Xero is seeking a Senior Software Engineer to lead the delivery of high-impact, customer-focused software solutions for their practice tools platform. You will navigate complex, open-ended problems with strong technical depth and operational insight, driving cross-team initiatives and building alignment across disciplines to influence engineering direction. You will join a collaborative engineering community dedicated to helping small businesses access enterprise-grade technology. Working closely with Lead and Principal Engineers, the team applies modern software delivery frameworks to improve system performance, reliability, and developer efficiency while championing agile practices. Initially, you will focus on building full-stack features using React, Redux, C#, ASP.NET Core, and SQL Server; refactoring complex monolithic systems that balance legacy WebForms with modern distributed architectures on AWS; researching and adopting AI-assisted development tools to reimagine engineering workflows; and participating in on-call rosters to ensure 24/7 product support and reliability. You bring deep technical expertise across C#, ASP.NET Core, modern frontend frameworks like React, and SQL Server data modeling. You have proven experience building and implementing AI tools into production environments with measurable business impact. Your background includes architecture, implementation, and refactoring of distributed systems using REST APIs on AWS, solid CI/CD experience, and a passion for test-driven development. You treat AI as a tool to redesign workflows and create automated agents rather than just a productivity add-on. Experience building SDKs and internal libraries that enable team integration is highly valued. You mentor and coach inclusively, with a challenger voice comfortable disagreeing early to help design better systems. Xero offers a flexible hybrid working environment across Sydney, Melbourne, Canberra, or Brisbane, with designated team boost days for in-person collaboration and occasional travel to Melbourne as required.
