Principal Engineer

A day in the life

• Shape the technical direction across multiple engineering teams, helping ensure what gets built is scalable, maintainable, and aligned to where the business is heading
• Partner closely with Product Managers to explore ideas, challenge assumptions, and turn complex problems into practical, high-quality solutions
• Lead architecture and design discussions, setting the bar for how systems are designed and decisions are documented
• Spend time with engineers across teams in mentoring, unblocking, and sharing patterns that improve how work gets done
• Champion reliability and operational excellence by guiding teams on observability, system performance, and learning from incidents
• Bring a strong engineering voice into broader conversations, influencing not just how things are built, but what we build and why
• Collaborate across Engineering, Product, and Architecture to connect technical decisions to real customer and business outcomes

About the role

This role exists to provide senior technical leadership across PEXA’s engineering landscape, shaping both the technical direction and the product outcomes we deliver. You’ll act as a trusted advisor across teams, influencing decisions through expertise, not authority, and helping raise the overall engineering bar.

We are hiring for a number of Principal Engineers across the application and platform engineering space. Candidates with strong specialisations in modern application development, infrastructure automation or bringing API first thinking to life will be top contenders.

Key capabilities for success:

What success looks like (6–12 months):

• You’ve established trust across engineering and product teams as a go-to technical leader
• Clear, consistent architecture patterns and standards are being adopted across squads
• Engineering is influencing product direction earlier, with better alignment between technical and business outcomes
• Reliability, observability, and operational thinking are visibly improving across systems
• Engineers are growing through your mentorship, and communities of practice are actively sharing knowledge
• You’ve helped uplift hiring and assessment standards, contributing to stronger technical capability across the organisation
