Model-Based Systems Engineer (MBSE) – Remote / On-site Opportunity | Fastwater Staffing

Location: Montreal, Quebec, Canada (On-site preferred; exceptional remote candidates will be considered)
Employment Type: Contract-to-Permanent (Preferred) / Contract
Work Arrangement: On-site preferred. Exceptional candidates may be considered for a fully remote arrangement.
Start Date: Immediate
Compensation: TBD -- based on skills and experience

Important Screening Requirements

Candidates must possess both of the following non-negotiable qualifications:

• Model-Based Systems Engineering (MBSE) experience, including SysML, Cameo Systems Modeler, functional decomposition, and requirements traceability.
• Launch and Early Orbit Phase (LEOP) operations experience, including spacecraft commissioning and/or routine satellite operations.

Please note: Candidates who do not have both MBSE and LEOP experience will not be considered.

• Montreal/on-site remains the preferred work arrangement.
• Exceptional candidates may be considered for a fully remote arrangement. Remote candidates must demonstrate significantly stronger MBSE expertise and satellite operations experience than on-site candidates.

About the Role

We are seeking an experienced Model-Based Systems Engineer (MBSE) to support the development of advanced satellite systems through modern digital engineering practices. In this role, you will develop and maintain system architectures, create model-based engineering artifacts, and ensure end-to-end requirements traceability while supporting spacecraft commissioning and operations during the Launch and Early Orbit Phase (LEOP). The ideal candidate has a strong background in satellite systems engineering, MBSE methodologies, and mission operations, with the ability to collaborate across multidisciplinary engineering teams.

Key Responsibilities

• Develop and maintain system architectures using Model-Based Systems Engineering (MBSE) methodologies.
• Create and manage SysML models using Cameo Systems Modeler.
• Perform functional decomposition and maintain end-to-end requirements traceability.
• Support digital engineering initiatives throughout the system development lifecycle.
• Develop and maintain Concept of Operations (CONOPS) documentation and system behavior models.
• Support spacecraft commissioning and Launch and Early Orbit Phase (LEOP) activities.
• Collaborate with systems, software, hardware, integration, and operations teams to ensure mission readiness.
• Participate in architecture reviews, engineering trade studies, and technical design reviews.
• Support systems integration, verification, validation, and operational readiness activities.
• Prepare engineering documentation and communicate technical recommendations to stakeholders.

Required Qualifications

• Demonstrated experience with Model-Based Systems Engineering (MBSE).
• Hands-on experience with:
  • SysML
  • Cameo Systems Modeler
  • Functional decomposition
  • Requirements traceability
• Experience supporting Launch and Early Orbit Phase (LEOP) operations.
• Experience with spacecraft commissioning and/or routine satellite operations.
• Strong understanding of systems engineering principles and digital engineering methodologies.
• Excellent analytical, problem-solving, communication, and collaboration skills.
• Ability to work effectively in multidisciplinary engineering teams.

Preferred Qualifications

• Experience developing Concept of Operations (CONOPS) documentation.
• Experience supporting LEO/MEO satellite systems or spacecraft development programs.
• Familiarity with digital engineering frameworks and MBSE best practices.
• Experience with satellite mission planning, systems integration, and spacecraft operations.
• Experience leading systems engineering trade studies and architecture reviews.

What We're Looking For

We're looking for an exceptional Model-Based Systems Engineer who combines deep MBSE expertise with real-world satellite operations experience. The ideal candidate has successfully applied SysML and Cameo Systems Modeler to develop robust system architectures while supporting spacecraft commissioning and LEOP activities. You are a collaborative systems thinker who can translate complex mission requirements into well-structured system models and deliver practical engineering solutions across the satellite lifecycle.

Montreal-based, on-site candidates remain the preferred choice. However, truly exceptional candidates with outstanding MBSE and satellite operations experience may be considered for a fully remote arrangement. Candidates with both MBSE and LEOP experience will be given the highest priority, as these are mandatory qualifications for the role.
