- Build senior-level relationships with supplier leadership, and conduct regular factory visits to assess capacity and strategic fit
Market Intelligence & Reporting
- Track raw material and component market trends (cell prices, silicon, copper, freight, FX, etc.) and the evolving Chinese supplier landscape, translating them into pricing and sourcing decisions
- Provide structured, KPI-driven reporting on savings, spend, supplier performance and risk to procurement leadership
- Work closely with Berlin-based Category Management, Product Management and SCM to align on roadmaps, forecasts and priorities
Your profile
- Bachelor's or Master's degree in Engineering, Business, Supply Chain or a related field; an MBA is a plus
- 7+ years of experience in strategic sourcing or category management, ideally in energy storage, power electronics, PV or a comparable technical manufacturing industry
- Proven track record of leading complex negotiations and delivering measurable savings with Chinese suppliers
- Hands-on experience with RFx processes and e-auctions, and with TCO and should-cost modeling
- Sufficient technical understanding of battery systems, inverters or PV modules to engage credibly with supplier engineering teams
