Senior Full-stack Web Developer

Your role

This is an exciting opportunity to make a significant contribution by delivering data portals for several world leading projects tackling global sustainability and biodiversity challenges including:

• Ancient Environmental Genomic Initiative for Sustainability
• Functional Annotation of Animal Genomes (FAANG)
• European Reference Genome Atlas
• TRansversing European Coastlines

You will be responsible for support and development of software to handle data curation, coordination, validation, distribution and visualisation of agriculture, aquaculture and biodiversity data. You will work with large scientific communities to define and implement metadata standards, develop software to validate and improve data descriptions and develop, build new project specific portals, and extend existing web data portals to meet the specific needs of each consortium.

The data portals will include Application Programming Interfaces (APIs) and bespoke data visualisation and presentation solutions. You will also contribute to our growing "question in ? insight out" initiative, exposing consortium data through MCP servers and agent-based interfaces so that researchers can ask scientific questions in natural language and get back analysis, not just download links. You will also support efforts for the development of standardised containerised workflows and cloud platform integration.

As part of this team, you will have many opportunities to engage with data generators, project users, and collaborators, to which you will provide guidance and support on utilisation of the team's software and support users to provide rich metadata descriptions. You will work with a range of data archives at EMBL-EBI, including the ENA and Bio Samples, to support each project and community in sharing and gaining access to well described, high quality sample and genomic data.
