Principal Robotics Machine Learning Engineer

We operate at the cutting edge of Applied AI, applying our expertise across the full robotics stack to solve some of society's most important problems. You will join a team dedicated to bringing Apollo to market at scale, tackling the complex challenges like safety, commercialization, and mass production to change the world for the better.

The Principal Manipulation Engineer is a core contributor to our robot’s ability to interact with the world with human-like world model context, dynamic perception, and interactive behavior. This role is responsible for the end-to-end lifecycle of learned manipulation, from data engine design through training to on-robot deployment and is expected to diagnose performance bottlenecks. This requires deep fluency in both classical computer vision and modern deep learning to unlock the full potential of state-of-the-art humanoid robot hardware.

This role will bridge the gap between cutting-edge research and scalable, reliable production software. We move at startup pace; intense and focused, but sustainable. We operate with high ownership, fast feedback, and low bureaucracy.

Responsibilities

• Implement and deploy state-of-the-art ML models/algorithms to achieve ambitious, world-class performance on open world object manipulation tasks with physical hardware.
• Drive the data engine for manipulation learning: data collection strategy, curation, annotation, and synthetic/real data mix, in close partnership with data infrastructure teams.
• Drive the entire development cycle, from prototyping in simulation to robustly transferring and fine-tuning models on the robot.
• Identify and prioritize performance bottlenecks, distinguishing between root causes traceable to classical vision (calibration, geometry, sensor fusion) vs those rooted in sub-optimal model/data, to prioritize fixes according to customer-expected levels of reliability.
• Act as a force multiplier across the organization. Beyond code reviews, foster a culture of technical rigor, setting the bar for architectural excellence and mentoring the next generation of robotics leaders.

Expertise in models including CNNs, transformers

• Experience with the initial calibration and tuning of high-DOF robotic manipulators.
• Familiarity with distributed training and MLOps principles.
• Experience with VR/haptic interfaces and retargeting algorithms for human-in-the-loop control.

Requirements

Technical Skills (Must-Have)

• 5+ years shipping machine learning models on robotic systems in production environments.
• Proficiency in Python, C++, and PyTorch, with experience building real-time robotic software stacks.
• Experience with data collection, annotation, and synthetic data generation for ML.
• BS/MS/PhD in Robotics, Computer Science, Electrical Engineering, or a related field.
• 7+ years of relevant experience (or 5+ years with a PhD) specifically focused on robotic manipulation or complex motion control.
• A proven track record of taking complex algorithms from conception to successfully deploying them on physical hardware.
• Prolonged periods of sitting at a desk and working on a computer

Preferred

• Familiarity with 6D pose estimation, camera calibration/extrinsics, point cloud processing and visual-servoing.
• Experience with physics engines such as IsaacSim, MuJoCo, or Drake for policy training and validation.
• Experience using manipulators to automate dynamic real-world material handling tasks.

• Must be able to lift 15 pounds at times
• Vision to read printed materials and a computer screen
