Principal Engineer - Search

provide cohesive AI experiences and setup up an Atlassian AI infrastructure for the future.

While it's anticipated that the majority of AI-driven initiatives will be developed and executed by federated product teams within Atlassian, the role of Central AI is pivotal to this process. Central AI is tasked with constructing the underlying infrastructure and capacities, which are crucial for the seamless integration and optimal functionality of AI across various departments. By doing so, Central AI ensures that different teams within the organisation do not work in silos but have access to a unified foundation that promotes efficiency and collaboration. Additionally, Central AI is responsible for developing some of the core shared experiences typical in the AI domain, such as search, knowledge discovery and conversation.

What you'll do:

• Pioneer the development of search relevance capabilities to meet the needs of the AI wave

• Drive large, complex projects autonomously, from technical design to launch

• Contribute to ongoing feature development, specialising in search functionality and be the domain expert on search and relevance related technologies

• Solve architecture challenges, apply architectural standards and start using them on new projects

• Lead code reviews & documentation as well as take on complex bug fixes, especially on high-risk problems

• Strong expertise in Java or equivalent language technology and the ability to write performant production-quality code

• Experience building and scaling machine learning models in business applications using large amounts of data

• Focus on business practicality and the 80/20 rule; very high bar for output quality, but recognise the business benefit of "having something now" vs "perfection sometime in the future"
