Position Summary

The Tester Engineer leads software testing and validation activities for medical device software, ensuring product quality, performance, and regulatory compliance throughout the software development lifecycle. The role combines functional testing, test automation, performance engineering, and verification & validation (V&V) activities while supporting release decisions, risk management, and continuous quality improvement. Working in a highly regulated environment, the Tester Engineer collaborates with cross‑functional teams to deliver safe, reliable, and high‑performing software solutions for cancer care.

Missions

For functional testing & V&V

• Review SRS (Software Requirements Specification) and related V&V documentation with Product Owners and Software Tech Lead
• Design, write, and maintain test plans and test protocols for ART-PLAN (Cloud and On-Premises versions)
• Execute manual functional tests on every candidate release (alpha, beta, RC)
• Collaborate with Product Owners to clarify acceptance criteria and reproduce edge‑case scenarios
• Report, track, and prioritize defects in close collaboration with developers and QA
• Perform full Verification Testing in Phase 4 as defined by IEC 62304
• Validate behaviour on both AWS cloud tenants (eu-west-3, US, UK) and On-Premises deployments, including air-gapped environments
• Deliver the final GO / NO-GO recommendation at each release gate to authorize safe deployment
• Maintain traceability between SRS, test cases, and test execution results for certification audits
• Support regression analysis and impact assessment across releases
• Participate in release readiness reviews and post-release monitoring

For test automation & performance engineering

• Design and maintain the automated E2E test suite (Cypress/Playwright) integrated into the Azure DevOps CI/CD pipeline
• Design, implement, and operate Long Run Tests (24h / 48h / 72h stability runs) to detect memory leaks and performance degradation
• Design and operate Benchmark Tests to monitor computational and throughput trends across releases
• Design and operate Performance Tests (load, stress, capacity) for both Cloud and On-Premises deployments
• Maintain automated test infrastructure, monitor test stability, and triage flaky tests

For all testing activities

• Pilot and mentor one junior Software Tester, including reviewing their test plans and providing technical guidance
• Contribute to the continuous improvement of the QMS testing process (SOPs, templates, metrics)
• Review Software Design documents and participate in Software Design and Planning meetings
• Maintain the testing knowledge base and onboarding documentation for new team members
• Define and track testing KPIs (coverage, defect density, escape rate, MTTR, test execution time)
• Ensure test reporting is compliant with IEC 62304 verification requirements and fully auditable
• Participate in risk analysis activities (ISO 14971) and translate identified risks into adequate test coverage
• Contribute to CAPA investigations related to defects escaped to production
• Interact with Functional Team, Product Owners, and external consultants on testing scope, schedule, and deliverables
• Escalate blockers and GO / NO-GO risks directly to the Engineering Director
• Ensure regulatory compliance with IEC 62304, MDR 2017/745, and IEC 81001-5-1 (where applicable)
• Engineering Degree or equivalent (Computer Science, Software Engineering) — 5+ years of experience in software testing, including at least 2 years in a regulated software environment (medical device, aerospace, automotive, or equivalent)

Required skills

For software testing & V&V

• Experience with test management tools (Azure DevOps Test Plans, Xray, TestRail or equivalent)
• Knowledge of testing methodologies (ISTQB certification appreciated, risk-based testing, exploratory testing)
• Experience testing both Cloud (AWS) and On-Premises software deployments

For test automation & performance

• Experience with E2E automation frameworks (Cypress, Playwright, Selenium or equivalent)

For all testing activities

• Working knowledge of CI/CD pipelines (Azure DevOps, GitLab CI)
• Understanding of regulated software lifecycle (IEC 62304, ISO 13485, MDR); medical imaging and DICOM knowledge is a plus
• Leadership skills — ability to mentor a junior tester and coordinate testing activities
• Critical Thinking
• Communication skills — ability to interface with Product Owners, developers, and senior management
