Senior .NET Engineer | Greenfield Platform | AI-Native Engineering

Location: Melbourne (hybrid, versatile)

Our client is an established Australian payments business, issuing cards and running payment programs for large organisations and government. They’re building a new global, cloud-first platform that will eventually replace their existing systems. Australia is next to go live, starting with a brand-new product launching here first.

This role is the first hire in a new Melbourne engineering team building on that platform.

What you’ll be doing

- Building out the new platform for the Australian market in C# / .NET on Azure
- Turning architecture requirements into strong, well-thought-through designs, and leading the technical build
- Working closely with the global platform team based in the UK
- Using AI-led engineering every day. The team runs its development process with AI agents (BMAD), and you’ll help other engineers adopt the same practices
- Helping shape how the Melbourne team works as it grows

Tech environment

C# / .NET • SQL Server • Azure (AKS, containers,



Service Bus) • Redis

What they’re looking for

- Strong senior backend experience in C# / .NET
- Commercial cloud experience: Azure preferred, AWS is fine
- Hands-on experience with an AI-led development framework (BMAD, OpenSpec or similar), or a clear track record of investing serious time in it
- Comfortable working independently and with a team in another time zone. This includes some evening calls, with flexibility around your hours
- Happy to pick up some front-end work when needed
- Payments or fintech experience is a bonus, not a requirement

Why join?

- Greenfield, cloud-first, AI-native from day one
- A genuinely hard technical problem: moving several live platforms onto one
- Early influence as one of the first engineers in a new team
- An experienced leadership team that has built and scaled a payments business before
- Flexible hybrid: up to two days a week in the Melbourne office
