Core Responsibilities

Primary Functions

Design, implement, and maintain well-architected, reliable, and extensible code for core gameplay systems, including player controls, AI behavior, game logic, and physics interactions.
Collaborate directly with game designers and artists to understand the creative vision and translate design documents and artistic requirements into fully realized, interactive gameplay features.
Develop and iterate on prototypes to test and validate new gameplay mechanics, control schemes, and user interface concepts, providing technical feedback on feasibility and scope.
Write high-performance, multithreaded code in C++ or C# within major game engines like Unreal Engine or Unity, ensuring smooth and responsive gameplay experiences.
Implement complex character and non-player character (NPC) artificial intelligence, including pathfinding, decision-making logic (e.g., behavior trees, state machines), and dynamic combat behaviors.
Architect and develop the underlying systems for multiplayer gaming, including network replication, latency compensation, state synchronization, and server-side authority.
Profile, analyze, and optimize game performance across various target platforms (PC, PlayStation, Xbox, Switch, Mobile), addressing bottlenecks in CPU, GPU, memory usage, and streaming.
Debug and resolve complex software defects, including elusive crashes, race conditions, and gameplay bugs, using debugging tools, crash dumps, and performance analyzers.
Extend and customize game engine functionality by creating bespoke tools, editor plugins, and scripts to improve the content creation pipeline and empower designers and artists.
Develop and maintain rendering features, such as custom shaders, lighting models, and post-processing effects, to help achieve the game's unique artistic style.
Implement and manage game state, player progression, and save/load systems, ensuring data integrity and a seamless user experience.
Integrate and support a wide range of third-party SDKs and middleware for systems like physics simulation (PhysX, Havok), audio engines (Wwise, FMOD), and online services.
Write clean, maintainable, and portable code that adheres to team-wide coding standards and best practices, participating in rigorous code reviews to maintain quality.
Develop and maintain user-facing systems such as UI/HUD, menu navigation, and input handling for a variety of controller types and platforms.
Work on platform-specific implementation details, ensuring the game complies with technical requirements and certification standards for consoles like PlayStation and Xbox.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis related to in-game events and player telemetry to inform design decisions.
Contribute to the technical documentation of gameplay systems, engine features, and tools to facilitate knowledge sharing within the development team.
Collaborate with QA and technical support teams to help diagnose and resolve issues reported by testers and the player community.
Participate actively in sprint planning, daily stand-ups, retrospectives, and other agile ceremonies to ensure clear communication and predictable delivery.
Mentor junior engineers, providing guidance on technical challenges, coding best practices, and navigating the complexities of the game development lifecycle.
Stay current with the latest industry trends, programming techniques, and advancements in game engine technology to drive innovation and continuous improvement.
