About The Position

Aether engineers enzymes to produce materials that are difficult or impossible to make by conventional means, building on billions of years of evolution rather than inventing chemistry from scratch. The long-term goal is to make almost anything manufacturable quickly and affordably, anywhere in the world. Today our print materials ship into defense and unmanned systems, generating revenue and strong customer feedback. In parallel, our machine learning effort is assembling what we believe to be the largest protein-material binding dataset of its kind, working toward a model that can identify which proteins will produce a specified material. Aether is a Series A company with over $60 million raised and a team of ~40 very talented humans. The Role We're looking for a Marketing Communications Manager to own the full breadth of our external-facing presence, from crafting technically rigorous content to organizing our conference presence to building a social following among the engineers, operators, and procurement teams who buy materials. You'll report directly to our Head of Commercial and work closely with our founders, scientists, and engineers to translate complex science into customer-ready stories. You don't have to be an expert in every discipline, but you'll bring genuine depth in a few areas and the drive to learn the rest. You'll have significant latitude to define what great marketing looks like at Aether.
