This role offers excellent opportunities for professional growth while contributing to meaningful technological advances in fields like healthcare environmental protection and scientific research.

POSITION SUMMARY:

Mechanical Engineer III is a key technical leader supporting New Product Introduction (NPI) through strong Design for Excellence (DFX) execution and technical sourcing partnership. This role ensures mechanical designs are manufacturable scalable cost-effective and aligned with Thermo Fishers business commitments quality standards and PPI culture.

This position operates at the intersection of R&D Procurement Operations Quality and external suppliers providing technical depth structured problem solving and disciplined execution across the product lifecycle.

KEY RESPONSIBILITIES:

Technical Sourcing & Supplier Partnership

• Act as the technical interface between R&D and Procurement for mechanical components and assemblies on assigned mission critical programs.

• Support supplier selection qualification and onboarding by assessing manufacturing capability scalability and risk.

• Conduct technical supplier reviews including DFM/DFA process capability yield and cost drivers.

• Enable early supplier involvement (ESI) to influence design manufacturing strategy and cost outcomes.

• Support Operations and Procurement on make vs. buy decisions using technical cost and operational criteria.

Design for Excellence (DFX) Leadership

• Lead and apply DFX principles across mechanical designs including:

  • Design for Manufacturability (DFM)

  • Design for Assembly (DFA)

  • Design for Cost (DFC)

  • Design for Quality Reliability and Serviceability

• Facilitate structured DFX reviews and workshops with internal teams and suppliers.

• Identify and drive value engineering and cost reduction opportunities while protecting performance and quality by way of DFX proposals to meet target costs.

• Ensure design decisions reflect manufacturing realities and supplier process capabilities.

New Product Introduction (NPI) Execution

• Prepare DFX proposals across all NPI phases following the product development process.

• Participate in prototype builds teardowns design verification validation and production ramp to ensure KPIs and objectives met.

• Drive progressive cost maturity from early estimates to production-released BOM and COGS.

• Identify technical manufacturing and supply risks early and lead mitigation actions.

• Support smooth transfer from development to manufacturing including supplier readiness and process validation.

BOM Cost & COGS Management

• Partner with Procurement and Finance to support COGS transparency and margin commitments.

• Support VAVE (Value Analysis / Value Engineering) and continuous improvement initiatives.

• Apply manufacturing process knowledge to challenge supplier quotes and support should-cost discussions.

Cross-Functional Leadership & PPI Execution

• Collaborate closely with R&D Procurement Operations Quality Program Management and Supply Chain.

• Apply PPI tools and structured problem-solving to technical and operational challenges.

• Influence decisions through data technical rigor and cross-functional alignment.

• Mentor junior engineers and contribute to standard work playbooks and best practices.

MINIMUM QUALIFICATIONS:

• 5 years of experience with BS in Mechanical Engineering or 3 years with MS in Mechanical Engineering roles supporting NPI and manufacturing.

• Strong knowledge of mechanical design including materials selection precision mechanisms system integration

• Strong knowledge & demonstrated proficiency of GD&T tolerance analysis and DFX principles in a product development environment.

• Strong knowledge of manufacturing processes including machining injection molding and sheet metal fabrication

• Experience working directly with external suppliers and contract manufacturers.

• Experience supporting BOM cost and COGS development.

• Expertise in 3D CAD software (SolidWorks Pro/e Creo or similar) and PDM/PLM systems

• Experience dealing with mechanical devices that are regulated by third party agencies such as FDA NSF CSA UL ISO 13485 standard and others in the medical products industry

• Understanding of phase gate development processes and methodologies across multiple disciplines and subject matters is preferred
