Real-Time 3D Simulation Engineer for Defense AI

Helsing; Paris; On-site; EUR 90,000 - 120,000; Full time

Job summary

Helsing is seeking engineers to build and maintain a large-scale, real-time simulation platform. You will model vehicles and actors, integrate high-fidelity domain models, and connect sensor environments within a distributed system.

You will translate mission requirements into reusable simulation models, write production code, and collaborate across teams to deliver impactful results in defence AI projects.

Qualifications

• Built real simulations beyond toy projects using game engines like Unreal, Unity, Godot.
• Write production code with proper software engineering discipline.
• Reason about fidelity vs throughput in simulation workloads.
• Translate domain expert input into models and behaviours for sims.
• Judge simulations by outcome, not only passing tests.

Responsibilities

• Build and maintain simulation platform internals: architecture, replication, multiplayer, profiling, interfaces.
• Assemble simulated platforms from sensor, communications, situational awareness, effector, and control-loop models.
• Balance fidelity, throughput and cost; validate with experts and tests.
• Integrate 3D models, animations, and effects from Content Engineers into the simulation.
• Investigate simulation bugs to align with reference models.
