Role :

MDA is seeking a Digital Payload Architect to own the definition, high‑level architecture, trade‑studies and technology‑road‑mapping of digital payload subsystems across multiple satellite programs. This role is a senior technical bridge between customers, prime contractors and MDA’s multidisciplinary payload engineering teams, ensuring that the digital payload delivers the performance, reliability and cost targets per the mission objectives.

• Establish functional, performance, environmental and security requirements with mission stakeholders & CONOPs.
• Translate requirements into clear payload performance parameters and maintain bidirectional traceability throughout the project lifecycle.
• Establish with cybersecurity team payload‑specific requirements & embed resilience and security by design.
• Define the overall digital payload architecture (optical/RF ISLs, antenna arrays, digitizers/ on‑board processing, Feeder links, master reference oscillator & clock synchronizations).
• Define Interface Control Documents (ICDs) with spacecraft bus, ground segment and payload‑specific subsystems.
• Identify emerging technologies and incorporate them into MDA’s long‑term roadmap.

System Modeling & Performance Simulation

• Build end‑to‑end models of the signal chain (optical/RF, analog/digital) using MATLAB/Simulink, SystemView or Python‑based toolkits.
• Run Monte‑Carlo and tolerance analyses to verify gain, SNR, dynamic range, spectral efficiency, G/T, EIRP and other key metrics.
• Optimize payload design and performance with operation with traffic models/CONOPs.

Simulation & Analysis

• Oversee performance simulations & analysis (Gain, Spurious, Linearity, SNR, dynamic range, spectral efficiency, pointing, G/T, EIRP…etc.) and tolerance budgeting.
• Optimize Payload DC power budget with traffic & utilization models.

Hardware & Firmware

• Own system‑level specifications to hardware designers, review schematics, layouts, thermal & mechanical interfaces.
• Oversee MODCODs selection and on‑board processing pipelines; define BIST, timing, latency and deterministic behavior.

Cross‑Functional Coordination, Stakeholder & Program Interaction

• Communicate technical status, risk assessments and trade‑study results to senior management and/or customers or partners.
• Act as the primary technical liaison with Electrical, Power, Structures, Thermal, Software, Ground‑Segment and Mission‑Operations teams to resolve integration issues early.
• Support payload design authority in System design reviews and Mission Operations hand‑over.
• Support B&P (Phase 0 & pre-phase A).
• Define test‑automation framework set‑up, test‑case definition, results analysis and test‑report certification.

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 MDA’s knowledge‑base, process enhancements, and standards development.

Configuration, Documentation & Standards Management

• Ensure all artefacts, analysis, software, deliverables and documentation are version controlled in PLM environment.

On Orbit & Operations Support

• Technical support to Mission Operations for routine payload health monitoring, contingency handling and performance trending.
• Lead root‑cause investigations for on‑orbit anomalies; update design baselines and lessons‑learned.
• Analyze on‑orbit telemetry, update filter parameters, and generate performance reports.
• Define SOOH and associated operator training.

Required Qualifications:

• Sc. in Electrical Engineering, Aerospace or Physics (M.Sc. preferred) with 10 + years of digital regenerative payload system design experience on LEO/MEO missions.
• Comprehensive knowledge of digital communications, SDR, DSP, DVB RCS/SX protocols, Modulation schemes, Class of Service, Networking, MPLS, 2G, 5G,
• Strong technical‑writing ability (requirements, ICDs, test procedures, risk reports) and presentation skills; comfortable interfacing with customers, suppliers and senior leadership.
• 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).

Comments/Special Considerations:

Successful candidates must obtain and holdsecurity clearance at the reliability statuslevel, and pass security assessment for theControlled Goods Program (CGP).
