Responsibilities

• Develops and maintain automation scripts and CI/CD pipelines for operational workflows;
• Manages version control, configuration management, and deployment of software changes;
• Troubleshoots, optimizes, and monitors FDS performance and stability;
• Documents all developed systems and workflows in Confluence and technical documentation;
• Collaborates with the SOC Systems team and external vendors to integrate new operational capabilities;
• Provides technical mentorship to the FD team on software development best practices;
• Leads Flight Dynamics System (FDS) development; tailoring processes to manage the Lightspeed constellation;
• Guide development of a Space Situational Awareness System (SSAS) and integration to an external SSA service;
• Lead orbit management CONOPS for all phases of the Lightspeed mission; including Launch and Early Operations (LEOP), Electric Orbit Raising (EOR), nominal on-station operations, SSA strategy and end-of-life deorbit;
• Guides on-station satellite maneuver strategy to meet station-keeping requirements; maintaining LEO orbit planes and individual satellite tracking strategies, while minimizing fuel usage;
• Optimizes FDS system to monitor and maintain orbit determination and maneuver reconstruction processes;
• Manages propellant usage tracking and maneuver performance analysis;
• Leads automation development; including FDS scripts for maneuvers, momentum dumping and propellant guaging;
• Supports LEOP/IOT/EOR campaigns; planning EOR strategies, performing orbit determination and generating tracking predicts for internal and external Lightspeed segments as necessary;
• Manages ongoing development of the Flight Dynamics System maneuver planning software;
• Prepares and presents reports and presentations for Telesat Lightspeed technical management.

Education and Experience

• Masters or Bachelor degree in Applied Mathematics, Physics, Aerospace Engineering or Computer Science or the equivalent;
• A background in statistics, calculus, classical mechanics, celestial mechanics and computer programming is required;
• Minimum 9-14 -years of relevant work experience directly or commensurate to space orbital dynamics;
• Experience in performing satellite station-keeping planning;
• Experience in developing software and with a variety of platforms and programming tools using modern scripting languages, however, operational procedure scripting languages will also be used so the ability to learn new tools is critical;
• Experience with Linux systems administration Python programming and configuration management is an asset;
• Experience with Machine Learning and Data Analytics is a valued asset;
• Strong technical, presentation, interpersonal, written and communication skills;
• Independent and self-motivated, with the ability to work effectively in a team environment;
• Work requires considerable attention to detail;
• Knowledge of containerized software platforms is an asset.

Decision Making and Supervision

• Independent technical decision-making on software architecture, integration, and automation;
• Works under general direction of the Senior FD Specialist, but sets technical priorities for software infrastructure and collaboration with the SOC Systems team;
• Influences operational decisions indirectly through robust and reliable software solutions;
• Leads the development team in the management of Flight Dynamics related activities, including use of the FDS development system for the purpose of testing and rehearsals;
• Manage development projects including collaboration with Satellite Engineers and Space Segment to implement timely and effective systems for new programs or in response to satellite anomalies;
• Provide technical guidance to senior and junior analysts.

• Successful candidate must possess (or be eligible to obtain) a CGP security clearance.
• Working environment is nominally at Telesat headquarters in Ottawa or at the Gatineau office (normal business hours).
• Some off-hours work is for anomaly response and rehearsals/testing.
• The candidate can expect to support on-call as well.
• There will be occasional international travel as required.
