Mainspring Energy is revolutionizing power generation with its innovative Mainspring Linear Generator technology. The Senior Staff Commodity Manager will lead sourcing for electrical components and systems, focusing on developing a compliant supply chain and collaborating with engineering teams to support product development.
Responsibilities:
- Lead rapid-turnaround sourcing for R&D electrical builds: prototype PCBAs, connectors, cables, sensors, power distribution components, and electromechanical box assemblies
- Identify, evaluate, and onboard new contract manufacturers for electrical assemblies with US and Mexico manufacturing presence (USMCA-compliant)
- Own the sourcing strategy for Mainspring’s AC-to-DC product transition, including BOM-level lead time analysis, risk buy decisions, and production readiness accountability
- Source and evaluate power conversion equipment (inverters, transformers, skidded systems) across multiple suppliers to reduce single-source risk
- Develop and execute a multi-path battery and BMS sourcing strategy compliant with FEOC and IRA (Inflation Reduction Act) requirements, evaluating multiple chemistries and form factors from non-restricted geographies
- Qualify non-FEOC BMS design partners and battery cell/pack suppliers, managing the full cycle from NDA through spec distribution, quote evaluation, and development contract negotiation
- Collaborate with Engineering on DFM reviews, connector and material strategy, corrosion protection solutions, and cable redesign opportunities
- Drive supplier selection committee processes, presenting sourcing recommendations to leadership with clear trade-offs on cost, risk, and schedule
- Negotiate pricing and contracts from R&D quick-turn purchases through long-term volume agreements
- Monitor FEOC, IRA/ITC, USMCA, and tariff developments to proactively adjust sourcing strategies
Requirements:
- Bachelor's degree or higher in Electrical Engineering, Supply Chain, or equivalent technical discipline
- 18+ years of combined experience across electrical engineering, operations, and supply chain roles, with hands-on involvement in sourcing, BOM optimization, and supplier management for electrical and electronics commodities. Experience supporting R&D and new product introduction required
- Deep technical knowledge of power electronics, industrial electrical components, PCBAs (SMT/through-hole/mixed), connectors, cable assemblies, and battery/energy storage systems. Hands-on circuit design, power supply design, or PCBA layout experience is a strong plus
- Experience evaluating and onboarding contract manufacturers for electromechanical assemblies
- Experience managing global manufacturing partners, negotiating contracts, and optimizing bills of materials for cost, quality, lead time, and regulatory compliance
- Comfort operating in fast-paced R&D environments with shifting requirements and close engineering collaboration
- Ability to navigate compliance-driven sourcing environments, including familiarity with regulatory frameworks such as FEOC, IRA/ITC, USMCA, or UL/IEC certification
- Strong negotiation, supplier qualification, and analytical skills
- Willingness to travel up to 40% (domestic US and Mexico; occasional international)
- Experience in energy storage, battery, or distributed power generation
- Working knowledge of IRA battery sourcing requirements and FEOC country-of-origin tracing
- Familiarity with UL 9540, UL 1973, UL 508a, IEC 62619, or related safety certification frameworks
- Prior experience in a hardware startup or high-growth manufacturing environment
- Experience with US and Mexico manufacturing footprints (USMCA)
