Senior IT Security Manager

Technical Product Manager

• Take ownership of our integrations product area — the REST API and our existing connectors to third-party systems such as RIB iTWO — and define where they go next.
• Travel to customers across Germany to support them hands-on with implementing and setting up connectors, and to understand their systems, data flows, and constraints in the real world.
• Sit down with customers to elicit integration requirements, then prioritize them against impact, effort, and our platform strategy.
• Translate those requirements into clear, well-scoped tickets that our engineers can pick up and build — with the technical context they need to move fast.
• Work through our API documentation and test endpoints yourself to validate what's possible, spot gaps, and represent the developer experience from the outside in.
• Partner with Engineering, Customer Success, and Sales to make sure customers can connect their systems to Cosuno with as little friction as possible.
