About The Position

The ECLS (Environmental Control & Life Support) Flight Controller serves as the real-time systems engineer responsible for Dream Chaser spacecraft thermal management and environmental control systems during mission operations. Operating from the Taylor Mission Control Center in Louisville, CO, the ECLS Flight Controller monitors spacecraft telemetry, executes procedures, commands thermal control systems, and provides real-time technical decisions to ensure spacecraft environmental health and mission success. They represent the ECLS subsystem within the integrated Flight Control Team (FCT), working alongside 10 other console positions under the direction of the Flight Director. The ECLS Flight Controller monitors real-time telemetry, analyzes system performance, troubleshoots anomalies, executes nominal and contingency procedures, and coordinates with Engineering Support Room (ESR) personnel to resolve technical issues. During missions, ECLS provides 24/7 coverage through rotating 9-hour shifts, maintaining spacecraft thermal control and environmental systems. This role embodies the seven Foundations of Flight Operations—Discipline, Competence, Confidence, Responsibility, Toughness, Teamwork, and Vigilance—and operates under the principle that "spaceflight will never tolerate carelessness, incapacity, and neglect."

Requirements

Bachelor's degree in Mechanical Engineering, Aerospace Engineering, Thermal Engineering, or related field (or equivalent work experience in lieu of degree or Masters + 3 years experience).
Typically 5+ years of related experience in thermal systems, spacecraft operations, aerospace test operations, or related technical field (or Masters + 3 years of experience).
Strong understanding of thermodynamics, heat transfer, fluid mechanics, and thermal control system principles.
Knowledge of requirements management, system integration, verification/validation principles, and systems development lifecycle.
Ability to analyze complex technical data and make sound decisions under time pressure in dynamic, real-time operations environments.
Clear, concise verbal and written communication skills; ability to articulate technical issues to diverse audiences including Flight Director and Flight Control Team.
Demonstrated ability to work effectively in multi-disciplinary teams with strong interpersonal and collaboration skills.
