(Fastwater Staffing) Senior Platform Systems Engineer

Location: Montreal, Canada 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: 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 company'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).
