What You’ll Work On  

This position will work in the environmental research product development group on new sensor design.

The Senior Mechanical Design Engineer is responsible for the mechanical design, analysis, and testing of electronic instrumentation and measurement systems. Design work will likely include 3D machining, sheet metal, plastic molding, optics, fluids, and gas flow. Responsibilities include the selection and definition for materials, processes, mounting, packaging, analysis (thermal, vibration, etc.), and other mechanical issues arising in the design of electronic instrumentation and measurement systems.

The Senior designation for this role indicates an individual with additional expertise and years of experience. A senior engineer applies intensive and diversified knowledge of engineering principles and practices in broad areas of assignments. This requires the use of advanced techniques and the modification and extension of theories, precepts, and practices of mechanical engineering and related sciences or disciplines. In the course of product development, a senior engineer is able to exercise independent judgment and decision-making on common engineering problems and methods and receive consultation on more difficult problems.
