Responsibilities
Search Platform’s mission is to power world-class, trusted cross-product knowledge search and discovery for people and agents across all of Atlassian’s product and agentic surfaces. We are looking for a product-minded ML systems leader with deep expertise in applied machine learning and production ML infrastructure. As a Principal Machine Learning Systems Engineer, you will push the boundaries of how ML powers document understanding, content representations and indexing for enterprise and agentic search. You will own a major capability from problem framing and experimentation through architecture, launch, operation and continuous improvement.
Responsibilities
Set the technical direction for a major ML-powered Search Data and indexing capability, translating customer and product problems into ambitious, measurable ML and systems outcomes.
Advance and productionise ML approaches for document understanding, enrichment, embeddings and semantic representations, index construction and index evolution.
Own the ML lifecycle end to end: data and feature strategy, model selection, adaptation or training, deployment, offline evaluation, monitoring and continuous improvement. Partner with Search Quality and product teams on online outcome measurement.
Design scalable ML and distributed-data systems that operate across heterogeneous sources while balancing retrieval quality, freshness, correctness, reliability, latency and cost.
Create reusable ML and indexing patterns that make content from new sources and content types easier to represent and index with strong default search quality.
Lead difficult technical decisions across partner teams and advance the ML and engineering craft of the group through hands-on work, mentoring and clear communication.
Qualifications
At Atlassian, we strive to design equitable, explainable, and competitive compensation programs. We follow consistent hiring practices and account for each candidate's skills, knowledge, and experience when setting base pay within the range. This role may also be eligible for

, bonuses, commissions, and equity.
Requirements
10+ years of hands-on experience building models or production ML systems, with deep applied-ML experience in areas such as search, information retrieval, recommendation, NLP, LLMs or content understanding.
Proven experience designing, building and operating production ML systems across data preparation, representations or features, model development, deployment, evaluation, observability and model or data drift.
Strong software, distributed-systems and data-engineering depth, including large-scale processing, indexing, failure recovery, schema evolution, scalability and cost.
A track record of technical innovation: evaluating new research or industry techniques, proving their value through rigorous experiments and turning successful ideas into reliable production capabilities.
Strong product judgment: ability to discover the real customer problem, define measurable outcomes and choose appropriately among rules, classical ML, deep learning and LLM-based approaches.
Experience leading across ambiguous, multi-team initiatives, including setting direction, influencing senior engineers and developing other technical leaders.
