Senior Mechanical Engineer

Senior Mechanical Engineer – Advanced Development

Location: On-site – California, USA

Salary: $125,000 – $155,000

Work Type: Full-time

Clearance: US Citizen required

About the Role

We are hiring a Senior Mechanical Engineer to focus on early-stage product and technology development.

This role sits upstream of traditional product development, working on concept generation, feasibility, and prototyping to enable future product platforms.

You will translate high-level ideas into functional mechanical systems, validate concepts through experimentation, and reduce technical risk before full-scale development.

Key Responsibilities

• Lead design and development of early-stage mechanical concepts and prototypes

• Translate product ideas into mechanical architectures and proof-of-concept systems

• Design, build, and test prototype components and assemblies

• Conduct feasibility studies across:

• Thermal performance
• Structural integrity
• Materials and tolerances
• • Develop and maintain 3D CAD models and documentation
• • Execute rapid prototyping (additive manufacturing, machining, soft tooling)
• • Plan and run engineering experiments to validate assumptions
• • Identify and mitigate technical risks early in development
• • Collaborate with electrical, firmware, product, and industrial design teams
• • Evaluate new materials, mechanisms, and manufacturing methods
• • Document findings to support future product development
• • Support transition of validated concepts into production programs
• 
  

Required Experience

• 6–10 years experience in mechanical engineering (R&D / product development)

• Strong experience designing:

• Injection-moulded components
• Machined parts
• Sheet metal assemblies
• • Proven experience in rapid prototyping and iterative development
• • Strong CAD skills (SolidWorks preferred)
• • Solid understanding of:
• Materials
• Mechanisms
• Thermal management
• Structural design
• • Experience integrating mechanical systems with electronics (preferred)
• • Ability to move quickly from concept to prototype

Tools & Environment

• SolidWorks or equivalent CAD tools

• Standard prototyping tools and fabrication methods

• Microsoft tools (Teams, Excel, Visio, Project, Word)

Additional Information

• On-site role in California

• Highly collaborative, cross-functional engineering environment

• Focus on innovation, experimentation, and next-generation product platforms
