Senior Software Engineer (m/f/d): AI-Native Development

Job Description We protect our customers’ digital infrastructure, keeping it secure, fast, and online, even under active attack. As a cybersecurity provider, we run high-performance systems in a genuinely hostile environment, where code quality, security, and rigorous input validation are not hygiene: they are the product. Our customers trust us with business-critical traffic, and we build and operate to the highest standards of certification for critical infrastructure.

As a Senior Software Engineer (m/f/d), you will help your team design and build robust solutions for complex problems. We are looking for someone who thinks in systems, who starts from the problem, reasons about the trade-offs of the environment it will run in, and reaches for the tool that fits, rather than the one on their CV. We are constantly improving our applications and we work AI-natively: AI coding agents are part of how we spec, build, and review every day.
