Unreal Engine C++ Developer

Job Title:

Unreal Engine C++ Developer

Location:

St. Louis (Hybrid 2-3 days onsite)

We are supporting a flight simulation and pilot training initiative focused on high-fidelity mission visualization and real- time simulation environments.

This role is for a software engineer specializing in Unreal Engine (C++), not a designer or artist. The developer will be responsible for implementing core simulation logic, system integrations, and real- time application functionality to support training, sensor visualization, and mission scenarios.

• Develop and implement application logic using Unreal Engine with C++ (not Blueprint-only)

• Load and manage DLC/plugins containing large 3D asset libraries (aircraft, naval systems, civilian models, etc.)

• Optimize and manage rendering of large- scale environments and dynamic assets

• Implement level-of-detail logic (e.g., converting MASS entities to full actors based on range/visibility)

• Implement and integrate simulation protocols including:

  • DIS (Distributed Interactive Simulation)

  • CIGI (Common Image Generator Interface)

  • OMS (Open Mission Systems)

• Use protocol inputs to drive:

  • Actor positioning

  • Animation triggers

  • Real- time simulation behavior

• Support proof-of-concepts and production implementations for simulation interoperability

• Develop UI components to support:

  • Sensor data visualization

  • Lat/Lon grid overlays on 3D globe environments

  • User selections and highlighting

• Implement multiple camera modes (e.g., cinematic, tracking, cockpit perspectives)

• Build integrations to:

  • Export simulation data to external data science platforms

  • Consume input from external remote control/configuration systems

• Implement Unreal Engine networking features:

  • Multiplayer replication

  • State synchronization across multiple simulation instances

• Support real- time, synchronized simulation environments (e.g., multi- cockpit scenarios)

• Contribute to development of advanced simulation capabilities including:

  • Photogrammetry-based environments and 3D terrain (Cesium)

  • Building and infrastructure data integration

  • IR (infrared) sensor simulation and dynamic material responses

  • SAR (synthetic aperture radar) simulation

  • Weather systems and synchronized multi-environment conditions

  • Time-of- day and control integrations (e.g., HOTAS via CIGI)

• Enhance realism and fidelity (lighting, shadows, materials, environmental effects)

• Must be a U.S. citizen

• 3+ years of hands- on experience with Unreal Engine development using C++

• Strong proficiency in C++ programming

• Experience building interactive, real- time 3D applications

• Understanding of:

  • Game engine architecture

  • Actor systems and scene management

  • Performance optimization in real- time environments

• Ability to work as a software engineer (not a 3D artist or designer)

• Experience with simulation standards:

  • DIS, CIGI, OMS (or similar)

• Background in:

  • Aerospace, defense, or simulation environments

  • Real- time data integration or visualization

• Familiarity with:

  • Unreal networking and multiplayer systems

  • Sensor simulation or physics-based modeling

  • Large- scale geospatial environments (Cesium, GIS, etc.)
