Full Description

Overview 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 Search Quality Definition & Evaluation Define and track core retrieval metrics (Hit@K, Precision, Recall) to objectively measure the effectiveness of the search tool across different internal datasets. Collaborate with domain experts to curate "Golden Datasets" (Ground Truth) to benchmark passage ranking and chunking strategies against real-world agent queries. Develop automated regression suites that flag degradation in retrieval quality before code reaches production. Latency Optimization & High-Scale Engineering Optimize the retrieval path to ensure low-latency responses, critical for multi-step agent chains where search creates compounding delays. Operational Excellence & Quality "Dissat" Response Serve as the primary on-call engineer for "Search Dissatisfaction" (Dissat), investigating instances where agents failed tasks due to poor information retrieval. Perform root cause analysis on bad queries to determine if the fix requires re-indexing, better chunking logic, or updated embedding models. Monitor system health and search saturation, proactively scaling infrastructure to handle bursty workloads from concurrent agents. Qualifications Compensation At Atlassian, we strive to design equitable, explainable, and competitive compensation programs. To support this goal, the baseline of our range is higher than that of the typical market range, but in turn we expect to hire most candidates near this baseline. Base pay within the range is ultimately determined by a candidate's skills, expertise, or experience. In the United States, we have three geographic pay zones. For this role, our current base pay ranges for new hires in each zone are: This role may also be eligible for benefits, bonuses, commissions, and equity. Please visit go.atlassian.com/payzones for more information on which locations are included in each of our geographic pay zones. However, please confirm the zone for your specific location with your recruiter.
