Job description

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

🚀Real Scale, Real Consequence - If you want your judgment to matter, this is the place. ROLLER is a global, rapidly scaling SaaS business backed by Insight Partners. In 2025, we powered 90 million guest experiences across those 35 countries and we’re growing fast towards 1 billion experiences a year. When things go wrong at this scale, the impact is real: lost revenue for operators and poor experiences for guests who are meant to be having fun, celebrating birthdays, or spending time with friends. The systems you design, build, and operate genuinely matter.

💻Real-World Complexity, Not Toy Problems - This role suits engineers who enjoy problems shaped by the real world. You’ll deal with jurisdictional differences, evolving regulations, and subtle edge cases where precision matters. Getting it right means venues run smoothly. Getting it wrong shows up immediately.

🧩System-Level Problems That Cut Across the Platform - You’ll work on high-impact capabilities like localisation, compliance, privacy, and regulatory requirements. These problems sit at the seams of the platform and require careful design across transactions, data, documents, and customer-facing flows. It’s work that demands system-level thinking, not just clean code.

🧠Depth Over Churn - Rather than bouncing between unrelated features, you’ll go deep on a clearly defined problem space. That depth rewards strong technical judgment, careful consideration of downstream impact, and a long-term view of quality.

Why You Want To Work With Us!

❤️Loved by Customers - ROLLER is consistently highly rated on Capterra and G2, and trusted by leading operators worldwide. Customer obsession isn’t a value on a wall here, it’s embedded in how we prioritise, build, and measure success.

🏆A Great Place People Choose to Stay - We’ve been Great Place to Work certified across multiple regions for several years running. That reflects a culture that values trust, autonomy, and growth, and an environment where high standards and psychological safety coexist.

💸Competitive Package & Real Career Growth - We offer competitive compensation and benefits aligned to the level of ownership we expect. As ROLLER scales, so do the opportunities. People grow here by taking on bigger problems, broader scope, and greater responsibility. Progression is driven by impact and capability, not tenure, and strong performance is recognised and rewarded.

About the Role

We’re hiring a Full‑Stack Software Engineer to join a London‑based squad focused on localisation and regional readiness as ROLLER expands across Europe.

You’ll build and ship changes across backend services, APIs, and customer‑facing workflows, often in integration‑heavy contexts. This squad works with high autonomy and will touch multiple areas of the platform, so you’ll need strong fundamentals, confidence in distributed systems, and a practical approach to delivery.

You’ll work in our ecosystem of applications, services, and infrastructure using a combination of C#, Angular/TypeScript, T‑SQL, and AWS (including Lambda, API Gateway, DynamoDB, S3, SES and SQS).

This role is based in London and offers a hybrid work approach, with our office located in Shoreditch, close to Liverpool Street.

What You'll Do

• Designing, building, and maintaining secure, scalable solutions across the stack.
• Enhancing the platform to support regional requirements and localisation needs across different markets.
• Building and maintaining APIs and services, including contributing to integration patterns with third‑party providers.
• Promoting quality through software craftsmanship, agile best practices and continuous delivery/deployment techniques.

About You

• Strong experience building and shipping full‑stack software in a modern SaaS environment.
• Experience with C# .NET (web APIs) and designing/consuming APIs in distributed systems.
• Exposure to integration work: third‑party systems, payments‑like workflows, compliance/regulatory domains or similarly complex ecosystems.
• Solid front‑end fundamentals (Angular/TypeScript).
• Comfortable with relational databases (SQL Server or similar).
• A self‑starter who finds practical solutions to challenging problems and enjoys simplifying complexity.
• Curious, collaborative, and comfortable working with teammates distributed across time zones.

🍼 16‑week paid parental leave for primary carers and 4‑week paid parental leave for secondary carers.

💙 Team Member Assistance Program to proactively support our team's health and well‑being – access to coaching, education modules, weekly webinars and more.

🧠 Work with a driven, fun, and switched‑on team that likes to raise the bar in all we do!

📚 Individual learning & development budget plus genuine career growth opportunities as we continue to expand!
