Role Brief:

Competitive candidates will have a track record of writing and shipping quality, well-documented and well-tested software - preferably in the AI/ML industry. Candidates should be comfortable with modern, cloud-native computing, and with continuous development and production deployment on cloud platforms to large user populations. Educational or professional background in the biological sciences is a plus but is not necessary; passion to help therapies for new and existing diseases, and a pattern of continuous learning and development is mandatory.

The AI/ML team is built on the principles of ownership, accountability, continuous development, and collaboration. We hire for the long term, and we're motivated to make this a great place to work. Our leaders will be committed to your career and development from day one.

• Integration of AI/ML components with Front End, Back End, data and compute infrastructure
• Responsible for high quality software implementations according to best practices, including automated test suites and documentation
• Develop, measure, and monitor key metrics for all tools and services and consistently seek to iterate on and improve them
• Participate in code reviews, continuously improving personal standards as well as the wider team and product

• Sound understanding of web development best practices, modern design principles, and continuous integration workflows
• Knowledge of agile practices and able to perform in agile software development environments
• Strong knowledge of modern software development tools/ways of working (eg git/GitHub, DevOps tools for deployment) - should be able to show practice of commit early and deploy often

Preferred qualifications:

• Experience with Docker or containerized applications, especially architecture of multi-container applications
• Demonstrated experience with biological or scientific data (eg genomics, transcriptomics, proteomics), or pharmaceutical industry experience, especially design of data visualisations
• Knowledge of agent-based approaches (eg LangGraph, PydanticAI, AutoGen)
