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 multiple revenue-generating robots operating in U.S. warehouses, and are now scaling toward hundreds of deployments over the next couple years. Our goal is simple: build the most advanced, most productive industrial AI robots on the planet.
We’re seeking a Senior Mechatronics Engineer - Robot Platform to join our NYC-based team and help evolve our robot platform from high-performing prototypes into scalable, resilient products ready for manufacturing and deployment at scale.
This role sits at the intersection of R&D, operations, and supply chain. You’ll take feedback from our deployed systems as well as new R&D concepts and drive them toward manufacturable, resilient, and supportable systems — making the right tradeoffs between performance, reliability, cost, and scalability.
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 help create a future where automation is accessible to all.
What You’ll Do
- Own a significant portion of our robot's hardware platform - you are responsible for mechanical and electrical design and component selection.
- Work with operations and deployment teams to identify recurring field issues and solve them with engineering improvements
- Help transition advanced R&D prototypes that expand our capabilities into platform designs we can deploy at scale
- Help define platform standards, common interfaces, and reusable modules that simplify assembly while improving resilience and serviceability
- Collaborate with the larger team to select reliable hardware partners, improve component quality, and reduce supply chain risk.
Who You Are
- You have seen a hardware platform transition from early stages to scale, and understand all of the pieces that are necessary to make that scale possible.
- You naturally consider reliability, maintainability, and operational realities when making design decisions.
- You’re comfortable moving between mechanical, electrical, and systems-level thinking.
- You thrive in high-trust, high-autonomy environments and work backwards from real-world needs.
- You enjoy turning messy, early-stage designs into clean, robust, repeatable systems.
- You are hungry for impact and personal growth, and want to help build the future of robotics with a small, highly capable team.
Experience and Skills
- Full-stack mechatronics experience
- 3D design, rapid prototyping, and design for manufacturing/assembly
- Mechanical and electrical assembly, debugging, hands-on fabrication
- Experience improving reliability and simplifying designs for production
- Strong intuition for failure modes and operational resilience
- Platform & manufacturing
- Experience shipping hardware into real-world environments
- Working with CM/ODM partners or production suppliers
- Understanding of mechanical tolerances, electrical wiring and strain relief, QC processes, and scaling challenges
- Sourcing motors, sensors, cameras, and custom components
- Communication & collaboration
- Strong communication skills with vendors, customers, and internal teams
- Excellent research and problem-solving ability — able to quickly evaluate tradeoffs across vendors and technologies and know when to go deep on a problem
- Willingness to travel to customer and supplier sites within the US and internationally to build strong relationships across the board (including China, Mexico, and the EU)
