Specific Job DescriptionThe simulation software engineer will play a key role in the evolution of an established simulation training platform contributing to the transition from a traditional desktop-based system to a modern, interactive 3D environment. Reporting within a cross‐functional engineering team, the successful candidate will be responsible for designing and implementing components that enable real-time visualization, user interaction, and system integration.Primary responsibilities include translating existing system workflows and logic into a Unity-based environment, developing scalable and maintainable application components, and ensuring alignment between the visualization layer and underlying system behaviour. This includes building and maintaining integration pathways between the front‐end application and external services, and supporting reliable data exchange.The role offers a versatile hybrid work schedule with a minimum requirement of two days per week in the office to collaborate with other software engineers, testers, graphic artists, system subject matter experts to ensure that new capabilities are introduced without compromising existing functionality. The engineer will contribute to defining practical modernization strategies, balancing performance, usability, and long‐term maintainability while supporting incremental delivery features.In addition to development activities, the candidate will participate in Agile workflows, including sprint planning, estimation, and iterative delivery. They will contribute to code reviews, technical discussions, and continuous improvement of development practices.



The engineer will also have the opportunity to take on stretch assignments that extend our business growth across multiple departments, such as supporting Internal Research and Development, establishing best‐practices and guidelines for all users, and contributing to process and tooling improvements in supporting enterprise excellence.Required skills, qualifications and experienceCore Software Engineering SkillsProficient in C#, with consistent attention to code clarity, structure, and testabilityExperience developing within Unity, including scripting, scene organization, and runtime behaviourStrong understanding of data structures, algorithms, and computational tradeoffs relevant to interactive applicationsAbility to debug issues across multiple layers (application logic, runtime behaviour, and system integration)Familiarity with version control workflows (branching, code reviews, maintaining clean history)3D/Real‐Time Application DevelopmentWorking knowledge of render loops, update cycles and event‐driven systemsUnderstanding of performance considerations in real‐time environments (frame rate, memory usage, object lifecycle)Experience implementing interactive features in 3D space (selection, manipulation, camera control, input handling)Awareness of coordinate systems, spatial transformations,
