About the role

The Senior Software Engineer, Test Automation is responsible for designing, implementing, and maintaining automated tests and test infrastructure for high-content imaging software. This role collaborates with software development, quality assurance, product ownership, and engineering leadership teams to improve automated coverage, integrate end-to-end workflows between products, monitor continuous integration pipelines, and provide clear, timely information about software build quality and release readiness. This is a 100% on-site role located in Downingtown, PA.

Responsibilities

• Automated Test Development: Design, implement, debug, and maintain reliable automated end-to-end and integration tests for complex imaging software using Cypress and related testing technologies.
• Cross-Product Test Architecture: Collaborate with software development and quality assurance teams to develop reusable test frameworks and automate workflows that span multiple products, services, and instrument-control applications.
• CI/CD, Build Quality, and Root-Cause Analysis: Monitor automated test pipelines and software builds daily; investigate complex or intermittent failures using evidence from multiple sources; distinguish product defects from test or infrastructure issues; communicate which builds are suitable for further verification and validation; and improve test reliability, diagnostics, processes, and infrastructure to prevent recurrence.
• Test Strategy and Coverage: Translate product risks, customer workflows, and acceptance criteria into automated test designs and backlog stories; identify gaps in regression coverage and prioritize automation that delivers the greatest quality and business impact.
• Technical Leadership and Collaboration: Work independently with product owners, software leads, quality assurance engineers, engineering managers, and developers; lead focused automation initiatives, build consensus on quality issues, and serve as a technical resource for colleagues with less automation experience.

Requirements

• Education and experience: Bachelor's degree in Computer Science, Software Engineering, or a related discipline with 5+ years of professional software development or software test automation experience; equivalent directly relevant experience may be considered.
• Test automation expertise: Demonstrated experience designing and maintaining automated end-to-end or integration tests for commercial software, including practical expertise with Cypress or a comparable browser automation framework and JavaScript or TypeScript.
• Continuous integration: Experience integrating automated tests into CI/CD pipelines, monitoring pipeline and build health, diagnosing failures, and communicating actionable quality and release-readiness information.
• Software engineering practices: Proficiency with Git, package-management and build tools such as npm, REST-based applications, test design patterns, defect tracking, and Agile development practices.
• Independent problem solving and collaboration: Ability to solve complex technical problems with minimal guidance, perform effective root-cause analysis, lead small initiatives, explain difficult technical information clearly, and build consensus across cross-functional teams.

Preferred Qualifications

• Scientific or instrument-control software: Testing laboratory instruments, imaging systems, robotic systems, or other software connected to physical hardware.
• High-content imaging: Familiarity with microscopy, image acquisition and analysis workflows, or life science applications.
• Cross-product automation: Building automated workflows that coordinate multiple desktop applications, browser applications, backend services, or independently released products.
• Additional test technologies: Experience with Angular application testing, API testing, Windows desktop automation, test reporting systems, or improving the reliability and observability of large regression suites.
