Senior Cheminformatics Research Scientist

Your work will change lives. Including your own.

At Recursion, our mission is to transform drug discovery through a powerful synthesis of AI, automation, and deep scientific expertise. Cheminformatics is the backbone of our predictive and generative modeling capabilities, and our technology platforms are the engine driving drug discovery programmes with unparalleled speed and efficiency.

We are looking for a talented Senior Cheminformatics Research Scientist to be at the forefront of this mission. You will be instrumental in developing the scientifically intelligent automations that form our core discovery platform. Working with top-tier teams of drug designers, domain experts, and software engineers, you will design and implement the systems that power our programs. This is a unique opportunity to work at the cutting edge of AI-driven drug design and see the capabilities you build have a direct and immediate impact on discovering new medicines

In this role, you will:

• Use your technical foundation to make significant code contributions and collaborate across disciplines
• Ideate and develop new approaches to transform our core Hit Identification, Hit to Lead and Lead Optimisation processes by translating insights from drug designers and collaborating with domain experts in AI, Informatics, and Physics-based Modelling to build novel workflows.
• Develop and maintain the core cheminformatics capabilities and libraries routinely used by our drug designers.
• Collaborate with AI Research Engineers to enhance our generative approaches to molecule design.Collaborate within interdisciplinary drug discovery teams to advance pharmaceutical programmes
• Contribute to the design of AI/data science methods to expedite the Design-Make-Test-Analyze discovery cycle
• Lead the development of production-grade toolkits and libraries at the intersection of cheminformatics, computational chemistry, structural bioinformatics and artificial intelligence to continuously improve the productivity and capabilities of our drug discovery processes
• Define research and development priorities in the cheminformatics space including robust timelines and deliverables
• Collaborate with research scientists, medicinal chemists and computational drug designers to translate their requirements into algorithmic improvements and new capabilities
• Work with software engineers to implement these algorithms into our core technology platform
• Promote new methods through effective communication with stakeholders, training sessions and supporting users directly with their coding tasks
• Stay at the frontier of new technology developments, analyze them for potential benefits to our platform and devise plans for their implementation
• Be an external advocate for the company within the cheminformatics community
