The work will revolve around the Galaxy application and supporting software with emphasis on DevOps and systems engineering. These positions seek someone who can:

  • Design and build cloud infrastructure necessary to allow Galaxy to operate on remote data and connect to remote compute resources;
  • Enhance the Galaxy Helm chart and Galaxy Kubernetes deployments for high-availability and self-healing;
  • Decompose Galaxy into service-based architecture to facilitate more federated approach to resource harnessing;
  • Integrate external authentication and authorization services and solution.


General Position Summary:
Responsible for the creation, implementation, maintenance, performance, production support and documentation of various research software. This includes but is not limited to the installation, modification, and testing of new and/or upgraded applications (packages or home grown), operating systems, file structures, hardware, communication devices, and productivity tools. Applies analysis techniques and procedures to gather and then translate user requirements into functional/technical specifications and designs.  Using functional specifications and designs, produces all or part of the deliverables.


Describe the position’s roles & interactions:

As an engineer on the Galaxy Team, you will be responsible for continuing to build support for running and using Galaxy on Kubernetes. This involves developing the Helm chart, designing back-end software to allow Galaxy to make better use of the Kubernetes-based deployments, run experiments to optimize user experience, finding emerging tools and methodologies and showing to the team how to integrate them into the existing systems and processes.


Describe the specific systems, applications, projects for which the position is responsible:

Galaxy application (galaxyproject.org), which is a software framework that (a) enables researchers to store, analyze, visualize and share genomic data and (b) provides genomic tool developers with the ability to deploy their tools within a complete analysis framework. Galaxy is an extremely popular data analysis platform with thousands of worldwide researchers using it on a daily basis.


Describe scale/size of area, project and/or system supported:

All work performed in the lab is open source and we are committed to the openness of scientific enterprise. Galaxy is written in Python and Javascript with vue.js while the support infrastructure relies on Helm, Kubernetes, Docker containers, and Ansible. We are looking to expand the capacity of the current application and provider better integration with other similar tools.
