Technical Product Manager (Integrations & Connectors)

Cosuno, a fast-growing startup in the construction tech industry. As a Technical Product Manager, you will be responsible for driving the integration of our REST API and connectors into our customers' daily work. You will work closely with engineering, customer success, and sales to create a clear roadmap and launch API improvements. You will also have the opportunity to make a significant impact on our customers' day-to-day operations.

About Cosuno

You keep growing. You actively build your skills, and you seek and act on feedback

You've shaped an API from the product side. You've defined, together with customers and engineering, what a public API or integration of a SaaS product exposes: endpoints, data models, auth, permissions

Responsibilities

• This position offers the flexibility of remote work or working from our Berlin office, flexible working hours, and the chance to participate in company offsites and team events.
• Kunden kennenlernen und deren Bedürfnisse verstehen, um eine klare Roadmap für API-Verbesserungen und Integrationen zu erstellen.
• Die ersten API-Verbesserungen und den ersten MCP-Server starten, Engineering-Tickets schreiben und die Implementierung bei Pilotkunden überwachen.
• Entscheidungen über zukünftige Entwicklungen treffen, basierend auf realen Nutzungsdaten und Pilotfeedback, in Zusammenarbeit mit dem CTO und dem Head of Product.
• You write tickets engineers love. Clear scope, clear acceptance criteria, and a clear line on what's out of scope. You prioritize by impact, not by who shouts loudest
• You live AI. You use LLM assistants and MCPs every day, and you've built your own automations

Requirements

• You find the real need. You've worked directly with customers, separated what they ask for from what they really need, and found what it takes for them to use an integration
• Bonus points if you've helped build an MCP server that customers use, or if you know construction tech, ERP or estimating systems (e.g. RIB iTWO, SAP, Nevaris)
• You're fast. You ship in weeks, not quarters, and you build, learn and iterate in parallel

• You're technical enough to go deep with engineers. Webhooks vs. polling, pagination, rate limits, OAuth: you can discuss trade-offs, and you test APIs yourself
• Based in Germany and open to traveling to customers across the country
• Fluent German and English. Our customers are German construction companies who work in German. Our engineering team works in English
• You explain complex things simply, to a construction company's project manager as well as to internal stakeholders like our commercial teams or our management
