About the role

This role provides a technology cornerstone to our development team responsible for the ongoing development, maintenance, and operation of our Content Registration system. Metadata is critically important to Crossref’s mission to make research communications better, and the registration system is where it all starts. You will report to the director of technology, joining a team of three developers and one system administrator. You will also work extensively with all other teams across our small but impactful organization.

Our stack is mainly a backend system written in Java on Spring and utilizing SQL on MySQL and Oracle. We’re still running our own hardware but are moving to AWS and already use S3, RDS, and other Amazon services. You will be responsible for ensuring that the Content Registration system is reliable and responsive as well as making sure it is able to evolve quickly to support the new requirements and new services that we are developing for its membership and metadata subscribers. As such, you will need to work closely with product management and the strategic initiatives teams.

This position also provides programming and workflow guidance to the entire team by guiding concept formulation, design, and implementation. Our processes are built on Jira, SVN, Zendesk, and Git and we’re starting to use agile methods. We communicate via Slack and Google apps. You will help improve our quality control initiatives, review methodologies and help develop a culture of continuous testing and deployment.

Your challenge will be to accomplish this, whilst simultaneously driving the modernization of our current software stack, infrastructure, and software engineering culture.
