Job description

Specific Job Description

The 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 flexible 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 experience

Core Software Engineering Skills

• Proficient in C#, with consistent attention to code clarity, structure, and testability
• Experience developing within Unity, including scripting, scene organization, and runtime behaviour
• Strong understanding of data structures, algorithms, and computational tradeoffs relevant to interactive applications
• Ability 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 Development

• Working knowledge of render loops, update cycles and event‑driven systems
• Understanding 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, and numerical precision

System Integration

• Experience connecting a real‑time front‑end application to an external system or service layer
• Familiarity with message‑based or event‑driven communication patterns (publish/subscribe, asynchronous messaging)
• Ability to design and maintain a clean interface between visualisation layers and underlying system logic
• Understanding of data synchronisation, latency considerations, state consistency across system boundaries
• Experience diagnosing issues in distributed or multi‑component systems
• Experience with handling runtime configuration, dependencies, and environment constraints.

General Requirements

• Possess a Bachelor’s degree from an accredited university in electrical, computer or a related engineering field, mathematics, or computer science
• 3‑5 years of relevant professional experience
• Equivalent experience/combined education will be considered
• Demonstrated experience working in a multi‑disciplined, fast‑paced team environment
• Ability to communicate effectively with technical and non‑technical members of the engineering/management staff and personnel assigned to related work
• Aptitude for solving challenging problems in a team environment
• Have a high degree of initiative and autonomy
• Ability to adapt and perform in a dynamic environment
• Ability to obtain NATO Secret clearance in a timely manner.

Desired skills, qualifications and experience

• Experience with air-gapped networks
• Experience in defence industry
• Advance knowledge of object‑oriented programming
• Experience with Experience API (xAPI) or Learning Record Stores (LRS)
• Understanding of how learning or simulation data can be structured for interoperability and replayability.
