Job Description

At Thermo Fisher Scientific, you’ll do meaningful work that makes a positive impact on a global scale. Our teams are united by our Mission to enable our customers to make the world healthier, cleaner, and safer. We provide colleagues with opportunities to grow while developing innovative solutions that address complex scientific and manufacturing challenges.

Position Summary

We are seeking a Engineer III – Mechanical to lead should-cost analysis and cost engineering activities across complex mechanical components, assemblies, and products. This role will develop robust, data-driven cost models that improve cost transparency, enable design-to-cost decisions, strengthen supplier negotiations, and identify sustainable value improvement opportunities.

You will partner with Design Engineering, Procurement, Category Management, Manufacturing, and suppliers to understand product cost drivers and evaluate alternative materials, manufacturing processes, and design concepts. The role requires strong manufacturing process knowledge, commercial awareness, and the ability to translate engineering data into actionable cost insights.

Key Responsibilities

Develop detailed should-cost and clean-sheet cost models for mechanical components, subassemblies, and complete products

Analyze cost drivers including raw materials, manufacturing processes, cycle time, tooling, labor, machine rates, overhead, yield, and logistics

Partner with Design Engineering to embed design-to-cost and value engineering principles throughout the product development lifecycle

Perform supplier quote analysis and cost breakdown assessments , identifying gaps between supplier quotations and should-cost estimates

Collaborate with Procurement and Category Management to provide fact-based cost insights that support supplier negotiations and sourcing decisions

Evaluate alternative materials, manufacturing processes, design concepts, and sourcing scenarios to improve cost competitiveness without compromising quality or performance

Assess supplier manufacturing processes and recommend opportunities to improve productivity, manufacturability, and cost efficiency

Build product-level cost models by consolidating component, assembly, tooling, processing, and supply chain costs

Perform cost-benefit, total cost of ownership (TCO), make-versus-buy, and manufacturing footprint analyses where applicable

Establish standard work, methodologies, assumptions, and validation practices for should costing

Improve cost-model accuracy by benchmarking estimates against supplier quotations, actual costs, and manufacturing data

Lead continuous improvement of costing methodologies, databases, tools, and analytical processes

Provide technical guidance and mentoring to engineers and cross-functional teams on cost engineering and design-to-cost practices

Communicate cost insights, opportunities, risks, and recommendations clearly to technical and business stakeholders

Minimum Qualifications

Bachelor’s degree in Mechanical Engineering, Automobile Engineering, Mechatronics Engineering , or a related engineering discipline

10+ years of experience in should costing, cost engineering, manufacturing cost analysis, or value engineering

Demonstrated experience developing detailed cost models for mechanical components and manufacturing processes

Preferred Qualifications

Deep manufacturing knowledge across CNC machining, sheet metal fabrication, casting, forging, plastics/injection molding, composites, rubber, metal injection molding (MIM), and related processes

Strong understanding of secondary operations, heat treatment, surface treatments, coatings, finishing, and assembly processes

Ability to interpret complex engineering drawings, GD&T, tolerances, material specifications, and BOM structures

Working knowledge of engineering and drawing standards such as ASME, ANSI, ISO, DIN, JIS, and BS

Hands-on experience with should-cost and manufacturing cost tools such as aPriori, DFMA, Costimator, or equivalent platforms

Experience with TCO, NPV, make-versus-buy, supplier cost breakdown, and cost-driver analysis

Proficiency in interpreting 2D/3D engineering data using tools such as Creo, SolidWorks, AutoCAD, or equivalent CAD platforms

Experience supporting VAVE, design-to-cost, teardown, benchmarking, and cost reduction initiatives

Strong understanding of global manufacturing economics, supplier capabilities, and regional cost drivers

Strong analytical skills with the ability to convert complex technical and commercial data into actionable recommendations

Demonstrated ability to influence Engineering, Procurement, Manufacturing, Quality, and Supplier teams in a global, matrixed environment

Strong communication, presentation, negotiation-support, and stakeholder management skills
