About the Role
We are seeking an experienced Satellite TT&C/PDT Systems Engineer to support the design, integration, verification, and operational support of TT&C/PDT subsystems for current and next-generation remote sensing and communications satellites.
In this role, you will work across spacecraft payload, ground-segment, and mission-operations teams to ensure reliable command delivery, high-fidelity telemetry acquisition, and robust data handling throughout the satellite lifecycle.
Key Responsibilities
- Define TT&C/PDT functional architecture, including command generation, uplink, telemetry downlink, onboard data handling, and RF front-end systems. - Conduct trade studies involving modulation schemes, coding, frequency plans, ranging, and link budgets. - Develop system requirements, Interface Control Documents (ICDs), and system description documents. - Manage requirements and maintain bidirectional traceability throughout the project lifecycle. - Support cybersecurity and resilience considerations within TT&C/PDT system design. - Lead detailed design of TT&C hardware and software, including transceivers, RF front-ends, antenna pointing, command sequencing, telemetry parsing, and health monitoring. - Perform RF link-budget analysis, RF simulation, and error-budget analysis using tools such as STK and MATLAB. - Verify compliance with CCSDS, ECSS, ITU, and applicable regulatory standards. - Support Satellite Reference Database development and validation. - Develop test plans, procedures, and verification matrices for unit, subsystem, and spacecraft-level TT&C testing. - Execute RF link testing, BER testing, command latency verification, and telemetry integrity testing. - Lead anomaly investigations, root-cause analysis, and corrective actions. - Support spacecraft launch preparation and early-orbit checkout, including command uplink and telemetry acquisition. - Provide real-time command and telemetry support during nominal and contingency operations. - Support ground-segment configuration, including gateways, mission-control servers, and monitoring dashboards. - Support SOOH development and operator training. - Support major design reviews, including SRR, PDR, CDR, MRR, and TRR. - Mentor junior engineers and serve as a technical liaison with customers, partners, and external vendors.
Required Qualifications
- Bachelor's degree in Electrical Engineering, Aerospace Engineering, or a related field. - 8+ years of TT&C/PDT systems design experience on LEO, MEO, and/or GEO satellite platforms. - Strong knowledge of: - CCSDS Telemetry/Telecommand packet standards - ECSS telemetry and command protocols - PUS services - ITU frequency regulations
- Proficiency in RF link-budget analysis. - Strong understanding of S-band, X-band, and Ka-band modem architectures. - Strong understanding of aerospace systems engineering fundamentals, space environment, and orbit mechanics. - Hands-on experience supporting systems integration, testing, troubleshooting, and problem resolution. - Experience with Confluence and JIRA. - Ability to work independently with minimal supervision. - Strong analytical and problem-solving skills with the ability to break down complex technical challenges into fundamental components. - Excellent written and verbal communication skills in English.
Preferred Qualifications
- French language proficiency. - Experience supporting end-to-end TT&C/PDT development, integration, verification, and on-orbit operations. - Experience with spacecraft commissioning and early-orbit operations. - Experience with RF link testing, BER testing, and telemetry/command integrity verification. - Experience supporting satellite ground-segment interfaces and mission-control systems. - Experience contributing to satellite technology roadmaps and early-phase program activities.
