About Ultra

Ultra builds industrial AI robots that are working in the real world today. Our robots automate mission-critical warehouse labor end-to-end, starting with e-commerce order packaging. We deploy fast, learn from real production data, and iterate aggressively. We already have a quickly growing number of revenue-generating robots operating in U.S. warehouses, and are now scaling towards thousands of deployments over the next few years. Our mission is simple: build the world's most useful and deployable robot.

WARNING: Robotics is not for the faint of heart. There are no silver bullets here. It is tiresome, unglamorous, and at times brutal work. The only way out is through, and the only way through is treacherous and unknown. Success will require teamwork - so we are building a world-class team to tackle some of the most exciting problems out there. We hope you join us.

Overview

We’re seeking a Robotics Firmware Engineer to join our NYC-based team (we are an in-person company) to own the hard problems where software meets metal. Our robots run every day in the lab and at customer sites; when joints freeze, buses flake, or safety state is wrong, you are the person who finds the real cause and ships the fix. We are an early stage company moving very fast in a rapidly growing space, and welcome people from any background as long as you’re excited to join our mission, drive immediate impact, and create a future where automation is accessible to all.

Who You Are

• 2+ years shipping firmware on real robots or similarly unforgiving embedded systems
• You’re dangerous with LLMs because you know when they're wrong
• Comfortable from scope traces and schematics up through kernel/driver and into application control loops
• You’ve identified, diagnosed, and fixed intermittent failures end-to-end (timing, noise, thermal, state machines)
