Test Automation & Quality Engineer – TWINT Team

Role Overview

• Drive test automation across all test levels (unit, integration/API, E2E) with suitable black-box, grey-box and white-box techniques.
• Apply risk-based test design with an automation-first approach, complemented by manual, functional and exploratory testing where needed for feature acceptance and regression testing.
• Design, build, and evolve scalable test frameworks (test data, reporting, parallelization, maintainability, coverage).
• Collaborate closely with software engineers, product owners, stakeholders and Acceptance Testing to embed quality into development.
• Automate and optimise CI/CD pipelines (pipeline-as-code, e.g. GitLab, Jenkins, GoCD) for fast and reliable feedback.
• Improve and streamline testing and deployment processes for faster, more reliable releases.
• Contribute to the centralized automation strategy and align with Acceptance Testing on business-critical scenarios.
• Develop scripts and tools (Python/Bash) to increase efficiency and reduce repetitive manual effort.
• Understand business processes and product behaviour to design meaningful tests and identify quality risks early.
• Support feature verification and acceptance activities through active stakeholder exchange.
• Act as a quality champion within the team and help further develop testing and QA practices.

Requirements

• Good understanding of DevOps practices, modern software delivery and quality engineering.
• Detail-oriented, pragmatic and solution-driven mindset with focus on quality, risk and maintainability.
• Comfortable challenging the status quo and driving improvements in testing and engineering practices.
• Fluent English; German is a plus.
• Strong understanding of black-box, grey-box, white-box, exploratory and risk-based test design.
• Ability to understand business requirements and translate them into automated and manual test scenarios.
• Automation-first mindset with pragmatism to complement automated coverage where needed for feature acceptance and regression testing.
