Core Responsibilities

Primary Functions

Design, implement and maintain reusable, efficient, and reliable code within Unity (C#, assemblies, editor scripts) to drive application features and gameplay systems.
Translate game design, storyboards, prototypes and UI/UX specifications into executable interactive experiences across platforms (mobile, PC, console, VR/AR).
Collaborate with artists, animators, technical artists, audio engineers and designers to integrate assets (models, textures, animations, sound) and ensure seamless workflows.
Optimize performance across platforms: identify bottlenecks, reduce CPU/GPU load, manage memory usage, frame rate targets, latency issues and ensure smooth user experience.
Conduct rigorous debugging, identify and fix defects, manage asset pipelines, editor tools, build configurations and ensure code quality and stability.
Develop editor tools, custom scripts, editors, inspectors and workflows that support the art/design teams and accelerate production in Unity.
Architect and implement game systems including physics, animation, UI, network/multiplayer features, persistence, input handling and platform‑specific integrations.
Manage cross‑platform deployment: configure build settings, manage SDKs, deal with platform quirks (iOS, Android, Windows, consoles), package and deliver release builds.
Lead code reviews, maintain coding standards, enforce design patterns, document APIs, contribute to technical documentation and promote best practice across the team.
Stay current with Unity engine updates, tools, plugins, render pipelines (URP/HDRP), AR/VR integrations, and propose adoption of new capabilities to improve product quality.
Participate in sprint planning, agile workflows, backlog grooming, estimation, stand‑ups and contributor to continuous integration/continuous deployment (CI/CD) processes for Unity projects.
Implement automated testing frameworks for Unity builds: unit tests, integration tests, automated QA, performance tests, regression suites and support build pipelines.
Monitor game analytics, user feedback, telemetry and key performance indicators (KPIs), iterate on features, and improve user engagement, retention and monetization.
Create technical prototypes to evaluate new mechanics, user interactions, optimization techniques or architecture changes and evaluate feasibility for production.
Ensure accessibility, localization and platform compliance: implement multi‑language support, handle localization assets, support accessibility standards and device/locale variations.
Support live‑operations post‑release: manage patching, hot‑fixes, content updates, asset bundles, live events, remote content delivery and version‑control of live builds.
Work with backend engineers to integrate multiplayer backends, cloud services, leaderboards, analytics SDKs, social features and ensure end‑to‑end functionality from Unity UI to backend.
Mentor junior developers, provide technical guidance, lead feature teams, enforce architecture decisions and build team technical capability around Unity.
Ensure cross‑discipline collaboration: work with UI/UX, QA, product managers and marketing to align feature implementation with business goals, branding, user experience and launch timelines.
Document and maintain asset versioning, project build pipelines, branch strategies, release notes, roll‑back procedures and coordinate with DevOps for production readiness.

Secondary Functions

Support ad‑hoc data requests and exploratory analysis of gameplay telemetry, performance metrics or user behaviour to inform development priorities.
Contribute to the organisation’s interactive media roadmap by aligning Unity‑capability building with business objectives, technology strategy and product vision.
Collaborate with business units, marketing and external stakeholders to translate creative requirements into engineering deliverables, asset workflows and interactive features.
Participate in training sessions, internal workshops and knowledge‑sharing forums to raise team competency in Unity development, AR/VR, optimization and new workflows.
