Core Responsibilities

Primary Functions

Architect, implement, and maintain robust, scalable, and high-performance code for core gameplay systems, including player controls, character movement, and combat mechanics.
Translate complex game design documents and creative concepts into fully functional and polished in-game features.
Collaborate closely within a multidisciplinary team of designers, artists, and producers to brainstorm, prototype, and iterate on new gameplay ideas and mechanics.
Write clean, efficient, maintainable, and well-documented code in C++ (for Unreal Engine) or C# (for Unity) following established coding standards and best practices.
Develop and maintain artificial intelligence (AI) systems for non-player characters (NPCs), including pathfinding, decision-making, and behavioral logic.
Implement and fine-tune character animation systems, working with state machines, blend trees, and inverse kinematics (IK) to create fluid and believable character motion.
Profile, debug, and meticulously optimize game performance across multiple platforms (PC, Console, Mobile) to hit target frame rates and memory usage.
Design and integrate user interface (UI) components, including heads-up displays (HUDs), menus, and inventory systems, ensuring they are responsive and user-friendly.
Develop and support the networking infrastructure for real-time multiplayer gameplay, addressing issues of latency, synchronization, and state replication.
Create and extend custom tools, editor scripts, and plugins within the game engine to enhance the content creation pipeline for both engineers and artists.
Actively participate in code reviews, providing and receiving constructive feedback to maintain a high standard of code quality and team knowledge.
Integrate and manage third-party services and SDKs for functionalities such as analytics, achievements, in-app purchases, and social features.
Work with the physics engine to implement realistic object interactions, environmental effects, and dynamic gameplay elements.
Develop and maintain the game's save/load systems, ensuring player progression and game state are handled reliably.
Implement audio systems, hooking up sound effects, ambient audio, and dynamic music cues to gameplay events for a more immersive experience.
Author and maintain detailed technical design documents to guide development and serve as a reference for future work.
Port and adapt existing game code and systems to new platforms, carefully handling the unique hardware constraints and software requirements of each.
Stay informed on cutting-edge technologies, new engine features, and emerging trends within the video game industry to drive innovation.
Work hand-in-hand with the Quality Assurance (QA) team to systematically identify, reproduce, and resolve complex bugs and technical issues.
Implement rendering features and write custom shaders to achieve unique visual styles and graphical effects as defined by the art direction.
Manage and maintain build systems and continuous integration pipelines to ensure the game can be reliably built and deployed for testing.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis related to player behavior and game performance.
Contribute to the organization's technical strategy and engine roadmap.
Collaborate with business units to translate data needs into engineering requirements.
Participate in sprint planning, retrospectives, and other agile ceremonies within the development team.
Mentor junior developers, sharing knowledge and providing guidance on technical challenges and best practices.
