🛠 Tech Stack

💼 About This Role

You'll join the team that brought Unity to visionOS, inventing how different real-time 3D runtimes communicate and render. You'll implement systems that let Unity run reliably inside other processes, engines, and environments, owning features like input, physics, and animation. This is your chance to build fundamental infrastructure for the next generation of interconnected game ecosystems.

🎯 What You'll Do

  • Implement and extend subsystems across the game engine stack in C++ and C#.
  • Profile and optimize execution timing and resource contention between processes.
  • Improve loading, serializing, and synchronizing components in bandwidth-constrained environments.
  • Refactor engine code into decoupled modules for embedded and shared execution.

📋 Requirements

  • Game engine experience: developed or heavily modified core or foundation systems.
  • High-performance coding: solid C++ and C# with cache-friendly data layout knowledge.
  • Versatility: willing to dive into unfamiliar areas like physics or serialization.
  • System depth: experience in at least one engine area (physics, animation, input, etc.).

✨ Nice to Have

  • Experience with WASM, embedded runtimes, or compiler pipelines (Mono, CoreCLR).
  • Understanding of multithreading, job systems, lock-free data structures, or Unity DOTS.
  • Experience solving cross-platform issues across consoles, mobile, and desktop.

  • 🏖️ Generous PTO: vacation and personal days
  • 💰 Employee stock ownership program
  • 🏥 Comprehensive health, life, and disability insurance
  • 👶 Support for new parents: leave and family-care programs
  • 📚 Training and development programs
