This role requires deep expertise in ETL, data pipelines, data modeling, and distributed systems, with hands-on proficiency in Apache Spark, Python, and SQL.As a technical leader, you will shape architecture across team boundaries, anticipate customer needs, and make decisions that balance immediate delivery with long-term scalability, reliability, security, and cost. You will own complex, ambiguous problems from design through production and guide others toward high engineering standards. You will bring an AI-native approach to engineering—using and improving AI-assisted development practices to accelerate delivery while taking accountability for the quality, correctness, and responsible use of AI-generated work.Microsoft’s mission is to empower every person and every organization on the planet to achieve more.

Own production outcomes: Establish monitoring and operational readiness, drive incident resolution and root-cause analysis, and implement preventive improvements. Automate safe deployments, targeting zero-touch deployment where possible. Raise engineering quality: Lead design and code reviews, strengthen testing, and embed security, privacy, and compliance into solutions throughout their lifecycle.
