Senior Requirements Engineer

Senior Requirements Engineer The Opportunity If you're a strong software engineer who's grown tired of pure delivery work and wants to get closer to clients, shape solutions from the ground up, and see the direct impact of what you build - this is a role built around exactly that. You'll be advising, designing, and delivering across complex IT projects, with the autonomy to try new approaches and the backing of a team that actually values good engineering. The Role You'll work directly with clients to understand their needs, model requirements, and design solutions that fit their world. That means thinking creatively alongside customers rather than just executing a brief, assessing technical feasibility with software architects, and helping shape the scope of proposals before work even begins. Day-to-day you'll be involved across the full project lifecycle, from early consulting and requirements engineering through to implementation support and ongoing operation. You'll also be integrating AI-supported methods where they genuinely add value, and building the kind of long-term client relationships where success is shared. There's real variety here. Projects are challenging and no two are the same. The Company Our client is a well-regarded business with a strong reputation for technical excellence and a culture that puts quality first. They're flat in structure, open in how they communicate, and serious about giving their people room to grow, whether that's through conference attendance, training, or simply the space to try something new and learn from what happens. The environment is collaborative, solution-focused, and built around people who care about their craft. What You'll Need A degree in computer science or a related field such as physics or mathematics Solid professional experience as a software engineer, ideally with Java or a comparable language Strong grounding in software architectures and development processes Experience in requirements management on software projects A practical, proactive approach to applying AI tools where they genuinely help Very good German and good English The ability to quickly get to grips with a client's world and communicate clearly within it How to Apply Send your CV to the MAM Gruppe team. It doesn't need to be up to date - send what you have, or just get in touch for a conversation.
