About The Role
Ready to set the technical agenda for engineering at scale? At Bunnings, we're embedding modern platforms, automation, and AI capabilities at the heart of our business, and we are seeking a principal-level leader to shape the next era.

As a Principal Engineer, you'll operate as both architect and hands-on technical leader, guiding our most significant digital, platform, and emerging technology initiatives from inception to impact.

What's Involved

• Define and own technical strategy for key platforms and systems, balancing speed, quality, and maintainability.
• Lead end-to-end design and delivery of business-critical solutions, from conceptual architecture to production deployment and continuous improvement.
• Partner with product, engineering, and business leaders to shape our technology roadmap and delivery programs.
• Provide deep technical leadership and mentorship, uplifting engineering and architecture capability across teams.
• Drive best practice in architecture, secure software development, testing, and DevOps, including cloud-native design (Azure/AWS) and CI/CD automation.
• Stay ahead of emerging technologies—including cloud, automation, data platforms, and AI/GenAI and apply them pragmatically where they unlock value.
• Lead technical governance, architectural reviews, and proactive management of technical debt.
• Champion a culture of experimentation, knowledge sharing, and pragmatic engineering.
• Influence recruitment, onboarding, and professional development across the technical community.

Who We're Looking For
You are a technical strategist and hands-on leader with the confidence to drive large-scale transformation. You thrive in ambiguity and enjoy solving deep technical challenges that unlock business value. You communicate with impact, whether you're engaging an engineering squad, a senior executive, or a cross-functional working group.

You Demonstrate

• Depth in software and platform engineering, with the ability to shape system architecture, platform strategy, and delivery at scale.
• Strong hands-on experience across core programming languages (e.g., Python, C#, or Java) and frameworks.
• Expertise in architecting cloud-native, distributed systems and microservices (preferably Azure, with AWS/GCP as a plus).
• A strong grasp of SDLC, Agile, and DevOps, and the ability to elevate engineering discipline in others.
• The ability to mentor, coach, and develop senior engineers and architects, creating a high-performance, high-trust culture.
• A passion for learning, with an interest in emerging technologies such as automation platforms, AI/GenAI, orchestration tools, and enterprise data systems.

You'll Need

• Significant experience (ideally 10+ years) in software engineering, with a strong track record of technical leadership in complex digital environments.
• Demonstrated experience architecting and delivering high-value solutions in areas such as platforms, automation, or AI-driven systems.
• Deep hands-on experience with modern cloud environments, microservices, and CI/CD automation.
• Proven ability to influence technical direction and business outcomes at scale.
• Bachelor's or Master's degree in Computer Science, Engineering, or a related field (or equivalent experience).

You'll be part of a workplace where you'll feel like you belong.
