    Position: Senior Cloud Software Developer/Architect
    Site: MaRS Centre, Toronto
    Department: Informatics & Biocomputing
    Reports To: Manager and Senior Software Architect
    Salary: Commensurate with level of experience
    Hours: 35 Hrs/week
    Status: Permanent, Full-time

    The Ontario Institute for Cancer Research (OICR) is looking for a Senior Software Developer to contribute to the technical development of the Informatics and Biocomputing platform. This full-time position is primarily focused on planning the architecture and building the cloud-based software infrastructure to support the Cancer Genome Collaboratory. Collaboratory will create a cloud-based computing facility for integrating and advancing technologies for manipulating, managing, and analyzing huge genomic data from thousands of individuals taken from the International Cancer Genome Consortium and other sequencing projects. This position will create secure and scalable, cloud-based software tools to support the analysis of upwards of 15 petabytes of cancer genomics data corresponding to 50,000 genomes.

    Our software infrastructure is built upon distributed and scalable frameworks such as Hadoop, Cascading, HBase, Elasticsearch and MongoDB. Our RESTful web applications are based on AngularJS, D3.js and other popular open source JavaScript libraries. Our development/deployment environment is using Maven, Jenkins, Artifactory, OpenStack and Ansible. The current ICGC infrastructure consists on a cluster of 101 nodes of 64 to 128 GB of RAM and 3-12 TB of local storage.

    The responsibilities include:

    Leading architectural design and prototyping for an analytical infrastructure provisioning process built on top of OpenStack (and AWS) cloud technologies
    Advancing software tools for performing cancer genome analysis in a cloud environment
    Liaise with end-users and distributed team members in order to resolve issues and integrate existing software tools
    Provide guidance to more junior team members and help lead their development
    Implement back-end software to support projects such as a user-portal for accessing genomic data, management tools for tracking usage and costs, and high performance, analytical workflows running on the Collaboratory cloud infrastructure
    Follow excellent coding practices for open source development (manage code in source control, write unit and regression tests, provide documentation on both public and private sites)


    Have strong opinions about robust, usable, and maintainable software
    Strong expertise in Java and associated open source libraries such as Apache Commons and Guava
    Experience with build tools such as Maven and source control using git
    Working experience in web service architectures (RESTful, XML, JSON)
    Experience with using and managing hundreds of VMs using software such as Ansible, Chef, Puppet
    Experience in writing unit and integration tests using JUnit and Mockito
    Experience profiling and benchmarking applications
    Desire to contribute to all parts of the development process
    Desire to work in a production scientific environment and in bioinformatics
    Knowledge of bioinformatics is an asset but not essential
