- Serve as the on-shift operational decision authority within established procedures and delegated authorities, managing routine operations, execution risks, and initial anomaly response.
- Maintain situational awareness of spacecraft health, mission timelines, ground network availability, communication windows, and operational constraints across a 16-vehicle constellation.
- Identify and resolve mission scheduling conflicts, competing priorities, and operational constraints to maintain mission continuity.
- Coordinate shift turnovers, ensuring accurate transfer of spacecraft status, mission priorities, unresolved issues, and time-critical activities.
- Collaborate with engineering, flight dynamics, payload operations, ground systems, and program leadership to translate mission requirements into executable operational plans.
- Review and approve command products, operational procedures, and mission schedule changes within established authorization limits.
- Lead initial anomaly assessment and operational response activities, coordinating troubleshooting and escalation through established mission processes.
- Ensure compliance with operational procedures, configuration management, mission assurance requirements, and applicable safety standards.
- Maintain accurate operational logs, mission execution records, anomaly documentation, and shift activity reports.
- Participate in operational readiness reviews, mission rehearsals, simulations, and post-event assessments to improve mission performance and crew proficiency.
- Support continuous improvement initiatives focused on operational efficiency, mission planning processes, and crew readiness.
- Support rotating shifts, weekends, holidays, and surge operations as mission requirements dictate.
- Occasional travel to Huntsville, Alabama, or Grand Forks, North Dakota, may be required.

### Qualifications
- Bachelor’s Degree and minimum 4 years of prior relevant experience. Graduate Degree and a minimum of 2 years of prior related experience. In lieu of a degree, minimum of 8 years of prior related experience.
- Active Secret security clearance
- 3+ years’ experience working with spacecraft operations, telemetry monitoring, ground station scheduling, communication windows, and command execution processes.
- 3+ years’ experience supporting anomaly response, operational troubleshooting, incident documentation, and established escalation procedures.

### Preferred Additional Skills
- Experience with Neptune Telemetry, Tracking, and Command (TT&C), Virtual Mission Operations Center (VMOC), or OCEAN software applications.
- Previous experience as a Mission Planner, Shift Lead, Crew Lead, Flight Controller, or Spacecraft Operator with operational leadership responsibilities.
- Experience supporting Low Earth Orbit (LEO) spacecraft, multi-satellite operations, or proliferated satellite constellations.
- Familiarity with flight dynamics products, orbital maneuver planning, conjunction screening, and mission timeline integration.
- Experience coordinating spacecraft activities across engineering, payload operations, ground systems, flight dynamics, and external mission partners.
- Knowledge of operational readiness testing, mission simulations, rehearsals, and on-console qualification or certification processes.
