A growing digital team is looking for a Senior Unity-WebGL Engineer to take a leading role in the development of a new platform designed for business use. The platform allows users to create and publish interactive experiences, and this role will play a key part in shaping its functionality, performance, and long-term direction.
 
Key Responsibilities

• Take ownership of the WebGL component of the platform, from architecture through to implementation.
• Integrate Unity-based features into a WebGL environment, with a focus on performance and stability across devices.
• Collaborate with backend engineers to build and maintain scalable cloud services (preferably using AWS).
• Develop internal tooling to support content publishing, infrastructure monitoring, and platform reliability.
• Work alongside Unity designers, frontend engineers (React), and product stakeholders to deliver accessible user-facing features.
• Contribute to sprint planning, mentor junior developers, and provide input into technical direction.
• Investigate and resolve performance issues, especially in high-traffic deployments.
• Drive improvements in codebase quality, reliability, and maintainability.

 
Candidate Profile
 
Essential Requirements:

• Minimum 5 years’ experience in full stack development with a strong command of JavaScript and a working knowledge of Unity/C#.
• At least 3 years’ experience delivering production-ready WebGL applications (e.g. Three.js, Babylon.js).
• Experience contributing to platform or product development rather than project-based or one-off builds.
• Proficiency with cloud infrastructure, preferably AWS, including monitoring and alerting best practices.
• Strong understanding of frontend development (ideally React), with a focus on enabling non-technical users.
• Comfortable in fast-paced environments where priorities shift and decisions must be made quickly.
• Strong communication skills and the ability to work independently as part of a remote team.

 
Desirable Experience:

• Experience working Unity productions / platforms.
• Familiarity with XR SDKs such as ARKit, ARCore, or Vuforia.
• Understanding of network communication and server setup.
• Experience mentoring developers or contributing to technical strategy.
