Company

hirify.global builds humanoid robots for home environments, including NEO, a robot designed to move, learn, and operate safely alongside people.

What you will do

• Develop the real-time software stack for humanoid robot motion, balance, manipulation, and reliable operation.
• Design and deploy state estimation systems and control algorithms for balancing, locomotion, and manipulation.
• Build software abstractions and APIs that allow higher-level AI systems to command complex, high-DOF hardware.
• Perform system identification and calibration of actuators, transmissions, and full-body kinematics.
• Develop tools for hardware bring-up, debugging, health monitoring, visualization, and logging.
• Bridge hardware and AI layers while supporting the transition from research and development to large-scale production.

Requirements

• 3+ years of professional experience deploying and debugging control or estimation software on high-DOF robots.
• Strong understanding of rigid body dynamics, linear algebra, numerical optimization, and robotics control.
• Experience implementing optimization-based whole-body control, EKF-based state estimation, or model predictive control for legged systems.
• High proficiency in clean, production-ready C++ in a Linux development environment.
• Experience evaluating and integrating robotics hardware components, including sensors and actuators, and debugging hardware-software systems.
• Strong understanding of version control, testing methodologies, and system architecture.

Nice to have

• Experience with Java, Unity/C#, Python, real-time Linux, ROS2, or DDS.
• Background writing embedded C for sensors or actuators.
• Familiarity with the Yocto OS build system.
• Independent hands-on experience building or modifying robotics hardware from scratch.

Culture & Benefits

• Work on humanoid robots transitioning from research and development to large-scale production.
• Health, dental, and vision insurance.
• 401(k) with company match.
• Paid time off and holidays.
• Competitive equity package.
