Do you want to help us improve human health and understand life on Earth? Make your mark by shaping the future to enable or deliver life-changing science to solve some of humanity’s greatest challenges.

About the Role:

We are seeking a Senior Bioinformatician to join the Human Genetics Informatics (HGI) team at the Wellcome Sanger Institute.

The position is fixed term for 2 years.

You will be responsible for:
This role will involve working as part of the HGI team to deliver and optimise biological pipelines producing data for further analysis by human genetics faculty research groups. Key post holder responsibilities will be

  • Working with on-premise and cloud-based spark clusters to run Hail, a distributed Python library developed at the Broad institute (https://www.hail.is). You will be expected to use Hail to analyse variant data from very large cohorts, and produce summaries and visualisations to aid the Sanger institute scientists in their research. Examples of existing hail code are here: https://github.com/wtsi-hgi/exomeQC-hail-gnomad
  • Developing, running and maintaining bioinformatic pipelines (especially variant calling, RNASeq and scRNASeq pipelines). Examples of existing pipelines are here: https://github.com/wtsi-hgi/nextflow_ci/tree/rna_seq

  • Familiarity with one or more existing genomic variant callers (e.g. GATK)
  • Experience with large-scale genomic data analysis tools (e.g. Hail)
  • Understanding of web APIs to retrieve datasets from various web resources
  • Knowledge of virtualization/containerisation technologies (Docker, Singularity)
  • Knowledge (or experience) of Cloud environments (OpenStack, GCP, AWS)
  • Familiarity with Cloud technologies (e.g. Terraform, Ansible, Kubernetes, GitHub CI)
