With over 8 years of experience architecting large-scale data platforms, I have deep expertise in Apache Iceberg, Snowflake, and Spark, directly aligning with the key technologies for this role. At my previous company, I led the migration of our analytical storage to a lakehouse architecture, resulting in 40% cost reduction and improved query performance. I have a proven track record of defining technical strategy, strengthening data governance, and fostering cross-functional collaboration. I am excited about the opportunity to drive Affirm's lakehouse platform and contribute to an inclusive engineering culture. Thank you for your consideration. Sincerely, [Your Name] Copy ### Sample Interview Questions Describe a time you designed a scalable lakehouse platform. What technologies did you use and how did you balance performance, cost, and governance?I led the design of a lakehouse platform using Apache Iceberg, Spark, and Snowflake. We implemented partitioning and compaction strategies to optimize query performance, used lifecycle management to reduce costs, and enforced RBAC and data masking for governance. The platform scaled to support over 500 TB of data with 99.9% availability.How do you approach data governance in a lakehouse environment?I prioritize fine-grained access control using RBAC, dynamic data masking, and auditing. I implement cataloging and lineage tools like Apache Atlas or DataHub for discoverability. Regular reviews and automated policies ensure compliance, and I collaborate with legal and security teams to align with regulations.Can you walk through a challenging incident involving data platform performance and how you resolved it?We experienced slow queries due to small files in Iceberg. I implemented automatic compaction and optimized partitioning keys. I also added observability with metrics on query latency and storage usage. The changes reduced query time by 60% and improved overall system reliability.How do you stay current with industry trends in data infrastructure, and how have you brought innovations to your team?I regularly read papers and attend conferences like Spark+AI Summit. I introduced Iceberg’s time-travel feature for data recovery and implemented a semantic layer to simplify analytics. I also started a tech talk series to share knowledge across the team.Describe a situation where you had to influence technical strategy across multiple teams. How did you build consensus?I proposed adopting Iceberg as our table format, but teams were hesitant due to migration effort. I ran a pilot demonstrating 30% cost savings and faster queries. I showed clear benchmarks and presented trade-offs in a cross-functional meeting, gaining buy-in from engineering, analytics, and finance.
