5+ years experience in software quality assurance, including ownership of test strategy and automation architecture for complex software products.
Hands-on proficiency with modern end-to-end automation frameworks such as Cypress, Playwright, or equivalent tools, plus scripting experience in TypeScript, Python, or C#.
Experience configuring or using CI/CD pipelines such as TeamCity, Jenkins, or GitHub Actions to support quality gates, build health monitoring, and pipeline reliability.
Advanced experience using Jira for defect lifecycle management, test planning, sprint reporting, and cross-team quality visibility.

Travel, Motor Vehicle Record & Physical/Environment Requirements:

Ability to work in an office and laboratory/instrument environment as needed to support software verification and instrument-software integration testing.
Occasional travel may be required for cross-site collaboration, product validation, or team/customer engagement; specific travel requirements to be confirmed by the hiring manager.

It would be a plus if you also possess previous experience in:

HCS.ai, IN Carta®, or similar high-content imaging and analysis software platforms in a life science or laboratory automation environment.
Hardware-software integration testing for lab instrument systems such as imaging platforms, automated liquid handlers, or robotic workflows.
Professional use of AI-assisted development tools such as GitHub Copilot for test script generation, refactoring, migration support, or coverage gap analysis.
