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 play a key role in designing, building, and optimising the user interfaces that power our lottery and fundraising platforms. You'll translate UX/UI designs into high-quality, performant, and accessible front-end experiences that work seamlessly across modern browsers and devices, helping our partners raise more funds for good causes around the world.

You'll be hands-on in the codebase, collaborating with engineers, product managers and quality analysts to deliver new features, refine existing functionality, and continuously improve the look, feel, and responsiveness of our applications.

What Your Day-to-Day Will Look Like

• Design, develop, test, and maintain high-quality front-end features and user interfaces for our lottery and fundraising products.

• Translate UI/UX designs and mockups into clean, maintainable, and accessible code.

• Optimise existing front-end components for performance, scalability, and responsiveness across devices and browsers.

• Participate in meaningful code reviews, front-end testing, and quality assurance activities to ensure robust, reliable releases.

• Work within a fast-paced continuous delivery environment, contributing to frequent releases and owning your changes from build through deployment and ongoing maintenance

• Collaborate closely with Software Engineers, Product Managers, and Quality Assistance Analysts to refine requirements and deliver value incrementally.

• Contribute to UI/UX decisions, providing input on usability, accessibility, and interaction design.

• Accurately estimate work, manage your time effectively, and deliver tasks within agreed timelines.

• Produce clear and timely technical documentation for features, components, and processes.

• Continuously improve front-end standards and best practices.

What You’ll Be Able to Bring to the Role

• Experience designing and developing user interfaces for complex software applications, with a strong focus on usability and intuitive user experiences

• Proficiency in front-end development using modern programming and/or scripting languages and frameworks aligned to UI engineering, with a strong focus on React and TypeScript (e.g. React with TypeScript and other contemporary UI libraries or frameworks)

• Solid understanding of responsive, accessible, and performant front-end design across different devices, platforms, and browsers

• Ability to translate UI/UX design mockups and interaction patterns into high-quality, maintainable code

• Experience writing clean, well-structured, and testable code, following engineering standards and best practices

• Experience with modern front-end testing frameworks (e.g. Jest, React Testing Library, Cypress) and a pragmatic approach to deciding what to test and how to balance speed versus thoroughness

• Strong problem-solving skills and attention to detail, with the ability to debug and optimise for performance and scalability

• Comfortable working both independently and as part of a cross-functional team with engineers, product managers and quality specialists

• Effective time management skills, including the ability to prioritise tasks and provide realistic estimates for work

• Clear and constructive communication skills, including participation in code reviews and producing accurate technical documentation

• A collaborative mindset and willingness to share knowledge.
