Core Responsibilities

Primary Functions

Design, implement and maintain game features, mechanics and systems within Unity – including gameplay logic, UI, animations, physics and player interaction.
Translate design documents and creative concepts into functional game modules, prototypes and full features, iterating based on feedback and playtesting.
Collaborate with artists, designers and sound engineers to integrate assets, materials, animations, effects and audio into the Unity game environment while ensuring quality and performance.
Optimize game performance across platforms (mobile, PC, console, VR/AR) including memory management, framerate, rendering pipeline, asset loading, and platform‑specific constraints.
Build and maintain reusable, modular and scalable code using Unity’s scripting API (C#), employing clean architecture, design patterns and best practices.
Maintain and extend the Unity engine workflows, tools, and editor extensions (custom inspectors, editor scripts) to improve developer productivity and pipeline efficiency.
Work with the production team to schedule, estimate, and deliver tasks on time, participate in agile processes (sprint planning, stand‑ups, retrospectives) and communicate status to stakeholders.
Engage in continuous testing, debugging, troubleshooting and root‑cause analysis of technical issues, crashes, bottlenecks or regressions in the game builds.
Support build, packaging and deployment of game builds across platforms including mobile app stores, console certification pipelines, or VR platform releases.
Work on multiplayer, networked game features or services where applicable: implement client‑server communication, sync logic, matchmaking, network optimisation and latency handling.
Create technical documentation (feature specs, architecture diagrams, code comments, asset pipeline documentation, run‑books) to support maintainability and team knowledge.
Keep track of emerging technologies and gaming industry trends (AR/VR, real‑time rendering, DOTS, ECS, shader programming) and propose ways to adopt them in game development.
Mentor and guide junior developers on the team: review code, share best practices, coach gameplay scripting and asset integration workflows.
Maintain code versioning, integrate with source‑control systems (e.g., Git), implement automated testing (unit, integration, play‑mode tests) and support CI/CD pipelines for game builds.
Manage game asset pipelines: collaborate with art/content teams to optimise mesh/texture assets, handle memory budgets, compression, LODs and ensure smooth runtime delivery.
Implement user interface screens, HUDs, menus, transitions, animations and visual feedback systems within Unity to deliver intuitive UX.
Participate in live‑service post‑launch support: monitor game health, analytics, crash/fault reporting, gather player feedback, implement patches and feature updates.
Collaborate with QA and designers to conduct play sessions, balance game mechanics, tune systems and ensure the final experience meets quality standards.
Liaise with production, business and marketing teams to align game features with user‑engagement metrics, monetisation goals and release milestones.
Lead or contribute to prototyping new gameplay mechanics or technologies, assess feasibility, create proof‑of‑concepts and refine production‑ready implementations.

Secondary Functions

Support ad‑hoc analytics requests, instrumentation of player metrics, telemetry events, crash logs or usability data to inform the development roadmap.
Contribute to the game development strategy and pipeline improvements, suggest workflow enhancements and process optimisations for the Unity team.
Collaborate with business units (marketing, live‑ops, analytics) to translate product/market requirements into technical tasks and prioritise accordingly.
Participate in sprint planning, daily stand‑ups and retrospectives within the game development team to help manage and deliver work‑in‑progress.

Required Skills & Competencies

Hard Skills (Technical)

Proficient in Unity engine development and C# scripting, with solid object‑oriented programming skills.
Strong understanding of game architecture, data structures, algorithms, performance optimisation, multi‑threading or concurrency patterns.
Experience with 2D and/or 3D game development including asset pipelines, rendering, lighting, physics systems, animations, particles, shaders.
Familiarity with build/upload processes for multiple platforms (mobile iOS/Android, PC, console, VR/AR) and platform‑specific constraints.
Knowledge of performance profiling and optimisation using Unity’s profiling tools and other instrumentation (GPU/CPU, memory, draw‑calls).
Experience with version control (Git, SVN) and automated testing, build pipelines (CI/CD) for game development.
Strong communication & collaboration skills to work with multidisciplinary game teams (designers, artists, audio, backend engineers) and deliver cohesive game systems.
Ability to debug and troubleshoot complex issues in game environments: engine glitches, memory leaks, performance drops, platform bugs.
Understanding of UI/UX implementation in games: HUDs, menus, animation, user flows and responsiveness across devices.
Familiarity with game monetisation features, analytics instrumentation, telemetry, player metrics and iteration based on user feedback.

Soft Skills

Excellent verbal and written communication: able to convey technical solutions, collaborate with cross‑discipline teams and present ideas clearly.
Strong problem‑solving and analytical mindset: anticipate technical risks, identify bottlenecks and propose proactive solutions.
Ownership and accountability: take responsibility for features from concept through to live operations, debug, optimise and maintain.
Team‑player and mentor: support colleagues, conduct peer reviews, share knowledge, elevate team performance.
Adaptability and continuous learning: stay current with Unity features, game‑dev trends, new platforms and drive innovation.
Time‑management and prioritisation: manage multiple features, iterations, bug‑fixes and releases under tight deadlines.
User‑centric thinking: understand player behaviour, feedback loops and prioritise improvements for engagement, retention and fun.
Quality‑oriented: deliver maintainable, testable, efficient code rather than quick fixes; favour long‑term architecture and stability.
Creativity and innovation: bring new ideas to gameplay systems, mechanics, tools or pipeline enhancements that elevate game quality.
Strategic mindset: align development efforts with business goals (monetisation, virality, metrics), make data‑driven trade‑offs and escalate architecture direction when needed.
