About the role

Overview

 

Join a dynamic and innovative R&D team dedicated to developing the next generation of light scattering, field-flow fractionation (FFF), and chromatography-based analytical instruments. As a Senior Mechanical Engineer, you will lead the design, development, integration, and optimization of precision mechanical and optomechanical systems from concept through production.

Working in a multidisciplinary environment spanning optics, fluidics, electronics, firmware, software, and chemistry, you will be responsible for architecting robust mechanical solutions that enable best-in-class instrument performance, reliability, manufacturability, and serviceability. You will play a key role in advancing new technology platforms while mentoring junior engineers and driving engineering best practices.

 

 

Responsibilities

  • Develop and create detailed design and mechanical layout of components, subassemblies, and top-level instruments from concept through production
  • Develop and review design concepts, drawings, bills of material, and assembly processes
  • Conduct detailed engineering analysis and test of components, subassemblies, and instruments to verify design and specification goals
  • Perform mechanical, fluid, thermal, and systems analyses to support new and existing designs
  • Lead in prototype build and preproduction activities
  • Develop, design and implement equipment, tooling, fixturing, and processes to achieve production requirements for safety, delivery and cost
  • Provide assignments and technical mentoring to junior level Engineers, Designers, and Technicians
  • Broadly utilize DFM (Design For Manufacture) methods and GD&T
  • Prepare, follow through with, and present design and drawing reviews
  • Work closely with NPI (New Product Introduction) to support the smooth transition of design into volume manufacturing

Qualifications

Education:

  • Bachelor’s Degree in Mechanical Engineering
  • Master’s Degree in Mechanical Engineering preferred

Experience:

  • Minimum of 3 years industry experience in design and analysis of precision mechanical/electromechanical components/assemblies for production/

Skills:
