Overview

Application

At Nautilus, we have a big and important mission: improve the health of millions by unleashing the potential of the proteome to accelerate drug development and enable a new world of precision and personalized medicine. We are developing a single-molecule protein analysis platform of unprecedented sensitivity, scale, and ease of use that we believe will democratize access to the proteome - one of the most dynamic and valuable sources of biological insight. To accomplish this, we are pursuing deep, hard science with an entrepreneurial mindset and creating a world-class team of builders, innovators, and dreamers across a wide range of disciplines.

We are looking for a skilled and motivated Senior Research Associate to join our affinity reagent discovery team. In this role, you will be a hands-on contributor to discovery campaigns including affinity reagent selection and characterization from library panning through functional validation. You will provide both technical depth and the flexibility in a fast-moving, multi-project environment.
