Full Job Description
You will contribute to a pivotal stage of the company, where the work you do will help shape the technology, the product, and ultimately the experience of patients and healthcare providers around the world.

Why This Role Matters:

This is not just another engineering job-it is an opportunity to shape the future of healthcare. We are gearing up to take our groundbreaking ultrasound prototypes from the lab to the hands of real-world users.

You will play a key role in the fabrication, assembly, characterization, and continuous improvement of the transducers that power our technology. By helping us better understand, measure, and control device performance, you will contribute directly to the reliability of our products, the quality of our data, and the future evolution of our designs. This is a highly impactful, hands-on role for an engineer who enjoys solving practical problems, working closely with hardware, and bringing structure and rigor to complex technical processes.

What You Will Do:
  • Support the fabrication, assembly, and characterization of polyCMUT ultrasound transducers
  • Perform electrical and acoustic measurements to evaluate device performance
  • Analyze test results and generate documentation, reports, and records to support traceability and future design improvements
  • Contribute to the development, standardization, and continuous improvement of fabrication, assembly, and characterization processes
  • Maintain organized datasets, measurements, and technical documentation to support quality control and reproducibility
  • Collaborate with engineers and researchers across fabrication, MEMS design, systems engineering, and ultrasound development

What You Will Bring:
  • Experience using electrical characterization tools such as impedance analyzers, vector network analyzers (VNA), or similar equipment
  • Experience in handling and maintaining measurement databases for traceability
  • Experience with prototyping and hands-on engineering work (power tools, CNC, 3D printing, CAD design, basic PCB design)
  • Basic programming experience using MATLAB, C++, or similar languages
  • Strong analytical, organizational, and documentation skills
  • Ability to collaborate and communicate effectively within a multidisciplinary engineering tea

What Will Set You Apart:
  • Experience with ultrasound technologies, signal processing, or medical devices
  • The ability to translate electrical and acoustic measurement data into actionable engineering insights
  • Hands-on experience conducting microfabrication processes in a cleanroom environment (Lithography, PVD, surface characterization, etc)
  • Experience in mechanical design and automation of processes
  • Experience developing characterization, testing, or traceability workflows
  • Familiarity with modern AI tools and the ability to leverage them effectively to improve engineering productivity, problem-solving, and decision-making

What's In It For You:

You're joining at a crucial moment in the company's history: before scale, when the decisions you make stick and have lasting impact on the product, the team, and the company we become.
  • Frontier Technology: Work on a platform with no direct commercial equivalent, alongside the researchers who invented it
  • Flexibility: High trust, real autonomy, and the flexibility to do your best work
  • Equity: Meaningful stock options in an early-stage company with institutional backing
  • Agency & Impact: Your decisions and innovations will shape the product, not just inform it


We Encourage Diverse Perspectives

We believe that varied backgrounds, experiences, and perspectives help us solve complex problems, and recognize that expertise and potential are not always captured by a job description, so if you can help drive our mission forward, we encourage you to apply!
