We are seeking a highly capable Senior Mechanical Design Engineer (contract/temporary) to support ongoing product development and improvement efforts. This is a hands-on, execution-focused role centered on improving existing designs, building hardware, and driving real-world performance.

The ideal candidate has 8+ years of experience, strong Onshape proficiency, and thrives in a fast-paced, highly collaborative onsite environment.

ROLES AND RESPONSIBILITIES

  • Design and improve components and systems based on existing products (“like design”)
  • Develop and release mechanical designs using Onshape
  • Drive improvements in performance, manufacturability, and reliability
  • Support testing, root cause analysis, and design iteration
  • Prototype and evaluate alternative design approaches
  • Contribute to system integration (mechanisms, motion systems, assemblies)
  • Develop and refine assembly and test processes
  • Collaborate cross-functionally with engineering, manufacturing, and field teams
  • Build, assemble, and validate prototypes and hardware hands-on


  • 8+ years of mechanical design experience
  • Strong proficiency with Onshape (required)
  • Experience across key domains: machined parts, sheet metal, plastics, mechanisms, power transmission, and thermal systems
  • Experience with testing, debugging, and iterative design
  • Strong understanding of DFM and practical manufacturing considerations
  • Hands-on capability, including building and validating designs independently
  • Experience with electromechanical systems and system integration
  • Ability to adapt and improve existing designs
  • Comfortable working onsite in a collaborative environment

Nice to have:

  • Experience with large weldments and structural design (FEA a plus)
  • Experience working around rotating machinery
  • Background in reliability, failure analysis, or assembly/test process development

 Engagement Details

  • Type: Contract / Temporary
  • Location: Onsite (no remote)
  • Duration: 6 month +
  • Start: Immediate
  • Growth Opportunity: This role has the potential to convert to a full-time position based on performance and business needs

Impact of the Role

This role is critical to driving near-term design execution, product improvements, and reliability gains. You will directly influence the performance and success of systems deployed in real-world environments.
