Unreal Engine C++ Developer

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: $90.00 - $100.00 per hour

Experience:

Unreal Engine: 4 years (Required)

C++: 8 years (Required)

Ability to Commute:

St. Louis, MO 63177 (Required)

Work Location: Hybrid remote in St. Louis, MO 63177
