  Research software -- specialist software used to support or undertake
research -- is of huge importance to researchers. It contributes to significant
advances in the wider world and requires collaboration between people with
diverse skills and backgrounds. Analysis of recent survey data provides
evidence for a lack of diversity in the Research Software Engineer community.
We identify interventions which could address challenges in the wider research
software community and highlight areas where the community is becoming more
diverse. There are also lessons that are applicable, more generally, to the
field of software development around recruitment from other disciplines and the
importance of welcoming communities.
