Mechanical Engineer

$85k - $125k

Approach Venture

Mechanical Engineer – Build Next-Generation Hardware at an Advanced Manufacturing Startup!

Los Angeles, CA | On-Site

Opportunity Summary

A rapidly growing deep-tech startup is redefining how advanced computing hardware is designed, manufactured, and scaled. Operating at the intersection of precision engineering, physics, and high-volume production, this team is building complex electro-mechanical systems that push performance limits while remaining manufacturable at scale. As a Mechanical Engineer, you will play a hands-on role in developing highly integrated hardware products from early concepts through production ramp. You'll design everything from micro-scale features to large tooling systems, collaborate closely with electrical, optical, firmware, and process engineers, and directly influence how next-generation hardware moves from prototype to factory floor. If you enjoy solving complex physical problems and seeing your designs manufactured in real time, this is an opportunity to make a tangible impact in a fast-moving startup environment.

About Us

We are a venture-backed technology company building advanced hardware platforms that combine precision mechanics, high-speed electronics, and cutting-edge manufacturing processes. Our team is focused on scaling breakthrough hardware systems that will power the next wave of computing and data infrastructure. By owning both product design and in-house manufacturing, we move quickly, iterate aggressively, and bring complex technology to market faster than traditional hardware companies.

Job Duties
  • Design mechanical components and assemblies from initial requirements through supplier production and manufacturing ramp
  • Develop parts across a wide range of scales, from micro-feature components to large structural hardware and tooling
  • Perform structural and thermal analysis to validate performance and reliability
  • Partner closely with electrical, firmware, optical, and process engineering teams to deliver tightly integrated systems
  • Create fixtures, interfaces, and tooling to support high-throughput manufacturing operations
  • Support design for manufacturability, assembly optimization, and continuous production improvements
  • Translate first-principles engineering concepts into practical, scalable hardware solutions
Qualifications
  • BS or MS in Mechanical Engineering or a related technical discipline
  • CAD proficiency with hands-on project experience
  • Strong foundation in mechanical fundamentals and first-principles problem solving
  • Ability to work in a fast-paced, collaborative engineering environment
Preferred Experience
  • Experience with structural, thermal, or multiphysics analysis tools (ANSYS Mechanical, Icepak, Fluent, or similar)
  • 3+ years of direct experience in a mechanical engineering role supporting product development or manufacturing
  • Exposure to electro-mechanical systems, precision hardware, or advanced manufacturing environments
  • Experience designing for production, tooling, or high-rate assembly lines
Why Join Us
  • Work directly on breakthrough hardware products from concept through production
  • Hands-on ownership in a fast-moving startup environment
  • Opportunity to influence both product design and manufacturing strategy
  • Collaborate with a highly technical, multidisciplinary engineering team
  • Real impact on next-generation computing and hardware infrastructure
