Over the past 30 years, we’ve grown from humble beginnings with a single computer to a global technology company (ASX-300 listed company, JIN). Partnering with over 15,000 good causes worldwide and helping raise more than $260 million last financial year. Innovation isn’t just part of what we do; it’s who we are.

We develop cutting-edge solutions empowering our lottery and not-for-profit partners to raise funds for their vital causes. We believe in fostering an environment where talented people can innovate, grow, and have fun.

What will you be doing?

You'll join a cross-functional engineering team (5–6 people) working on core platforms that power Jumbo's customer experience, admin tools, and APIs. You'll design, build and improve backend services in PHP and Go across our established core platform and growing microservices ecosystem.

You'll own features end-to-end: from solution design through implementation, testing and deployment. You'll enhance system performance and observability, manage service integrations including Kafka-based messaging and internal APIs, and contribute to technical decisions that keep our platform robust and modern.

What Your Day-to-Day Will Look Like

• Design, build and maintain robust backend services in PHP and Go across our microservices ecosystem (Docker, Postgres, Kafka) for customer-facing platforms and internal admin systems

• Own features end-to-end: from technical discovery and solution design through implementation, automated testing, deployment and ongoing support

• Collaborate closely in a cross-functional squad (backend, frontend, QA, product) to refine requirements and deliver high-quality outcomes

• Contribute to the architecture and evolution of our platforms, planning new services and improving system integration and communication

• Proactively improve system performance, reliability and observability through monitoring, tuning and technical debt reduction

• Participate in code reviews (Gerrit) and CI/CD workflows (Jenkins), using AI-assisted tools where appropriate to maintain engineering standards

• Balance product feature work with BAU tasks (production issues, platform improvements)

• Share knowledge with teammates, mentor less-experienced engineers and produce clear, accurate documentation

• Manage time effectively, prioritise tasks and accurately estimate project timelines

What You’ll Be Able to Bring to the Role

• Strong backend engineering experience with complex, high-traffic or mission-critical systems

• Deep expertise in PHP or Go, with exposure or willingness to upskill in the other

• Solid understanding of microservices architectures, distributed systems and how services communicate at scale

• Hands-on experience with modern backend tooling and practices: CI/CD, automated testing, Docker, Postgres, Kafka and code review/build pipelines

• Ability to design, plan and implement services, with experience or interest in tech lead/architectural decision-making

• Experience working in cross-functional product teams, collaborating with front-end engineers, QAs and product managers

• A pragmatic mindset for balancing product work with BAU, platform improvements and scaling/monitoring initiatives

• Curiosity and practical experience with AI-powered engineering tools, and an understanding of how they enhance your workflow

• Strong problem-solving skills and ability to navigate and improve mature codebases with a mix of monoliths and microservices

• Clear communication skills, collaborative approach and comfort working within established engineering standards and processes
