About the Job

Requirements

  • Have 5–8+ years of experience in material planning, program management, or supply chain roles supporting complex hardware, with hands-on ownership of large, multi-hundred-line bills of materials from development through ramp.
  • Have strong working knowledge of demand/supply planning, supplier readiness, and the cost and material impact of quality and engineering changes.
  • Have experience standing up planning or supply-readiness processes from scratch, rather than only operating within systems built by others.
  • Have a track record of identifying problems weeks before they occur and driving resolution across engineering, sourcing, and manufacturing teams.
  • Be comfortable with ambiguity and interested in shaping how a fast-growing hardware company plans and scales.
  • Have a Bachelor of Science in Supply Chain, Data Analytics, or a related field.

Responsibilities

  • Own end-to-end material planning across bills of materials, including demand/supply reconciliation, buffer and safety-stock strategy, and purchase prioritization that keeps pace with engineering changes.
  • Translate program schedules into current material plans and maintain visibility into what is on track, at risk, and needs to move.
  • Continuously monitor supplier lead times, minimum order quantities, allocation, and other risks.
  • Partner with global supply managers and supplier industrial engineers to close gaps before they threaten a build.
  • Track program-level clear-to-build status and drive cross-functional work to unblock issues before they become hard stops.
  • Own the material and inventory impact of supply-impacting engineering change orders from assessment through implementation, quantify exposure, and keep the program informed of what is changing and why it matters.
  • Work with the software team to build planning tools, dashboards, and processes spanning product lifecycle management, enterprise resource planning, and material requirements planning, creating a shared, trustworthy view of material readiness for Supply Chain, Engineering, and Manufacturing.
  • Design planning systems and processes for the scaling business, not only for the immediate build.

About the Company

Amperesand

Modular solid-state transformers for grid power

Amperesand develops modular solid-state transformers (SSTs) for grid infrastructure using silicon carbide (SiC) devices and proprietary high-frequency transformers. The SSTs are digitally controlled and bidirectional, offered in 2, 4, and 6 MW modules that can be combined to meet larger needs, replacing traditional transformers, switchgear, and UPS in a single AI-driven system. It differentiates itself through the combination of SiC SSTs, proprietary high-frequency transformers, digital power management, and leadership from NTU R&D spun out with Temasek’s Xora Innovation, plus an experienced team from ABB, GE, Siemens, and Vestas. The goal is to speed up the energy transition by delivering scalable, compact SST systems for EV charging networks, microgrids, data centers, and industrial power, with first deliveries planned for 2025 in the US and Singapore.
