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. Overview We’re seeking a Senior Mechatronics Engineer - Application R&D to join our NYC-based team and help lead the development of our robot and the tools it uses in real customer warehouses. 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. What You’ll Do: • Design and deploy robot tooling and end effectors that expand our capabilities and solve real customer problems. • Work closely with our team of robot pilots to optimize robot performance for these capabilities- our customers are asking us to develop new capabilities every day, and they have performance metrics we need to be able to hit. • Lead rapid design loops to ship improvements fast — prototype, validate on the robots in the lab, learn, and refine. • Make build-vs-buy decisions for tools and peripherals, selecting off-the-shelf components when smart and developing custom parts when it creates strategic advantage. • Work hands-on with the broader engineering team to make your work compatible with our autonomy stack and ready to scale with our robot platform. Who You Are • You are a mechatronics Swiss army knife, capable of working on every part of the hardware stack for our robotic systems, and have multiple years of experience working in robotics. • You have a portfolio of designing ingenious devices using a wide variety of mechanical and electrical approaches. • You enjoy problem solving, almost to a fault. • You thrive in a high-trust, high-autonomy environment. You don’t need to be micromanaged because you are used to working backwards from customer needs and focusing on the most valuable work. • You are hungry for impact and personal growth. Your dream job is an opportunity to work hard with a team of like-minded engineers building the future of robotics. Experience and Skills • The full mechatronics stack: • 3D design, rapid prototyping, and design for manufacturing • Mechanical and electrical assembly - from machine tools, to soldering, to debugging electrical • Sourcing and testing components such as motors, cameras, and raw materials • Tying designs together with code • Communication: good with customers and vendors alike. You know how to build relationships across the board and maintain them while helping us achieve our goals. • Great at digging deep on a problem, pulling all of your knowledge and connections together to help us build the most performant robots we can • Comfortable with travel to customer and supplier sites Expected Compensation $150,000 - $225,000/annual salary + equity + benefits
