And you will share your work and knowledge with our users through presentations and technical writing.

What you’ll be doing

  • Developing features, workflows or tools as needed for creators to author Physics in Unity
  • Programming the core constraint solvers in Unity Physics
  • Integrating Physics solvers with Unity
  • Optimizing the performance of Unity Physics

What we’re looking for

  • Experience with Havok, PhysX, Bullet or some equivalent
  • A good understanding of rigid-body dynamics, constraint solvers, and collision detection algorithms
  • Prior experience with Unity
  • Released game titles

You might also have

  • Experience working with DOTS or other ECS systems
