About You: 

You are interested in the intersection of technology and medicine and the evolving world of wearable sensors and digital health. As a versatile and well-rounded engineer, you can just as easily collaborate with a cross-functional team to meet project milestones as roll up your sleeves for hands-on prototyping in the lab. You are a critical thinker who enjoys working on complex problems and feels comfortable exercising independent judgment. You are detail-oriented, able to juggle competing priorities, and interested in the challenges surrounding medical device production.
