The Sr. Mechanical Engineer researches, plans, designs, and develops torque and aviation tools.  The successful candidate will coordinate projects from start to finish, lead prototype and pilot builds, plan and perform relevant testing, conduct statistical analyses of systems, and generate 3D CAD models and production drawings.   Responsibilities also include creating and reviewing detailed drawings, product BOMs, and related materials in the support of release of new product development and sustaining engineering.


While the main elements of the job center on new product development, there will be significant time spent on sustaining engineering of existing products, problem solving, and quality support.  These projects will center on the Snap-on torque and aviation tool businesses.


The Sr. Mechanical Engineer will have good communication skills, superior technical capabilities, be self-motivated, and demonstrate he/she can work under general supervision. Under the direction of engineering management, the Sr. Mechanical Engineer will design new products from prototypes to production-ready documentation and manage product development projects and subtasks.


The Sr. Mechanical Engineer will also support production and QA with dimensional analysis, drawing maintenance and support, and creating and managing ECNs.
