Résumé du poste

EY is seeking an AI Systems Engineer to own the stateful backbone of EY’s AI-native platform, including data stores, memory tiers, and event streaming systems across cloud, on-prem, edge, and air-gapped environments.

This role focuses on durable, consistent access to data for agentic AI workloads, ensuring reliability, scalability, and multi-tenant isolation in regulated client contexts.

Qualifications

• Bachelor’s or Master’s degree in Computer Science or related technical field.
• 8+ years operating production data infrastructure, streaming systems, or database platforms at scale.
• Hands-on expertise with PostgreSQL and caching (Redis/Valkey), including HA, replication, and backup/recovery.
• Exposure to AI/ML data patterns with embeddings, retrieval, feature/state stores for agentic workloads.
• Production experience with vector/graph databases (Qdrant, Milvus, PGVector, Neo4j).
• Experience with event streaming and messaging (Kafka/Strimzi, NATS) and change data capture (Debezium).
• Experience with stream processing (Flink) and governance (CloudEvents, schema registry).
• Experience running stateful systems on Kubernetes (operators, persistent volumes, MinIO/OpenEBS).
• Ability to define clean ownership boundaries and data/schema contracts.

Responsabilités

• Own memory and data stores across environments and tenants including relational, vector, and object storage.
• Own event streaming and async messaging with Kafka, NATS, Debezium, Flink, and CloudEvents.
• Ensure data durability, consistency, recoverability, and cross-environment data movement with RPO/RTO considerations.
• Build and operate streaming and CDC pipelines with schema governance to prevent breaking changes.
• Make state multi-tenant and portable with proper isolation and performance.
• Provide data and lineage substrate for governance, observability, and AI knowledge capabilities.
