Software Engineer - Localisation

About ROLLER ROLLER isn’t your average SaaS company. We operate globally across 30+ countries, powering millions of real-world experiences in the leisure and attractions industry. What we build doesn’t just live on a screen. It shows up in busy venues, peak weekends, and unforgettable moments for guests. Our mission is simple but ambitious: help operators run better businesses while creating great guest experiences. That means solving complex, real-world problems across ticketing, point of sale, self-service, memberships, kiosks, and digital waivers, all at meaningful scale. Just as importantly, it’s the people. We’re a team of 300+ smart, grounded, and genuinely passionate humans working across the globe. We care about quality, ownership, and doing work we’re proud of, without taking ourselves too seriously. We’re growing fast, aiming high, and building something that matters. If you want to work on real problems, with real customers, alongside people who care deeply about their craft and impact, ROLLER is a great place to do it. Why You’ll Enjoy This Role! 🚀 Work that keeps venues trading - You’ll own fiscal and regulatory compliance across Europe. If it’s wrong, a venue can’t legally trade, so getting it right matters. 🤝 Your squad owns it - Squads are self-managing. The London squad owns localisation and compliance for Europe end to end, and you’ll work with your PM to decide what gets built, how it’s built and when it ships. 🌍 Real scale, real consequences - Thousands of requests per second across hundreds of containers, powering over 100 million guest experiences in 2025 alone. ✨ Help shape a growing team - Be one of the first engineers in London, set how the squad works, and help new engineers get up to speed. Why This Role Matters ROLLER is growing fast across Europe, and every new market brings its own rules on tax, invoicing, receipts and language. Our London squad makes sure venues in those markets can trade legally and run in their own language. Recent work includes fiscal compliance for markets like France, Germany and Austria, and AI-assisted translations across the platform. You’ll join a small London squad reporting to a London based Tech Lead. Our HQ is in Australia, so most of your work with the wider team is async, with live time together every week or two. You’ll be comfortable owning your work, unblocking yourself and finding your own ways to stay connected. Our backend runs on C#, .NET, T-SQL and AWS services including Lambda, API Gateway, DynamoDB, S3, SES and SQS. On the front end, we use Angular alongside our own design system and component library. What You’ll Do Build Design, build and ship changes across backend services, APIs and the Angular interfaces venues use every day Build patterns for regional rules and compliance that we can extend to new markets Own integrations Lead integration-heavy work with third-party providers, like fiscal and certification partners: define the contract, handle the edge cases and plan for failure Work directly with those providers when something needs chasing or clarifying Own production Collaborate closely with the SRE team to monitor system performance and proactively identify potential issues Triage compliance alerts and fix the root cause Raise the bar Share what you know through code reviews, pairing and honest feedback Work with your PM to break vague regulatory requirements into small, shippable pieces About You You have a high appetite for Technology and AI and a natural curiosity for how it can transform your work.
