Java Integration and Data Acquisition Engineer
About the role
Nationwide's Cyber Security Operations Center is hiring a hands-on Java engineer to own and extend our existing fleet of integration services that acquire, normalize, and deliver data from complex enterprise and third-party systems. Day one, you'll begin taking over existing projects that execute telemetry and retention pulls from a range of APIs — solving the hard problems that appear beyond a simple REST call: evolving contracts, pagination, throttling, async workflows, GraphQL, Microsoft Graph, gRPC, tricky encodings, and binary data. Over time, the role grows to include Angular backend development — the database access, service orchestration, and secure LLM-powered APIs that support Angular front ends.
This is a backend and integration engineering role for someone who pairs strong modern Java skills with the instincts of a protocol and data-format troubleshooter.
What you'll do
Own, operate, maintain, and extend a fleet of Java/Spring Boot integration projects running telemetry and retention pulls, in a modern CI/CD, Kubernetes, and observability environment.
Integrate with complex REST, Microsoft Graph, GraphQL, and gRPC APIs, handling auth, pagination, throttling, async workflows, and partial failures.
Parse and normalize messy JSON, XML, encoded, compressed, and binary payloads — reliably and at scale.
Build resilient, observable integrations and secure LLM-powered features with proper guardrails.
Grow into Angular backend-for-frontend development — database access, service orchestration, and secure LLM-powered APIs.
Must-have qualifications
Advanced Java and strong production experience with Spring Boot and its ecosystem.
Strong database integration skills — SQL/NoSQL, transactions, schema design, query tuning, and ORM (Spring Data, JPA/Hibernate, JDBC).
Building and operating containerized Java services through Git-based CI/CD in Kubernetes or comparable orchestration.
API integration well beyond basic CRUD — auth, pagination, rate limits, retries, and unreliable upstream behavior — including hands-on Microsoft Graph or similarly complex enterprise APIs.
Working experience consuming or implementing GraphQL, plus gRPC and Protocol BuAers.
Deep JSON and XML parsing (Jackson, StAX/SAX/JAXB) with secure parser configurations, and byte-level diagnosis of text-encoding and binary-format issues.
Resilience engineering — timeouts, retries, backoA, circuit breakers, idempotency, and checkpointing — with strong automated testing (JUnit, contract, and adversarial fixtures).
Experience integrating applications with LLM APIs or SDKs (structured output, streaming, context limits, provider failures).
Secure development practices and clear communication of protocol and data quality issues to technical and non-technical stakeholders.
Nice to have
Java 25+ and Spring Boot 4.0+; Microsoft Graph delta sync and subscriptions; Angular BFF patterns with SSE or WebSockets.
AWS, Kubernetes, Helm, Vault, GitHub Actions, Harness, Splunk, New Relic, Apigee, and Kafka.
Enterprise LLM platforms, RAG, embeddings, vector search, or agent workflows.
Working Python or scripting for prototyping of data inspection and rapid API investigation.
Experience designing backend APIs for Angular or comparable single-page applications (a growth area for this role).
