Core Responsibilities

Primary Functions

Design, develop and implement core game mechanics, systems and features (physics, user‑interaction, UI, AI, game logic) ensuring gameplay aligns with creative vision.
Write clean, efficient, maintainable and tested code (C++, C#, Java, scripting languages) for game engines and platforms.
Collaborate with game designers, artists and sound engineers to integrate visuals, animations, audio, and asset pipelines into real‑time interactive environments.
Optimise game performance across platforms (mobile, console, PC), manage memory, frame rate, rendering, asset streaming and hardware constraints.
Develop and maintain game engine components, extend engine functionality, build tools, editor extensions and automation to improve development productivity.
Participate in the full game development lifecycle: concept, prototype, build, test, deploy and post‑launch live operations.
Implement multiplayer or networked game features when required: client/server architecture, matchmaking, latency optimisation, synchronization and backend service integration.
Conduct system and gameplay debugging, troubleshoot complex issues, perform root‑cause analysis, fix bugs and deliver patches or updates in live‑game environments.
Create and maintain technical documentation: design specs, architecture diagrams, code comments, release logs and run‑books to ensure future maintainability.
Lead or participate in agile development processes (sprint planning, stand‑ups, retrospectives), estimate tasks, prioritise features, manage dependencies and collaborate on delivery.
Work closely with QA and testing teams to design and execute test plans (unit, integration, performance, compatibility) and refine gameplay based on feedback.
Maintain and implement asset and content pipelines: collaborate with artists to ensure assets (2D/3D models, animations, textures) are optimized for runtime.
Stay updated with industry trends, new tools, engines, platforms (VR/AR, consoles, mobile) and propose adoption of new technologies or design approaches.
Balance gameplay systems (difficulty, pacing, progression, economy) based on player feedback, analytics and play‑testing results to ensure user engagement.
Ensure the game aligns with business objectives: monetisation, user‑retention, live‑service updates, platform releases and global launch strategy.
Manage version control systems, branching strategies, build systems, continuous integration/deployment workflows in a game‑engineering environment.
Mentor junior developers: provide code reviews, share best practices, contribute to team growth and maintain engineering culture.
Monitor game analytics, crashes, player behavior, performance metrics and feed insights into the development roadmap and post‑launch improvements.
Collaborate across disciplines (design, UI/UX, audio, production, marketing) to ensure cohesive game experience, launch readiness and alignment with brand vision.
Maintain commitment to game quality: polish gameplay, ensure stability across platforms, manage release readiness, submission to console stores and certifications.

Secondary Functions

Support ad‑hoc data requests and exploratory analytics for in‑game events, player behaviour, telemetry or feature usage.
Contribute to the organisation’s game‑technology roadmap, toolchain improvements and development process enhancements.
Collaborate with business units (marketing, live‑ops, analytics, user‑acquisition) to translate player data and feature requests into engineering deliverables.
Participate in sprint planning, backlog refinement, and agile ceremonies within cross‑functional game development teams.

Required Skills & Competencies

Hard Skills (Technical)

Proficiency in one or more game development languages (C++, C#, Java) and object‑oriented programming.
Experience with game engines such as Unity, Unreal or equivalent, including scripting, asset integration, engine extensions and tool development.
Strong understanding of real‑time rendering pipelines, graphics (2D/3D), physics systems, animation integration and asset optimization.
Experience building and integrating user interfaces, HUDs, menus, game UX flows and working with UI/UX designers.
Knowledge of multiplayer/networking, client/server architecture, real‑time communications, latency and scalability.
Proficiency in debugging, profiling, performance optimisation, memory management and ensuring stable performance across platforms.
Familiarity with version control systems (Git/SVN), build tools, CI/CD pipelines and release processes for game development.
Ability to work across multiple platforms: mobile, PC, console, VR/AR and ensure cross‑platform compatibility and performance.
Strong documentation skills: ability to author technical specs, run‑books, architecture diagrams and code documentation.
Experience with analytics instrumentation, telemetry, player metrics and translating data into gameplay or system improvements.

Soft Skills

Excellent communication: ability to convey technical concepts clearly to designers, artists, stakeholders and cross‑functional teams.
Creative problem‑solving: ability to break down complex game features, identify issues, propose elegant solutions and iterate quickly.
Collaboration and teamwork: works well in multi‑discipline teams and fosters a shared vision of game experience.
Ownership and accountability: responsible for feature quality, system performance and end‑to‑end delivery of game components.
Adaptability and continuous‑learning: embraces new technologies, platforms and development methodologies in the evolving games industry.
Mentorship and leadership: supports junior team members, promotes best practices and contributes to a culture of excellence.
Time‑management and prioritisation: manage multiple tasks, bugs, feature requests and deadlines effectively in a fast‑paced production environment.
User‑focus: keeps the player experience, usability, immersion and fun at the centre of engineering efforts.
Quality mindset: insists on clean, testable, maintainable code, polished gameplay and stable releases rather than quick patches.
Strategic thinking: aligns game development work with broader business goals, player retention, monetisation and live‑services strategy.
