Job description

Design Engineer – EnTox Sciences

Location: Seattle, WA

Compensation: $80,000 – $90,000 base salary + performance bonus + equity package

About EnTox Sciences

EnTox Sciences is advancing next-generation instrumentation for retinal and diabetic research. Our flagship technology, BaroFuse system, enables precise biochemical and optical assessments of cells and tissues in response to changes in dissolved gases and test compounds. We are a fast-growing, mission-driven company where engineers, scientists, and innovators collaborate to bring impactful tools to life.

Role Overview

We are seeking a Design Engineer with 2–4 years of experience and a bachelor’s degree in electrical engineering, computer science or related fields. This role is hands-on, multidisciplinary, and focuses on the design, fabrication, and integration of EnTox’s instrumentation. You will work across mechanical, electrical, and software domains to build systems that directly support biomedical research.

EnTox Sciences works closely with Dr. Ian Sweet’s laboratory at the University of Washington, where the collaboration is supported by STTR grants from the NIH and NSF. EnTox is positioning itself as a leader in analytical instruments that assess the rapid effects of biomedically important dissolved gases including O2, CO2, and gas signaling molecules H2S, CO and NO on cells and tissue. Recent results have revealed differences between effects of the physiological gas vs. commonly used donor molecules (1) indicating the critical need for specialized equipment to study dissolved gases. In particular, resolving rapid changes in cell function in response to changes in O2 revealed novel mechanisms of acute regulation in response to hypoxia and hyperoxia (2). It is expected that new instrumentation will continue to generate groundbreaking data that will provide EnTox employees opportunities to publish in both engineering and life science journals: https://www.entoxsciences.com/publications.html
