• Consolidate and validate costing, assumptions, and exclusions; support Sales with scenario comparisons, trade‑off analysis, and cost transparency.
• Govern margin protection through consistent costing methodologies, deviation control, and structured approval processes.
• Assess execution feasibility and risks (capacity, lead times, materials, engineering workload), ensuring mitigation actions and policy compliance prior to submission.
• Lead handover from proposal to execution, ensuring assumptions, clarifications, and commitments are clearly transferred to enable smooth manufacturing execution.

What You Bring
