Spacecraft Systems Engineer

Who We Are

EOI Space specializes in 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, and 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.

The Spacecraft Systems Engineer will support the development and verification of the spacecraft system architecture, emphasizing cross‑subsystem integration performance. This role involves technical execution across design, modeling and simulation, integration, and test phases, working closely with subsystem leads, test engineers, and program management to ensure cohesive spacecraft development.

• Support definition and evolution of the spacecraft system architecture, including subsystem interfaces, performance budgets, and trade studies
• Develop and maintain system‑level requirements, allocations, and verification planning across the satellite lifecycle
• Perform and document system‑level analyses (e.g., power, thermal, link, mass, data)
• Support coordination between subsystem leads, program management, and manufacturing teams to ensure technical alignment and system integrity
• Develop and contribute to Interface Control Documents (ICDs), CONOPS, and other system‑level documentation
• Develop and execute mission analysis and simulation tools, such as day‑in‑the‑life simulations
• Assist with system integration and environmental testing activities, including test plan creation, procedure development, and test execution
• Participate in mission assurance and launch integration efforts
• Identify technical risks and contribute to mitigation planning
• Provide hands‑on support during integration and troubleshooting of spacecraft hardware and software

• B.S. or M.S. in Electrical, Aerospace, Mechanical Engineering, or a related field
• 5–10 years of relevant engineering experience, including spacecraft or subsystem development
• Expertise in at least one spacecraft subsystem (e.g., power, ADCS, thermal, propulsion, communications) and familiarity with system‑level integration
• Experience with modeling and analysis tools such as Python, STK, or MATLAB
• Strong analytical and problem‑solving skills, with a collaborative approach to technical challenges
• Experience with spacecraft development, integration, and testing processes
• Ability to communicate complex technical concepts effectively across teams
• Startup or small‑team experience is preferred

The salary range for this role is $120,000 – $180,000 per year, depending on previous experience. Individual pay will be determined on a case‑by‑case basis and may vary based on the candidate’s qualifications and internal equity.
