R&D Engineer: Miniature Sensing

Endiatx, Inc. · Hayward, California · Full-time, limited duration employment (3–6 months), with potential conversion to a long-term position · Recent master's or PhD graduates · Immediate start

About Endiatx

Endiatx is a medical device company developing microrobotic systems for diagnostic use inside the human body. Our flagship platforms include PillBot™, a propeller-driven endoscopic capsule designed to enable real-time visualization of the stomach, and PillVue™, a passive capsule endoscopy system designed to improve access to gastrointestinal diagnostics.

We are a multidisciplinary team of engineers, clinicians, and operators building a new category of medical diagnostics at the intersection of robotics, imaging, and AI.

Role Summary

We're looking for a recent master's or PhD graduate to join an early-stage R&D program in miniature biomedical sensing, starting immediately. You'll take ideas from first-principles modeling to working benchtop prototypes, own experiments end to end, and present results that shape real design decisions. This is a hands-on research role, not a support position: expect real responsibility, close collaboration with the CEO and engineering leads, and work that could become part of a regulated medical device. The position runs three to six months, with potential conversion to a long-time position.

We welcome candidates whose strength is on the acoustics and sensor-hardware side, the signal-processing and estimation side, or both, and will shape the project around the selected candidate's expertise.

Required Qualifications

• Completed master's or PhD in biomedical, electrical or mechanical engineering, acoustics, physics, robotics, or a related field.
• Hands-on research experience in at least one of: ultrasound transducers or acoustic systems; analog or mixed-signal circuit design; signal processing for sensing; state estimation or sensor fusion for robots.
• Strong lab skills and a record of designing experiments, collecting clean data and drawing defensible conclusions.
• Proficiency in Python or MATLAB for modeling and data analysis.
• Clear technical writing and the judgment to work independently in a small team.
• Authorized to work in the United States (for example on OPT, H-1B, as a permanent resident or as a U.S. citizen) and available to start immediately.

Nice to Have

• High-frequency ultrasound (roughly 10 MHz and above): transducer design or characterization, piezoelectric materials (PZT, lithium niobate, composites) or MEMS transducers (PMUT/CMUT).
• Experience with acoustic simulation tools (k-Wave, Field II, PZFlex, COMSOL) and measurement equipment (pulser-receivers, hydrophones, network analyzers).
• Pulse-echo or Doppler signal processing, ultra-low-power front-end design, or embedded firmware on microcontrollers.
• Kalman filtering, visual or inertial odometry, SLAM, or underwater robot navigation.
• Work with tissue phantoms, ex-vivo tissue or animal studies, or familiarity with medical device standards (IEC 60601, ISO 14971, ISO 10993).
• Publications, patents or open-source work in any of the above.
