Careers

We are building a small team with concentrated talent, focused on high performance and fast shipping. We look for people with a scientific mindset and high agency: curious enough to dive into complex technical rabbit holes, and pragmatic enough to abstract them into products.

About Mafer

At Mafer we are building an AI data platform for R&D teams in formulation industries: flavors & fragrances, food & beverage, cosmetics, personal care, home care and specialty chemicals. We structure the molecular and formulation data that today lives across instruments, spreadsheets and lab notebooks, and turn it into systems that accelerate analysis, formulation and regulatory work.

We are a small, highly technical team of engineers and scientists, working from our office in Barcelona and backed by tier-1 investors. Everyone here works close to customers: you are either building or selling.

Nothing here fits but you think you should be on this team? Write to info@mafer.ai and tell us what you'd build.
