Lead Mechanical Engineer – Help Build the Future of High-Volume Optical Hardware!

Gardena, CA (Onsite)

Opportunity Summary

A well-funded stealth startup is pioneering next-generation optical computing systems that could redefine how information is processed at scale. Backed by experienced founders and investors, the company is vertically integrating manufacturing, photonics, and automation to create a platform capable of operating at unprecedented speeds and reliability. We’re seeking a Lead Mechanical Engineer to design and launch our production infrastructure from the ground up. This is a hands-on role for someone who thrives at the intersection of mechanical design, manufacturing systems, and automation. You’ll own everything from line layout and tooling to equipment selection and throughput optimization.

About Us

We’re a stealth-stage deep tech startup headquartered in Los Angeles, driven by a mission to harness the power of light for computing. Our team brings together leaders from frontier tech ventures with backgrounds in advanced manufacturing, hardware engineering, and photonics. We are designing both the technology and the production ecosystem to support scalable, reliable, and ultra-high-speed optical systems.

Job Duties

• Lead the end-to-end design and implementation of a precision manufacturing line for optical hardware, including takt-time modeling, ergonomic analysis, and facility-level 3D layout
• Define equipment needs across processes such as wafer bonding, flip-chip attach, die bonding, AOI, wire bonding, and thermal/environmental testing
• Manage vendor relationships for tooling procurement and commissioning
• Build digital models of production stations to evaluate throughput and failure modes
• Develop poka-yoke fixtures and automated test setups for final inspection, including bit error rate validation and firmware loading
• Create mechanical design rules that enable speed and repeatability in production
• Conduct root-cause analysis for downtime and lead corrective action implementation
• Oversee key metrics like first pass yield, OEE, and maintenance scheduling
• Interface with software, electrical, and process engineering teams to ensure line integration

Qualifications

• BS or MS in Mechanical Engineering or a closely related field
• 5+ years of experience owning mechanical design or production systems for high-volume electro-mechanical or optoelectronic products
• Strong CAD background; able to independently release full mechanical design packages, including tolerancing and stack-up analysis
• Familiar with PLC-controlled equipment, robotics, automation, and traceability in production environments
• Willing to work flexibly, including occasional extended hours to support build timelines

Preferred Experience

• Hands-on ability to support rapid problem-solving—whether that means machining a quick part, soldering, or writing a script for test automation
• Familiarity with high-reliability production environments (e.g. defense, aerospace, photonics, or semiconductor)

Security Clearance

• Must be able to obtain US Secret clearance.

Why Join Us

• Early-stage equity in a high-growth, frontier tech company
• Opportunity to own core infrastructure in a vertically integrated startup
• Medical, dental, and vision insurance
• Paid parental leave and flexible PTO policy
• Strong ownership culture with opportunities to grow alongside the company
• Relocation assistance available
• Work closely with technical founders on high-impact, deep tech systems

Compensation Details

$130,000 - $200,000 plus equity
