Role overview:MDA is seeking a
Satellite Bus System Engineer to design structural, thermal, power distribution, attitude control, propulsion, CD&H, TT&C/PDT, FSW and interface architecture that supports payloads and mission-operations for current and next-generation remote sensing and communications satellites. The role leads the definition, design, integration, verification and on-orbit support of the platform subsystems, ensuring compliance to mission requirements and MDA best-practice processes.
Tasks summary:Architecture Concept & Requirements
- Translate mission-level requirements (CONOPs, mass, volume, power, envelope, pointing, lifetime, redundancy, reliability...etc.) into system requirements and allocate them to platform subsystems (structures, TCS, EPS, GNC, PROP, C&DH, TT&C/PDT, FSW).
- Develop the Platform Architecture Description Document, Interface Control Documents (ICD) and Design Description.
- Perform requirement management and maintain bidirectional traceability throughout the program life cycle.
Concept Trade & Feasibility
- Lead trade studies for structural approach, thermal control concepts (MLI, heat pipes, radiators...etc.), power generation options (e.g. solar array & battery technologies).
Detailed Design
- Oversee detailed design of all major subsystems (structures, TCS, EPS, PROP, C&DH, C&T, GNC, payload interfaces).
- Conduct failure-mode-effects-analysis (FMEA) in support to FDIR, fault-tree analysis and reliability & availability predictions.
- Ensure compliance with mission requirement and payload specifics.
- Maintain platform level performance budgets
- Support FSW and Satellite Reference Database developments
Cross-Functional Coordination, Stakeholder & Program Interaction
- Present technical status, risk analyses, and trade-study results to senior management.
- Negotiate and maintain ICDs with payload and all platform subsystems.
- Support to DC & RF harness design, Platform and Payload layout.
- Support B&P (Phase 0 & pre-phase A).
Integration & Verification (IVV)
- Author verification plans, test matrices, and validation procedures for unit, subsystem, and platform level tests.
- Coordinate, supervise or support:
- Structural vibration, acoustic & shock testing
- TCT & Thermal vacuum testing
- Power distribution functional test
- Closed-loop test on avionic testbed
- Support FSW integration
Technical Leadership & Mentorship
- Mentor, guide, lead a multidisciplinary team of junior or intermediate system engineers & interns
- Act as technical liaison with customers, partners and external vendors
- Act as Continuous Improvement stakeholder
- Contribute to MDA's knowledge-base, process enhancements, and standards development.
Configuration, Documentation & Standards Management
- Maintain platform-wide standards (structural margin, thermal-control, power-bus architecture, redundancy philosophy...etc.).
- Ensure all artefacts, analysis, software, documentations and deliverables are version controlled in PLM environment.
- Support design reviews (SRR, PDR, CDR, MRR/TRR...etc.).
- Support Technology Road-Mapping & Innovation
Launch-Site, On-Orbit & Operations Support
- Support launch-site interface checklists with LVI responsible engineer, pre-launch checkout procedures, and early-orbit checkout scripts.
- Provide real-time platform engineering support during launch, on-orbit commissioning, anomaly investigations and contingency operations.
- Support SOOH development and associated operator training.
Required Qualifications:- Sc. in Electrical Engineering, Aerospace or Physics with 5-10 years of system design experience on LEO/MEO/GEO platforms.
- Deep knowledge of spacecraft bus subsystems and their interactions.
- Experience with power-electronics design and high-precision attitude-control hardware.
- 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 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).
Comments/Special Considerations:Successful candidates must obtain and hold
security clearance at the reliability status level, and pass security assessment for the
Controlled Goods Program (CGP).
