• Conduct technical assessments and audits to gather and analyze the information necessary for accurate quotations.

• Develop detailed cost estimates for mechanical parts, subassemblies, and complete systems based on engineering drawings, BOMs, and technical specifications.

• Analyze RFQs from customers and suppliers to identify cost drivers and prepare competitive quotations.

• Build, maintain cost models, and prepare “what-if” analyses for management review.

• Perform design-for-manufacturability (DFM) reviews to ensure cost efficiency and manufacturability.

Coordination & Communication

• Collaborate and coordinate with engineering, supply chain, and production teams to validate manufacturing methods, material selections, and assembly process assumptions.

• Lead meetings and communications related to quotation and pricing discussions.

• Provide pre- and post-sales technical support to internal teams.

• Ensure on-time and accurate responses to all quotation and technical email inquiries.

• Work closely with global teams (factory, sales, and purchasing) to resolve issues and provide coordinated support.

• Collaborate with related departments to gather necessary information and optimize cost proposals, including design guidelines, costing methods, and material cost data.

Reporting & Continuous Improvement

• Prepare summary reports and presentations for executive-level decision-making.

• Support continuous improvement by identifying cost reduction opportunities and manufacturing efficiency enhancements.

• Maintain cost databases and historical data for recurring and similar projects.

• Ensure all cost estimates comply with company standards and customer expectations.

• Perform additional duties as assigned by the reporting manager.

• Bachelor’s degree in Mechanical Engineering, Industrial Engineering, Business, or related field.

• 1–5 years of experience in cost estimation or manufacturing engineering, preferably within semiconductor equipment, precision machining, or contract manufacturing environments.

• Strong technical understanding of CNC machining, sheet metal fabrication, welding, and mechanical assembly processes.

• Expert-level proficiency in Microsoft Excel, including complex formulas, pivot tables, data analysis, and macros.

• Excellent analytical, numerical, and problem-solving skills.

• Able to work independently and manage multiple RFQs or projects under tight deadlines.

• Strong English communication and presentation skills with experience reporting to senior management.

• Familiarity with ERP systems (SAP, Oracle, or equivalent) and cost estimation software is a plus.

Personal Attributes

• Self-driven and accountable with a high attention to detail.

• Strong business acumen and cost awareness.

• Professional, organized, and able to prioritize effectively.

• Comfortable presenting and defending estimates to management and customers.
