• AI and agentic engineering: You evaluate where AI adds user value, prototype responsibly, and help operationalize agentic workflows such as automation, decision support, and developer productivity.
• Cross functional delivery: You partner with Product Managers and stakeholders to build user focused functionality and iterate based on feedback and outcomes.
• Team enablement: You share knowledge, mentor engineers when needed, and contribute to a high performing team through better tools and processes.
• Work setup: You work remote within Germany, with the option to work from our offices in Düsseldorf or Berlin.

• AI systems integration: You have experience integrating backend systems with AI services in production and you understand reliability and risk tradeoffs.
• AI coding tools: You are fluent with AI coding tools such as Claude Code, Cursor, or similar, and you use them to increase delivery speed without compromising quality.
• Product mindset: You care about why you build something and you aim for user value, not output.

• Collaboration: You communicate clearly, work well in cross functional teams, and you enjoy sharing knowledge.
• Languages: You are fluent in English at C1 or C2 level, and you ideally speak German at B2 level or higher.
