Senior Machine Learning Engineer

$136.1k - $204.1k per year

Unity Enterprise

What you’ll be doing

  • Design, implement, and scale AI agent systems in Unity environments that enable goal-directed behaviour, task planning and execution, and environment-aware decision‑making.
  • Develop reusable agentic frameworks - such as planning modules, memory systems or policy adaptation layers - that creators can extend in their own projects.
  • Develop AI models for the Unity AI agentic system. The AI models perform various tasks for building Unity games.
  • Integrate Machine Learning models seamlessly within real‑time game engine constraints, optimising for latency, compute, and determinism.
  • Lead high‑impact initiatives, including hierarchical reinforcement learning for scalable behaviours, AI planning and goal inference frameworks for NPCs and simulations, and agent memory and world modelling systems for persistent, believable behaviour.
  • Collaborate across internal and external teams to unlock innovative use cases in gaming, simulation, and interactive storytelling.
  • Contribute to the long‑term vision and roadmap for Unity’s agentic AI offerings, ensuring modularity, usability, and performance across platforms.
  • Establish and champion best practices for model quality, simulation‑based evaluation, and ML/AI safety within real‑time systems.
  • Mentor engineers and researchers while cultivating a technical culture of innovation, excellence, and collaboration.

What we’re looking for

  • Advanced degree (MS or Ph.D.) in Computer Science, Machine Learning, Robotics, or a related field—or equivalent practical experience.
  • 5+ years of hands‑on experience developing ML systems in production, ideally within real‑time or interactive environments.
  • Strong background in one or more of the following: reinforcement learning, fine‑tuning, decision‑making under uncertainty, AI planning, or multi‑agent systems.

En plus du salaire de base, ce poste peut donner droit à des attributions d’actions et à une participation à nos programmes d’incitation de l’entreprise, comme des primes annuelles discrétionnaires ou des commissions de vente.
