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.

Additional Information
