You'll be working on high-impact backend systems using Java 21, AWS, and event-driven microservices, helping to build scalable, cloud-native solutions in a modern engineering environment. Role: Senior Java Developer. Location: Miami Lakes Work scheme: Hybrid (office x3 & remote x2) Three-stage recruitment process, with a F2F interview. Responsibilities: Backend Architecture & Execution: Design, build, test, and deploy Spring Boot microservices following strict team standards. You will own your code from design to production. Distributed Systems & Event-Driven Flows: Implement publish/subscribe async messaging and handle distributed transactions using saga or orchestration patterns. API Design & Integration: Design and consume REST APIs, webhooks, and subscription APIs, while actively contributing to API contracts and versioning. Cloud-Native Engineering: Build and maintain CI/CD pipelines and infrastructure-as-code for your services, operating heavily on AWS. Operational Excellence: Diagnose and resolve issues across distributed services utilizing observability tools like New Relic, Datadog, or OpenTelemetry for logging, tracing, and metrics. Advanced AI & Agentic Workflows: Integrate LLMs into services (function/tool calling, structured outputs, and the Model Context Protocol) and build agentic workflows, ensuring AI safety and governance (guardrails, PII/PCI handling) in a regulated setting. Requirements: Technical Foundation: Senior level with 6+ years of experience building backend services in Java 21 and at least 2+ years specifically in microservices and event-driven systems. Stack Expertise: Deep, hands-on mastery of Java 21 with strong OOP and concurrency fundamentals, alongside production experience in Spring Boot and Spring Cloud. Cloud Architecture: Solid, demonstrable production experience with AWS services including DynamoDB, Kinesis, SQS, SNS, KMS, API Gateway, ECS/EKS, Lambda, IAM, and RDS. AI Proficiency: Fluency with AI-assisted development (like Claude Code or Copilot) with the critical judgment to review AI-generated code. Testing Discipline: Solid testing discipline utilizing JUnit, Mockito, and integration testing. Location & Engagement: Must be located in the Miami / Fort Lauderdale area and available to work 100% on-site for a contract engagement. Nice to Have: Financial services or payments domain experience, specifically with payment messaging standards such as ISO 20022 and the legacy FAIM (Fedwire) format. Experience with containers and orchestration (Docker, Kubernetes). Hands-on experience with Infrastructure as Code (Terraform, CloudFormation, or CDK). Experience with workflow and orchestration engines such as Temporal, Camunda, or AWS Step Functions. Advanced AI skills: vector stores/RAG, prompt engineering, and AI observability.
