Robotics Engineer

About The Role

A seed-stage, Y Combinator–backed humanoid robotics software company is looking for a Robotics Engineer to join a tight-knit, three-person engineering team in San Francisco. This company builds the "social brain" for humanoid robots — software that enables natural, intelligent human-robot interaction, including perception, emotional awareness, on-device decision-making, and autonomous locomotion.

You'll work hands-on with cutting-edge humanoid hardware, develop real-world autonomy software, and advise robot manufacturers on sensor placement and hardware design. This is a high-ownership, high-impact role where your work ships directly to customers.

What You'll Do

• Develop autonomy software for humanoid robots deployed in real-world, customer-facing environments.
• Advise robot manufacturers on sensor placement, hardware interfaces, and operational design for next-generation humanoids.
• Work hands-on with premium humanoid hardware (robots that cost more than most cars).
• Implement and improve camera-based 3D perception, including object detection, tracking, gesture recognition, body language understanding, and speaker identification.
• Improve locomotion systems for safe walking in public environments.
• Collaborate with animators to make robot movement, body language, and gestures more fluid and natural.
• Deploy and maintain onboard C++20 and offboard Python 3.14 code on humanoid platforms upfit with custom hardware.
• Iterate rapidly on software deployed to customer robots in live, real-world settings.
