Core Responsibilities

Primary Functions

Architect, implement, and meticulously debug core gameplay mechanics, player control systems, and complex character behaviors using C++ or C#.
Collaborate in a dynamic, multidisciplinary team environment with designers and artists to translate design documents into fully functional, polished, and engaging gameplay features.
Develop and maintain a robust, scalable, and highly efficient codebase for intricate game systems within industry-standard engines like Unreal Engine or Unity.
Proactively identify and resolve performance bottlenecks across multiple platforms (PC, console, mobile), focusing on CPU, GPU, and memory optimization to ensure a smooth player experience.
Implement and refine user interface (UI) elements, including heads-up displays (HUDs), menus, and in-game feedback systems, to ensure they are responsive and intuitive.
Integrate and manage essential third-party SDKs and APIs for critical features like online multiplayer, achievements, analytics, and platform-specific services (e.g., Steam, PSN, Xbox Live).
Write exceptionally clean, well-documented, and maintainable code that consistently adheres to the team's established coding standards and software development best practices.
Design, develop, and continuously improve Artificial Intelligence (AI) systems, including pathfinding algorithms, advanced decision-making logic, and behavior trees for non-player characters (NPCs).
Implement complex physics-based mechanics, interactions, and simulations to contribute to a believable and dynamic game world.
Rapidly prototype new gameplay concepts and interactive systems to rigorously test for fun factor, technical feasibility, and alignment with the project's creative direction.
Actively participate in thorough code reviews to both provide and receive constructive feedback, fostering a culture of high code quality and shared knowledge across the programming team.
Create and maintain a suite of custom debugging tools and development utilities designed to enhance the workflow and efficiency of the entire development team.
Work closely with animators and technical artists to implement character animation systems, state machines, and visually stunning particle and shader effects (VFX).
Design and implement resilient multiplayer networking architecture, including client-server and peer-to-peer models, to support compelling and stable online gameplay.
Execute the porting and adaptation of the game's codebase to run effectively and efficiently on a diverse range of hardware configurations and target platforms.

Secondary Functions

Provide expert technical support to the Quality Assurance (QA) team to help identify, reproduce, and resolve complex or elusive engine-level bugs.
Author and maintain detailed technical design documentation that clearly outlines system architecture and implementation strategies for new and existing features.
Continuously research and stay current with the latest industry trends, programming techniques, and technological advancements to drive innovation within the team.
Mentor junior programmers and interns by providing technical guidance, code-review feedback, and support for their professional growth.
Collaborate with audio designers and engineers to implement dynamic and immersive sound systems, including contextual sound effects, music cues, and 3D spatial audio.

Required Skills & Competencies

Hard Skills (Technical)

Expert-level proficiency in modern C++ and/or C#, the cornerstone languages of contemporary game development.
Deep, hands-on experience with major game engines such as Unreal Engine (including Blueprints) and/or Unity.
A strong and intuitive grasp of 3D math, linear algebra, and physics principles as they directly apply to game development challenges.
Demonstrable ability in game performance optimization, including the use of profiling tools to analyze and improve CPU, GPU, and memory usage.
Proficiency with version control systems, primarily Git or Perforce, within a collaborative, multi-developer team environment.
Solid understanding of software architecture patterns, advanced data structures, and algorithms tailored for high-performance game systems.
Practical experience with multiplayer networking concepts, including replication, latency compensation, and client-server synchronization.
Familiarity with console development environments and their associated SDKs/TDKs (e.g., for PlayStation, Xbox, Nintendo Switch).

Soft Skills

Exceptional analytical and creative problem-solving skills, with the ability to debug complex, interdependent systems under pressure.
Excellent verbal and written communication skills, enabling clear collaboration with non-technical disciplines like art, design, and production.
A genuine passion for playing and making video games, coupled with an innate understanding of what makes a game fun and compelling.
High degree of adaptability and a proactive willingness to learn new tools, languages, and technical paradigms as projects evolve.
Strong time management and organizational abilities, with a proven track record of meeting deadlines in a fast-paced, iterative development cycle.
