Simulation Engineer (AI)

Location: Redwood City, CA (Hybrid)

Company

hirify.global is building unified general intelligence capable of generating, understanding, and operating in the physical world through multimodal vision-based models.

What you will do

• Design simulation environments that blend generative rollouts with physics-engine scenes.
• Build evaluation harnesses to measure sim-to-real gaps, physical consistency, and long-horizon coherence.
• Develop differentiable and GPU-accelerated simulation pipelines to unlock new training signals.
• Drive asset, scene, and task generation pipelines using hirify.global's generative stack.
• Collaborate with world-model and policy-learning research teams.

Requirements

• Strong background in robotics simulation, computer graphics, physics-based modeling, or generative 3D.
• Fluency in Python and C++.
• Deep familiarity with at least one production physics engine such as Isaac Sim/Lab, MuJoCo, Bullet, PhysX, or Drake.
• Proven track record of building simulation systems used by others.
• Ability to work on-site in Redwood City, CA.

Nice to have

• Research experience in sim-to-real transfer, domain randomization, or neural-rendering-based simulation.
• Background in game engines, CGI, animation, or photogrammetry.
• Publications at top venues like CoRL, RSS, ICRA, NeurIPS, or SIGGRAPH.

Culture & Benefits

• Opportunity to work at the intersection of generative AI and robotics.
• Collaborative research-driven environment.
• Focus on building scalable, high-impact simulation infrastructure.
