Executive Summary
A leading innovation team is seeking a Concept Mechanical Design Engineer to join a hands-on, high-impact environment focused on prototyping and validating early-stage mechanical systems for automation technology. The ideal candidate is a creative engineer with deep mechanical expertise, a passion for building and iterating, and comfort working collaboratively across engineering disciplines to develop concepts that inform future large-scale solutions.

Key Responsibilities

Invent, prototype, and test mechanical systems, structures, and mechanisms—using CAD modeling, documentation, and shop-floor builds
Determine technical viability of concepts quickly, staying aligned with business and operational constraints
Collaborate closely with electrical, software, and systems engineers for integration and successful prototyping
Produce detailed prototypes, simulations, proof-of-concept builds, and provide input for major architectural and product decisions
Apply FEA tools to inform and validate mechanical designs
Translate concepts into scalable solutions that demonstrate readiness for downstream production teams

Skills & Qualifications

Bachelor’s or Master’s degree in Mechanical Engineering (or related field)
5+ years of hands-on mechanical engineering experience (robotics, aerospace, automotive, or safety-critical, high-volume manufacturing a strong plus)
Proficiency with CAD (SolidWorks, NX, or equivalent) and drawing standards (including GD&T)
Deep knowledge of materials, fasteners, tolerancing, and fundamental mechanical/thermal considerations
Skilled in the use of FEA tools (ANSYS, Abaqus, SolidWorks Simulation) and applying analysis to real designs
Proven ability to build and work in shop environments
Experience with product development from concept to production in fast-paced, high-ownership settings
Excellent communication, problem-solving, and organizational skills

Preferred Qualifications

Experience shipping hardware at scale in safety-critical applications
Personal portfolio of engineering projects or prototypes
Demonstrated passion for craftsmanship and innovation
Thrives in high-integrity and impact-driven environments
