Job description

Junior Optical Technician
Location: Los Angeles, CA
About Observable Space
At Observable Space, we're redefining how humanity observes and connects with the universe. We're a vertically integrated, high-growth, space technology company building industry-leading precision optics platforms for Earth and in space. Our systems are trusted by NASA, JPL, SpaceX, Boeing, Raytheon, and the US DoD, among others, and power the work of leading research institutions.
We combine precision opto-mechanical hardware, embedded computing, cloud orchestration, and developer-friendly APIs into world class products. From advanced ground stations, on orbit sensor suites, free space optical lasercom, to distributed compute platforms, we deliver the foundational systems enabling continuous, real-time navigation, observation, and communication in space.
Observable Space is backed by top-tier institutional investors including Lux, Upfront Ventures, RTX Ventures, Detroit Venture Partners and Embedded Ventures.
About the Role
We are seeking a highly motivated and detail-oriented Junior Optical Technician to join our growing team. In this role, you will support the assembly, alignment, testing, and maintenance of optical and optomechanical systems used in telescope platforms. You will work closely with optical, mechanical, and electrical engineers to ensure high-performance imaging systems are built and validated to exacting standards.
What You'll Do
  • Assemble, align, and integrate optical and optomechanical components, including lenses, mirrors, sensors, and fiber-optic systems.
  • Support the setup and execution of optical tests, calibrations, and performance verification procedures.
  • Assist in troubleshooting optical systems and identifying root causes of performance issues.
  • Follow detailed work instructions, assembly drawings, and engineering documentation to build precision systems.
  • Maintain accurate documentation of builds, test results, and system configurations.
  • Support prototype builds and iterative development cycles in a fast-paced environment.
  • Collaborate with engineering teams to provide feedback on assembly processes, tolerances, and design improvements.
  • Assist with inventory management of optical components, tools, and lab equipment.
  • Support manufacturing and integration teams with assembly, testing, and quality control activities.
  • Communicate effectively with team members to ensure alignment on project requirements and timelines.

What You'll Bring
  • Associate's degree, technical certification, or relevant hands-on experience in optics, engineering technology, physics, or a related field (Bachelor's degree is a plus but not required).
  • 0-3 years of experience in optical assembly, lab work, or precision mechanical/technical environments.
  • Basic understanding of optical components and systems (lenses, mirrors, alignment concepts).
  • Experience working with hand tools, microscopes, alignment equipment, or lab instrumentation.
  • Strong attention to detail and ability to work with precision components.
  • Ability to read and interpret technical drawings, procedures, and documentation.
  • Strong communication and teamwork skills.
  • Comfortable working in a hands-on, fast-paced environment.

Preferred Qualifications
  • Experience with optical alignment techniques and test equipment (e.g., interferometers, collimators, alignment lasers).
  • Familiarity with optomechanical assemblies or telescope systems.
  • Experience working in cleanroom or controlled lab environments.
  • Basic knowledge of electronics or embedded systems is a plus.
  • Exposure to CAD tools (SolidWorks or similar) for interpreting designs.
  • Experience supporting prototype builds or R&D environments.
  • Passion for astronomy, optics, or scientific instrumentation.

Why You'll Love It Here
  • Competitive Compensation - A salary package aligned with industry standards and your experience.
  • Equity Opportunities - Take part in our success with stock options.
  • Flexible Work Environment - Enjoy working from our office or in a hybrid work setup with the flexibility to work remotely part of the week. We require a minimum of 3 days per week in our office to support collaboration and team culture. (LA Office only)
  • Unlimited PTO - Take the time you need with our flexible, trust-based vacation policy, including paid holidays. We encourage everyone to rest, recharge, and take care of themselves.
  • Health & Wellness - Comprehensive medical, dental, and vision coverage with 100% of the premium paid by the employer for employees.
  • Cutting-Edge Tools - Get access to the latest hardware and software you need to do your best work.
