Scientist, Research Scientist, Clinical Research

Cell Signaling Technology (CST) is a different kind of life sciences company, one founded, owned, and run by active research scientists, with the highest standards of product and service quality, technological innovation, and scientific rigor for over 20 years. We consistently provide fellow scientists around the globe with best-in-class products and services to fuel their quests for discovery.

Helping researchers find new solutions is our main mission every day, but it's not our only mission. We're also dedicated to helping identify solutions to other problems facing our world. We believe that all businesses must be responsible and work in partnership with local communities, while seeking to minimize their environmental impact. That's why we joined 1% for the Planet as its first life science member, and have committed to achieving net‑zero emissions by 2029.

We are seeking an experienced and passionate scientist to collaborate closely with our dynamic team in developing groundbreaking technologies and validating innovative products. In this role, you will drive the research for integrating CST's antibodies with new and cutting‑edge technologies. Specifically, your expertise will be instrumental in propelling the development of new products using orthogonal assays. This requires critical thinking about experimental design, data analysis, and future directions.

This is an exceptional opportunity for a dedicated scientist to flourish within a supportive and collaborative team. This is an onsite role.

You’ll have the opportunity to contribute to a variety of projects and impact the development lifecycle of new technologies and products.
