Role

MDA is recruiting a junior systems engineer to contribute—under the supervision of senior engineers to the definition, design, implementation and validation of the flight‑software (FSW) and FDIR functions for our current and next‑generation remote‑sensing and communications satellites. The engineer will work primarily in a support capacity, assisting the technical lead during design studies, the preparation of interface documents, and the verification campaign, while gaining comprehensive life‑cycle experience on an embedded system.

- Assist senior engineers during requirement‑gathering workshops and record the requirements in the tracking tool.




- Participate in the allocation process under the direction of the software‑project lead.
- Collaborate with the cybersecurity team to incorporate resilience from the conceptual stage.
- Update traceability links in the requirements‑management system and flag any inconsistencies to the configuration manager.

Software Architecture, Design & Development

- Define the flight‑software (FSW) architecture – RTOS, start‑up procedures, PUS services, satellite health‑monitoring, fault management, and payload interfaces.
- Define FDIR algorithms, isolation logic, recovery actions, safe‑mode sequences, and redundancy management.
- Implement or lead the integration of the FDIR logic into the flight software.
- Produce and maintain Interface Control Documents (ICDs) for payload subsystems, platform subsystems, and ground‑segment interfaces.
- Support the development and validation of the Satellite Reference Database (SRDB) and the Decision‑Support System (DSS).

Cross‑Functional Coordination, Stakeholder & Program Interaction

- Communicate technical status, risk assessments and trade‑study results to program management, customers and partners.
- Act as liaison with payload, platform (including GNC),



ground‑segment and mission‑operations teams to ensure early integration of functions and to resolve integration issues.
- Support the deployment of test‑automation tools and frameworks.
- Assist the definition of test cases, analyze test results and certify test reports.

Technical Leadership & Mentorship

- Guide interns on their tasks and development.
- Serve as the technical point of contact for customers, partners and external suppliers.
- Participate in continuous‑improvement activities and apply lessons‑learned to future projects.
- Contribute to MDA’s knowledge base, process improvements and the development of standards.

Configuration, Documentation & Standards Management

- Ensure that all artefacts, analyses, software, deliverables and documents are version‑controlled in the PLM setting.
- Assist the technology‑road‑mapping and innovation effort by providing input on emerging solutions.

On‑Orbit & Operations Support

- Support and analyse on‑orbit telemetry, update filter parameters, and generate SW updates as needed.
- Support SOOH development and associated operator training.

Required Qualifications

- Sc. in Electrical engineering, Aerospace, Embedded Systems with 0-2 years of previous fault-tolerant systems on LEO/MEO/GEO missions.
- Experience working with CCSDS, ECSS, PUS services.
- Experience working with MIL-1553, SpaceWire, RS422/485, CAN, Ethernet.
- Experience in real-time cores and/or embedded Linux, Auto-coding.
- Strong understanding of aerospace system engineering fundamentals.
- Hands‑on individual who can support systems integration processes and capability. to test systems and resolve problems.
- Experience with Confl
