About The Position

We are seeking a highly motivated Senior Mechanical Engineer to join our RAPID engineering team, supporting the development of next-generation semiconductor capital equipment. This role requires a strong technical foundation combined with an ownership mindset—from concept through manufacturing handoff. The ideal candidate thrives in ambiguous environments, brings clarity to requirements, and leads complex engineering efforts end-to-end. As a Mechanical Design Engineer, you will develop sophisticated precision mechanical and opto-mechanical inspection systems. You will take full ownership of the design process—from requirements definition and feasibility studies through detailed design, prototyping, testing, and manufacturing release.

Requirements

Doctorate degree in Mechanical Engineering (or related field) with 2+ years of experience, OR Master’s degree with 4+ years of experience, OR Bachelor’s degree with 5+ years of experience
Strong technical expertise in at least two of the following areas: Structural/FEA analysis, Modal & vibration analysis, Thermal engineering, Fluid flow / CFD
Experience designing mechanical systems
Extensive experience with CAD assemblies and detailed drawings
Experience creating procedures for manufacturing, field installation, and service
Proven track record of taking ownership of sophisticated engineering problems and delivering solutions
Strong decision-making skills with demonstrated accountability and follow-through
Excellent communication and collaboration skills

Nice To Haves

Experience in semiconductor capital equipment or similar high-complexity hardware systems
Familiarity with: Vibration damping and isolation techniques, GD&T, tolerance stack-up, and precision engineering, Manufacturing processes (machining, sheet metal, welding, etc.)
Experience leading projects from concept through manufacturing release
A self-starter who can bring structure to ambiguity
A systems thinker who understands cross-disciplinary trade-offs
A technical leader who takes pride in ownership and delivery
Someone comfortable operating in a fast-paced, multi-project environment

Responsibilities

Lead end-to-end mechanical design and development, from requirements definition through manufacturing release
