The team / how they connect

You will join the AI Products group, a diverse, globally distributed team of scientists, engineers, product managers, and analysts within our broader Data & Science division. Machine Learning Engineers partner closely with Applied Scientists during the research phase to build interfaces and harnesses that safely transition models from research to production. Together, this collaborative team reduces toil and delivers beautiful, data-driven insights for small businesses.

The team is currently working on

  • Refactoring complex systems and designing highly scalable, distributed production infrastructure to support next-generation AI features
  • Harnessing Python, SQL, and distributed processing engines such as Spark or Dask to handle web-scale data workloads
  • Developing production environments utilizing established AI frameworks, data orchestration tools like Airflow or Prefect, and managing cloud workloads via AWS EMR
  • Exploring and applying modern Large Language Model technologies to drive continuous product innovation

Where and how you can work

Xero offers a flexible hybrid working model designed to blend the collaboration of office life with the autonomy of remote work. You will have access to our modern office spaces, with expectations around office days and collaborative 'boost days' aligned to help your team connect and ship great code effectively.

Here are some of the things we are looking for

  • You will bring excellent system design and coding proficiency in Python or alternative languages suited for web-scale AI applications
  • A deep understanding of distributed processing principles alongside strong SQL capabilities is essential for success
  • Your exceptional communication skills enable you to easily translate complex technical concepts for both business and technical audiences
  • Having a natural coaching mindset will allow you to successfully establish engineering standards and mentor junior machine learning colleagues
  • An eagerness to learn, master, and implement Large Language Model technologies into product features
  • Experience utilizing frameworks like MLFlow, TensorFlow, or PyTorch, combined with knowledge of data orchestration tools, will be highly valued

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.
