Tool Development Engineer Jobs (NOW HIRING)

As a member of the Quality Assurance team, the Senior QA SDET will help ensure the quality and reliability of Aechelon's simulation software, tools, and 3D visual database products through system-level testing, automation development, and validation of complex feature sets. In addition, they will participate in the design and implementation of automated test frameworks, test utilities, and validation strategies that improve test coverage, efficiency, and product quality. They will also use existing and future AI-assisted tools to enhance testing processes, generate automated test cases, and support quality initiatives across multiple product teams

• 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.

• 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.
