Full Stack React Software Engineer (AI Infrastructure) Role in St. Petersburg, FL

Duties: Build features end to end across the Nash platform — from the React/TypeScript front end through the Java/Spring Boot services to the Oracle schema behind them. Extend the asynchronous LLM execution pipeline. Work on the message-driven services that accept requests, queue them by priority, call the model provider, and return results — including retry, failover and error handling semantics. Integrate and maintain model provider connections across Azure OpenAI and AWS Bedrock: new model onboarding, routing, provider SDK upgrades, and the differences in how each provider reports usage and errors. Design and implement throughput controls — token- and request-per-minute rate limiting, backpressure, and circuit breaking — so the platform scales toward its 1M+ requests/day target without exhausting provider quota. Own usage, cost and token accounting. Extend the data model and reporting that tracks input, output and reasoning tokens per request, and surface it in the admin UI.Deliver the self-service authoring experience that lets business teams create and tune AI use cases without hands-on engineering support. Work the full change lifecycle in a regulated environment — design, code review, governance and compliance gates, and controlled promotion across environments. Build and maintain observability — structured logging, service metrics, and dashboards in Splunk, Datadog and Dynatrace; diagnose production issues across a distributed, queue-based system. Harden the platform — service authentication and authorisation, secrets handling, and dependency currency. Collaborate with DBAs, platform, networking and compliance teams, whose sign-off the work depends on.
