Identify critical developer pain points and design platform solutions that remove barriers to productivity.
- Build & Scale AI-Native Development Platforms: Design and implement the Xero AI Engineering Toolkit and other AI-augmented development solutions that accelerate development velocity while maintaining code quality and security standards.
- Cross-Team Technical Leadership: Collaborate with product teams, infrastructure teams, and technical leadership across the organization to identify high-impact problems. Drive architectural decisions and implement solutions that benefit the entire engineering organization, operating across team boundaries without direct authority.
- Architect Unified Developer Toolchain: Consolidate fragmented tooling across Xero's engineering organization, reducing context switching and cognitive load. Design and implement integrated solutions that create seamless developer workflows.
- Balance Speed with Engineering Excellence: Develop and promote sustainability practices, implement Tech Health Scorecards, and establish metrics that ensure platform decisions prioritize long-term maintainability alongside delivery velocity.
- Mentor & Grow Technical Teams: Influence and mentor engineers and technical leaders through example and expertise rather than authority. Help teams develop their technical capabilities, discover their potential, and adopt best practices in platform engineering and developer tooling.
- Communicate Technical Vision to Leadership: Translate complex technical concepts, architectural decisions, and platform strategies into compelling narratives for senior stakeholders and executives. Influence organizational decisions through clear technical communication.
- Own Developer Feedback Loops: Establish tight feedback loops with the engineering community, gather telemetry on platform usage and satisfaction, and iterate platform solutions based on real developer needs and pain points.

## Full description
## **The role & impact**

As a Principal Engineer in our Engineering Productivity team, you'll partner with our engineering community to build frictionless, developer-first platform tools that remove barriers and empower engineers to focus on what they do best; shipping high-impact software faster, safer, and at scale. Your work directly shapes how thousands of engineers across Xero work, influencing the tools, practices, and cultures that enable them to succeed.

You'll tackle some of the most complex technical challenges across our organisation, from optimising developer workflows to scaling our AI-native development practices. In this role, you're not assigned to a single team; instead, you'll work across our engineering landscape to identify and solve the highest-impact problems - collaborating with multiple teams and stakeholders to drive meaningful change.

## **The team & how they connect**

Engineering Productivity is a specialist team within Xero's engineering organisation, focused on enabling our developer community through platforms and tooling. We collaborate closely with product teams, infrastructure teams, and technical leadership across the organisation to remove friction and accelerate delivery. Our team operates with high trust, psychological safety, and a genuine commitment to diverse perspectives - we believe the best solutions come from teams that think differently.

## **The team is currently working on**

* **Inner-Loop Mastery:** Supercharging local coding speed and developer experience through our Xero AI Engineering Toolkit
* **Frictionless Delivery:** Accelerating pull request reviews and environment provisioning to unblock our outer-loop development flow
* **Unified Tooling:** Consolidating our developer toolchain to eliminate context switching and cognitive load across our engineering teams
* **Uncompromising Quality:** Balancing speed with engineering excellence using Tech Health Scorecards and sustainable development practices

## **Where and how you can work**

This is a distributed role across Australia and New Zealand. Our teams are predominantly remote-first, with occasional in-person gatherings to strengthen connections and tackle complex problems together. We hold 1-2 on-site sessions per quarter (typically in Melbourne or Wellington/Auckland), and we maintain flexible working hours and arrangements to support your personal circumstances. We believe great technical work happens when people have autonomy over how and where they work.

## **Here are some of the things we are looking for**

* You bring demonstrated expertise in DevEx, DevOps, or Platform Engineering, with a proven track record of building products and platforms that engineers love to use
* You possess a platform-as-a-product mindset - you think deeply about your customers (engineers), understand their pain points, and design solutions that scale elegantly
* You're comfortable navigating ambiguous, rapidly evolving environments and can thrive when roadmaps shift and requirements remain fluid - you _Go Bold_ and _Go Fast_ even when the path isn't entirely clear
* Your communication skills enable you to influence and collaborate with senior technical stakeholders and executives across the organisation, translating complex technical concepts into compelling narratives
* You bring either exposure to or hands-on experience with AI-native development practices, spec-driven development, or modern AI development lifecycles that shape how we build tomorrow
* You mentor and grow others through influence and example rather than authority, helping engineers and teams level up and discover their potential

_Apply even if your experience isn't a perfect match! At Xero, we hire based on your skills, passion, and the unique perspective you can bring to enhance our culture and team._
