What is the difference between Freelance Prototype Build Engineer vs Mechanical Design Engineer?

AspectFreelance Prototype Build EngineerMechanical Design Engineer
CredentialsRelevant technical skills, certifications in prototyping or manufacturingDegree in Mechanical Engineering, CAD certifications
Work EnvironmentFreelance, project-based, often on-site or remoteFull-time, in-house or design firm offices
Industry UsageProduct startups, hardware companies, prototyping firmsManufacturing, product design, engineering firms

The Freelance Prototype Build Engineer focuses on creating physical prototypes for various projects, often working independently on short-term contracts. In contrast, Mechanical Design Engineers primarily develop detailed mechanical designs and specifications for products within a company or design team. While both roles require technical skills and engineering knowledge, the freelance prototype builder emphasizes hands-on prototyping, whereas the mechanical designer emphasizes design development and CAD work.

Provo, UT • On-site

$80K - $120K/yr

Full-time

Re-posted 25 days ago

Job description

Compensation: $80,000 to 120,000 salary • Full-time • On-site
Location: Provo, UT
About Elkington Motors
We build high-performance electric vehicles that are affordable, personalized, and built to last. Our team is small, fast, and obsessively hands-on, designing, testing, and iterating to ship real product, not slide decks.
The Role
You'll be the mechanical owner who shapes the physical DNA of our EVs. From motor mounts and battery enclosures to thermal management and chassis integration, you will take parts from a blank CAD screen to a physical, bolted-on reality. Expect to wrench, prototype, weld, and iterate until every component survives the rigors of the road and meets our performance targets.
What You'll Do
  • Design and integrate power electronics, wiring harnesses, and control systems for motors, inverters, and battery packs.
  • Prototype and build: use bench and shop tools (scopes, soldering stations, 3D printers, test rigs) to create test fixtures and "Rev A" boards for immediate vehicle testing.
  • Validate and troubleshoot: perform electrical testing (power delivery, thermal cycling, EMI) and diagnose electrical or wiring failures.

Must-Haves
  • B.S. in Electrical Engineering (required).
  • 3+ years of full-time, professional experience in electrical design (automotive, aerospace, robotics, power electronics or other equivalents).
  • Advanced EV related product design proficiency.
  • Hands-on Bench Skills: Comfortable in a lab/shop environment with a deep understanding of schematic capture, battery, VCU, and other EV related components.
  • Strong troubleshooting mindset: You can methodically isolate shorts, noise, or electrical faults and fix them.
  • Startup attitude: Ownership, urgency, and "whatever-it-takes" follow-through.

Why Elkington Motors
  • Direct impact: Your work lands in vehicles - fast.
  • Modern tech stack: Latest materials, rapid prototyping tools, and iterative design.
  • Low red tape: Clear goals, quick decisions, high accountability.

Details
  • Start date: Immediate
  • Work setting: On-site, shop/test environment; significant lifting, bending, and vehicle assembly work required.
  • Work authorization: Must be authorized to work in the U.S.
