Full Job Description

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.

Key Responsibilities

Unreal Engine Development (C++ Focus)

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)

Simulation & Systems Integration

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

User Interface & Data Visualization

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

Networking & Multiplayer 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)

Simulation Features & Enhancements

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)

Required Qualifications

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)

Preferred / Differentiating Experience

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.)

What We Are NOT Looking For

Blueprint-only Unreal developers without strong C++ experience
Virtual production / film / green-screen backgrounds
3D artists, character modelers, or purely visual designers

Success Profile

The ideal candidate is a true software engineer who:

Writes production-grade C++ in Unreal
Understands real-time systems and simulation
Can integrate external data and protocols into a live environment
Is comfortable working in a complex, engineering-driven simulation ecosystem

Pay: $70.00 - $80.00 per hour
