Core Responsibilities

Primary Functions

Architect, implement, and maintain robust gameplay systems and mechanics in Unreal Engine using modern C++ standards and Unreal's API, ensuring code quality, maintainability, and performance for PC, console, and mobile platforms.
Design and author Blueprint systems and hybrid C++/Blueprint solutions that empower designers while maintaining performant, production‑ready game logic and safe editor workflows.
Implement and validate multiplayer architecture, network replication, client‑server prediction, authoritative server logic, latency compensation, and bandwidth optimization to deliver smooth online gameplay experiences.
Profile CPU, GPU, memory, and I/O bottlenecks using tools such as Unreal Insights, PIX, NSight, and platform SDK profilers; diagnose performance regressions and deliver measurable performance improvements and optimization plans.
Develop and optimize rendering features, materials, and custom shaders (HLSL/Material Editor), including work with Nanite, Lumen, translucency, and lighting systems to achieve target frame rates and visual fidelity.
Integrate and extend animation systems, animation blueprints, blendspaces, IK (inverse kinematics), retargeting, and pose handling to support complex character rigs and smooth gameplay-driven animation transitions.
Design and implement physics interactions, ragdoll systems, character controllers, constraints, and collision optimization using Chaos/PhysX or engine physics modules while ensuring stable deterministic behavior where applicable.
Build editor tools, plugins, and pipeline automation in C++ and Python to accelerate content creation, automate repetitive tasks, and improve cross‑discipline collaboration between designers and artists.
Create and maintain scalable asset streaming, level streaming/world composition, and LOD logic to balance memory footprint and streaming performance for large open worlds and seamless travel scenarios.
Implement and maintain audio, UI (UMG), and cinematics (Sequencer) integrations, ensuring that code interfaces with other subsystems in a clean, testable manner.
Lead code reviews, enforce best practices and engine coding standards, and mentor junior developers on debugging, profiling, optimization, and Unreal Engine idioms.
Collaborate cross‑functionally with design, art, QA, and product teams to scope features, estimate work, produce technical design documents, and iterate quickly based on playtest feedback.
Own crash analysis, root cause identification, and fixes for stability issues across platforms, using platform crash reporters and logs to track and resolve regressions.
Implement VFX systems and particle workflows using Niagara (and legacy Cascade when necessary), integrating particle systems efficiently into gameplay contexts and optimizing spawn and tick costs.
Author and maintain robust unit tests, integration tests, and automated build validation scripts as part of CI/CD pipelines to ensure regressions are caught early and engineering velocity remains high.
Port and upgrade code and assets between engine versions (e.g., UE4 → UE5), resolving API changes, adapting to new rendering/pathfinding/physics paradigms, and ensuring minimal disruption to production.
Design and implement tools and solutions to support live ops, hotfix deployment, telemetry, and remote configuration to enable rapid iteration and monitoring of production titles.
Collaborate with platform engineers to achieve console certification requirements, performance targets, and memory budgets for PlayStation, Xbox, Nintendo Switch, and mobile guidelines.
Optimize network serialization and replication strategies, implement prioritization and relevancy systems, and reduce bandwidth and latency impacts for competitive multiplayer features.
Maintain source control hygiene and release management workflows using Perforce or Git, manage branching strategies for large teams, and participate in release builds, patches, and content pipeline verification.
Research and prototype new engine features, middleware integrations (physics, AI, networking libraries), and emerging technologies such as VR/AR, haptics, and MetaHuman pipelines to evaluate their fit for current and future projects.
Produce clear, developer‑facing technical documentation, run knowledge transfer sessions, and keep onboarding materials up to date so new hires can be productive quickly.

Secondary Functions

Support production by responding to live‑ops incidents, hotfix rollouts, and emergency stability patches under tight deadlines while maintaining quality and traceability.
Assist QA teams by reproducing, triaging, and fixing complex bugs across platforms, and collaborate to define reliable test cases and automation to prevent regressions.
Contribute to hiring and interview cycles by conducting technical screens, evaluating candidate code samples, and providing structured feedback to recruitment teams.
Help define and refine engineering processes, CI/CD pipelines, automated performance testing, and build farm optimizations to accelerate deployment velocity.
Act as a technical liaison between engineering and external partners or middleware vendors to integrate third‑party systems, resolve issues, and negotiate feature roadmaps.
Participate in sprint planning, grooming, and agile ceremonies; help estimate scope and risk for engineering tasks and adjust priorities based on technical dependencies.
Maintain a backlog of technical debt items, propose refactors, and lead initiatives to reduce complexity, improve testability, and improve system robustness.
