Opto-Mechanical Engineer 2

Monarch Quantum•San Diego, CA

2d•$85,000 - $125,000•Onsite

About The Position

Join our fast-paced and passionate team as a Opto-Mechanical Engineer 2. As we scale, you will be instrumental in building our foundation from the ground up. This is a dynamic, hands-on role for a self-starter who thrives in a fluid startup environment. You'll have the opportunity to work on cutting edge technologies, work closely with leadership, and develop and implement engineering practices that support our mission and growth.

Requirements

A bachelor’s degree in mechanical engineering, Physics, or a related field.
A minimum of 2 years of relevant experience, ideally within a startup or technology company.
Proficient in 3D CAD modeling and drawing generation (SolidWorks preferred) with demonstrated experience using GD&T (ASME Y14.5).
Familiarity with optomechanical mounting techniques (kinematic mounts, flexures, adhesive bonding of optics/crystals, glass-to-metal joints).
Exposure to fiber handling, fiber alignment mechanisms, or micro-electronic/photonic packaging considerations.
Solid understanding of Design for Manufacturability (DFM) and Design for Assembly (DFA) across precision CNC machining, sheet metal, and small-scale assembly.
Comfortable working in an optical cleanroom/lab environment using hand tools, torque drivers, and optical alignment or measurement equipment.
Must be a U.S. person as defined by 8 U.S.C. § 1324b(a)(3) due to access to export-controlled information.

Responsibilities

Design precision mechanical components and sub-assemblies for photonic systems, including optical isolators, fiber optic connectors, and micro-optic/crystal mounting solutions.
Design and build custom assembly tooling, alignment jigs, and fabrication stations to support low-volume prototyping and high-volume production.
Perform basic tolerance stack-up analysis and thermal/stress evaluations (FEA) to ensure optical alignment is maintained across operating temperatures and mechanical strain.
Create, release, and maintain detailed 2D fabrication drawings adhering to GD&T standards (ASME Y14.5) for CNC machining, precision molding, and sheet metal.
Build and maintain Bills of Materials (BOMs), track engineering prototypes through procurement and fabrication, and manage component inventory for build cycles.
Process Engineering Change Orders (ECOs) and update CAD models and documentation based on design reviews, supplier feedback, or assembly findings.
Support cleanroom or lab-level assembly and alignment of delicate optical and mechanical sub-assemblies using adhesive bonding (UV/epoxy), soldering, or precision mechanical fasteners.
Assist senior engineers in investigating design or manufacturing non-conformances, running root cause analysis (RCA), and implementing corrective actions.
