About the role
We're looking for a Controls Systems Engineer to design, implement, and tune the real-time control loops that make our actuators and joints move precisely, safely, and reliably. This is the layer that sits closest to the hardware — motor drive, current and torque control, position/velocity control, and the embedded software that runs it on real silicon, in real time, on a real robot.
What they're looking for
- Bachelor's, Master's, or PhD degree in Mechanical Engineering, Electrical Engineering, or a related field
- 5+ years of experience designing and implementing low-level motor or actuator control systems (less with an advanced degree focused on controls)
- Strong fundamentals in classical controls: PID, cascaded control loops, feedforward, and frequency-domain or state-space analysis
- Experience with time synchronized torque control of motors (BLDC/PMSM, FOC, current/torque control) or other electromechanical actuator force control
- Experience working with encoders, strain gauges, or other analog or digital sensors
- Hands-on embedded firmware experience in C or C++ on microcontrollers or DSPs, including real-time constraints and interrupt-driven code

Persona AI is building humanoid robots for the most demanding environments in heavy industry — shipyards, steel mills, fabrication facilities, and offshore platforms — performing welding, grinding, maintenance, inspection, and material-handling work that is dangerous, physically demanding, and increasingly difficult to staff.
We are backed by leading strategic and financial investors and engaged with global industrial leaders across Korea, Japan, the United States, and Singapore. Korea is the center of gravity for our early commercial strategy, anchored by relationships with the world’s leading shipbuilders and steelmakers. Our work spans both the robot platform itself and the systems, partners, and playbooks required to deploy it at scale.
We offer competitive compensation, a performance-based bonus, 99% employer covered medical benefits, early-stage equity, competitive PTO, and a company-wide paid winter break between December 24th and January 2nd.
You’ll shape technology that’s redefining the possibilities of robotics and human interaction.
Work alongside passionate teammates who value creativity, and continuous learning.
