mandag 30 apr 18

Are you a skilled Open Source Developer of web-based solutions? Do you want to be a part of a development and operations team anchored at one of Europe’s most ambitious research libraries?

You will join our 13-strong Library Systems team, which consists of developers, ops and project coordinators. DTU Library has 45 colleagues in total, and together, we push the limits for how a modern digital research library serves its users.

As a team, we are jointly responsible for maintaining the two primary digital library components: The Library Services Platform & Discovery Service (DTU FindIt; and the DTU Research Database (DTU Orbit; We are also responsible for supporting adjacent systems, applications and the necessary infrastructure beneath these services—an infrastructure designed to meet the demands for scale, throughput, performance, and elasticity.

The job
You will be working with creating, improving and sustaining our services to our users. Optimization—often at a scale outside what is usually described in textbooks—is a common part of this. Adjusting the content and/or configuration of our Apache Solr instance (currently loaded with ~200M documents) while not losing service, is not an uncommon subtask.

The team has a balanced mix of competences, and teamwork is essential to our everyday activities. Collaboration with stakeholders is key in relation to colleagues in the other teams and the management of the library, and often also with external colleagues anchored with international as well as national partners.

The environment
We develop and operate web applications enabling our users to service themselves to the largest extent possible, and interface with the librarian-based support services when they cannot. Enabling easy discovery (search and delivery) in the global corpus of relevant literature is a big part of this.

Our technical environment local and dominated by Open Source software, typically (co-developed in collaboration with communities of likeminded university libraries (national as well as international). We currently use Ruby on Rails, Blacklight, Apache Solr, Hydra, Fedora Commons, Java, Debian GNU/Linux supplemented with Pure, SFX, and EZProxy. We focus strongly on continuous integration/delivery and automation, currently using tools and technologies such as Docker, Puppet, Gitlab, and Redmine.

Primary areas of responsibility
You will:

  • Work with your immediate colleagues to develop and maintain existing web-based services and bring about new ones, ensuring the highest quality experience for our users
  • Apply best-practice web virtues, web methodologies, and web technologies to our applications
  • Participate on our journey to transform today’s infrastructure and solutions exposing predominantly bibliographic objects to also support the rapidly emerging phenomena in the Open Science of tomorrow (Research Data, Linked Open Data, etc.)
  • Utilize your experience in collaboration with other teams to take our web-based service to the next level
  • Work with and keep yourself updated on trends and developments in Open Source, Search and other library-relevant technologies/methodologies.
Our expectations of you

  • Move around natively in a Linux/Open Source environment
  • Be a skilled Ruby programmer – or have a desire to become one
  • Be passionate about programming and understand the role, potential, and limitations of homegrown/-operated software in an organization

  • Know how to ensure smooth and automated deployment of multi-branched, flexible development and operational environments, and why this matters to efficient service development and maintenance - experience with automation, Puppet and Docker is a plus
