Location: Canada; United States The Satellite-Level Verification and Validation (V&V) Engineer focuses on the highest tier of spacecraft integration, ensuring the fully assembled satellite meets all mission, launch provider, and environmental requirements. Role Overview This role manages the end-to-end verification lifecycle at the highest tier of architecture. It starts at the beginning of the program with verification planning and test methodology design, continues through full-system functional and environmental validation, and concludes with final qualification sign-off and in-orbit initialization readiness. Key Responsibilities & Tasks Verification Architecture & Matrix Ownership: Define the global verification strategy; author the System Verification Plan (SVP) and own the master Verification Control Matrix (VCM) to prove 100% requirement compliance. Method of Compliance (MoC) Definition: Determine the optimal, most cost-effective blend of Verification by Test, Analysis, Demonstration, and Inspection (TADI) for complex mission-level requirements. End-to-End Mission Validation: Design and execute full-system functional tests, "Day-in-the-Life" (DITL) mission simulations, and complex Fault Detection, Isolation, and Recovery (FDIR) validation scenarios. Environmental & Launch Qualification: Define test profiles, pass/fail criteria, and post-test correlation frameworks for full spacecraft environmental campaigns (Thermal Vacuum, Sine-Vibe, Acoustic, Shock). Sign-off & Qualification Review: Lead Technical Review Boards, manage non-conformance reports (NCRs), present compliance evidence at Qualification Reviews (QR), and build the final Flight Readiness data package. Candidate Prerequisites ("Must Haves") Experience: 5+ years in aerospace systems engineering, systems V&V, or space mission qualification roles. Systems Engineering Mastery: Deep understanding of how platform subsystems and digital/RF payloads interact to satisfy top-level mission performance metrics. Requirements Management: Expert-level capability in tracing, decomposing, and closing out complex requirements using enterprise tools like DOORS, Jama, or Windchill. Data Synthesis & Analysis: Advanced skills using Python or MATLAB to parse multi-subsystem telemetry, correlate test data with analytical models, and automate post-test verification reporting.

Location: Canada; United States The Platform Systems Verification and Validation (V&V) Engineer focuses on the satellite bus, ensuring the core infrastructure subsystems are fully verified and ready to support the payload. Role Overview This role focuses on the functional verification of the utility subsystems that keep the satellite alive and oriented. It ensures the core platform—including power, thermal control, propulsion, and pointing—operates flawlessly and responds correctly to the onboard flight software. Key Responsibilities & Tasks Bus Subsystem Verification: Test and validate critical platform subsystems, including Attitude Determination and Control (ADCS), Electrical Power Subsystems (EPS), Thermal Control (TCS), and Propulsion. Hardware-in-the-Loop (HIL): Utilize HIL testbeds to simulate orbital dynamics and sensor inputs (star trackers, GPS, sun sensors) to verify ADCS pointing accuracy. Power & Harness Validation: Perform power budget verification, battery charge/discharge cycle testing, and solar array simulator (SAS) integration. Flight Software (FSW) Interfacing: Test command routing, telemetry packet generation, and fault detection, isolation, and recovery (FDIR) loops. Subsystem Interface Control: Verify that all physical, data (CAN, SpaceWire, RS-422), and electrical interfaces between platform subsystems are compliant. Candidate Prerequisites ("Must Haves") Experience: 5+ years verifying aerospace subsystems, embedded robotics, or satellite platform architectures. Technical Breadth: Strong knowledge of power electronics, orbital mechanics, thermal management, or control systems. Simulators & Automation: Experience with automated test scripting (Python/MATLAB) to control power supplies, loads, and simulated sensor inputs. Protocol Expertise: Familiarity with space-industry data protocols and avionics testing architectures.
