Sr. Mechanical Engineer

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 System Engineer - Optical, you will lead the design, development, integration, and optimization of precision 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 optical and 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.

You will own free-space optical system design, validation. You will set product vision at the system level, lead design of optics, detectors, circuit boards, precision mechanisms, and mechanical enclosures that must meet user requirements, and ensure the product can be manufactured at high rate.
