Over 30 years, we've grown from humble beginnings (founded 1995) to a global digital lottery technology leader (ASX: JIN), operating in Australia, the UK, Canada and the USA. We partner with thousands of good causes worldwide, helping raise over $290M in FY25 alone. Innovation is at the heart of everything we do.

Our Growth – And It's By Design

Following a series of significant client wins and the expansion of our business through international acquisitions, we're in an exciting phase of growth. To support this momentum, we're scaling our engineering capability and building out our teams to meet increasing demand across our platforms and products.

This growth is driven by a deliberate investment ahead of demand as we support a larger, more complex, and increasingly global business. We're expanding our teams to continue delivering high-quality, scalable solutions.

For engineers joining us, this is a chance to work on meaningful problems at scale—from supporting new clients and markets, to integrating and evolving acquired platforms, to helping shape how our platform will grow over time. You'll be joining a business with real momentum, plenty of opportunity to make an impact, and the chance to grow alongside it.

What will you be doing?

You’ll design, build, and optimise the server-side components that power our lottery and not-for-profit solutions. You’ll work on robust, scalable systems, data storage, and APIs that enable seamless, high-performance user experiences and support our partners in raising funds for vital causes.

Working closely with other engineers, quality analysts and product managers, you'll solve complex technical problems and continuously refine our platforms.

• Contribute to system architecture discussions.

What You’ll Be Able to Bring to the Role

• Proven experience in server-side programming and/or scripting languages, with a focus on building scalable back-end services
• Strong understanding of data structures, databases, and designing performant data storage solutions
• Experience designing, building, and optimising APIs that power user-facing applications
• Ability to optimise existing systems for performance, reliability, and scalability
• Comfortable working across multiple software languages, tools, and technologies, or eager to broaden your stack
• Solid grasp of software engineering best practices, including testing, code reviews, and documentation
• Effective time management skills, with the ability to prioritise work, estimate effort, and meet agreed timelines
• Clear and confident communicator who can collaborate closely with engineers, quality analysts, and product managers
