Join EY and help to build a better working world.\nThe opportunity\nWe are seeking an AI Systems Engineer to own the stateful backbone of EY’s AI-native platform, including the data stores, memory tiers, and event streaming systems that hold and move every piece of state in EY’s Hybrid AI Multi-Environment Runtime (HAI). This role ensures that agentic AI workloads have durable, performant, and consistent access to data across cloud, on-prem, edge, client-managed, and air-gapped environments.\nWithin HAI, this is a distinct discipline from platform operations and model serving. This role owns everything that must remember, persist, or flow: relational and key-value state, vector and graph stores, object storage, durable workflows, and the streaming and change-data-capture pipelines that connect them. It is the layer that makes the platform stateful, reliable, and event-driven.\nIt is ideal for a data-infrastructure engineer who is equally comfortable operating production databases and high-throughput streaming systems, who treats data durability, consistency, and recoverability as non-negotiable in regulated client contexts, and who understands that state is the hardest part of any distributed platform to get right.\nYour key responsibilities\n Own the memory and data stores: relational and durable state (PostgreSQL, DBOS durable workflows), caching (Redis/Valkey), vector stores (Qdrant/Milvus/PGVector), knowledge graphs (Neo4j), and object/block storage (MinIO, OpenEBS Mayastor), across every environment and tenant.\n Own event streaming and async messaging: Apache Kafka (Strimzi), NATS JetStream (agent-to-agent), Debezium (change data capture), Apache Flink (stream processing), and Apicurio/CloudEvents (schema and event contracts).\nOwn data durability, consistency, and recoverability: replication, backup/restore, point-in-time recovery, and cross-environment data movement, tiered by RPO/RTO.\nBuild and operate streaming and CDC pipelines that move data reliably between stores and services, with schema governance and evolution that prevents breaking changes across producers and consumers.\nMake state multi-tenant and portable, ensuring isolation, performance, and consistent semantics whether running on managed cloud services or self-hosted OSS in an air-gapped environment.\nProvide the data and lineage substrate that downstream governance, observability, and AI knowledge capabilities depend on, as well as integrating with lineage tooling.\nSkills and attributes for success\nDeep expertise operating production databases and data stores at scale, including relational, key-value, vector, graph, and object storage.\nStrong command of streaming and event-driven architectures (Kafka, NATS, CDC, stream processing) and the consistency tradeoffs they involve.\nA durability-first mindset: thinking in terms of consistency, recoverability, blast radius, and data correctness under failure.\nAbility to operate stateful systems consistently across managed cloud and self-hosted OSS in cloud, on-prem, edge, and air-gapped environments.\nStrong grasp of schema governance and evolution, preventing breaking changes across producers and consumers.\nStrong communicator able to guide consuming teams toward the right storage and streaming patterns.\nOrientation toward reliability and toil reduction through automation and infrastructure-as-code for data systems.\nTo qualify you must have\nBachelor’s or Master’s degree in Computer Science or related technical field.\n8+ years operating production data infrastructure, streaming systems, or database platforms at scale.\nHands-on expertise with relational databases (PostgreSQL) and caching (Redis/Valkey), including HA, replication, and backup/recovery.\nExposure to AI/ML data patterns - embeddings, retrieval, feature/state stores for agentic workloads.\nProduction experience with vector and/or graph databases (Qdrant, Milvus, PGVector, Neo4j) in AI/ML contexts.\nDeep experience with event streaming and messaging (Apache Kafka/Strimzi, NATS) and change data capture (Debezium).\nExperience with stream processing (Apache Flink) and event/schema governance (CloudEvents, schema registry).\nExperience running stateful systems on Kubernetes (operators, persistent volumes, object/block storage such as MinIO/OpenEBS).\nAbility to define clean ownership boundaries and data/schema contracts with platform, trust, runtime, and delivery teams.\nIdeally, you’ll also have\nExperience with durable workflow engines (DBOS, Temporal, or equivalents).\nExperience with data lineage and metadata tooling (OpenLineage, Marquez, or equivalents).\nProven track record operating data systems under compliance, security, or regulatory constraints, including data-at-rest and in-transit protection.\nFamiliarity with multi-tenant data isolation and per-tenant performance management.\nExperience with cross-environment replication and DR strategies tiered by RPO/RTO (e.g., MirrorMaker, CloudNativePG PITR).\nExposure to regulated delivery environments (financial services, tax, healthcare, risk).\nWhat we offer you\nAt EY, we’ll develop you with future-focused skills and equip you with world-class experiences. We’ll empower you in a flexible environment, and fuel you and your extraordinary talents in a diverse and inclusive culture of globally connected teams.
