The Ontario Institute for Cancer Research (OICR) is seeking a passionate developer to join the Genome Sequence Informatics (GSI) team.

GSI designs applications to streamline and automate analysis for the Genomics program (, controls the data life cycle, and creates useful and dynamic reports at scale. We ensure data flows smoothly, securely, and correctly from the lab through to the clinicians and researchers who use it. Our primary languages are Java, Python, Javascript, MySQL, PostgreSQL, and MongoDB and we use technologies like Docker, OpenStack, Prometheus, Loki, Promtail, and Univa Grid Engine, and are expanding into Cloud environments like Microsoft Azure. Many of GSI’s software projects are open-source and available on GitHub: and

GSI has three sub-teams:

  • Infrastructure: Includes laboratory tracking, pipeline and data management, and reporting. This team develops the open source MISO LIMS ( and associated applications, workflow systems like Vidarr and Cromwell ( to automate and streamline data analysis, tracking, and workflow management, and maintains a suite of specialized reports for quality control, forecasting, and lab operations.
  • Analysis: Bioinformatics analysis and data release. Develops the analysis techniques and pipelines used by OICR Genomics for alignment, de novo assembly, variant detection, quantification of tumour heterogeneity and purity, RNAseq analysis, variant significance prediction, structural variant calling, immune detection, cfMeDIP, and others. This team also archives data for long-term storage and releases data to collaborators and public archives.
  • Cancer Genome Interpretation: Validates pipelines for accreditation, analyzes and interprets genomic data using accredited pipelines and processes, and drafts reports for clinical cases.

Software developers in GSI are enthusiastic and autonomous. As part of the team, you will be involved in all aspects of development of new applications for high-impact cancer research and clinical reporting, as well as monitoring, diagnosing, and pushing fixes to improve stability and performance of existing applications. You will develop and improve our production system within a research environment.

While most work is completed remotely, we occasionally have in-person meetings and events. You’ll also have the opportunity to participate in onsite team and organization wide social activities and attend seminars and presentations on the latest in cancer research.

This position is temporary, full-time for one-year.
