical triage. • Creates robust automation and test utilities that materially improve signal quality (reduced flakiness, faster triage, better coverage). Serves as a subject-matter expert who elevates team execution and release confidence. • Utilizes AI to create automated test cases, improve current process and level up test quality. Responsibilities will include, but not be limited to: • Owns large feature areas or subsystems spanning multiple components, including complex interactions across runtime, tools, data, and rendering. Leads cross-team testing efforts and coordinates quality activities for major deliveries. • Defines validation strategy for complex changes, including automation approach, performance considerations, and fidelity checks. Acts as a technical point of contact for quality risk and testability discussions. • Own large feature areas or subsystems that span multiple components across Aechelon products, including complex interactions involving runtime, tools, data, and rendering. • Leads validation for complex systems spanning multiple components or subsystems, coordinating quality activities across ownership boundaries. • Define and drive validation strategies for complex or high-risk changes, including test scope, automation approach, performance considerations, and fidelity or correctness checks. • Serve as the primary technical point of contact for quality risk assessment, testability discussions, and release readiness for owned areas. • Provide technical guidance and mentorship to junior QA engineers, reviewing test plans, test cases, and automation contributions to ensure consistency, coverage, and effectiveness. • Identify gaps in coverage, tooling, or process, and influence improvements that scale quality across teams and releases. • Focus on Tool Development & AI: • Define and drive validation strategies for complex or high-risk changes, with a strong emphasis on Python-based tool development, including test frameworks, utilities, and data-driven validation. • Design, implement, and maintain tool and testing technology in Python that replace or significantly reduce manual testing for QA owned areas. • Utilize AI assisted tools to improve/enhance the automation and day-to-day works.
