Senior Software Engineer, Backoffice Platform

div class= content-intro p Our everyday digital experiences are in the middle of a realtime revolution: chatting alongside a livestream, getting realtime financial updates, or working with colleagues in a shared online space. Consumers now expect realtime as standard, and Ably powers a large part of it. /p p We put developers first. Our products help teams build, extend, and deliver realtime digital experiences, delivering over 700 billion messages to more than 2 billion devices every month. Teams at HubSpot, Fin, Dialpad, NASCAR, Sportsbet, and General Motors all build on Ably. /p p Working at Ably means helping build the infrastructure that will shape the next generation of the internet. More of what people do online is becoming live, shared and interactive, which only makes what we build more relevant and more necessary. AI is the latest place that shows up. There's still so much to build, and we'd like your help with it. /p /div h2 strong About this role /strong /h2 p Ably's back office platform is where every customer account is managed. It holds the packages, entitlements and limits that determine what each of our customers can do, and it runs the tooling our Finance, Customer Success and Support teams rely on every day. /p p This is an opportunity to take ownership of a platform the whole business depends on, with the scope to decide how it should work rather than maintain someone else's decisions. You'll be hands-on across entitlements, administration tooling and billing, working closely with our Head of Infrastructure and our Developer Experience team, and directly with the teams who use what you build. /p p We work in an AI-first engineering culture: AI tools are part of how we plan, prototype, and iterate, though engineers own every technical decision, and human judgment is the quality bar that everything is measured against. /p h2 strong Day to day you will /strong /h2 ul li strong Run the back office platform. /strong You'll look after the systems holding every customer's packages, entitlements, limits and billing, along with the tooling Finance, Customer Success and Support use daily. /li li strong Solve problems, not tickets. /strong You'll be handed a problem, usually described by the people living with it rather than specified in advance, and you'll own the design as well as the delivery. /li li strong Make admin work for the people who use it. /strong Staff should be able to see what a customer has bought, how they're billed and what limits they have, make a change, and trust the result, without needing to understand our internal models. /li li strong Partner across the company. /strong Finance, Customer Success, Support and Engineering are all your users. You'll learn their processes well enough to question a requirement rather than just build it. /li li strong Champion AI-assisted development. /strong You'll use LLMs and AI tools for planning, spikes, code and docs to accelerate velocity, while owning correctness and architectural quality yourself. /li li strong Make the systems explain themselves. /strong Why a customer has the limits they have, and what produced an invoice, should be answerable without an engineer digging through code. /li li strong Set the testing bar. /strong You'll decide what good looks like where mistakes cost money, build the harness to match, and hold the line on production readiness. /li /ul h2 strong We'd love to talk if you have /strong /h2 ul li Experience working in large, established codebases, and the judgement to tell when a system should be extended, reworked, or replaced outright, including the confidence to say so unprompted. Ruby on Rails will help you get to grips with what we have today, though we care more about your range than any one language, and what you build here may well not be Rails. /li li A track record of shaping architecture inside a system you inherited, including the data ownership decisions that come with drawing a boundary. /li li The ability to self-start, work through ambiguity, and make good decisions without a lot of hand-holding. We'll bring you problems, not designs, and we'd expect you to push back when the answer is to change a process rather than write code. /li li An AI-first mindset. You see LLMs and AI tools as productivity multipliers and know where to apply the rigour they can't provide themselves. /li li Experience making systems observable and testable. You instrument what you own, use it to answer questions you never designed for, and have set a test strategy for a system with patchy coverage. /li /ul h2 strong Bonus points if you have /strong /h2 ul li Experience of usage-based billing systems, whether built in-house or on a platform such as Orb, Metronome, or Chargebee. /li li A background in platform or internal tooling teams rather than product teams. /li li Experience being the engineer accountable for a system rather than one contributor among many, particularly one subject to financial or compliance audit. /li /ul div class= content-conclusion h2 strong What’s it like to work at Ably? /strong /h2 p You'll join a team of around 60 people, working directly alongside senior engineering and leadership. No layers, no bureaucracy, and real ownership from day one. /p h3 Remote-first /h3 p We hire the best people wherever they are across the UK and Europe, trust them to own their work, and share decisions and feedback openly. Twice a year, in February and August, we all meet in person, and we expect everyone to be there. /p p Remote-first comes with trade-offs. On one side: flexibility, no commute, long stretches of focus time, and a wider pool of people to hire from. On the other: it can feel isolating, relationships take effort to build, and you miss the chance conversations an office creates. As our only recruiter, you'll need to manage your own time and stay close to the hiring managers and candidates you work with. /p p If you do your best work with trust and autonomy, this will suit you. If you'd rather have an office around you every day, it probably isn't the right fit. /p p Our six values shape how we work day to day: /p ul li strong Open for all. /strong We default to sharing openly: source, decisions, and feedback, with open minds to match. /li li strong Tech needs humanity. /strong We build with empathy, for colleagues and developers alike. /li li strong Even the best do better. /strong We keep raising our own bar, driven by curiosity, not complacency. /li li strong Bias for action. /strong Once we know enough to act, we act, rather than waiting for certainty. /li li strong Dependable by default. /strong We take real ownership of what we ship and what we promise. /li li strong Bold creativity wins. /strong We treat big constraints as a reason to think differently, not less. /li /ul p You can read more about how we defined these values on a href= ably.com/blog/ably-values our blog /a , and see the team behind them on our nbsp; a href= ably.com/careers careers page /a . /p h2 Diversity, inclusion, and belonging at Ably /h2 p We believe our differences as individuals are what make us great. Our people are at the heart of what we do, and we encourage everyone to be their most authentic self at Ably: we see inclusivity and openness as fundamental to our long-term success. We encourage applications from all backgrounds regardless of age, disability, gender, sexual orientation, parental status, race, religion, educational background, or neurodiversity. Ably has an amazing opportunity ahead of us, and we want anyone to be able to contribute to it. /p p em If you enjoy working as part of a technology company, value open source, and love solving hard problems, we'd love to hear from you, regardless of whether you fit the job description exactly or not.
