Welcome to Planet. We believe in using space to help life on Earth.

Planet designs, builds, and operates the largest constellation of imaging satellites in history. This constellation delivers an unprecedented dataset of empirical information via a revolutionary cloud-based platform to authoritative figures in commercial, environmental, and humanitarian sectors. We are both a space company and data company all rolled into one.

Customers and users across the globe use Planet's data to develop new technologies, drive revenue, power research, and solve our world’s toughest obstacles.

As we control every component of hardware design, manufacturing, data processing, and software engineering, our office is a truly inspiring mix of experts from a variety of domains.

We have a people‑centric approach toward culture and community and we strive to iterate in a way that puts our team members first and prepares our company for growth. Join Planet and be a part of our mission to change the way people see the world.

Planet is a global company with employees working remotely world wide and joining us from offices in San Francisco, Washington DC, Germany, Austria, Slovenia, and The Netherlands.

The New Product Introduction (NPI) Team is responsible for developing and scaling the assembly, integration, and test operations for our next generation of satellites. This includes establishing high-precision manufacturing processes for complex optical telescope payloads.

As a critical member of the NPI team, the Senior Optical Manufacturing Engineer will be the technical leader responsible for translating the optical telescope design from the development phase to a sustainable, high‑yield production environment. You will collaborate closely with design engineers, test engineers, and other cross-functional teams to establish the overall optical manufacturing processes and work instructions, from component assembly through final spacecraft integration.

This role is ideal for individuals who enjoy hands‑on work in building and testing complex, high‑precision optical products and take a methodical approach to pioneering and scaling manufacturing operations.

This is a full‑time, in‑office position based in our San Francisco HQ 5 days per week.

• Support the Assembly, Integration, and Test of optical telescope payloads
• Develop/document optical telescope assembly procedures and work instructions including precise metrology, warm and cold alignment, and performance testing of telescopes and imaging systems
• Design, develop, and implement mechanical and electrical tooling, fixtures, and Ground Support Equipment (GSE) for optical telescope assembly and test in a cleanroom
• Perform analysis of measured data for alignment, calibration, and characterization of imaging systems, and monitor production metrics
• Drive timely resolution of non‑conformances (NCRs), identify root causes, and implement corrective actions and continuous improvement processes
• Provide critical Design for Manufacturability (DFM) and Design for Assembly (DFA) feedback to the optical and mechanical design teams
• Provide technical oversight for external vendors and suppliers involved in optical component manufacturing and assembly
• Participate in the training of optical production technicians to transition the manufacturing line from R&D to production
• Recommend facilities and capital equipment improvements to scale manufacturing processes

• Bachelor's degree in Optical Engineering, Manufacturing Engineering, Electrical Engineering, or a related technical field
• 6+ years of total relevant experience, of which 3+ years directly in the assembly, integration, alignment, and test of complex optical instruments, telescopes, or space‑based imaging payloads
• Hands‑on experience with complex optomechanical assembly, alignment, integration, and bonding in a cleanroom environment
• Experience leveraging technical software for design and analysis (e.g., Zemax, MATLAB, Python, and/or C/C++)
• Expertise in reading technical drawings and using Solid Works or equivalent CAD software to develop tooling and fixtures
• Experienc…
