Senior Software Engineer

We’re building a better way for retailers to grow customers, not just reward them.
At Slyp, our end-to-end platform combines loyalty, payments and transaction intelligence to help retailers understand how their customers shop, identify where growth exists and turn those insights into automated action with measurable results.
Through Go Rewards, our consumer app and merchant loyalty platform, we connect shoppers with personalised offers and rewards while giving retailers deeper insights into their customers.
Our technology has been used across Australian retail by brands including Kmart, Chemist Warehouse, JD Sports, Country Road Group, Harris Farm, Supabarn and SPAR. We’ve processed billions of transactions and analysed over 15 billion products sold, giving us a unique view of customer, category, basket and promotional behaviour.
Now we’re building on that foundation to move loyalty beyond points and discounts. Using AI, payments and SKU-level data, we’re helping retailers identify each customer’s growth potential, personalise the right action and measure whether it actually changed behaviour.
 
Why Slyp?
Founded by former PayPal executives, Slyp offers an inclusive environment where Slypsters can unleash their creativity and drive while being part of a movement that's shaking things up for the better. This is a high-impact role in a fast-growing company with real-world reach. You'll have autonomy, ownership and direct access to leadership, working with a fun, supportive team that's passionate about what we're building.
The Role
We're looking for an exceptional, hands-on Senior Software Engineer who is passionate about building great software and exploring what's possible with AI.
You'll design and ship production software across our loyalty and rewards platforms, develop new AI-powered product capabilities, and help accelerate our engineering team's adoption of agentic development workflows.
This is first and foremost a software engineering role. You'll work closely with our CTO and experienced engineers, taking ownership of complex technical challenges while bringing practical experience with AI coding agents, automation and modern development practices.
We're looking for someone who leads by building: experimenting with new approaches, demonstrating what works and helping turn successful ideas into repeatable engineering practices. You'll have a genuine opportunity to influence how we build software as we evolve our AI-native product development.
This is a full-time, hybrid role based in Sydney, with direct access to leadership and significant technical ownership.
