Senior Frontend Engineer (Remote)

Job description

Location: Remote, mainly UK based, as travel to our London hub will be required once a month.

Team: Website Engineering

As Ably enters its next stage of growth, we’re looking for talented and curious engineers to help us build and deliver the platform to power synchronized digital experiences in realtime for one billion devices every month by 2023.

Our everyday digital experiences are in the midst of a realtime revolution. Consumers expect realtime digital experiences as standard and synchronized data in realtime is business critical for many organisations. Yet, at the same time, organizations don’t have the in-house capabilities nor the time to do this efficiently at scale. That’s where Ably comes in.

We provide a suite of APIs to build, extend, and deliver powerful digital experiences in realtime for more than 250 million devices across 80 countries each month. Organizations like Toyota, Bloomberg, HubSpot, and Hopin depend on Ably’s platform to offload the growing complexity of business-critical realtime data synchronization at global scale.

But we can’t rest yet. And we’d like your help.

To see what life’s like at Ably, check out our careers page at and read the story of how Ably's core values came to be.

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 helping shape the future of our frontends, making decisions that have a long lasting impact, and helping your peers grow their frontend knowledge and experience. You’ll be working alongside a team of engineers that have a broad range of expertise across the web stack, all working together to deliver the valuable features and improvements our customers expect from us.

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.

Day to day, you will:

You’ll be hands-on with development and assisting your team to build and deliver improvements and new features to our website, customer dashboards, and internal tools. You’ll be helping steer the direction of our component library, used by multiple teams to deliver a consistent identity for Ably no matter where people see us online.

Work with your team across the entire web stack, sharing with and learning from each other. We believe in working together closely, balancing asynchronous work and remote pairing. We also believe in delivering high quality work, so we hold each other accountable just as much as we support each other.

You’ll be working closely with our product & design teams towards achieving the strategic goals of the company. You’ll also work with people all across Ably as the projects we work on touch many different parts of the company.

We’re continually improving, whether it is deliberately refactoring code to make our lives easier or updating our ceremonies to be more useful, and as a senior engineer you’ll be expected to contribute these kinds of improvements to the team.

It would be great if you have:

  • Strong HTML, CSS and Javascript. Some knowledge of modern standards (ES6+, CSS Grids, Fetch), best practices (Accessibility, SEO, Performance, Security), frameworks (React, Gatsby, or Angular), bundling (Webpack) and modern approaches to CSS (Styled Components, TailwindCSS). Deep experience in a few of the aforementioned concepts and technologies is a requirement.

  • Architecting frontends. Experience with designing and implementing frontend architectures, like component libraries, SPA’s, and server-side rendered applications.

  • Full-stack mindset. You’ve built full-stack applications with CI/CD, as well as understand and promote the importance of the latter.

  • Testing strategies. You must have experience with writing automated tests for software with tools like Jest or Cypress.

  • Component libraries. Experience building and/or working with a component library.

  • Cross-functional team experience. You worked closely with designers and product managers in short, effective feedback loops.

  • Good grasp of Agile, Kanban and SCRUM. Working with stakeholders to create and manage backlogs, working with the team to manage the delivery of work

It would be nice if you have:

  • Experience delivering developer-focussed products or services

  • Experience with Ruby on Rails

  • Knowledge of realtime, event-driven or streaming protocols

  • An interest in functional programming with Elm or ClojureScript

  • Experience with mentoring less experienced developers

  • Bias for action. We avoid analysis paralysis at all costs. We lean into doing in order to move us forward. When we have enough of what we need to act, we act.

  • Even the best do better. We want to be the best - but that doesn’t mean we rest when we are. Improvement and growth - true betterment - is an ongoing journey. One fuelled by curiosity and taking risks.

  • Technology needs humanity. Our technology means little without people - whether that’s how we treat our colleagues, or how we design developer experiences. Being human matters.

  • Dependable people make dependable things. Dependability is integral to our mission and technology, but being dependable starts with our people. When we care enough to take real ownership of our products and problems - all else will follow.

  • Bold creativity leads to the greatest rewards. When viewed through a different lens, what stands in the way can become the way. The bigger the challenge the easier the choice: bold creativity will always move us forward, create better outcomes, and set us apart.
