Isomorphic Labs is applying frontier AI to help unlock deeper scientific insights, faster breakthroughs, and life-changing medicines with an ambition to solve all disease.

The future is coming. A future enabled and enriched by the incredible power of machine learning. A future in which diseases are curtailed or cured starting with better and faster drug discovery. 

Come and be part of an interdisciplinary team driving groundbreaking innovation and play a meaningful role in contributing towards us achieving our ambitious goals, while being a part of an inspiring and collaborative culture.

The world we want tomorrow is the one we’re building today. It starts with the culture at this company. It starts with you. 

Isomorphic Labs (IsoLabs) was launched in 2021 to advance human health by building on and beyond the Nobel-winning AlphaFold system. Since then, our interdisciplinary team of drug discovery experts and machine learning specialists has built powerful new predictive and generative AI models that accelerate scientific discovery at digital speed.

Our name comes from the belief that there is an underlying symmetry between biology and information science. By harnessing AI’s powerful capabilities, we can use it to model complex biological phenomena to help design novel molecules, anticipate how drugs will perform and develop innovative medicines to treat and cure some of the world’s most devastating diseases.

We have built a world-leading drug design engine comprising AI models that are capable of working across multiple therapeutic areas and drug modalities. We are continually innovating on model architecture and developing cutting-edge capabilities to advance rational drug design.

Every day, and with each new breakthrough, we’re getting closer to the promise of digital biology, and achieving our ambitious mission to one day solve all disease with the help of AI.

 

We are a dynamic team of Medicinal Chemists transforming how drugs are designed. By partnering deeply with our AI/ML colleagues, we are doing more than just leveraging the Isomorphic Labs drug design engine - we are actively shaping it. We use our domain expertise to challenge and refine our algorithms, creating a powerful symbiotic relationship that drives our internal and collaborative portfolios. Our team work closely together in a supportive environment, where everyone is valued for their medicinal chemistry expertise and experience they bring to the group. We have a strong growth mindset and prioritise continued development and learning.

As part of the ongoing expansion of our Drug Design and Medical Research function, we are hiring Medicinal Drug Design Leads. You will work as a Chemistry Lead, delivering scientific expertise and strategic direction to fulfil milestone objectives on our portfolio projects. You will support the business alongside world leading AI/ML Drug Design Platform teams, and will work collaboratively to drive improvements in the platform and apply these to impactful drug design projects. Please note that this is a scientific leadership role, where you will take an active hands-on role as an individual contributor rather than being a people manager, although you will support and mentor junior colleagues.

If you are a skilled Medicinal Chemist with a passion for applying cutting-edge technology to complex scientific challenges, this role offers an unparalleled opportunity for impact and growth.
