Field Optical Engineer

Technical Sales Associate at Optofidelity Job Overview

Opto Fidelity is seeking a motivated, hands-on Field Optical Engineer to join our internal team in Cupertino, CA, supporting AR/VR/MR component- and system-level testers. This role is ideal for early-career professionals—recent Master’s or Ph.D. graduates—or candidates with 2–4 years of relevant experience. You’ll gain broad exposure to cutting-edge optical systems, work in a start-up environment with autonomy, and have significant room to grow.

You will travel to client sites to maintain, optimize, and provide feedback on our AR/VR/MR test systems. This role offers a unique opportunity to directly influence Opto Fidelity's next-generation AR/VR/MR testing solutions while advancing your career in optical engineering. As the team grows, this position is expected to evolve into an Optical Design Engineer role or Sales Engineer role.

• Perform installation, maintenance, and troubleshooting of AR/VR/MR optical testers at client locations
• Provide guidance to clients on best practices and usage of Opto Fidelity test systems
• Collect, analyze, and document test data; communicate findings to internal and client teams
• Collaborate with internal design and engineering teams in Finland to improve systems based on field insights
• Support development of automated optical measurement systems and component-level testers
• Participate in an initial training program in Finland with senior optical engineers
• Engage in hands‑on optical alignment and lab work, contributing to prototype‑to‑production testing and system validation
• Design optical lenses and components using tools such as Zemax, Code V, or Light Tools

• BS, MS, or Ph.D. in Optical Engineering, Optics, Materials Science, or a closely related field
• Hands‑on experience in optics or optical characterization through internships, personal projects, or professional experience
• Comfortable aligning optics in the lab and working with complex optical hardware — not just simulations
• Excellent documentation and communication skills
• Willingness to travel 25–50% of the time to US client locations
• Experience with optical lens design using Zemax, Code V, or Light Tools

• Experience with Solid Works or other mechanical design tools.
• Familiarity with Linux
• Knowledge of AR/VR industry, wave guides, or color science
• Background in image quality evaluation or metrology instruments
• Exposure to prototype‑to‑production transitions, system bring‑up, or hardware validation
• 401(k) with company match or Roth options
• Medical, dental, vision, and optional life coverage
• Team events and professional development opportunities
