With over 90,000 employees worldwide, Leonardo is a global high-technology company and a key player in the international defence and security sector. Leonardo Canada Inc. (LCI) continues to grow and expand our footprint in Ottawa. We offer a dynamic and collaborative work environment where innovation is encouraged, and employees are empowered to grow professionally. Our team supports Canadian and international customers with world-leading technologies across land, air, and naval domains.

Position Summary

We are seeking highly motivated Electronic Warfare (EW) Scientists with expertise in Electro-Optical/Infrared (EO/IR) sensing technologies to support the design, development, testing, and advancement of next-generation defense simulation and electronic warfare products. As part of a multidisciplinary team of scientists, engineers, and software developers, you will contribute to the development of advanced physics-based models, algorithms, and simulation capabilities supporting military sensor, weapon, and countermeasure systems across sea, air, and land domains. This is an excellent opportunity for candidates who are passionate about EW, sensor systems, modelling and simulation, signal processing, and advanced defense technologies.

The successful candidate will:

· Design, develop, and validate software modules and algorithms using MATLAB, Simulink, and C/C++.

· Develop and maintain high-fidelity, physics-based models of Electronic Countermeasure (ECM) systems and related sensor technologies.

· Integrate EO/IR, and EW models into our simulation and training products.

· Research, model, and analyze military sensors, weapon systems, threat systems, and countermeasures.

· Improve and evolve software architectures to meet emerging customer and product requirements.

· Develop interfaces and integrations between internal products and external systems.

· Conduct verification, validation, and performance testing of mathematical models, algorithms, and software implementations.

· Create and maintain technical documentation, user guides, and modeling specifications.

· Develop expertise in EO/IR and UV-based sensing technologies, image exploitation, target detection, classification, and tracking algorithms.

· Analyze real-world system performance and generate datasets used to configure and validate simulation models.

· Support customer demonstrations, technical reviews, and defense-related analysis activities.

· Collaborate closely with software developers, systems engineers, subject matter experts, and customers to deliver high-quality solutions.
