Company

hirify.global is building autonomous science platforms and "Scientific Superintelligence" to accelerate discovery across medicine, materials, and energy.

What you will do

• Design and maintain modular, reusable simulation scene libraries using Universal Scene Description (USD).
• Build Python-based tooling and automation around the Omniverse Kit API for programmatic scene construction and headless Isaac Sim workflows.
• Develop internal simulation SDKs, APIs, and developer tools to enable scalable simulation platform growth.
• Prototype and evaluate physics calibration, sensor modeling, and GPU-accelerated motion planning using cuRobo.
• Implement domain randomization strategies with NVIDIA Replicator and benchmark sim-to-real performance.
• Collaborate with ML and robotics teams to characterize and reduce the sim-to-real gap through physics parameter tuning.

Requirements

• Must be based in or able to work at the facility in Cambridge, MA, USA
• 3–5 years of hands-on experience in simulation engineering, robotics software, or a related field.
• Proficiency with NVIDIA Isaac Sim and the Omniverse Kit framework, including Python scripting via Omniverse API.
• Solid understanding of USD, including authoring modular scenes with references, payloads, and composition arcs.
• Familiarity with robot kinematics (FK/IK, motion planning) and joint control implemented programmatically.
• Strong Python skills for writing clean, maintainable, production-quality code.

Nice to have

• Experience with headless Isaac Sim for automated workflows and cloud-based simulation workloads.
• Knowledge of cuRobo, MoveIt2, or OMPL for trajectory optimization and motion planning.
• Familiarity with NVIDIA Replicator, OmniGraph, and Isaac Lab for RL-based training.
• Experience with ROS/ROS2 and sensor simulation (cameras, depth, LiDAR).
• C++ experience for performance-critical simulation extensions.

Culture & Benefits

• Competitive base compensation with bonus potential and generous early-stage equity.
• Comprehensive U.S. and International benefits packages.
• High-impact environment operating with startup speed to solve problems of historic importance.
• Culture guided by core values of truth, trust, curiosity, grit, and velocity.
