Role Overview

We are seeking an experienced Senior Unreal5 Engineer to help architect and lead development of a next-generation UFC-style fighting game. You will help define the projects technical vision and drive delivery of performant visually stunning and highly responsive combat gameplay across console and PC platforms.

This role blends hands-on engineering requiring deep Unreal expertise strong architectural instincts and a passion for combat gameplay fidelity animation physics and multiplayer experiences.

Core Responsibilities

Technical Leadership

• Help Define and maintain the technical architecture for all game systems tools and pipelines.

• Help define the engineering roadmap aligning milestones with production and design goals.

• Partner with Art Design and Production leadership to define content pipelines and asset standards.

• Evaluate and integrate cutting-edge UE5 features (Nanite Lumen Chaos Control Rig Motion Matching).

• Set and enforce performance stability and memory budgets for console and PC SKUs.

• Drive adoption of AI-driven animation blending motion matching and advanced combat systems.

Hands-On Engineering

• Architect and prototype core systems in C and Blueprints.

• Implement deterministic combat loop rollback networking and animation blending layers.

• Collaborate with designers and animators to ensure combat feel and responsiveness.

• Integrate and optimize AI/ML runtime inference (ONNX Runtime PFNNs) for real-time motion.

• Establish CI/CD pipelines Perforce branch strategy and automated build systems.

Cross-Team Collaboration

• Work with Art/Animation teams to optimize performance for Nanite/Lumen and animation streaming.

• Partner with Design to translate gameplay concepts into efficient technical systems.

• Collaborate with QA and DevOps for automated testing performance tracking and telemetry.

Required Qualifications

• 10 years professional experience in game development with 5 years in Unreal Engine (UE4/UE5).

• Shipped at least one AAA title as a Lead or Technical Director.
