Hardware Lead

At Mosaic Intelligence Labs we're building machine intelligence to enable the next generation of surgery: endovascular.

Our mission is to make surgery safer, more precise, and more accessible by combining multimodal sensing, robotics, and machine learning into systems that can perceive, navigate, and ultimately operate safely within the human vasculature. We believe the future of surgery will be incisionless, perception-first, and increasingly autonomous.

Our founders began this journey in operating rooms at Stanford, learning directly from physicians and their teams. But they were deeply dissatisfied with the status quo in medtech, and found the needs-driven approach to product development to be a necessary but not sufficient feature of building a great company. After spending several years away from the medtech industry, we pride ourselves on being highly intentional about what we keep and what we shed of medtech’s traditional ways.

We're looking for our Hardware Lead to help us scale this approach.

About the Role

We need a hands-on hardware engineer to design, build, and test the robotic systems at the heart of our platform. The mechanical design of the system is yours, from early concepts to a product ready for clinical use. You'll define the system architecture with our founders and engineering leaders, incorporating input from the software, controls, and clinical teams.

A typical week might include defining how the robot's major subsystems fit together, building a quick prototype to test a design hypothesis, and reviewing a junior engineer's design before it goes out for machining.

Success means robotic hardware that performs reliably in the operating room, built by engineers who grew alongside you.

You'll report to our VP of Engineering as a technical lead and build the hardware organization. The right person loves to build, can take a capital robotic system from napkin sketch to product, and finds real joy in helping more junior engineers develop their judgment and craft.

What You'll Build

• Robotic systems:

  • Hands-on design: Design, prototype, and test the robot's mechanical and mechatronic subsystems, personally owning the most critical designs.

  • System architecture: Define a hardware architecture that can grow with the product, working with the robotic controls team on integration.

  • Failure analysis: Take failures from the bench and preclinical studies through root cause to verified fix.

• Engineering leadership:

  • Mentorship: Coach junior engineers through design reviews and hands-on work at the bench.

  • Design process: Choose our CAD and PLM tools and set practices for drawings, tolerance analysis, design reviews, and build documentation.

  • Team, consultants, and suppliers: Grow the hardware team, manage external consultants, and build relationships with machine shops, vendors, and contract manufacturers.

• Operating room readiness:

  • Sterility and clinical workflow: Design the system to stay sterile, set up and tear down cleanly, and hold up to cleaning and daily use in a cath lab or OR.

  • Safety and compliance: Contribute to design controls (ISO 13485), risk management (ISO 14971), and IEC 60601 electrical safety and EMC testing.

  • Design for manufacture: Take designs toward production with an eye on reliability, serviceability, and cost.

What We're Looking For

• Strong engineering foundations: A background in mechanical engineering, mechatronics, robotics, or a related field, with hands-on experience building and debugging electromechanical systems.

• Relevant experience: 8+ years of hardware product development, including time as a hands-on technical lead.

• Capital robotic systems: You've taken a capital robotic or electromechanical system to a verified product ready for production.

• Mechatronics depth: Mechanism design, actuators, transmissions, motors and encoders, tolerance analysis, materials selection, and strong CAD skills.

• Joy in mentoring: You measure your success partly by how much more your team can own over time.

• Collaborative maker: You'd rather fix a problem than describe it, the best idea wins whoever it came from, and you earn trust across disciplines.

• Energized by early stage: You thrive when the product, the process, and your own role are still taking shape.

Ways to Stand Out

• Surgical robotics: Developing capital surgical robots used in the OR or cath lab.

• Sterility and clinical deployment: Designing systems that stay sterile and functional in the OR, and supporting them in real procedures.

• Medical device development: Design controls, risk management, verification and validation, IEC 60601 testing, and submissions, with an eye for leaner ways to meet their intent.

• Endovascular experience: Familiarity with catheter-based procedures and devices.

• Scaling to production: Design for manufacture and assembly, supplier management, and transfer to contract manufacturing.

• Disposable experience: Enough familiarity with disposable device design to direct specialists.

If you match some of this but not all, we'd still like to hear from you.

About Our Team

We're a small, technically deep team building a new category of intelligent surgical systems. Our work brings together robotics, medical imaging, mechanical engineering, machine learning, and clinical medicine. We believe in testing on physical systems early, learning directly from clinical collaborators, and iterating quickly.

In this role you'll define how hardware gets built at Mosaic as well as what we build, working side by side with our founders, physicians, and engineers from your first week.
