Job description

AutonomUS is an MIT/MGH spinout building AI-enabled, ultrasound-guided robotic systems that automate life-saving medical interventions currently limited to expert physicians. Our flagship device combines real-time computer vision, robotics, and edge AI into a compact, elegant, handheld platform. We are supported by the NIH and Department of Defense, have earned FDA Breakthrough Device Designation, and collaborate closely with MIT Lincoln Laboratory and leading physicians at the Massachusetts General Hospital.

This is a rare opportunity to join at the ground floor of a high-potential medical robotics company with deep technical foundations and real-world impact.

What You’ll Do

You’ll be a foundational team member, shaping a complex, high-performance medical product. Your work will span concept development, prototyping/test, and transition to production. You’ll also own product and requirements documentation, and collaborate with physician-inventors, roboticists, software engineers and systems engineers to a build first-of-its class device that matters.

To succeed in this role, you’ll need to be adept at:

• The design of exceptionally clever mechanical mechanisms
• Ownership of design-related documentation
• Lead and/or assist with FDA regulatory paperwork
• Mechatronics, structural analysis
• Rapid prototyping utilizing Solidworks and 3D printing
• Transitioning designs to manufacturing
• Work within a fast-moving, deeply collaborative, zero-fluff environment with exceptionally high standards.

What You Bring

• 15+ years of experience in design of medical devices
• Proven experience bringing a complex medical device from concept to product
• Comfort building early-stage, FDA-regulated products where iteration, precision, and a team-first mindset are paramount. You have a track record of delivering results under pressure.
• A personality that balances cordiality, emotional stability, and intellectual sharpness. We work hard, we support each other, and we aim to win.
• Must be a US citizen or Green Card holder. We are unable to provide visa sponsorship for this position.

Our Interview Process

Our interview process is designed to assess your technical depth, problem-solving skills, and approach to real-world engineering challenges. It includes a behavioral interview and deep-dive technical discussion with the team.

Why AutonomUS?

• Build technology that literally saves lives.
• Join a world-class team with ties to MIT, MGH, and the Department of Defense.
• Work on hard problems with high autonomy in a mission-critical environment.
• Share in the company’s future. We are laser-focused on a major exit, and our team will be rewarded accordingly.
• Help redefine how interventional medicine is delivered across the world and improve access to high-quality care in low resource environments.
