Senior Engineer

Volumetrix LLC, Nashville TN

Responsible for the development of medical devices for clinical and home use.

  • Requirements generation through evaluation of regulatory compliance, risk assessment, clinical and user needs. Translation of design inputs into system architecture for software as well as hardware.
  • Design of hardware systems for the analysis of physiological signals, parameters and data. Including the identification and assessment of new sensor modalities that allow for more accurate or novel diagnosis of physiological events.
  • Translation and performance optimization of diagnostic algorithms for the application on embedded systems, including the development of low level drivers for application layer HW access (Bare-metal, FreeRTOS/SafeRTOS and Linux).
  • Evaluation and hardening of systems for electromagnetic compliance and noise immunity.
