Mechanical Engineer

fast-scaling photonics startup Hawthorne, CA Direct Hire Engineering $120,000 - $200,000

Job Summary

We are seeking a Mechanical Engineer with 1-4 years of experience to lead the mechanical design and prototyping of compact seeker units for next-generation missile defense systems. This hands-on role focuses on optomechanical packaging, vibration and shock analysis, and rapid iteration of hardware in a fast-moving startup environment. You will work directly with the lead hardware engineer to deliver prototypes on accelerated timelines where mechanical engineering is a critical capability for the team.

Essential Functions

  • Design and prototype compact mechanical assemblies integrating optical, electrical, and structural components while preserving light paths and alignment under stress
  • Perform vibration, shock, and thermal analysis to ensure hardware meets demanding environmental requirements
  • Rapidly iterate on designs with full cycles measured in days, including design, build, and test phases
  • Develop optomechanical mounts and packaging that maintain photonic alignment while minimizing size and weight
  • Transition prototype designs toward fabrication-ready solutions with manufacturability considered from the start
  • Solve cross-functional problems across packaging, analysis, and system integration in an ambiguous, high-speed setting

Required Qualifications

  • 1-4 years of mechanical engineering experience with hands-on hardware prototyping in aerospace, defense, or robotics
  • Experience completing full design-build-test cycles on real hardware
  • Proficiency in SolidWorks for design of compact electro-optical assemblies
  • Background in vibration, shock, and thermal analysis
  • BS in Mechanical Engineering or a closely related field
  • Ability to work on-site full-time in the Los Angeles area

Preferred Qualifications

  • Experience at a fast-paced hardware company such as those in aerospace or defense sectors
  • FSAE, robotics team, or equivalent hands-on project experience
  • Optomechanical design or alignment-sensitive assembly background
  • Demonstrated ability to prioritize speed and ship prototypes quickly rather than seeking perfection

Technical Skills

  • SolidWorks
  • Zemax
  • FEA and structural analysis
  • Rapid prototyping techniques
  • Vibration and shock analysis
  • Thermal analysis
  • Optomechanical packaging
  • MIL-STD-810 testing
  • Design for manufacturability

Education & Certifications

BS in Mechanical Engineering or a closely related field is required.

Compensation & Benefits

Salary range is $120,000 to $200,000 depending on experience and qualifications. This is a full-time, direct hire position.
