Lead Propulsion Engineer

Overview

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.

EOI Space is looking for a Propulsion Lead with a strong background in spacecraft propulsion and prior experience on flight programs to lead the development of the spacecraft electric propulsion system, including detailed design of the propulsion subsystem, component and system-level development testing, and subsystem assembly, integration, and test.

This role involves taking ownership across the propulsion development lifecycle, from early prototype testing through design, build, qualification, and production test. It requires hands-on work, collaboration across multidisciplinary teams, and leadership of propulsion-level ConOps and related simulation / toolset evolution.

Responsibilities

• Lead the design, development, verification and validation of the electric propulsion subsystem for an Earth-observing satellite in VLEO.
• Detail-design the propulsion subsystem within the spacecraft architecture, including release manufacturing, assembly and integration drawings, and procurement of propulsion components.
• Define hardware architecture and lead trade studies for propulsion components.
• Collaborate with structures and mechanisms, thermal, software, AI&T, and mission operations teams to integrate and test propulsion functionality hardware-in-the-loop (HIL) and mission testbeds.
• Define propulsion-level ConOps and own the modeling, simulation, and performance analysis of the propulsion system including thrusters, flow control components, tanks, instrumentation, tubing and fittings.
• Develop and implement control laws for thrusters, flow control devices, tanks; own the overall system sizing and propellant technical budgets.
• Manage a small team of propulsion engineers, guiding technical execution, prioritizing tasks, and providing mentorship.
• Participate in design reviews, flight readiness reviews, and contribute to risk assessment and mitigation plans.
• Support flight operations and anomaly resolution with in-depth analysis and post-launch tuning of thruster operations.
• Contribute to company-wide system architecture discussions and roadmap planning from a propulsion perspective.

Qualifications

Compensation

The salary range for this role is $165,000-$220,000 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 factors such as job-related skills, education and experience, certifications, abilities, and internal equity.

Work Location

This onsite role is located in Louisville, CO with up to 25% travel to other locations. Satellite integration for the initial vehicles is happening in EOI's Colorado facility with propulsion testing being conducted in Seattle, Washington.
