Senior Automation Tester- 3D Medical Imaging

Merative•Mississauga, ON

16d•$116,509 - $174,763•Remote

About The Position

Merge medical imaging solutions, offered by Merative, combine intelligent, scalable imaging workflow tools with deep and broad expertise to help healthcare organizations improve their confidence in patient outcomes and optimize care delivery. Working under minimal supervision, this position is responsible for executing the test and verification activities for our PACS systems, and for the documentation that evidences them. The role is responsible for testing activities throughout the software development lifecycle, ensuring the quality, reliability, and performance of web-based medical imaging applications. This is an individual-contributor role with no direct reports. Approximately 80% of the role is hands-on testing and verification. The remaining 20% covers test coordination and delivery leadership — assigning and tracking test activities, tracking project work and deliverables, facilitating the team's cadence events, and leading backlog refinement in partnership with the Architect. Influence is exercised through coordination, facilitation, and expertise rather than line authority.

Requirements

Strong understanding of Software Quality Assurance methodologies.
Ability to define test strategies and risk-based testing approaches.
Ability to estimate testing effort and identify quality risks.
Experience with Agile software development, including facilitating team events and backlog refinement.
Ability to coordinate work across a team and hold commitments on track without line authority.
Ability to work independently on large, complex systems.
Strong analytical and problem-solving skills.
Strong attention to detail and commitment to product quality, including the discipline required for documentation in a regulated environment.
Experience testing medical imaging applications, PACS systems, and radiology workflows.
Experience testing 3D medical imaging technologies, including MPR, MIP, and Volume Rendering.
Familiarity with DICOM standards and imaging workflows.
Experience testing web-based applications.
Familiarity with Windows environments.
Experience using defect and backlog management tools such as Jira.
Bachelor's degree in Computer Science, Software Engineering, or a related field, or equivalent experience.
8+ years of software testing and quality assurance experience.
Experience planning, coordinating, and leading testing activities across a team.
Experience creating verification and validation documentation in a regulated software environment.

Nice To Haves

Experience with AI-assisted development and testing tools (e.g., Microsoft Copilot, GitHub Copilot, Claude) preferred but not required.
Experience with FDA, IEC 62304, ISO 13485, or similar regulated development environments preferred.
Experience testing PACS, medical imaging, healthcare software, or 3D imaging applications preferred.
Experience facilitating Agile ceremonies and backlog refinement preferred.

Responsibilities

Author, execute, and maintain test cases and verification protocols.
Verify software functionality against functional requirements, user requirements, and design specifications.
Test web-based applications and imaging workflows, including 3D visualization and advanced rendering workflows.
Assist in testing systems, modules, integrations, and prototypes.
Perform installations, configurations, and execution of verification procedures.
Conduct ongoing regression, integration, and end-to-end testing.
Author and maintain verification and validation documentation supporting regulatory compliance — test plans, protocols, traceability, and summary reports — keeping records current and audit-ready.
Work with development teams to troubleshoot and resolve issues.
Report and track defects using approved defect tracking tools.
Maintain test environments and test data as required.
Define and own the test strategy for the PACS product area, including risk-based coverage decisions.
Plan, assign, and track test activities across the team — including automated test development assigned to engineers — and review the resulting coverage and results.
Set direction for improvements to test coverage, test data, and testing processes, working with engineering to implement them.
Track overall project work and deliverables across the team — coding assignments, test assignments, and documentation — and maintain a current status picture.
Lead backlog refinement in partnership with the Architect, driving story clarity, acceptance criteria, and readiness. The Architect retains ownership of priority and backlog ordering.
Facilitate the team's cadence events — iteration planning, daily sync, review, and retrospective — keeping them crisp, time-boxed, and outcome-focused.
Surface progress, risks, dependencies, and blockers early to the team, the Architect, and management so they can act.
Remove impediments within the team's reach and escalate those beyond it.
Drive corrective and preventive actions from retrospectives, audits, and quality findings through to closure.
Track and report team-level delivery flow and predictability.
