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, developing, and optimising native iOS applications that power engaging lottery and fundraising experiences. You'll work across the full mobile app lifecycle – from shaping solutions and building new features, through to testing, release, and ongoing improvements – always with a focus on intuitive, high‑performance user experiences that align with iOS guidelines and make the most of device capabilities.
You’ll collaborate closely with other engineers, quality specialists, and product managers to deliver reliable, scalable apps that support our global partners and their vital causes. Depending on your experience, you’ll take ownership of features or projects, contribute to architectural decisions, and have opportunities to mentor more junior developers as we evolve and grow our mobile platforms.
What Your Day-to-Day Will Look Like

Based in Brisbane and working out of our Head Office, our hybrid working model combines in-office collaboration (three days per week) with WFH work (two days per week).
