You develop and manage central success metrics for partner evaluation, guaranteeing an excellent customer experience through continuous KPI monitoring of installation quality and reliability.
You scale and optimize operational processes in close collaboration with the tech team by identifying opportunities for digitalization and automation and increasing the efficiency of procurement steps.

You have solid experience in project costing, procurement of technical services or tender management, ideally in the HVAC/plumbing & heating (SHK), construction or energy sector.
You are comfortable negotiating on equal terms with craft businesses and possess the assertiveness needed to drive commercial discussions to a goal-oriented close.
You understand the offer and decision-making logic of installation companies and can accurately assess project risks and realistic margins.
You combine strong numerical affinity with technical understanding of heat pump and PV systems in order to provide well-founded counterarguments.
You act with a strong ownership mentality and feel personally responsible for achieving project margins and the ramp-up plan.
Ideally you have a background as a certified HVAC master technician (SHK), engineer or business economist with a strong technical focus and experience in dynamic platform models.
