What we do


Ably’s engineering team is deeply technical, collectively bringing a wealth of experience and broad technology skills across infrastructure, security, distributed systems, and much more. The calibre of the code we produce is what excites and motivates us each day. If you enjoy solving hard distributed system problems that are mostly platform agnostic and theoretical in nature, then you'll love working at Ably.


In this role

You will be responsible for hands-on development and leading the web engineering team to deliver our website, developer dashboards, common services, and provisioning APIs that our customers, developers like yourself, depend on.


You will be successful if you:

  • Primarily like to be hands-on writing code, yet also enjoy mentoring and leading a team of web engineers.

  • Like to see a feature delivered end-to-end, ensuring the backend code is robust, the test coverage is thorough, and the frontend and developer experience is rich and enjoyable for our customers.

  • Care about code quality, architecture decisions, and enjoy collaborating with a deeply technical team to solve the hard problems we face providing our distributed messaging system.


Requirements

Technical skills needed:


  • Ruby. A minimum of six years professional experience using Ruby. 

  • Rails and web development. A minimum of six years of professional experience with Rails development. Although your focus will likely be primarily on the backend, you must be a proficient full-stack developer using HTML, CSS, Javascript. Experience using at least one frontend framework such as React or Angular required.

  • Testing strategies. You must have a strong working knowledge and experience of continuous integration and testing frameworks with a pyramid approach (unit testing, integration testing, acceptance testing, etc).

  • Architectural design and design patterns. You should have experience leading architectural decisions for large web applications, and be well versed and a strong advocate of design patterns, where applicable.


Nice to have skills:


  • Experience delivering developer-focussed APIs, including API design, documentation and scaling.

  • Experience with infrastructure and distributed systems is beneficial.

  • Knowledge of realtime, event-driven and streaming protocols.

  • Experience with any of the other languages we use extensively at Ably: Node.js, Elixir or Go

  • Our team are active open source contributors and are encouraged to do this as part of their role at Ably.  We like new team members who enjoy contributing back to the open source community, even if those contributions are small. 

  • Good grasp of Agile, Kanban and SCRUM.

What’s it like to work at Ably?


Founded by two engineers who spotted a hard and largely unsolved problem, Ably is, at its heart, an engineering company.

As a company and engineering team we’re committed to a future internet that’s open and Ably’s engineers contribute to existing open source projects. See https://go.ably.io/open 


We want to work in a company of inclusive people who treat each other well. We’re building a company with a diverse set of people who value:



  • Ownership and impact of work. You have real autonomy and ownership over your work with a visible impact inside Ably, and externally on products powered by Ably that you use in your daily life.

  • An environment to thrive. Modern, comfy office in the heart of Camden. Excellent transport links, Camden Food Market with over 100 food stalls and restaurants, and multiple work spaces to match your working style.

  • Truly flexible working and not just lip service. Come into the office, work at home, or rock up at your local coffee shop at the hours you focus best.

  • Work is varied and challenging as we’re solving hard, complex problems that push the limits of what’s possible with today’s software and infrastructure.
