- Develop and maintain advanced Unity applications targeting WebGL.
- Design, implement, and iterate on gameplay features and game systems from concept through release.
- Build intuitive, polished, and engaging player experiences with a strong focus on gameplay quality.
- Optimize browser performance, memory usage, loading times, and frame rate.
- Build and maintain real-time multiplayer systems using Photon (PUN), MFPS, or similar networking frameworks.
- Integrate blockchain wallets, smart contracts, and digital asset transactions.
- Develop and maintain backend services using Node.js and TypeScript.
- Implement secure client-server communication and anti-tampering systems.
- Manage remote content delivery using Unity Addressables.

What We're Looking For
We're looking for an experienced engineer who enjoys building great games as much as solving difficult technical challenges. The ideal candidate can take a feature from idea to implementation—designing gameplay systems, writing clean, maintainable code, optimizing performance, and shipping polished experiences. They should be comfortable working across Unity, multiplayer networking, backend services, and Web3 technologies while taking ownership in a fast-moving startup environment.
