• Attend regular OPP meetings and contribute to programme strategy.
• Writing clean, efficient and readable code to support our Python based data pipeline.
• Contributing to the codebase of our GraphQL API, which is being rewritten in Rust.
• Supporting our GCP infrastructure, deployed with Terraform and Helm.
• Taking ownership of the design and development of new features and pipelines.
• Resolving complex issues with independent problem‑solving and self‑management.
• Assisting the Open Targets data team on the execution of our data pipelines for regular release cycles of the Platform.

You will have:

• Qualifications in computer science, software development, or a related field.
• Good day‑to‑day computer engineer knowledge: building and designing software, CI/CD tools, Git skills, debugging methods and comfort with frequent deployments.
• Expert Python knowledge and familiarity with the modern python ecosystem tools like uv, ruff, and type annotations.
• A good grasp of modern statically typed programming language paradigms, Rust being a valued plus.
• Experience in a cloud environment.
• Experience in independent problem‑solving and examples of resolving complex issues.
• Fluency in written and spoken English.
• Ability to effectively communicate ideas or issues to those with technical and non‑technical backgrounds.
• A collaborative attitude and work well with team members from multidisciplinary backgrounds.

You may also have:

• Experience with NoSQL (OpenSearch) and SQL (ClickHouse) databases.
• Experience working flexibility, remotely, and adapting quickly to changes in priority in an agile environment.
• Previous experience working in the research or life science industries.
• Knowledge of human genetics, genomics, and/or drug discovery and mental health/psychiatric conditions; or interest in learning about these topics.
• Previous experience working with sensitive clinical data and data containers.
• Interest in promoting your work and the ways we have solved complex challenges.

We are open to applicants at different career stages, but we are keen to find someone who wants to work with modern technologies and embrace industry standards in order to tackle complex challenges in large‑scale data, drug discovery and informatics and has an interest in working within a project team to address the needs of the psychiatric disease community.

Additional Information:

• Our flagship application, the Open Targets Platform, is open‑source and powered by a Python data pipeline running on Apache Airflow.
• The data is served by a Scala API that we are rewriting in Rust; and displayed in a modern React Web Application.
• The whole stack lives in Kubernetes clusters hosted on Google Cloud Platform; and we are using Prometheus, Grafana and Loki to provide observability on it.
• You will be based at EMBL-EBI on the Genome campus, Hinxton, and will also be required to attend meetings with the OPP team members, project stakeholders and occasionally patient groups (who will contribute to project development) at Addenbrookes Hospital, Cambridge.
