Our culture
We’re a fun, friendly bunch. The office can be quiet one minute and all hands to the pumps the next — when a large delivery arrives, everyone mucks in. You might even find yourself being chased around by someone from the biology team waving a nasal swab. It’s varied, collaborative, and never dull.
