Antiverse

Cardiff, sbarc|spark | Full-time | Leadership Team

Build the people function for a scaling AI biotech company!

Antiverse is an AI-driven biotech company designing antibodies against some of the most challenging targets in medicine, including GPCRs and ion channels. Headquartered in Cardiff, with a growing presence in Boston, we combine machine learning, advanced cell-line engineering and experimental biology to create new medicines that were previously difficult or impossible to discover.

We are seeking an experienced, adaptable and hands-on HR Generalist (People & Culture Lead) to join us onsite in our Cardiff office. This is a broad HR generalist role with visibility to the leadership team, covering the full employee lifecycle, people operations, culture, performance, compliance, and day-to-day on-site support.

Join us to grow and evolve with a company transforming drug discovery!

Culture and Values

We believe in the power of autonomy nurtured in a culture with the following values. 

Own the outcome

We take responsibility for the result, not just the task. We act with urgency, clarity and accountability, especially when the work is hard, ambiguous or cross-functional. We do not wait for others to solve problems; we can help move forward.

Speak with care

We communicate clearly, honestly and constructively. We say the hard thing when it matters, but we do so with kindness, respect and care. Good intent is not enough; our words should help people make better decisions, improve the work and build trust.

Lead with curiosity

We are building in a space where many answers do not yet exist. We stay curious, challenge assumptions and follow the evidence, even when it takes us somewhere unexpected. We value scientific judgement, creativity and disciplined learning.

Build the system

We turn insight into repeatable capability. We do not rely on heroics where process, structure or better tools are needed. We create systems that make great work easier, faster and more robust for everyone.

Protect yourself first

We cannot protect the mission, the science or each other if we do not first protect our own capacity to think, care and contribute. We take responsibility for our energy, focus and wellbeing, and we support others to do the same. Ambition should stretch us, not break us. 

Role

This is not a narrow HR specialist role. It is a builder role for someone who can bring structure without bureaucracy, care without avoiding accountability, and pace without chaos. It has a direct career path to the Head of People and Culture.
