The next step in your career starts here…

If you're a hands-on technical leader who thrives on solving complex problems, shaping technology strategy, and mentoring talented engineers — this is your opportunity to make a lasting impact.

As our Principal Engineer, you'll sit at the intersection of technology and strategy — designing and delivering scalable, future-ready solutions that drive our business forward. You'll set the standard for engineering excellence, leading by example through deep technical contribution, thoughtful architecture, and a passion for innovation.

What you'll be doing

No two days are the same — you'll have the opportunity to:

• Design, build and deliver complex systems and platforms that are robust, elegant, and maintainable.
• Partner with the GM of Engineering & Innovation to define and champion architectural principles that scale with our business.
• Guide engineering teams through technical challenges, code reviews, and solution design — elevating capability and confidence.
• Work closely with product owners, GMs, and stakeholders to align technical solutions with business goals and user needs.
• Drive the evolution of our systems — from decoupled, componentized architectures to simplified user experiences and cleaner back-end services.
• Ensure our solutions meet architectural standards and governance while promoting CI/CD, DevOps, and quality-first delivery.
• Explore new technologies, tools, and trends — and bring forward ideas that help us continuously innovate.

What you'll bring

• 5+ years in a senior engineering or technical leadership role
• Proven experience delivering large-scale software solutions using the .NET stack (C#, ASP.NET Core, Entity Framework, Web APIs)
• Strong background in cloud platforms (Microsoft Azure preferred) and modern DevOps practices
• Deep understanding of architecture principles, governance, and scalable design
• Experience applying domain-driven design and building cloud-native solutions
• Strong communication and stakeholder management skills — equally comfortable in strategy sessions and code reviews
• A passion for mentoring, developing others, and fostering engineering excellence
• Subject matter expertise in one or more areas: Application Architecture, Integration, Data, Infrastructure, or Security
• A relevant degree in Computer Science, Engineering, or similar

What you'll get in return

We provide our team with a wide range of perks and benefits, including:

• Development and career progression pathways
• Access to our employee discounts, benefits and wellbeing program
• Purchased additional leave program
• Novated leasing and salary sacrifice
• 12 weeks Paid Parental Leave in addition to government parental leave scheme
