The opportunity

We're partnering with a leading Australian financial services organisation on a major engineering program: building a next-generation cloud platform from the ground up. It's a large-scale re-architecture that will underpin the organisations AI and digital ambitions for years to come.

What you'll do

- Build and evolve high-performance services and APIs in modern C# and .NET
- Design and deliver cloud infrastructure as code with Terraform , including reusable modules for other teams to adopt
- Architect and build solutions across AWS compute, networking and data services
- Take full ownership of what you build, from design through to production
- Ramp up quickly and contribute from day one
- Help shape the platform's architecture, engineering standards and performance
- Make AI tools a core part of how you analyse problems and write code

What you'll bring

- Extensive commercial experience with C# and .NET Core ,



including APIs and microservices
- Robust hands-on Terraform experience, ideally including building and versioning reusable modules
- Broad, practical AWS knowledge across networking, IAM, compute, data and security
- Experience designing and building CI/CD pipelines, not just using them
- A strong grounding in software design principles such as SOLID and Clean Architecture
- Solid experience with relational or document databases (e.g. Postgres, Aurora, SQL Server)
- A proven track record of taking complex systems from concept to production
- The ability to turn high-level requirements into well-designed, working solutions with minimal guidance

Nice to have

- Amazon Bedrock or production GenAI/agentic experience
- AWS data and streaming services (e.g. Athena, Glue, Kinesis)
- Scripting in Python, Bash or PowerShell
- Observability tooling (e.g. Grafana, Prometheus)
