Satellite Bus Systems Engineer for Fastwater Staffing

Role overview:

Our client 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 our client's 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.
• Lead trade studies for structural approach, thermal control concepts (MLI, heat pipes, radiators…etc.), power generation options (e.g. solar array & battery technologies).

Concept Trade & Feasibility

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:
  • o  Structural vibration, acoustic & shock testing
• o TCT & Thermal vacuum testing
• o  Power distribution functional test
• o  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 client’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:

• B.Sc. in Electrical Engineering, Aerospace or Physics with 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).
