Senior Integration Developer

Duties And Responsibilities

• Architect, engineer, and optimize secure, high-throughput event-streaming topologies using Java and Apache Kafka to support real-time synchronization and near-zero service disruption across the Scheduling Event Bus.
• Define Kafka application and platform patterns for topic architecture, partitioning, replication, consumer groups, schema governance, retention, replay, and production performance tuning.
• Lead the development of complex data fabrics, cloud-native microservices, Avro and JSON message schemas, and intelligent event-routing frameworks supporting more than 300 interconnected enterprise applications.
• Develop and review production-grade Java and Spring Boot services, apply enterprise design patterns, optimize JVM performance, and resolve complex concurrency, throughput, and resource-utilization issues.
• Lead the design and implementation of enterprise-scale REST and gRPC APIs, secure service endpoints, and backend integrations across web, mobile, third-party, and VA scheduling ecosystems.
• Create and validate detailed technical specifications that drive spec-driven workflows, precise code generation, and accelerated engineering through approved AI-assisted development practices.
• Partner with Cloud, DevSecOps, and Site Reliability Engineering teams to design Infrastructure as Code, CI/CD automation, and secure containerized deployments using Kubernetes and Amazon EKS in AWS GovCloud.
• Establish resiliency patterns, including idempotency, retries, dead-letter handling, circuit breakers, backpressure, failover, replay, fault isolation, and automated recovery.
• Design and implement observability capabilities, including metrics, logging, tracing, dashboards, alerts, service-level indicators, capacity analysis, and production diagnostics.
• Enforce Java coding standards, security baselines, and data-governance requirements aligned with HIPAA, NIST, and Zero Trust principles through code, design, and architecture reviews.
• Lead automated unit, integration, contract, performance, and resiliency testing and ensure release readiness for mission-critical integrations.
• Mentor junior and mid-level integration developers, lead technical reviews, establish reusable engineering patterns, and promote continuous technical upskilling.
• Support SAFe Agile and Product Line Management activities by contributing architecture decisions, technical roadmaps, delivery estimates, risk assessments, demonstrations, and stakeholder communications.

Knowledge And Skills Required

• 7+ years of experience in enterprise backend software engineering, application integration, distributed systems, or integration architecture.
• Deep production-grade expertise in Java development, Spring Boot, JVM tuning, concurrency, and enterprise Java design patterns.
• Advanced production experience with Apache Kafka, including cluster configuration, performance tuning, partition strategies, consumer-group design, retention, and schema management.
• Demonstrated ability to design high-throughput, fault-tolerant event-driven architectures and resilient asynchronous processing workflows.
• Proven experience developing cloud-native microservices in AWS and deploying containerized workloads with Docker, Kubernetes, and Amazon EKS.
• Strong proficiency in enterprise-scale REST and gRPC APIs, secure data fabrics, message schemas, and relational and non-relational database ecosystems.
• Experience with Infrastructure as Code, CI/CD automation, DevSecOps delivery practices, automated testing, and production observability.
• Strong understanding of secure software engineering, least privilege, encryption, secrets management, auditability, and regulated data-handling requirements.
• Demonstrated experience working within a structured SAFe Agile or enterprise Product Line Management environment.
• Outstanding technical leadership, mentoring, code-quality enforcement, architecture decision-making, technical writing, and stakeholder communication capabilities.

Education

• Bachelor’s degree in Computer Science, Software Engineering, or a related technical discipline; a master’s degree is preferred.

Clearance

• Must be able to obtain and maintain a federal Public Trust or Secret clearance, as required by the assignment.
