About the role

Key responsibilities & impact

Project management: Lead projects from contract signature to commissioning — monitor schedule, quality and costs; act as the central point of contact for the customer.

Actively manage questions from the grid operator; consolidate technical response packages.
Accompany proof and documentation according to relevant standards (e.g., VDE-AR-N 4105/4110) together with partners.

Risks & customer experience: Identify technical risks early, give clear go/no-go signals and find pragmatic solutions.
Inform customers transparently — your goal: turn projects into reference customers.
Build processes: Convert project experience into CRM entries, checklists, templates and simple standards that make future projects faster.
