Brisbane, Queensland, Australia BLACKROC Full time $120,000 - $200,000 per year

About the Company

We're a mining software company that started in Australia and now operates globally. Our tools help miners plan, optimise, and run more sustainably. The challenges are complex - from underground scheduling to emissions tracking - and the solutions we build genuinely change how the industry works.

The Role - Principal Software Engineer

We're looking for a senior engineer who still enjoys coding but also knows how to guide architecture, influence technical decisions, and mentor others. You'll be working across large-scale applications used worldwide, balancing new greenfield builds with the ongoing evolution of long-standing platforms.

What You'll Do

  • Design and deliver secure, scalable applications that support mining operations globally.
  • Stay hands-on with code while setting standards for architecture, testing, and documentation.
  • Work across both Java and .NET systems - many of our newer services are Java-based, while key modules with long customer history remain in .NET. Both are critical, and we're steadily modernising and integrating them through APIs and cloud services.
  • Help shape technology direction across cloud-native platforms, DevSecOps, and automation.
  • Collaborate with product managers, mining specialists, and customers to ensure outcomes line up with operational needs.
  • Mentor engineers, encourage knowledge sharing, and lift the technical bar across the team.

Tech Stack

  • Core: Java 21, React/TypeScript, Playwright, MCP.
  • Microsoft stack: .NET 8, C#, ASP.NET Core, Power BI, Azure SQL, Azure Functions, Service Bus, Azure DevOps.
  • Cloud & Ops: AWS + Azure, Kubernetes, CI/CD, observability.
  • Mining / Sustainability Focus: Optimisation algorithms, AI/ML for emissions modelling, IoT for equipment telemetry, blockchain pilots for carbon credit tracking.

What We're Looking For

  • Strong coding background with the ability to move between Java and .NET.
  • A pragmatic engineer who values working software over red tape.
  • Curious, hands-on, and capable of tackling both architecture and implementation.
  • Interested in building software that helps an industry move toward safer, more efficient, and lower-emission operations.
