Overview

Working at Atlassian

Responsibilities

As a Principal Engineer in Search Platform, you will be a key technical leader for the Search Data pillar. You will help build and evolve a cutting-edge platform for integrating, processing, indexing and searching massive volumes of unstructured data across 100+ sources. You will bring deep expertise in large-scale data platforms, streaming and batch processing, and distributed systems to solve complex problems across infrastructure, data reliability, and developer productivity. Data is messy and hard — and it's the most critical, make-or-break input for Search and AI.

You will be expected to lead other engineers, drive technical direction within your scope, and own outcomes from design to launch. Your role is central to identifying and executing step-change improvements that deliver a world-class end-to-end search experience, powered by rich data that is fresh and reliable across all apps.

Responsibilities:

• Collaborate with technical leads, partner teams, and internal customers to define technical strategy and architecture for key areas within Search Data.

• Lead the evolution of data pipelines and platform components to meet the demands of both real-time search freshness and AI/agentic retrieval at enterprise scale.

• Make sound architectural trade-offs between freshness, correctness, cost, and operational simplicity — and own the outcomes within your scope.

• Drive the simplification and modernization of complex, legacy data processing systems. Identify and eliminate unnecessary complexity. Design systems that are understandable, testable, and operable.

• Apply and promote 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 systems and processes within your scope. Proactively identify opportunities for continuous improvement and track key operational metrics.

• Improve developer productivity by championing agents, automation, and tooling that unlock team potential. Foster a culture of high ownership, rigorous testing, safe rollouts, and data-driven engineering.

• Mentor engineers and contribute to building an open, innovative, and operationally responsible team culture.
