  • Advance Ably's community presence and standing by a combination of research publications, blog posts, conference presentations and open source software offerings, where these are relevant to the R&D plans being undertaken.

  • Produce research outputs ranging from conference or journal papers, blog or other online content, to open source software.
  • Participate in customer and market research to understand our use-cases for Ably's projects, including talking directly to developers within Ably's customer community.
  • Analyse Ably's existing code and services, to understand its behaviour, design features and limitations, and its operation in practice.
