Senior Machine Learning Engineer

Working at Atlassian

Atlassians can choose where they work – whether in an office, from home, or a combination of the two. That way, Atlassians have more control over supporting their family, personal goals, and other priorities. We can hire people in any country where we have a legal entity.

Responsibilities

The Central AI org is part of the larger Atlassian Intelligence program. Its purpose is to accelerate AI innovation across all our products and platform, provide cohesive AI experiences and set up an Atlassian AI infrastructure for the future. While it is 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 seamless integration and optimal functionality of AI across various departments. By doing so, Central AI ensures that different teams within the organization 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.

As a Senior Machine Learning engineer, you will work on the development and implementation of cutting‑edge machine learning algorithms, training sophisticated models, collaborating with product, engineering, and analytics teams to build AI functionalities into each Atlassian product and service. Your daily responsibilities will encompass a broad spectrum of tasks such as designing system and model architectures, conducting rigorous experimentation and model evaluations, and providing guidance to junior ML engineers.

Your role is pivotal, stretching beyond these tasks, ensuring AI’s transformative potential is realized across our offerings.
