Senior Software Engineer (m/w/d)

Role brief

Work Location: Stuttgart / remote Your Mission At Conceptboard, we build a collaboration product that enterprise and security-critical teams use daily – and we build it with the commitment that it remains reliable, maintainable, and scalable. For this, we need Senior Engineers who not only deliver, but raise the bar through the way they build. You work hands-on in the Platform or App team, you ship – and you make the team better by doing it. You bring senior delivery capacity where the bottleneck is today, translate the target architecture into real software, and provide feedback when it meets reality. At the same time, you actively ensure that knowledge stays and spreads within the team – you won't be the next single point of failure. Your Responsibilities Build at a high level. You deliver platform and app services hands-on – with the practices that keep them maintainable long-term: testing, observability, clear boundaries, good documentation. Implement and pressure-test architecture. You translate the target architecture into working software. Where it meets reality and breaks, you surface it and feed it back. You influence direction by building. Actively reduce bus factor. You share context, document, pair, and mentor – so knowledge distributes across the team. Explicitly: don't become the next person everything depends on. Set standards through example. Your code review, your craft, your collaboration – that's the level others orient themselves by. Multiply agentic practices. We're establishing agentic engineering across the entire organization. You're convinced of it, live it, and help us set and maintain shared practices. Your Profile Must-haves Strong hands-on engineering skills. Deep, current build experience. The type of senior whose code others trust and can learn from. Sound engineering practices as default. Testing, observability, CI/CD, and clear boundaries are not afterthoughts for you – they're how you work. Collaborative multiplier, not lone hero. You spread knowledge and elevate the team – instead of hoarding context or building dependencies. Agentic-first. You already work agentic-first – or you're eager to learn it and bring the discipline to do it cleanly. Strongly preferred Relevant domain depth: distributed systems, real-time architecture, or collaboration platforms. Experience in highly regulated environments with high compliance requirements. Experience on a platform or enabling team that serves other teams as internal customers. A genuine mentoring track record – not just "occasionally helped." What awaits you with us Flexibility – Enjoy comprehensive freedom regarding your work location and shape your working hours according to your needs. Ownership – You have the opportunity to work independently and take responsibility, supported by a flat hierarchy and short decision-making paths. Internationality – We work in a global team that values and promotes cultural diversity. Our international network enables you to make contacts worldwide. Team spirit – We know how important in-person meetings are to strengthen team spirit. That's why we organize regular social events. Competitive compensation – You receive an attractive salary package and 30 days of vacation per year. Employee benefits – Take advantage of a variety of discounts through our external corporate benefits partner. Find more English Speaking Jobs in Germany on Arbeitnow [Auto-translated from German]
