hirify.global develops commercially deployed humanoid robots for warehouses, manufacturing facilities, and distribution centers.

What you will do

• Own end-to-end dynamic simulation analysis for early humanoid robot architecture and product definition.
• Create high-fidelity simulation tools, system models, and digital-twin scenarios for new features and robots.
• Lead architecture reviews and trade studies balancing performance, functional safety, complexity, manufacturability, cost, and reliability.
• Provide technical direction to architects and multidisciplinary engineering teams across software, controls, mechanical, electrical, perception, safety, and systems engineering.
• Translate simulation and performance analysis into testable, traceable requirements for test and integration teams.
• Influence product roadmaps by using user needs, field performance, and research findings to guide architectural evolution.

Requirements

• 8+ years of experience using dynamic simulation to drive product development as a senior or lead engineer.
• 5+ years of experience developing simulation systems, processes, and tools, plus 3+ years of robot system or architecture development.
• Deep understanding of robotic system design, component simulation, digital twins, and OS-in-the-loop systems.
• Strong foundations in software engineering, robot kinematics, dynamics, controls, and system modeling.
• Experience with MuJoCo, Gazebo, or equivalent simulation tools and with integrating simulation into design and validation workflows.
• Proven delivery of complex robotic systems from ideation through production, with strong cross-functional communication and decision-making skills.

Nice to have

• Experience architecting humanoid, legged mobility, mobile manipulation, or high-DOF automation platforms.
• Hands-on experience with perception pipelines, real-time control systems, and safety-rated architectures.
• Experience applying AI and reinforcement learning to robotic learning and control.
• Experience with GitHub, a graduate degree in a related field, or mentoring engineers.

Culture & Benefits
