Chapter Lead AI Engineering (f/m/d)

We're digitizing the construction industry – are you in? At VESTIGAS, you build the digital backbone of the construction supply chain. We turn purchase orders, delivery notes, and invoices into a digital, legally compliant platform used in everyday operations by construction companies and suppliers.

Your Role As Chapter Lead AI Engineering, you'll own the AI infrastructure and capabilities that power our supply chain platform end to end – from pipeline design to production deployment. You bring experience in technical leadership and take responsibility for the AI engineering chapter across Scrum teams, shaping architecture, aligning technical standards, and enabling engineers to build dependable AI systems.
