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.

About the Role

Join Ultra's elite, Brooklyn-based Manufacturing team and help us scale from prototypes to production—we're already building 10+ AI-native industrial robots every month, with aggressive growth planned for the months and years ahead.
You'll work directly with our engineering and production teams at our Brooklyn headquarters, taking ownership of the complete manufacturing process for our fleet of warehouse automation robots. This role is critical: customer demand for our robots is high and increasing, and you'll help to establish and maintain our production quality standards and processes as we scale from dozens to thousands of deployed systems.

What You'll Do

Core Responsibilities

• Build complete robot systems from fabricated parts, PCBs, motors, sensors, and compute modules
• Fabricate and integrate custom wiring harnesses, including soldering, crimping, and professional cable management
• Ensure assembly quality standards: proper strain relief, correct torque specifications, clean wire routing, and reliable connections
• Perform functional testing and verification of assembled systems before deployment
• Document assembly issues and recommend process improvements as we iterate on designs
• Support occasional deployment, troubleshooting, and field service as needed

What We're Looking For

Required

• High school diploma or equivalent
• 2+ years of hands-on assembly experience in electromechanical systems (automotive, industrial equipment, robotics, or similar)
• Demonstrated proficiency with soldering and cable fabrication
• Strong attention to detail and quality control mindset—you take pride in work that's built to last
• Comfortable with hand tools, power tools, and assembly fixtures
• Manual dexterity for both precision work and general assembly
• Ability to regularly lift 50+ pounds
• Basic computer skills (email, documentation, internet)

Preferred

• Technical degree or certification (automotive technology, electronics, mechatronics, etc.)
• Experience with root-cause analysis and troubleshooting in engineering production environments
• Background in quality control or process improvement initiatives
• Strong interest in tinkering and making cool things
• Familiarity with torque specifications, fastener types, and mechanical best practices

Expected Compensation$55,000 - $90,000/annual salary + equity + benefits
