Principal AI Research Engineer - World Models - Reflex Robotics : Job Details

Reflex Robotics Job Post

Reflex Robotics is building affordable ($10k) wheeled humanoid robots to automate dangerous and repetitive tasks in manufacturing and logistics.

We envision a future where intelligent robots handle all kinds of boring work that people dislike, such as loading chicken nuggets into Costco boxes, lifting forty-pound bags of dog food at Petco stores, and cleaning up cranberry juice spills in your apartment.

We are a three-year-old startup backed by Khosla Ventures, with $60M/year of revenue lined up pending successful pilots with e-commerce warehouses in 2025.

Our robots are designed and built entirely in-house by an engineering team that led development of the Stretch robot at Boston Dynamics and key systems on the Tesla Model S, X, and Y production lines. Reflex robots are high-performance, low-inertia, and optimized for low-cost manufacturing.

We've built the best real-time teleoperation system in the world, allowing a remote operator in South America to play a video game to control our robots at human-level speeds. This has already enabled us to ship robots with positive unit economics and creates a powerful human-intervention + RL product feedback loop.

Our system allows us to collect high-quality demonstrations at scale, giving us the proprietary data engine needed to train increasingly capable AI systems. We're on track to build the largest robotics dataset in the world, which will be a significant long-term advantage.

Key Company Beliefs

• High-quality, proprietary robotics data is the next foundation for generational AI companies (like Tesla FSD and ChatGPT).
• Solving our customers' biggest pain points is more important than merely maximizing engineering metrics.
• An intense work ethic is required for outsized success—and you'll be rewarded for it.

What We're Looking For

We're still a small team, which means high ownership, high equity, and the chance to shape the product from the ground up.

While VLAs and other base policies for robotics achieve ~80% success rates, real robot deployments require 99.99% success rates. We can't ask our customers to tolerate errors like packing three socks instead of four or swapping shipping labels even once! You should apply if:

• You've architected and trained large-scale video/world models (e.g., Sora, Veo).
• You've turned generative models into controllable simulators: action? / state? conditioned rollouts.
• You've built the data & evaluation stack for world modeling to quantify downstream policy success.

You'd be joining a company that already has a solid core business with working hardware, delighted customers, and profitable unit economics. Reflex is de-risked enough to see the outlines of success but still small enough for enormous upside.

This is a rare opportunity to help build a flagship robotics company from the ground up and do work that will truly matter, reshaping perceptions of what is possible in robotics.

We love to see your work—portfolio, projects, or insane accomplishments. Share it. We're looking for people who push past the status quo, are passionate about their work and personal projects, and want to win.
