Strategic Sourcing Specialist

IONATE is a deep tech scale-up building the hardware and software backbone for smart grids. Our mission is to transform power systems - from grids and microgrids to renewables and data centres - unlocking the massive potential in this under-innovated sector that touches every aspect of our modern lives.

We are looking for a Strategic Sourcing Specialist to join our Operations team and build a resilient, commercially competitive supply base as the Hybrid Intelligent Transformer (HIT) progresses from engineering builds to low-volume UK manufacture and scaled contract manufacturing. You will lead direct-material sourcing strategy, component requirements and order recommendations, commercial supplier selection and contracting, product cost and supply-risk mitigation.

During pilot builds and the pre-production ramp, you will also manage day-to-day material planning and purchasing; these activities will transfer to dedicated resources as the operation grows. Working across Engineering, Manufacturing, Quality and Finance, you will engage suppliers directly, resolve urgent sourcing gaps and complete detailed commercial work as well as develop category strategies. Engineering will retain authority for product design and BOM revisions, while you will manage the commercial and supply implications of approved changes.

What you will do:

• Build direct-material sourcing strategies. Own category and supplier strategies for critical components, assemblies, tooling and production equipment, using product roadmaps, approved bills of materials, demand scenarios and make-or-buy decisions.
• Translate demand into material requirements. Translate approved unit demand and BOM revisions into dated component requirements, shortages and order recommendations. During pilot builds and the pre-production ramp, maintain the material plan, purchase-order coverage, supplier acknowledgements, confirmed delivery dates, shortage status and kit readiness.
• Find and qualify the right suppliers. Map capable suppliers, issue requests for information and quotation, lead commercial due diligence, and coordinate the technical, quality and manufacturing assessments and approvals required before supplier onboarding.
• Run robust supplier selection. Lead competitive supplier selection by creating comparable bid packs, clarifying specifications and assumptions, evaluating total cost, capacity, lead time, quality, resilience and scalability, and documenting commercial recommendations and approvals.
• Negotiate commercial agreements. Secure competitive pricing, minimum order quantities, lead times, payment terms, capacity commitments, tooling ownership, warranties, change-notification rights, intellectual-property protections, liability provisions and appropriate delivery terms.
• Establish transparent product cost. Own the costed bill of materials, should-cost and total-cost models, supplier cost challenges, value-engineering opportunities and the cost-down roadmap linked to volume and design maturity.
• Manage pilot-build purchasing and supply. Work across Engineering and Operations to close specification gaps, convert approved material requirements into purchase orders, place approved orders, obtain supplier acknowledgements, expedite constrained items and resolve supplier issues that threaten pilot and low-volume build dates.
• Manage supply-chain risk and resilience. Identify sole-source exposure, long lead times, obsolescence, financial weakness, geopolitical risk, constrained capacity and logistics dependencies. Develop proportionate mitigation, dual-source and recovery plans.
• Establish supplier and purchasing governance. Own supplier onboarding, approved-supplier records, contract documentation, commercial master data and purchasing controls. Maintain clear performance and shortage reporting, and establish the planning data, buying controls and working methods needed to transfer day-to-day planning and purchasing to dedicated resources as volumes increase.
• Own commercial manufacturing-partner work. Define responsibility boundaries, preserve commercial leverage and supply continuity, and establish the scalable sourcing model for a future Tier 1 partner in North America.
