Senior Opto-Mechanical Engineer

Job DescriptionJob Description

Who we are: 

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.  Does this sound like you?  EOI Space is looking for a Sr Opto-Mechanical Engineer contribute to the mechanical design and associated analyses 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 development across the lifecycle of payload development through design, assembly, test, and iteration. 

What you will do: 

You will bridge the gap between optical performance requirements and mechanical design, ensuring our imaging systems deliver exceptional results while withstanding the rigors of launch and space operations. You’ll work within a team of optical, mechanical, systems, and AIT engineers to shepherd the optical payload from design through assembly, testing, and spacecraft integration. 

Responsibilities: 

• Collaborate with optical engineers to develop space-based optical payload by reviewing layouts for mechanical feasibility, material CTE constraints, assembly complexity, and suggesting targeted improvements for manufacturability 

• Perform detailed tolerance analysis to ensure optical integrity across operational conditions, launch vibration, thermal cycling, and long-term material stability 

• Implement solutions for maintaining optical alignment during payload assembly, launch vibration, and on-orbit thermal variations using kinematic mounts, flexures, and low-CTE materials 

• Conduct comprehensive structural/thermal/optical analysis using FEA/FEM tools to predict system performance in space environments, including assembly, launch loads, zero-G, and extreme temperature cycles 

• Identify components sensitive to temperature gradients and heat loads using thermal modeling, empirical data, and heritage knowledge from prior missions 

• Create detailed CAD models and engineering drawings for structural and optical components 

• Rapidly progress and ensure they comply with spacecraft integration requirements, industry standards, and materials outgassing criteria 

• Design reliable mechanical systems for operational adjustments, including focus mechanisms, alignment stages, and one-time deployment mechanisms with redundant features 

• Coordinate with suppliers on component specifications, manufacturing capabilities, specialized material requirements, and delivery timelines for long-lead items 

• Conduct design reviews with vendors and implement quality assurance processes for critical optical components 

• Support integration and testing activities for payload systems, including vibration testing, thermal vacuum cycling, and optical performance verification 

Required Qualifications: 

• Bachelor’s or Master's degree in Aerospace, Mechanical, Optomechanical, or similar engineering 

• 8+ years of experience with optomechanical hardware 

• 5+ years of experience with space flight hardware 

• Demonstrated experience in designing, building, and delivering optical systems for space applications 

• Deep understanding of optomechanical design methods and practices 

• Proficiency with 3D CAD modeling (SolidWorks), detailed mechanical drawings. Detailed optical drawings 

• Proficiency with finite element structural, dynamics, and thermal analysis (Ansys, SolidWorks Simulation) 

• Experience with precision mechanical assembly and alignment operations 

• Demonstrated ability to create design from conceptualization through production 

• Excellent problem-solving, communication, and cross-functional collaboration skills. 

Compensation: 

The salary range for this role is $140,000-$190,000 per year, depending on previous experience. Pay ranges are determined by role, level, location, and alignment with market data. Individual pay will be determined on a case-by-case basis and may vary based on the following considerations: interviews and an assessment of several factors that are unique to each candidate, job-related skills, relevant education and experience, certifications, abilities of the candidate and internal equity. 

Work Location: 

This role can be in either Louisville, CO or in Seattle, WA. Satellite integration for the initial vehicles is happening in EOI’s Colorado facility with a planned transition to Seattle. For candidates that are in Seattle, extensive travel is required to be on-site at the Louisville, CO facility.
