Spacecraft ATLO Vehicle Engineer

As an end-to-end responsive space transportation company, Firefly Aerospace is on a mission to enable our world to launch, land, and operate in space – anywhere, anytime. Our launch vehicles, lunar landers, and orbital vehicles provide government and commercial customers with full mission services from low Earth orbit to the surface of the Moon and beyond. Headquartered in north Austin, Texas, Firefly is looking for passionate, hardworking innovators to join our team and help fuel our successful trajectory into space.

We are seeking a Spacecraft ATLO (Assembly, Test, Launch Operations) Vehicle Engineer to serve as the mission execution lead for spacecraft from integration through launch. This role acts as the primary ATLO liaison between Program Management and the organizations responsible for spacecraft assembly, integration, test, environmental acceptance, and launch operations.

Assigned to specific spacecraft missions, the Vehicle Engineer maintains end-to-end ownership of the spacecraft through the ATLO campaign, ensuring alignment between schedule, technical execution, configuration management, risk management, and mission readiness. This individual serves as the single point of contact for mission status and coordinates activities across engineering, quality, integration, test, flight software, and launch teams.

• Serve as the assigned Vehicle Engineer for one or more spacecraft missions from integration through launch.
• Own and maintain the ATLO schedule from program CDR through launch operations.
• Maintain holistic awareness of spacecraft configuration, build progress, schedule status, risks, and mission readiness.
• Act as the primary interface between Program Management and production, integration, test, environmental test, and launch organizations.
• Track mission-level action items, risks, constraints, readiness criteria, and critical path activities.
• Support planning and execution of spacecraft assembly, integration, functional test, environmental test, and launch campaigns.
• Develop a detailed understanding of spacecraft architecture, mission objectives, operational concepts, and mission success criteria.
• Understand interactions between spacecraft hardware, avionics, flight software, ground systems, and mission operations.
• Perform or support spacecraft functional testing, commanding, telemetry monitoring, and mission verification activities during integration, environmental testing, and launch preparation.
• Evaluate test plans and verification strategies to ensure mission-critical functionality is adequately tested while maintaining spacecraft safety.
• Support anomaly investigations, risk reviews, readiness reviews, and configuration control activities.
• Assess operational and schedule impacts of engineering changes, software updates, nonconformances, and program decisions.
• Ensure spacecraft configuration integrity and mission readiness throughout the spacecraft lifecycle.
• Drive continuous improvement in mission execution processes, integration flow, and cross-functional coordination.

• Bachelor’s degree in Aerospace Engineering, Mechanical Engineering, Electrical Engineering, Systems Engineering, Computer Engineering, or a related technical discipline.
• 5+ years of experience supporting spacecraft, launch vehicle, aviation, or other complex aerospace systems.
• Experience supporting spacecraft integration, functional testing, environmental testing, launch campaigns, mission operations, and systems engineering activities.
• Working knowledge of spacecraft avionics, command and telemetry systems, and flight software concepts.
• Experience supporting spacecraft functional testing, mission simulations, or end-to-end vehicle verification activities.
• Strong understanding of spacecraft systems, integration, test, and launch operations.
• Experience working across engineering, manufacturing, and program organizations.
• Excellent organizational, communication, and technical leadership skills.

• Experience with spacecraft configuration management, risk management, and change control processes.
• Experience as an ATLO lead on a spacecraft mission
