Senior Robotics Software Engineer

About 1X

We’re an AI and robotics company based in Palo Alto, California, on a mission to build a truly abundant society through general‑purpose robots capable of performing any kind of work autonomously.
We believe that to truly understand the world and grow in intelligence, humanoid robots must live and learn alongside us. That’s why we’re focused on developing friendly home robots designed to integrate seamlessly into everyday life.
We’re looking for curious, driven, and passionate people who want to help shape the future of robotics and AI. If this mission excites you, we’d be thrilled to hear from you and explore how you might contribute to our journey.

Role Overview

As a Senior Robotics Software Engineer on the Real‑Time Software Team, you will work at the intersection of software, hardware, firmware, AI, and production to build the core systems that run on future generations of humanoid robots. You will develop real‑time C++ software, build tools for system identification and calibration, integrate with sensors and hardware, and help ensure the health, reliability, and safety of robots that will eventually be deployed at scale. Your work will play a critical role in advancing 1X from R&D into full‑scale manufacturing and global deployment.

Responsibilities

• Develop production‑grade, real‑time C++ software for robust control systems

• Design efficient algorithms for state estimation

• Create tooling for system identification, precise calibration of actuators, transmissions, and full‑body kinematics

• Integrate hardware components and evaluate sensors for seamless functionality

• Build hardware bring‑up and debugging tools

• Develop software for robot health monitoring, visualization, and logging

• Build and maintain APIs for other software components to command and control the robot

• 3+ years of professional software engineering experience in a relevant robotics field

• Excellence in C++ and strong proficiency in other programming languages

• Experience with Linux deployed in hardware‑oriented products (e.g., IoT devices, robots, drones, automotive)

• Thorough understanding of object‑oriented programming, real‑time programming, linear algebra, data structures, and algorithms

• Experience with product development practices including release mechanisms, continuous integration, and continuous deployment

• Strong Linux system‑level knowledge: kernel tuning, process scheduling, memory management for optimized performance in robotics applications (preferred)

• Solid understanding of rigid body dynamics and numerical optimization techniques, with application to real‑time systems (preferred)

• Experience writing embedded C for interfacing with sensors or actuators and other parts of the embedded stack (preferred)

• Hands‑on with robotics hardware; having built your own robot or tinker with hardware in spare time (preferred)

Benefits & Compensation

• Health, dental, and vision insurance

• 401(k) with company match

• Paid time off and holidays
