About the Role

We are looking for a Senior Technical Test Engineer to work onsite in Copenhagen, joining a large‑scale, business‑critical development programme within the public sector. You will play a key role in ensuring quality, stability, and reliability across releases in a complex system landscape. This is a hands‑on role where you will work closely with developers and stakeholders in an agile setup.

The role combines technical test automation, test architecture, and a cross‑functional role in supporting team processes and delivery flow.

Responsibilities

• Develop and maintain automated regression tests to ensure stability across releases.
• Design and evolve scalable test architecture (e.g. Page Object Model and structured test frameworks).
• Contribute to and improve test orchestration and automation setups (e.g. smoke and regression testing).
• Design, implement, and execute test cases for user stories, ensuring Definition of Done is met.
• Perform functional, integration, component, and user acceptance testing.
• Validate that solutions meet acceptance criteria and quality standards.
• Participate in backlog refinement, including user stories, enablers, and defect handling.
• Collaborate closely with developers to ensure built‑in quality.
• Support planning, prioritisation, and delivery flow in the team.
• Contribute to agile ceremonies (e.g. sprint planning, PI planning).
• Help establish and maintain test environments in collaboration with test management.
• Ensure reliable test data and environments.
• Integrate testing into CI/CD pipelines and support continuous delivery.
• Contribute to improving overall test strategy and quality practices.

Qualifications

• Solid experience as a technical tester in larger agile development programmes.
• Experience working in Scrum and/or SAFe environments.
• Strong experience with test automation and regression testing.
• Experience with API testing and relevant tools (e.g. Postman, Selenium or similar).
• Experience with CI/CD pipelines and integrating testing into development workflows.
• Understanding of test architecture and scalable test design.
• Experience with Test Driven Development (TDD) or similar practices.
• Comfortable working closely with developers in a full‑stack team.
• Comfortable taking a cross‑functional role supporting both testing and team processes.
• Fluency in written as well as spoken Danish is required.

Preferred

• Experience teaching or mentoring others in testing practices.
• Experience with test orchestration frameworks.
• Experience in large public sector programmes or regulated environments.
• Experience with AI‑assisted testing or modern testing tools.

About You

• Detail‑oriented and quality‑focused.
• Take ownership of testing and quality assurance.
• Collaborative and thrive in agile teams.
• Proactive and able to identify and solve issues early.

What We Offer

• Opportunity to work on large‑scale, business‑critical systems.
• A central role in ensuring quality and stability in complex solutions.
• Opportunities for learning, certification, and professional development.
• A strong technical environment with knowledge sharing and collaboration.
• A comprehensive employee package including pension, health insurance, and additional benefits.
