People and Operations Associate

Base pay range

We are looking for a People and Operations Associate to own the processes of the People function at Bactobio, shaping the experience of every person who joins, grows, and thrives with us.

Company

Bactobio is a young London-based BioTech company (2020) using AI, genomics, and synthetic biology to culture previously unculturable microbes and screen them for antimicrobials. We regularly discover chemically novel antimicrobials that are effective against some of the biggest infectious diseases in agritech and healthcare, and select diseases to target based on the lack of current, effective solutions and the potential market size.

Our work culture is built around impact, empowerment, and collaboration, and we have managed to attract incredible scientists from world-leading institutions, alongside operational experts. We believe that open and inclusive conversations lead to better solutions. As a result, we have created a unique work environment, where ambitious people enjoy working together to make the world greener and safer.

Team

You’ll be part of the Operations team — a close-knit group that manages Bactobio’s daily business operations with a lean structure and a strong ownership mindset. We thrive on collaboration and mutual support, and are not afraid to ask for help when it can lead to better results, and we’re just as quick to offer a hand when someone else needs it. We work as one team with a shared goal: getting things done together, better.

Role

This role keeps Bactobio’s People engine running smoothly and makes sure every team member has a great experience from their first interview to their last day.

You’ll be the go-to person for all HR-related matters, responsible for evolving our policies, drive engagement initiatives, and build systems that scale as we grow.

This role is perfect for someone who thrives in a high-autonomy, fast-paced environment, loves variety, and enjoys turning ideas into action. You’ll have the space to experiment, innovate, and shape how we care for and empower our people — all while being part of a collaborative and trusting team.
