Minimum Qualifications
Strong coding skills and a solid computer science background in algorithms, data structures, and distributed systems
5+ years experience designing, building, and operating large-scale distributed systems such as databases, storage platforms, or data processing frameworks
Hands-on experience with petabyte-scale batch data processing (MapReduce, Spark, or similar)
Proficiency in cloud-native architectures and compute orchestration on AWS (S3, EC2, EKS) and Kubernetes
Excellent interpersonal skills, with the ability to work independently and drive cross-team efforts
MS or PhD in Computer Science or related field
Preferred Qualifications
Deep familiarity with columnar and lakehouse formats (Parquet, Iceberg), and the judgment to choose between them at scale
Experience with storage internals: compaction, metadata and manifest management, indexing, and query performance tuning
Experience with workflow orchestration (e.g., Argo) and resource scheduling on shared Kubernetes clusters
Experience with key-value or online serving stores (e.g., Bigtable, HBase, Cassandra) and multi-cloud data movement
Experience with search indexing, machine learning, or NLP is a plus
