Senior Backend Engineer – Remote across UK & Europe Tech: Kotlin, React, Postgres and AWS They’ve built something that makes accountants say, “I didn’t think this was even possible.” And they’re just getting started. This isn’t maintenance work or fixing spaghetti left by the last engineer. It’s new product build. You’ll be delivering features, reducing tech debt, and shaping the backend foundations for a platform taking on the likes of Oracle, NetSuite and Xero. They already have the design and frontend nailed. What they need now are backend engineers who can bring structure, high standards, and a bit of backbone. People who’ll push back when something doesn’t make sense. The stack is Kotlin on AWS, but if you’ve used any OO language (Java, Python, Ruby, C#, PHP) and are open to learning, that’s fine. There’s a monolith (by design), organised into modules. They’re not obsessed with microservices for the sake of it. You’ll join a 20-person engineering team that’s currently levelling up its structure, introducing proper processes, and looking to hire another three backend devs this year. It’s remote first, with 90% of the team across Europe, and you’ll actually have autonomy to get work done. No legacy code. No over engineering. No ivory tower architects.
