Mission Operations Engineer; Entry Level

Mission Operations Engineer (Entry Level) – Millennium Space Systems

Location:

Colorado Springs, Colorado (100% onsite)

As a Mission Operations Engineer, you will be the lead technical authority for Millennium’s on‑orbit spacecraft, overseeing the entire mission life cycle from proposal and design through launch and operations. Your responsibilities include defining operational concepts, developing on‑orbit procedures, and innovating advanced methods of spacecraft operation unique to each mission. You must remain composed in high‑pressure situations, possess in‑depth knowledge of both space vehicles and ground systems, and respond to anomalous scenarios in real time, directly safeguarding Millennium’s critical on‑orbit assets.

• Support every aspect of the mission lifecycle, from proposal/mission modeling, design, integration and test, space vehicle shipment, launch and on‑orbit operations, to decommissioning
• Define ground and mission operations requirements, and flow mission requirements back to the space vehicle
  • Define mission concept of operation and design reference missions
• Design the ground segment, including command and control, mission planning, mission data processing, and the associated infrastructure to support all activities
• Implement and test space vehicle fault and autonomy, including fault detection and response, autonomous space vehicle behavior, and on‑board command and control
• Develop and implement methods of operational automation, to reduce day‑to‑day operator responsibilities
• Create and execute space vehicle simulator tests to validate mission/fault/autonomy design
• Create and execute in‑factory flight vehicle tests to validate mission design compatibility with flight hardware
• Conduct critical ground segment testing, including radio‑frequency compatibility testing, remote ground facility interface testing, and acceptance testing of critical ground assets/locations
• Design and validate the mission “sequence of events” for bus commissioning, payload checkout/calibration, and mission operations
  • Plan and lead formal Mission Rehearsal events to train the mission team and to validate the mission design
• Lead a team of spacecraft and subsystem engineers during launch and early orbit activities to commission the space vehicle(s) for service
• Perform duties of lead technical authority during mission operations for both the space and ground segments
  • Focal for customer and internal leadership during critical mission activities
• Provide oversight of nominal on‑orbit operations for Millennium’s entire fleet of on‑orbit spacecraft
• Other duties as assigned

• B.S. in Aerospace, Electrical, Software, Computer, Mechanical Engineering, or a related field
• Experience with real‑time satellite command and control
• Working knowledge of satellite subsystems, ground systems, space missions, and OPSCON design
• Experience delivering operational products to customer environments
• Willingness to support occasional off‑nominal working hours during critical 24/7 mission operations activities

• Active TS/SCI Clearance
• M.S. in Aerospace, Electrical, Software, Computer, Mechanical Engineering, or a related field
• Experience in leading multidisciplinary technical teams, especially to resolve anomalous scenarios
• Experience with external customer briefing/interfacing
• Deep knowledge of satellite systems engineering, including all satellite subsystems
  • Guidance, Navigation, and Control;
    Electrical Power;
    Thermal Control;
    Telemetry, Tracking, and Command;
    Propulsion; etc.
• Experience with Spacecraft Command & Control software systems
• Experience with iterative and agile processes
• Knowledge of orbital dynamics, maneuver planning, and orbit determination techniques
• Experience designing fault detection and response, as well as designing space vehicle autonomy
• Familiarity with software and scripting tools such as MATLAB, Python, C/C++, Java, etc.
• High level of organization, self‑motivation, and an ability to manage many projects in parallel

• Export Control compliance: must be a U.S. Person as defined by 22 C.F.R. § 120.62
• Position does not require a Security…
