Go Developer (Remote)

Job description

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

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 ably.com/careers 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

We are seeking a software engineer who is interested in working across a variety of programming languages and environments, with a focus on Golang. You will join our friendly and creative team, helping us to deliver easy-to-use APIs that enable application developers to build robust solutions that rely on real-time data delivered by our cloud service.

Developers interact with our service, for the most part, using our client library software. This type of software, more often referred to as a software development kit (SDK), accelerates the development of servers and client apps that interact with our service. All our SDKs are open source and available on GitHub. We are receptive to contributions from our customers, the developers they work with and the wider open-source community.

Day to day, you will:

  • Manage the full lifecycle of client library software, including the development of new features, maintenance, bug fixing and testing.

  • Cooperate with other developers, collaborating to solve problems and deliver best practice. Activities include commentary on public pull requests and issues, as well as participation in internal Slack channels.

  • Formulate API proposals and the published specifications for new features, including liaison with the customers requesting them.

  • Provide support to our developer community, resolving issues raised against our client library SDKs.

What we look for:

The nature of this role is diverse by definition. We have an idea of some of the skills and experience which might help you perform well as an SDK Developer at Ably, but we believe the most important thing is that you have a desire to evolve your skills and adapt your techniques as the role grows with you.

We would like to see:

  • Programming Languages: A range of software development experience, including time spent developing with Go, aligned with a desire to produce idiomatic Golang code. It would also be nice to see that you have written code in other languages, including in some of those that we work with, including Python, PHP, Ruby, Dart, Swift, Kotlin, C#, JavaScript, TypeScript, Java and Objective-C.

  • Runtime Platforms: Customers use our SDKs from a number of runtime platforms - ranging from servers to the laptops, PCs, tablets and phones owned by their users. We have to provide the tools and support for this diverse range of runtime environments, so what can you bring to the team? We don't expect you to know everything but we do need you to be enthusiastic to learn when required.

  • Networking and Protocols: Some depth of knowledge around network transports as well as data / message packing. We use HTTP and WebSockets as well as JSON and MessagePack. It would be great if you've had some experience of writing software that implements a protocol.

  • Testing: An understanding of asynchronous testing, in particular system / integration testing of software making network calls. Additionally, an eye for opportunities to layer testing so that portions of the codebase can be validated using pure unit tests.

  • Open-source Software (OSS): We understand that contributing to the open source community may be something you've not had the opportunity to do yet. It's a luxury that not many jobs offer and which many people don't have the free time to participate in either. However, if you have been able to get involved in open-source, then we would love to see what you've worked on.

We want to work in a company of inclusive people who treat each other well. To really thrive at Ably, you’ll need to believe in and be prepared to do your work in line with our values, which are:

  • 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.
