About the 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 software engineering role, not an AI/ML engineering role.
We are looking for experienced engineers who are strong in backend and platform development and who already work, or want to work, in an AI-first engineering environment.
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
* Design and build modern backend services and platform capabilities around an established Payroll product * Build APIs and integration points that allow Payroll capabilities to be used by modern applications and workflows * Modernize the product incrementally rather than through a big-bang rewrite * Work closely with existing engineers and Payroll domain experts to understand and safely evolve proven business logic * Establish strong engineering practices around automated testing, observability, code quality and maintainability * Use AI throughout the software development lifecycle to: * understand unfamiliar and complex codebases * analyse dependencies and behaviour * explore solution options * accelerate implementation * generate and improve tests * review code and documentation * Help define how AI-first software engineering should work in practice across the team * Collaborate with external Web/UI engineers while ensuring that core product architecture and engineering quality remain owned internally * Contribute to technical architecture and modernization decisions
Your profile
* Several years of professional software engineering experience with strong backend development skills in a modern programming language and ecosystem * Experience designing APIs, services and integration-oriented systems, with a solid understanding of software architecture, clean boundaries and maintainable system design * Comfortable working with existing or complex systems – not only greenfield products – and taking ownership from technical problem through implementation and production * Strong automated-testing mindset and excellent communication skills, with a willingness to work closely with product and domain experts * 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
Particularly valuable 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.
Experience with C#/.NET, especially for backend services, APIs or modernization of established applications.
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
* Collaboration within an empathetic and supportive team * You can put your knowledge and personal strengths to good use, and continue to develop your skills and grow * 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 * 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 * A modern tech stack and agile working methods are a given * A wide range of benefits, e.g. pension scheme, health management – right through to staff discounts * Well-behaved dogs are very welcome at all our locations
I look forward to receiving your application
