## Job description

## MECHANICAL INTEGRATION & TEST ENGINEER

Mesh Optical Technologies was founded on the belief that optical photons will be at the center of advanced technologies in the coming century. Making advanced technology ubiquitous means building at scale, and that’s exactly what we’re doing at Mesh.

We are seeking a Mechanical Integration & Test Engineer to own the mechanical integration of machines, tooling, fixtures, and workstations across our production lines and development labs. Integration & Test Engineers at Mesh must have a working knowledge of design, manufacturing, and test operations across their domain. A successful engineer on this team demonstrates strong engineering intuition, critical thinking, and comfort working under ambiguous requirements with minimal oversight.

## RESPONSIBILITIES

- Own the mechanical integration of production equipment, tooling, fixtures, and workstations into high-volume manufacturing lines
- Lead mechanical bring-up, debug, and ramp of new and modified production cells, resolving integration issues across mechanical, structural, and thermal boundaries
- Define and maintain system-level mechanical interfaces between tools, fixtures, material handling systems, and factory infrastructure
- Design, build, and qualify test fixtures, workholding, and mechanical hardware interfaces used for qualification, validation, and manufacturing
- Evaluate proposed designs for manufacturability and mechanical integration, providing feedback on assembly sequence, access, tolerance stackups, and fixturing requirements
- Develop and refine assembly procedures, integration sequences, and mechanical validation checklists based on build experience and lessons learned
- Enable day-to-day execution of the mechanical integration and test flow on the production floor
- Evaluate nonconformances to determine root cause and drive corrective action and system improvements
- Maintain mechanical configuration of production lines, including tracking fixture revisions, tooling changes, and equipment modifications
- Interface with both engineers and technicians to optimize manufacturing, assembly, and automation workflows

## QUALIFICATIONS

- Bachelor's degree in mechanical engineering or a related engineering discipline
- 1+ years of hands-on mechanical design, assembly, test, or manufacturing experience (internships, co-ops, and substantive project experience qualify)
- Ability to read and interpret engineering drawings, including GD&T
- CAD proficiency (NX, SolidWorks, or equivalent)
- Strong hands-on skills and comfort building, debugging, and modifying hardware in factory or lab environments
- Demonstrated engineering intuition, critical thinking, and comfort with ambiguity
- Willingness to work extended hours and weekends as needed

## PREFERRED EXPERIENCE

- Experience integrating multi-station production lines, factory automation systems, or complex electro-mechanical assemblies
- Experience designing tooling, fixtures, or mechanical test hardware
- Experience with precision mechanical assemblies or optomechanical systems
- Familiarity with material handling systems, robotic pick-and-place, or automated alignment equipment
- Experience writing assembly procedures, test plans, and providing go/no-go judgment and rationale
- Documentation and configuration management experience in a production environment
- Scripting or data analysis experience (e.g., Python, MATLAB)
- Experience in a production environment with high attention to build quality and process discipline

## COMPENSATION AND BENEFITS:

Pay range: Mechanical Integration & Test Engineer: $110,000.00 - $135,000.00/per year

Title and base salary are determined on a case by case basis commensurate with experience and merit.

In addition to base salary, compensation for this role includes:

- Eligibility for long-term incentives including company stock options and discretionary bonuses awarded for exceptional achievements.
- Comprehensive medical, vision, and dental insurance with significant cost covered by the company for yourself and dependents.
- Paid parental leave and flexible PTO (3 weeks accrued vacation and 10 company holidays per year).
- 401(k) retirement plan access.
- Relocation assistance to sunny Los Angeles.

## About Mesh Optical Technologies

## Company Overview
- **One-liner**: Mesh Optical Technologies designs and manufactures advanced optical systems at scale, targeting hyperscale computing and AI infrastructure.
- **Entity Type**: Private (Series A - $50M led by Thrive Capital, as of February 2026)
- **Headquarters**: Los Angeles, California, United States
- **Founded**: Not publicly available
- **Founders**: Travis Brashears (Co-Founder & CEO), Cameron Ramos (Co-Founder & President)

## Core Business
- **Primary industry**: Computer Hardware Manufacturing / Advanced Optics / Photonics
- **Target customers**: B2B – hyperscale data centers, AI compute clusters, and space-based optical communications
- **Mission or purpose**: "Advance the state of the art in optical manufacturing, closing a critical supply chain gap in hyperscale computing, and building the next generation of optical hardware on Earth and in space."

## Products & Services
- **Alpha C1 optical transceiver**: A 1.6 Terabits per second optical transceiver that linearly translates electrical signals to light. Designed for AI workloads and power-constrained data centers, it delivers better power efficiency, lower latency, and higher reliability. Its optical engine is manufactured entirely with flip chip die bonding – the same technology used to package chips in modern processors – enabling high-volume production.

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: Total funding of $50M (Series A, February 2026)
- **Notable Investors/Partners**: Thrive Capital (lead), plus two other major investors (names not specified)
- **Growth Signals**: 11 employees with 29 open job postings; 20% monthly headcount growth; team includes alumni from SpaceX, Intel, Apple, Helion, and other advanced manufacturing environments

## Competitive Advantages
- **Integrated design & manufacturing**: Unlike most photonics companies that treat manufacturing as a downstream exercise, Mesh designs and builds its own factories, closing the feedback loop between device physics, packaging, yield, and automation.
- **Flip chip die bonding**: The Alpha C1 uses a proven, high-volume chip-packaging technique, allowing rapid scaling to millions of units per year – a major departure from the manual, low-volume assembly typical of US optical manufacturing.

## Strategic Focus
- Scale production of the Alpha C1 transceiver to meet demand from AI clusters.
- Develop new high-volume optical manufacturing techniques for terrestrial and in-space infrastructure (laser links, deep space probes).
- Continue to hire across engineering, operations, and manufacturing to expand its Los Angeles-based factory and R&D capabilities.

## Why Work Here
- **Engineering culture**: "Build your own factory" – the team believes in engineering to the limit of physics and writing software that maximizes hardware capability.
- **Impact**: Opportunity to close a critical supply chain gap in US optical manufacturing and shape the next generation of computing infrastructure.
- **Work environment**: On-site in Los Angeles (two offices in the area); highly technical team with deep expertise from SpaceX, Intel, Apple, and other hardware leaders.
- **Growth**: Rapidly scaling startup with 29 open roles across electrical, mechanical, process, and manufacturing engineering, as well as operations and recruiting.
