Your work will span gameplay systems, UI, performance optimization, networking, automation, and platform-specific challenges.
You’ll also help shape engineering standards and explore new AI-powered workflows that make development faster without compromising quality.
This is an ideal environment for a creative, technically strong developer who enjoys ownership, experimentation, and building games at scale.
Accountabilities
- Develop and maintain high-quality mobile games in Unity for iOS and Android platforms.
- Build gameplay systems, UI, animations, VFX, audio features, and live-operations functionality using clean and scalable C# code.
- Use AI-powered development tools to accelerate coding, debugging, testing, refactoring, documentation, and rapid prototyping while maintaining production-quality standards.
- Critically review and validate AI-generated code before integrating it into production systems.
- Collaborate with designers, producers, artists, backend engineers, and QA to deliver polished and engaging player experiences.
- Prototype gameplay mechanics quickly, gather feedback, and iterate on features throughout development.
- Optimize CPU, GPU, memory, battery usage, and overall performance across a broad range of mobile devices using Unity profiling tools.
- Diagnose and resolve complex gameplay, networking, memory, and platform-specific issues.
- Implement and maintain integrations involving REST APIs, WebSockets, and multiplayer networking.
- Contribute to CI/CD processes, build automation, deployment pipelines, reusable systems, and internal development tools.
- Participate in code reviews and help establish strong engineering standards and development practices.
- Evaluate emerging AI tools and workflows that can improve development velocity while considering quality, security, and technical limitations.
- Participate actively in Agile ceremonies, including sprint planning, daily standups, and iterative development cycles.
