About this role

Ably is an engineering company at its heart. Our audience ranges from software engineers to CIOs and it's our job to make sure the world knows about Ably.

Ably's aims are to create technically products and features, and we have a newly formed R&D function to establish the technical underpinnings for future product development. You will belong to the R&D team working under the direction of Ably's Co-founder and Chief Scientist. You will contribute to all of the aims of the R&D team, which include:

  • Build awareness of the technology landscape by evaluating new technologies, approaches, academic and other research results, and software offerings;
  • Undertaking applied research and development directly, creating and developing new concepts and approaches as software deliverables;
  • 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.

We are looking for candidates who have an established interest in distributed systems who can contribute to these aims.

Day to day, you will

  • Work as a software developer on new features or other enhancements related to the Ably product, working both on existing codebases and green-field projects.
  • Review, and gain a theoretical and practical understanding of technology developments that are potentially applicable, whether those are other research outputs, open source software projects, or product offering.
  • Create original contributions, either theoretical or practical, to address specific product challenges.
  • 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.
  • Support realisation of the results of R&D as project features, working with the engineering and product teams.

We'd love to here from you if

  • An active interest, and experience working on, distributed systems problems. Find out what it takes to be a distributed systems engineer.
  • Backed by an academic background in Computing Science or Maths.
  • Professional development experience in Go and Nodejs.
  • An excellent practical understanding of distributed systems software, networking, protocols and systems programming.

It would be nice, but not essential if

  • Experience of building and operating production systems at scale.
  • Experience in a research setting involving topics relevant to our product including realtime and distributed systems, protocols, collaboration and associated technologies.
