Senior Front-end Engineer – Byteflies

Senior Front-end Engineer (SF)


We are a young and exciting Belgian-American wearable health startup with offices in Antwerp, Belgium and Silicon Valley, California. Our goals? To become a global wearable health leader, make the Byteflies brand eponymous with medical wearables, and be at the forefront of healthcare and clinical trial innovation. Founded in April 2015, we grew to a multidisciplinary team of experts in sensor design, pathophysiology, embedded software, cloud architecture, app design, and medical signal processing. Our first product, Sensor Dot, has officially launched, so the time to join is now!

You are an experienced front-end developer obsessed with every detail and methodical in hunting down and combating the slightest jank in the applications that you create. You take each UI hiccup as a personal affront to your honor and will not rest until every screen and pixel is delivered at 60 frames/second of buttery smoothness. You enjoy working in a high-paced multidisciplinary environment with huge potential for growth and understand that with great power comes great responsibility.
