Senior Robotics Engineer, Controls

Job description

Senior Robotics Controls Engineer | Software Engineer
Palo Alto, CA (on-site)

About 1X
We build humanoid robots that work alongside people to solve labor shortages and create abundance.

The Role
As a Senior Robotics Controls Engineer, you will develop the real-time software stack that enables our humanoid robots to move, balance, and manipulate the world with precision and reliability. Your work will span low-level motor control through whole-body dynamic control and estimation, making complex, high-DOF hardware accessible through clean and efficient software abstractions. This role is pivotal in bridging hardware and AI layers, and your contributions will be critical as we transition from R&D to large-scale production.

You Will

• Develop control algorithms for balancing, locomotion, and manipulation in humanoid robots

• Design fast and efficient state estimation systems

• Perform system identification and calibration of actuators, transmissions, and full-body kinematics

• Integrate and evaluate hardware components, including sensors and actuators

• Build tools for hardware bring-up, debugging, and robot diagnostics

• Develop software for health monitoring, visualization, and logging

• Build and maintain APIs for higher-level systems to command the robot

Must Have

• 3+ years of experience deploying and debugging control or estimation software on high-DOF robots

• Strong understanding of rigid body dynamics, linear algebra, and numerical optimization

• Experience with optimization-based whole-body control, EKF-based state estimation, or model predictive control for legged systems

• Proficiency in C++ within a Linux development environment

• Familiarity with modern software development practices, source control, and testing

Nice to Have

• Experience with Java, Unity/C#, Python, real-time Linux, ROS2, or DDS

• Background in writing embedded C for sensors or actuators

• Familiarity with the Yocto OS build system

• Hands-on experience building or working with robotics hardware independently

Benefits & Compensation

• Salary Range: $137,861 – $240,000 + Equity

• Health, dental, and vision insurance

• 401(k) with company match

• Paid time off and holidays
