Career Opportunity and Primary Roles / Responsibilities

We are seeking a Spacecraft EMC Systems Engineer for its high‑performance spacecraft for our remote sensing and communications satellites. The Spacecraft EMC Systems Engineer will own the EMC concept, analysis, verification and mitigation for multiple satellite programmes, driving architecture decisions, leading cross‑disciplinary teams. He will ensure all electrical‑subsystem on the bus and payload, from requirements capture to hardware design, do not interfere with themselves or launch vehicles. The role works closely with platform and payload teams to ensure an electrically clean, reliable and launch‑ready spacecraft.

Tasks summary:

EMC Architecture Concept & Requirements

• Capture, allocate and trace EMC functional, performance, and requirements.

• Define the EMC architecture (shielding strategy, grounding scheme, antenna placement, mode‑control, and harness segregation requirements & routing constraints).

EMC Analysis & Electrical Design

• Perform EMC analyses of the whole spacecraft (accounting for the payload specifics) for radiated/conducted emission and susceptibility, antenna coupling, shielding effectiveness, fuse blowing…etc. and verify compliance early in the design cycle.

• Recommend mitigation such as shielding, filtering, grounding schemes, layout rules.

DC Power Distribution

• Review DC power distribution architecture (primary bus, secondary bus lines, converters, fusing, protection) for EMC/EMI aspects.

• Review conductors, termination, connectors and back shells (material, gauge, shielding…etc.) that satisfy EMI control requirements.

Cross‑Functional Coordination, Stakeholder & Program Interaction

• Communicate technical status, risk assessments and trade‑study results to senior management and/or customers or partners.

• Support ICDs with payload and platform teams and suppliers.

• Act as the EMC authority in System and subsystem design reviews

• Liaise with RF, Power, Structures, Propulsion, Software and Ground‑Segment teams to resolve cross‑disciplinary EMC issues early.

• Support B&P (Phase 0 & pre-Phase A).

Integration & Verification (IVV)

• Author the EMC Verification Master Plan covering component level, subsystem level and full spacecraft tests (CE/CS, RE/RS).

• Oversee test‑facility set‑up, instrumentation calibration, test execution, data reduction and results certification.

• Author test procedures, and acceptance criteria.

• Lead CE/CS tests, RE/RS tests on hardware and review suppliers test results.

Technical Leadership & Mentorship

• Mentor, guide junior engineers and interns and provide EMC training sessions.

• Act as technical liaison with customers, partners and external vendors.

• Act as Continuous Improvement stakeholder.

• Contribute to knowledge‑base, process enhancements, and standards development.

Configuration, Documentation & Standards Management

• Participate in Change Control Boards (CCB) and ensure impact analyses are performed for any electrical change.

• Maintain GDIR and EDTS streamlining.

• 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 root‑cause investigations for on‑orbit anomalies; update design baselines and lessons‑learned.

• Support SOOH development and associated operator training.

Required Qualifications:

• B.Sc. in Electrical Engineering, Aerospace or Physics, (M.Sc. preferred) with 10 + years of electrical design engineering experience on LEO/MEO/GEO missions.

• Proficiency in spacecraft and unit EMC requirements and simulations.

• Prior experience supervising a team of EMC engineers or leading multi‑disciplinary task‑forces.

• 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 to no 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).

Miscellaneous Requirements

• This position is open only to Canadian citizens and permanent residents currently residing in the Montreal area.

• The work model is hybrid, with a requirement to work in the office four (4) days per week.

• The position may require occasional travel to visit customers in North America.

Knowledge of English is required to communicate and work with customers outside the province of Quebec. / La connaissance de l'anglais est requise pour communiquer et travailler avec nos clients situés à l'extérieur de la province de Québec.
