We’re looking for the next member of the Software Development team. We build, operate and maintain metadata services that enable the global research community. We’re on a journey to build features to serve the evolving needs of our changing membership, and migrate our legacy technology. As a team, we have a deep understanding not only of technology, but also the needs of our diverse community.

You will specify, design and implement improvements, features and services. You will have a key voice in discussions about technical approaches and architecture. You will always keep an eye on software quality and ensure that the code you and your colleagues produce is maintainable, well tested, and of high quality.

Our new code is written primarily in Kotlin, on the back-end and Typescript on the frontend, and legacy code is written in Java. We don’t expect you to be familiar with our technologies yet, though it’s a bonus. This is primarily a back-end role.

You should have in-depth knowledge of at least one compiled, typed or functional language (e.g. Java, Clojure, Kotlin, Scala, C#, Go, Typescript etc) and a history of learning new languages and technologies on the job.

We are a geographically distributed, remote-first team with flexible working hours.

About the team

The Crossref team is distributed across the world. The Software Development team is based in Europe and the US. We work alongside the Product, Infrastructure and Labs teams.

All new code, and most issue tracking, is open source. We strongly believe in open scholarly infrastructure and openness at all stages of the software development lifecycle. We perform code reviews and practice continuous deployment for all new code.

As a membership organization we keep closely in touch with our users, and encourage our developers to be familiar with our community.

We work fully remotely, but try to meet in person at least once a year. This is a full-time position, but working hours are flexible. The applicant should expect they will need to travel internationally to work with colleagues for about 5-10 days a year. If you have any questions we would be happy to discuss.

You can be based anywhere in the world where we can employ staff, either directly or through an employer of record.
