Senior Optical Engineer

EOI Space is developing and deploying a network of satellites in Very Low Earth Orbit (VLEO) to provide ultra-high-resolution Earth imagery. We aim to deliver timely and actionable data for commercial and defense applications.

We are on our way to achieving many industry firsts. This demands an ambitious team that revels in leaning into challenges, getting hands on, and working together. EOI Space is looking for a Senior Optical Engineer to contribute to the development, analysis, testing, calibration, and delivery of our electro-optical payload. This is a high-impact, hands-on role focused on developing and delivering flight hardware — fast, reliably, and cost-effectively.

You will be involved in the full lifecycle of the payload development, from concept through operations on orbit.

• Support the design, development, and calibration of high-performance EO payloads for satellite-based imaging
• Perform optical modeling and analysis (e.g., ray tracing, stray light analysis, MTF, SNR, distortion) using tools like Zemax Optic Studio, Code V, or FRED
• Assist in specifying and evaluating optical elements, including lenses, mirrors, filters, and coatings
• Collaborate with mechanical and thermal engineers to ensure optical alignment stability across launch and on-orbit environments
• Support the integration and alignment of optical components and full payload assemblies
• Contribute to optical test setups, including interferometry, collimation, boresight, and environmental testing
• Collaborate in pre-launch sensor radiometric, spectral, and geometric calibrations; collaborate in on-orbit calibration
• Interface with vendors and manufacturing partners for optical component procurement and verification
• Work with systems and software teams to define imaging performance requirements and calibration strategies
• Contribute to the requirements verification for the overall system

• Bachelor’s or Master’s degree in Optical Engineering, Physics, Aerospace Engineering, or a related field
• 5+ years of experience in optical design and/or analysis; substantial experience with satellite-based electro/optical payloads is required
• Proficiency in optical modeling tools (Zemax Optic Studio, FRED, Code V, or equivalent)
• Experience in satellite electro-optical payload calibration
• Mechanical design and analysis software knowledge, such as Solid Works, Ansys, Sig Fit, including numerical analysis software line Python or MATLAB
• Experience with optical alignment and test techniques in a laboratory environment
• Ability to work collaboratively in a fast-paced, cross-functional team

The salary range for this role is $140,000 - $185,000 per year, depending on previous experience.

This is an onsite role to be located in Louisville, CO.
