Satellite Command & Data-Handling (C&DH) System Engineer for Fastwater Staffing

Job Description

**Role overview:**

Our client is seeking a **Satellite C\&DH System Engineer** to support and/or design, integrate, verify, and support the on-board command, control and data management functions for current and next-generation remote sensing \& communications satellite programs. The role will own the C\&DH functional architecture, drive trade-studies, and may provide technical authority throughout the spacecraft life-cycle.

**Tasks summary:**

Architecture Concept \& Requirements

* Translate mission-level requirements into C\&DH functional and non-functional specifications.
* Produce System Requirements, Interface Control (ICDs), and Description documents.
* Perform requirement management and maintain bidirectional traceability throughout the project lifecycle.
* Collaborate with cyber-security to embed resilience and security by design, ECU.

Design \& Development

* Lead detailed design of on-board processors, data-buses (SpaceWire, MIL-1553, CAN, Ethernet), memory subsystems, and I/O interfaces.
* Support software architecture: command sequencing, telemetry packetization, health-monitoring, services, fault-detection-isolation-recovery (FDIR).
* Support Satellite Reference Database development and validation

Cross-Functional Coordination, Stakeholder \& Program Interaction

* Communicate technical status, risk assessments and trade-study results to senior management and/or customers or partners.
* Work with FSW teams to define RTOS, APIs, task scheduling, real-time operating system configuration, services usage.
* Define uplink command formatting, downlink telemetry packet structures, and ground-segment data-handling interfaces (mission-control servers, data-archiving pipelines).
* Coordinate with the TT\&C/PDT engineering and Ground Segment ICDs to ensure end-to-end data integrity.
* Support B\&P (Phase 0 \& pre-phase A).

Integration \& Verification (IVV)

* • Develop verification plans, test matrices, and validation procedures for unit, subsystem, and spacecraft level C\&DH tests.
* • Execute functional tests, bus-protocol compliance, SIL and HIL campaigns.
* • Manage anomaly investigations, root-cause analysis, and corrective-action implementation.

Technical Leadership \& Mentorship

* Mentor, guide junior engineers and interns.
* Act as technical liaison with customers, partners and external vendors
* Act as Continuous Improvement stakeholder
* Contribute to our client's knowledge-base, process enhancements, and standards.

Configuration, Documentation \& Standards Management

* Author and maintain C\&DH standards (bus protocols, data-format conventions, redundancy policies).
* Ensure all artefacts, analysis and documentations are version controlled in PLM environment.
* Support design reviews (SRR, PDR, CDR, MRR/TRR...etc.).
* Support Technology Road-Mapping \& Innovation

On-Orbit \& Operations Support

* Support launch-pre-launch and early-orbit checkout, validate satellite functions, HK and nominal operation
* Support and analyse on-orbit telemetry, update filter parameters as needed.
* • Support SOOH development and associated operator trainings

**Required Qualifications:**

* B.Sc. in Electrical Engineering, Aerospace or related field with 8 years of C\&DH engineering experience on LEO/MEO/GEO platforms.
* Deep knowledge of spacecraft data-bus standards: SpaceWire, MIL-1553, CAN-A, Ethernet, CCSDS packet telemetry/command and PUS services.
* Knowledge in processor, FPGA, firmware and embedded
* 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.
* • Experience with Confluence and JIRA.
* Demonstrated capability to efficiently work with little supervision.
* Ability to distill complex problems to fundamentals to solve with analysis, similarity, or creativity.
* • Demonstrate excellent written and oral communication skills in English; knowledge of French will be considered an asset (Contact with clients outside Quebec and work on deliverables in English).
