QA Engineering in Testing

Hourly Rate: $40-$50/hour
Type: Long Term Contract
We are seeking a QA Engineer to join our growing Quality Center of Excellence and support one of our core release trains delivering software that powers medical diagnostics. This is a high-visibility role backfilling a senior team member and contributing to a complex ecosystem that spans core platform software, hardware integrations, and imaging applications.
The ideal candidate is a confident, vocal quality advocate who thrives in a Scaled Agile (SAFe) environment, engages early in the development lifecycle, and actively shapes acceptance criteria alongside developers and product owners. You will be a key voice at the table - anticipating failure modes, asking the hard "what if" questions, and helping the team ship reliable, well-tested software on aggressive timelines.
Shift-Left Quality & Agile Collaboration
Actively participate in the Three Amigos process (developer, product owner, QA) to review user stories and co-author clear, testable acceptance criteria before development begins
Identify risks, edge cases, and failure modes early - think through what could go wrong (system dependencies, integration failures, data integrity issues) and build test coverage accordingly
Participate fully in SAFe ceremonies, including PI Planning, iteration planning, stand-ups, system demos, and retrospectives
Serve as a strong quality voice within the release train, influencing decisions and raising concerns constructively
Design, document, and execute functional, regression, integration, and end-to-end test cases
Perform manual, exploratory, and API-level testing across a complex, multi-system environment
Validate end-to-end workflows - how orders are placed, processed, resulted, and displayed downstream
Complex System Testing
Test software that interacts with physical diagnostic hardware, imaging systems, and backend data services
Understand and validate integrations, data flows, and dependencies across multiple systems
Perform data validation using SQL and other tools to confirm system behavior end-to-end
Document, track, and triage defects in Jira (or equivalent), providing clear reproduction steps and business impact
Communicate status, risks, and quality metrics clearly to product owners, Scrum Masters, and engineering leadership
Contribute to the build-out of the Quality Center of Excellence - test standards, reusable assets, and best practices
3-5 years of professional QA experience in an agile software development environment

• Demonstrated experience operating in SAFe (Scaled Agile Framework) - PI Planning, ART ceremonies, feature/story breakdown
• Experience working in complex, multi-system environments (integrated hardware/software, healthcare, diagnostics, imaging, or similarly regulated or technical domains is a plus)
• Bachelor's degree in Computer Science, Information Systems, a related technical field, or equivalent practical experience

Experience co-authoring acceptance criteria and participating in Three Amigos or similar shift-left practices
Proficiency with test case management and defect tracking tools (Jira, Azure DevOps, TestRail, Zephyr, or similar)
Solid working knowledge of SQL for data validation
Experience with API testing (Postman, REST Assured, or similar)
Exposure to test automation tools (Selenium, Cypress, Playwright, or similar) and CI/CD pipelines (Jenkins, GitLab)
Familiarity with a scripting or programming language (Java, Python, JavaScript, or C#)
Agile and flexible mindset - open to evolving processes, tools, and priorities
willing to jump in where the release train needs help
Comfortable operating on tight delivery timelines without sacrificing quality
Experience in healthcare, veterinary, medical device, diagnostics, or imaging software
