About this role
Job description We are modernizing a business-critical Payroll platform and building the foundation for a more scalable, service-oriented and AI-enabled product. This is a <strong>software engineering role, not an AI/ML engineering role</strong>.<br><br>We are looking for experienced engineers who are strong in backend and platform development and who already work, or want to work, in an <strong>AI-first engineering environment</strong>.<br><br>AI-assisted development is part of the normal engineering workflow: understanding existing systems, exploring solutions, writing and reviewing code, creating tests, documenting decisions and accelerating delivery. You will work on gradually transforming an established, business-critical product without disrupting the proven Payroll logic behind it. Your tasks <ul><li>Design and build modern backend services and platform capabilities around an established Payroll product</li><li>Build APIs and integration points that allow Payroll capabilities to be used by modern applications and workflows</li><li>Modernize the product incrementally rather than through a big-bang rewrite</li><li>Work closely with existing engineers and Payroll domain experts to understand and safely evolve proven business logic </li><li>Establish strong engineering practices around automated testing, observability, code quality and maintainability </li><li>Use AI throughout the software development lifecycle to: <ul><li>understand unfamiliar and complex codebases </li><li>analyse dependencies and behaviour </li><li>explore solution options </li><li>accelerate implementation </li><li>generate and improve tests</li><li>review code and documentation</li></ul></li><li>Help define how AI-first software engineering should work in practice across the team</li><li>Collaborate with external Web/UI engineers while ensuring that core product architecture and engineering quality remain owned internally </li><li>Contribute to technical architecture and modernization decisions</li></ul> Your profile <ul><li>Several years of professional software engineering experience with strong backend development skills in a modern programming language and ecosystem</li><li>Experience designing APIs, services and integration-oriented systems, with a solid understanding of software architecture, clean boundaries and maintainable system design</li><li>Comfortable working with existing or complex systems – not only greenfield products – and taking ownership from technical problem through implementation and production</li><li>Strong automated-testing mindset and excellent communication skills, with a willingness to work closely with product and domain experts</li><li>Practical experience using modern AI coding tools or engineering agents as part of day-to-day development, combined with the ability to judge AI-generated output critically</li></ul><br><strong>Particularly valuable</strong><br>Experience in one or more of the following is a plus: modernization of large or long-lived software products, strangler/incremental migration approaches, cloud and container-based environments, asynchronous processing, high-compliance or business-critical software (e.g. Payroll, HR or financial), legacy integration, or developer platforms and internal tooling.<br><br>Experience with C#/.NET, especially for backend services, APIs or modernization of established applications.<br><br>We are not looking for someone whose primary skill is a specific legacy technology, we are looking for engineers who can help us progressively move beyond it. Your benefits <ul><li>Collaboration within an empathetic and supportive team</li><li>You can put your knowledge and personal strengths to good use, and continue to develop your skills and grow</li><li>You’ll start with a structured onboarding process and learn ‘on the job’, through training sessions or informal learning formats and working in interdisciplinary and international teams</li><li>You’ll have the opportunity to benefit from our hybrid work concept, which includes working in the office, from home, on the move and on workations</li><li>A modern tech stack and agile working methods are a given</li><li>A wide range of benefits, e.g. pension scheme, health management – right through to staff discounts</li><li>Well-behaved dogs are very welcome at all our locations</li></ul> I look forward to receiving your application Svenja Krüßel<br>D-49835 Wietmarschen-Lohne<br>Tel.: 0170-7888740<br>E-Mail: <a href="mailto:[email protected]">[email protected]</a>
