The Role

The role & impact

As a Senior Software Engineer, you will be a hands-on contributor building and managing software that solves complex engineering problems at scale. You will apply your expertise to develop high-quality, scalable software while refactoring monolithic systems into resilient, distributed components.

Your impact extends beyond code as you act as a mentor and role model, championing technical excellence and contributing to engineering standards. By automating manual processes and assessing production issues, you ensure the delivery of seamless experiences for our customers.

The team & how they connect

The team helps small businesses get paid faster by simplifying the process of accepting online payments. We specialise in optimising onboarding flows and running targeted experiments to ensure users can effortlessly discover, evaluate, and sign up for our payment solutions. The team is deeply data-driven with a strong customer-first mindset, working collaboratively across Product, Design, and Engineering to deliver beautiful software.

The team is currently working on

  • Modernising architecture by transitioning monolithic systems into scalable, distributed microservices.

  • Evolving our tech stack, which primarily includes C#, .NET, AWS, and Kubernetes, while maintaining a React-based frontend.

  • Enhancing product innovation through the integration of AI tools and automated delivery practices.

  • Strengthening our internal engineering ecosystem by building shared libraries and SDKs to support wider integration.

Where and how you can work

This role is available in Melbourne, with hybrid work arrangements.

Here are some of the things we are looking for

  • You will bring strong experience in full-stack development with modern technology stacks, demonstrating proficiency in a range of languages and tools, and a high degree of openness to learn new technologies. Experience in our core stack - which often uses a microservice written in C# on .NET, utilising AWS services, running in a Docker container orchestrated by Kubernetes, and accessed by a SPA written in React with TypeScript will be highly valuable.

  • You have high proficiency in the architecture and implementation of distributed systems.

  • You can demonstrate a deep understanding of the full development lifecycle, including design, implementation, testing, and deployment.

  • You are proficient with CI/CD concepts and tooling, as well as on-call practices for proactively managing production systems.

  • You have proven your ability to mentor and coach engineers, fostering growth and effectively collaborating in a cross-functional team environment.

  • You bring experience contributing to internal ecosystems by building SDKs and libraries to enable other teams to integrate with your products.

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.
