Perth, WA

6-12+ Months Contract

Build software that runs real mining operations. See your work live on an open pit mine site.

We are looking for a Senior Full Stack Developer or solid Backend Developer to help build and evolve a large scale software platform used in open pit mining operations.

This is not internal tooling or maintenance work. You will be building new features in a modern, distributed system where the changes you make are deployed into live mine sites and used every day by operational teams.

If you care about ownership, clean architecture, and seeing your work have real world impact, this role is worth a look.

What you will be working on

You will join a cross functional product squad responsible for delivering new capabilities across a complex operational platform that supports fleet and equipment workflows in open pit mining.

Your work will include:

- Designing and building backend services using C# and .NET in a microservices and event driven architecture
- Building modern React applications focused on clarity, performance, and usability
- Owning features end to end from design through to production deployment




- Working closely with domain experts to turn complex operational problems into reliable software
- Contributing to architectural decisions, technical standards, and engineering best practice
- Improving reliability, observability, and performance in a mission critical system

What we are looking for

Backend

- Strong experience with C# and .NET
- Experience designing and building microservices and event driven systems
- Solid SQL skills and experience with SQL Server
- Experience with Entity Framework or similar ORMs
- Comfortable owning APIs, service design, and data models

Frontend

- Strong experience with React
- Experience using modern component libraries such as MUI, Mantine, or shadcn
- Experience with state management libraries such as Redux, Zustand, or MobX
- A focus on building maintainable and user friendly interfaces

Nice to have, not required

- Docker and Kubernetes exposure
- Experience integrating with native or performance critical systems such as C++
- Previous experience in mining or industrial software
- Experience working with open pit mining systems

We are primarily looking for strong engineers. Mining experience is advantageous but not essential.
