A robotics, satellite systems and geointelligence pioneer with a 55-year+ story of world firsts and more than 450 missions, MDA Space is a global leader in communications satellites, Earth and space observation, and space exploration and infrastructure. The global MDA Space team of more than 3,800 space experts has the knowledge and know-how to turn an audacious customer vision into an achievable mission – bringing to bear a one‑of‑a‑kind mix of experience, engineering excellence and wide‑eyed wonder that’s been in our DNA since day one. MDA is seeking a System Engineer to perform design, integration, verification, and operational support of TT&C;/PDT subsystems for current and next‑generation remote sensing and communications satellites. The role will interface with spacecraft payload teams, ground‑segment developers, and mission‑operations teams to ensure reliable command delivery, high‑fidelity telemetry acquisition, and robust data handling throughout the satellite life‑cycle.
Define TT&C;/PDT functional architecture (command generation, uplink, telemetry downlink, on‑board data handling, RF front‑end).
Conduct trade‑studies for modulation schemes, coding, frequency plans, ranging and link budgets.
Produce System Requirements, Interface Control (ICDs), and Description documents.
Perform requirement management and maintain bidirectional traceability throughout the project lifecycle.
Lead detailed design of hardware (TT&C; transceiver, RF front‑ends,



antenna‑pointing) and software (command sequencer, telemetry parser, health‑monitoring).
Perform link‑budget analysis, RF simulation (e.g., Verify compliance with CCSDS, ECSS, ITU, and regulatory standards.
Support Satellite Reference Database development and validation.
Present technical status, risk analyses, and trade‑study results to senior management.
Develop test plans, procedures, and verification matrices for unit, subsystem, and spacecraft‑level TT&C; tests.
Execute RF link testing, BER, command latency, and telemetry integrity verification.
Manage anomaly investigation, root‑cause analysis, and corrective actions.
Technical Leadership & Mentorship
Act as technical liaison with customers, partners and external vendors.
Act as Continuous Improvement stakeholder.
Configuration, Documentation & Standards Management
Ensure all artefacts, analysis, software, deliverables and documentations are version controlled in PLM environment.
Support launch‑pre‑launch and early‑orbit checkout – validate command uplink, telemetry acquisition, and on‑board software hand‑over.
Maintain ground‑segment configuration (gateways, mission control servers,



monitoring dashboards).
Sc. in Electrical Engineering, Aerospace or related field with 15+years of TT&C;/PDT System design experience on LEO/MEO/GEO platforms.
Proficiency in RF link‑budget analysis, S‑band/X‑band/Ka‑band modem architecture.
Strong understanding of aerospace system engineering fundamentals, space environment and orbit mechanics.
Hands‑on individual who can support systems integration processes and capability to test systems and resolve problems.
Demonstrated capability to efficiently work with little supervision.
Ability to distill complex problems to fundamentals to solve with analysis, similarity, or creativity.
