Do you have a strong background in quality assurance, a structured approach to testing, and want to join one of the largest technology companies in the Nordics? Then this is the role for you.

In this role, you will work in close collaboration with product, engineering, and design teams, ensuring high quality, reliability, and scalability of backend services in a modern cloud-based environment.

When joining Tieto Tech Consulting as a Quality Assurance Engineer, you will

• Partner with product, engineering, and design teams to refine user stories, ensuring acceptance criteria are clear, complete, and testable.

• Conduct daily evaluations of the QA swimlane in JIRA for new feature work and collaborate with engineers to execute test cycles.

• Design, develop, and document comprehensive test plans and test cases for new and existing backend services.

• Develop and maintain Postman API tests and automated integration test suites targeting backend services and data flows across AWS components (SQS, SNS, DynamoDB, EventBridge).

• Implement and manage API contract testing to validate integrations and ensure data consistency across internal and external services.

• Design, execute, and maintain performance, load, and stress tests for critical backend infrastructure to ensure scalability and reliability.

• Collaborate with engineering teams to define and test security, access control, and compliance requirements (e.g. HIPAA) for backend services handling sensitive data.

• Integrate automated test suites into CI/CD pipelines (GitHub Actions) to establish continuous quality gates and support safe, frequent deployments.

• Manage initial release completion, acting as the first quality gate by approving tickets when testing passes or returning them for rework when defects are identified.

• Collaborate with QA Engineers across squads to ensure a consistent and high-quality experience for both patient- and provider-facing features.

Who we are looking for

• Experienced QA professional with 5+ years of experience in startup or fast-paced environments, combining strong manual testing skills with automated testing capabilities.

• At least 3 years of hands-on experience testing AWS-based backend architectures using Kubernetes.

• Strong understanding of testing patterns for distributed systems and AWS services such as SQS, SNS, DynamoDB, and EventBridge.

• Proficiency in a modern programming language such as Python, Java, or TypeScript for writing and maintaining automated test suites.

• Proven experience designing and implementing automated integration, end-to-end, and component tests.

• Experience with performance, load, and stress testing applied to backend infrastructure.

• Hands-on experience with API contract testing frameworks.

• Working knowledge of CI/CD principles and experience integrating automated tests into deployment pipelines.

• Familiarity with agile development practices and bug tracking tools (e.g. JIRA, BrowserStack).

• Strong analytical mindset with a continuous improvement approach.

• Detail-oriented in test execution and thorough in documentation.

• Strong communication skills and ability to collaborate effectively within cross-functional teams.

Experience in the healthcare domain is considered an advantage.
