Your role in the team

  • Want to do more than just find bugs? Do you enjoy getting to grips with complex processes while keeping users in mind? Then bring your experience to our foerderplan.web team.
  • With us, you’ll work independently, but never alone: Together with colleagues from Quality Assurance, Product Management, and Development, you’ll ensure the technical quality of our software—with users always in mind.
  • Your focus is on manual functional testing. You’ll work with us to develop a reliable testing framework and, as your product knowledge grows, contribute to user support and product documentation.
  • Challenge requirements and make them testable: You bring a testing perspective to software development early on and support specifications, requirements documentation, and verifiable acceptance criteria. You clarify open questions with Product Management and Development and help formulate verifiable acceptance criteria.
  • Independently develop and execute tests: You derive test scenarios, test cases, and suitable test data from requirements and business processes. You perform manual functional, system, and regression testing—including error, special, and boundary cases.
  • Make errors traceable and track them: You document test results and describe errors so they can be reproduced and addressed effectively. You assess their impact on the business, support the resolution process, and verify fixes.
  • Develop our testing structure: Together with the team, you build and maintain a reusable test case library and develop shared testing standards. You make test coverage and remaining risks transparent and set risk-based testing priorities. When needed, you help select and introduce suitable testing tools and support UI/UX testing.
  • Apply your application expertise in specialist user support: After your onboarding, you will handle subject-matter inquiries, reproduce application scenarios, and distinguish between usage questions, unclear requirements, and software bugs. You will explain solutions clearly and use your findings to support testing and product improvements.
  • Keep documentation clear and up to date: You support the maintenance of product documentation and user manuals. You ensure descriptions are easy to understand, up to date, and reflect the software’s actual behavior, helping our users in their day-to-day work.

Our expectations of you

Education

  • You have completed vocational training or a degree and have at least three years of professional experience in software testing / functional quality assurance. You want to continue designing and carrying out tests yourself.

Qualifications

  • You hold the ISTQB CTFL certification and confidently apply testing methods—from test case design and test data to regression testing and the systematic testing of error and boundary cases.
  • You structure your tasks, prioritize them transparently, and consistently follow up on outstanding items. You’re open to feedback, enjoy learning, and share your knowledge with the team.
  • You explain and document technical concepts, error patterns, and solutions clearly and precisely for Product Management, Engineering, and customers. Your German language skills are at least C1 level, both spoken and written.
  • You are interested in the digitalization of administrative processes.
  • You can regularly work on-site at our Düsseldorf location.

Experience

  • You analyze complex, rule-based business processes, identify dependencies, and enjoy getting to grips with administrative topics. You understand technical concepts such as user roles, permissions, and test environments. Experience with administrative software is a plus, but not a requirement.
