At EY, we’re all in to shape your future with confidence.
We’ll help you succeed in a globally connected powerhouse of diverse teams and take your career wherever you want it to go. Join EY and help to build a better working world.
The opportunity
We 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.
Within 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.
It 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.
Your key responsibilities
- 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.
- 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).
- Own data durability, consistency, and recoverability: replication, backup/restore, point-in-time recovery, and cross-environment data movement, tiered by RPO/RTO.
- Build 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.
- Make 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.
- Provide the data and lineage substrate that downstream governance, observability, and AI knowledge capabilities depend on, as well as integrating with lineage tooling.
Skills and attributes for success
- Deep expertise operating production databases and data stores at scale, including relational, key-value, vector, graph, and object storage.
- Strong command of streaming and event-driven architectures (Kafka, NATS, CDC, stream processing) and the consistency tradeoffs they involve.
- A durability-first mindset: thinking in terms of consistency, recoverability, blast radius, and data correctness under failure.
- Ability to operate stateful systems consistently across managed cloud and self-hosted OSS in cloud, on-prem, edge, and air-gapped environments.
- Strong grasp of schema governance and evolution, preventing breaking changes across producers and consumers.
- Strong communicator able to guide consuming teams toward the right storage and streaming patterns.
- Orientation toward reliability and toil reduction through automation and infrastructure-as-code for data systems.
To qualify you must have
- 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 relational databases (PostgreSQL) and caching (Redis/Valkey), including HA, replication, and backup/recovery.
- Exposure to AI/ML data patterns — embeddings, retrieval, feature/state stores for agentic workloads.
- Production experience with vector and/or graph databases (Qdrant, Milvus, PGVector, Neo4j) in AI/ML contexts.
- Deep experience with event streaming and messaging (Apache Kafka/Strimzi, NATS) and change data capture (Debezium).
- Experience with stream processing (Apache Flink) and event/schema governance (CloudEvents, schema registry).
- Experience running stateful systems on Kubernetes (operators, persistent volumes, object/block storage such as MinIO/OpenEBS).
- Ability to define clean ownership boundaries and data/schema contracts with platform, trust, runtime, and delivery teams.
Ideally, you’ll also have
- Experience with durable workflow engines (DBOS, Temporal, or equivalents).
- Experience with data lineage and metadata tooling (OpenLineage, Marquez, or equivalents).
- Proven track record operating data systems under compliance, security, or regulatory constraints, including data-at-rest and in-transit protection.
- Familiarity with multi-tenant data isolation and per-tenant performance management.
- Experience with cross-environment replication and DR strategies tiered by RPO/RTO (e.g., MirrorMaker, CloudNativePG PITR).
- Exposure to regulated delivery environments (financial services, tax, healthcare, risk).
