Software Development Engineer

We are building the platform that holds every molecule our researchers design, make and test. As a Senior Software Development Engineer, you will help consolidate our molecule registration systems into a single cloud-native platform at the centre of our AI-driven drug discovery work. You will write the code that lets computational design and laboratory science iterate on each other, at a scale of hundreds of billions of records.

The Opportunity:

• You develop and maintain core features of our Therapeutic Molecule Registration platform, working primarily in Python alongside Java and Kotlin components.
• You design and implement RESTful APIs and microservices that serve molecular data to research and machine learning teams across our global organisation.
• You write high-quality, testable code for chemical registration workflows, where correctness directly affects the science that depends on it.
• You shape architecture by contributing to technical design discussions as multiple registration systems are harmonised into one.
• You build for scale and speed designing cloud-native systems that support rapid iteration between computational molecule design and experimental validation.
• You work alongside scientists partnering with our Computational Sciences colleagues, our machine learning for drug development team, and Drug Discovery groups including Antibody Engineering.
• You grow into a new domain combining software engineering craft with chemical and biological data management — we will support you in learning it.

Who you are:

• You hold a degree in Computer Science or a related field, or you have built equivalent expertise through practice. (Required)
• You are a strong Python programmer with significant experience building and running production services, and you can work confidently in existing Java or Kotlin codebases. (Required)
• You have deep working knowledge of Postgres and SQL, and you design REST APIs and microservices that hold up under load. (Required)
• You treat testing as part of the work, with a strong track record in test automation, CI/CD pipelines and agile delivery. (Required)
• You have built on cloud platforms, preferably AWS, and you are curious about scientific data — you enjoy learning a domain deeply enough to design well for it. (Required)

Preferred:

• Open-source cheminformatics experience — RDKit, chemfp, Indigo or the HELM toolkit — chemical database cartridges, structure canonicalisation, or molecular structure searching.
• Familiarity with chemical and biological structure notation, or with biological sequence alignment.
• Docker and Kubernetes, event-driven architectures, or a background in scientific software development.

Every molecule registered on this platform is a possible medicine, and the speed at which we can find it depends on the systems we build. If you want your engineering to shorten the distance between an idea and a therapy that reaches patients, apply now.
