COSMIC is the key information source in global human cancer research and is growing rapidly in content, scope and its value. This role will require the evolution and expansion of our web services and products to enable this growth. Our web team puts emphasis on applying best practices, writing clean code and taking a test-driven development approach. COSMIC is expanding its range of web applications which requires innovative backend development, complex processing of data and RESTful APIs for both internal and external consumption.

COSMIC data is gathered from a variety of sources, from manual curation to structured repositories, and standardised into the COSMIC database before release via our analytic website. This genetic and genomic data is increasing in quantity and scope, its value is enhanced by analytic highlights, and this position will improve the handling, meaningful presentation and user access of this information.

About You:

You will be passionate about writing clean, high quality, readable and maintainable code to support our growing suite of products. You must be a good communicator and able to understand the goals and aims of the collaborative COSMIC team and its customers of researchers, scientists and clinicians, globally. You should be comfortable working within a Unix/Linux environment. You will understand what makes a good API and have experience in both consuming and delivering such APIs via the web. Familiarity with Python web frameworks such as Django or Flask are a must. Understanding of performance and algorithm complexity would also be appreciated. You will have experience working with relational databases spanning large and complex datasets, ensuring throughput and quality. Apart from your development skills you will also be expected to contribute as DevOps to the packaging, deployment, security and monitoring of our infrastructure. You will have an interest in DevOps, CICD, Docker and cloud-based deployment including Kubernetes. This role has great scope for expanding your skills, knowledge and interests.
