Senior Principal Engineer, Search Platform

Role Description

As a Senior Principal Engineer in Search Platform, you will own technical roadmap, execution and outcomes for the Search Data pillar. You will help envision, build and evolve a cutting-edge platform for integrating, processing, indexing and searching massive volumes of unstructured data across 100+ sources. Your deep expertise in large-scale data platforms, streaming and batch processing and distributed systems will help solve complex problems including infrastructure, data and dev/agentic productivity challenges.

Responsibilities:

• Collaborate with technical leads, partner teams and internal customers to define technical strategy and architecture for Search Data.
• Lead the evolution of our data platform and pipelines to meet the demands of both real-time search freshness and AI/agentic retrieval at enterprise scale.
• Make hard architectural trade-offs between freshness, correctness, cost, and operational simplicity - and own the outcomes.
• Drive the simplification and modernization of complex, legacy data processing systems. Identify and eliminate unnecessary complexity.
• Establish design patterns and best practices for handling the inherent messiness of real-world data - schema evolution, partial failures, eventual consistency, connector variability, and data quality degradation.
• Own engineering and operational excellence for the health of our systems and processes. Proactively drive opportunities for continuous improvements and own key operational metrics.
• Transform developer productivity to ensure that we unleash the potential of our own team with agents. Champion a culture of high ownership, rigorous testing, safe rollouts, and data-driven engineering across Search Data teams.
• Help hire and mentor engineers to build an open, innovative and operationally responsible culture.

Qualifications

• Deep experience with distributed data frameworks (Kafka, Flink, Spark) - you have built, operated, and debugged systems processing billions of events per day, ideally for Search and AI use cases.
• Strong background in designing data architectures that handle messy, heterogeneous data at scale - including schema evolution, data quality, idempotency, backfill/replay, and partial failure recovery.
• Track record of simplifying complex systems. You have taken spaghetti systems and turned them into something engineers can reason about, test, and operate confidently.
• Demonstrated P70-equivalent scope: department-level technical leadership, influence across multiple teams, and ownership of top-level technical objectives tied to business outcomes.
• Strong software engineering fundamentals. Fluency in at least one modern language (Java preferred). You write code, review code, and hold a high bar for engineering quality.
• Excellent communication skills. You can explain complex data architecture to engineers, product managers, and leadership with equal clarity.

Benefits

• Atlassian offers a wide range of perks and benefits designed to support you, your family and to help you engage with your local community.
• Health and wellbeing resources.
• Paid volunteer days.
• And so much more.
