More than 270 agencies in 31 US States, and 3 Canadian Provinces, including 28 state Departments of Transportation, are using MS2 software to manage their transportation data.

MS2 is located in the beautiful city of Ann Arbor, Michigan, the home of high-tech industries and the University of Michigan. Residents of the city enjoy beautiful parks, mature neighborhoods, amenities of the Huron River and easy access to downtown Detroit or to colorful "Pure Michigan" woods and waterways.

MS2 is a friendly, open, team working to support our clients' software needs. Staff members work on a variety of tasks and are given a high degree of responsibility. We offer an excellent environment for transportation professionals and Software Engineers with competitive compensation and benefit packages. We're a small team and you'll have an opportunity to make a big impact!

We are seeking a Senior Quality Assurance Engineer to help design, build, and maintain the core testing systems that ensure MS2's transportation platform meets the highest standards of quality and reliability. You will partner with product and engineering teams to establish and evolve a robust test automation strategy across the full stack, from UI and API testing to integration and data validation. The role emphasizes ownership, technical craftsmanship, and the ability to solve complex quality challenges independently while collaborating with an experienced, supportive team.

Responsibilities:

• Design, build, and maintain automation frameworks and supporting utilities that are reliable, maintainable, and easy for others to contribute to
• Define and prioritize automated coverage across UI, API, and integration layers, balancing speed, stability, and confidence
• Integrate automated tests into CI/CD pipelines and ensure results are fast, trustworthy, and actionable (clear failures, logs/artifacts, and ownership)
• Own the operational health of the automation suite by reducing flaky tests, improving runtime performance, and keeping tests aligned with product changes
• Collaborate closely with product managers and engineers to align on approach and execution
• Establish and maintain test plans for key workflows, including regression and exploratory testing for high-risk changes
• Triage defects efficiently by isolating root causes, providing clear reproduction steps, and collaborating with engineers through resolution and verification
• Provide clear reporting on quality signals (coverage, trends, stability, release readiness) and recommend improvements based on data
• Mentor and enable others to contribute to quality and automation through pairing, documentation, examples, and code review of test changes
  
  

Requirements

• Bachelor's degree in computer science, engineering, or equivalent practical experience
• 6+ years of experience in software quality assurance, with significant ownership of automation in production environments
• Proven experience designing and maintaining automation frameworks and test infrastructure (not only writing individual tests)
• Proficiency in at least one programming language used for test automation (strong preference for C# or JavaScript/TypeScript)
• Strong understanding of QA methodologies, defect triage, and building reliable quality signals throughout the SDLC
• Experience testing systems with large datasets and complex workflows
• Experience integrating automated tests into CI/CD and maintaining high-signal pipelines (debuggability, artifacts, stability)
• Strong communication skills and ability to collaborate cross-functionally with engineering and product stakeholders
