Career Opportunity and Primary Roles / Responsibilities

We are seeking a GNC System Engineer for design, integration, verification, and operational support of GNC subsystems for our current and next‑generation remote sensing and communications satellites. The role will require to design the complete subsystem, from algorithm development through hardware implementation, verification, and on‑orbit operation support. The role requires deep expertise in orbital dynamics, attitude‑determination & control, plus real‑time FSW definition and integration, and will work closely with subsystem and mission operations teams throughout the satellite life‑cycle.

Tasks summary:

Architecture Concept & Requirements

Derive GNC functional, performance, and safety requirements (pointing accuracy, slew rate, orbit‑maintenance ΔV, fault‑tolerance) from mission level requirements.
Produce System Requirements, Interface Control document (ICD), and Description Document.
Perform requirement management and maintain bidirectional traceability throughout the project lifecycle.

Modelling & Trade‑Study

Conduct trade studies on sensor suites and actuator families.
Perform high‑fidelity dynamics simulations (Matlab/Simulink, STK) to meet pointing requirements, maintain error budgets, control‑law stability, fuel consumption, and survivability margins.

Algorithm Development

Design and implement attitude‑determination algorithms and orbit‑determination solutions.
Develop control laws for 3‑axis stabilization, slew maneuvers, station keeping algorithms
Validate algorithms with Monte‑Carlo analysis, worst‑case scenarios, and support SIL/HIL testing on avionic test bench.

Cross‑Functional Coordination, Stakeholder & Program Interaction

Translate algorithms into FSW requirements running on real‑time operating systems.
Collaborate with the C&DH and FSW teams to implement TM/TC, schedulers and FDIR logic for GNC.
Present technical status, risk analyses, and trade‑study results to senior management.
Negotiate and maintain ICDs with subsystems.
Support B&P (Phase 0 & pre-phase A).

Hardware Selection & Design

Specify sensor and actuator hardware, perform interface definition (electrical, mechanical, thermal) and conduct trade on redundancy architectures.
Work with structures and thermal engineers to ensure proper mounting, thermal paths, and vibration survivability of GNC hardware aligning with payload requirements.
Review harness routing and power distribution for GNC electronics.

Integration & Verification (IVV)

Author Verification Plans, Test Matrices, and Validation Procedures for unit, subsystem, and spacecraft level GNC tests.
Lead functional tests: sensor calibration, actuator command‑response, closed‑loop attitude‑control on testbeds, and on‑orbit checkout sequences.
Conduct failure mode and effects analysis (FMEA), fault tree analysis (FTA), and reliability prediction.

Technical Leadership & Mentorship

Mentor, guide junior engineers and interns.
Act as technical liaison with customers, partners and external vendors
Act as Continuous Improvement stakeholder
Contribute to knowledge‑base, process enhancements, and standards.

Configuration, Documentation & Standards Management

Maintain GNC standards (sensor/actuator interface, filter design, control‑law documentation).
Ensure all artefacts, analysis, software, deliverables 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 procedure developments (detumble, orbit‑maintenance, safe‑mode…etc.).
Provide real‑time GNC support during launch, early‑orbit checkout, and contingency events.
Analyse on‑orbit telemetry, update filter parameters, and generate performance reports.
Support SOOH development and associated operator training.

Required Qualifications:

B.Sc. in Electrical Engineering, Aerospace or Physics, (M.Sc. preferred), focused on flight dynamics, control theory, or navigation with 10+ of GNC/AOCS experience on LEO/MEO/GEO platforms.
Orbital mechanics, attitude dynamics, and control‑law design (classical and modern optimal control).
Proficiency with navigation sensors and actuators.
Experience implementing real‑time filtering and control algorithms in embedded code
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 verbal communications skills in English & French work environment.

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.

At MANNARINO, we believe that passion and a desire to learn is crucial. Diversity of thought and experiences leads to innovative solutions and creativity. This is why we would like to encourage all those interested to apply.

We are an equal opportunity employer. All applicants will be held in strict confidence. Only those selected for interview will be contacted.
