Application Integration Engineer

What You Will Do:

We are seeking a mid-level Application Integration Engineer to implement integration capabilities for a large-scale platform modernization effort. This role will support the Solution Architect and senior technical leads by developing Java/Spring Boot RESTful APIs, configuring AWS cloud-based integration components, supporting data exchange between Java and Python applications, and helping connect modernized vendor-delivered capabilities with existing legacy systems.

• Implement application integration capabilities in support of a large-scale platform modernization program delivered through iterative agile execution.
• Develop, configure, test, and support RESTful APIs, service integrations, messaging flows, data transformation logic, orchestration components, and interface services that connect legacy Java-based applications with cloud-native or microservices-based platforms.
• Work under the guidance of the Solution Architect to apply approved architecture patterns, API standards, data integration approaches, security expectations, and implementation guidance.
• Select and implement appropriate integration patterns, including synchronous APIs, asynchronous messaging, event-driven integration, batch processing, and workflow orchestration.
• Implement secure AWS access and connectivity using least-privilege IAM, KMS, Secrets Manager, VPC and private connectivity, resource policies, and secure API exposure patterns.
• Design resilient integrations using retries, timeouts, idempotency, dead-letter queues, back-pressure controls, schema-evolution practices, and failure-recovery mechanisms.
• Establish operational visibility through CloudWatch metrics, centralized logging, alarms, distributed tracing, dashboards, and documented operational runbooks.
• Support production deployment and operations by implementing deployment and rollback strategies, responding to incidents, managing capacity and service quotas, and considering cost implications.
• Implement secure integrations using authentication and authorization technologies such as OAuth2, OpenID Connect (OIDC), SAML, JWT, or similar standards.
• Support event-driven architectures, messaging systems, and asynchronous processing using technologies such as SQS, SNS, EventBridge, Kafka, or similar platforms.
• Develop and support Oracle database and SQL-based integration activities, including query development, data modeling support, troubleshooting, and performance tuning.
• Collaborate with application development, data, security, DevSecOps, and vendor teams to clarify interface requirements, resolve dependencies, and support end-to-end integration testing.
• Document technical implementation details, interface behavior, data mappings, API contracts, configuration notes, test results, and operational support considerations.
• Troubleshoot integration defects, interoperability issues, data quality issues, API errors, authentication or authorization issues, database performance concerns, cloud service issues, and deployment-related problems across distributed applications.
• Support CI/CD, automated testing, code reviews, release readiness activities, production deployment planning, and operational transition for integration components.
• Contribute to continuous improvement by identifying opportunities to simplify integrations, improve reliability, reduce manual effort, and strengthen platform maintainability.

What You Will Need:

• Must be able to OBTAIN and MAINTAIN a Federal or DoD "PUBLIC TRUST"
• Minimum of FIVE (5) to EIGHT (8) years of experience in software engineering, application integration, API development, data integration, cloud-enabled application delivery, distributed application support, or related technical roles.
• Strong proficiency in Java, Spring Boot, RESTful API development, scalable microservices, service integration patterns, and integrations between legacy Java-based applications and modern cloud-native platforms.
• Experience integrating Java and Python applications using APIs, messaging, data transformation, orchestration, and related interoperability techniques.
• Experience with cloud-native application development using AWS services such as Lambda, ECS/EKS, SQS, SNS, EventBridge, API Gateway, DynamoDB, CloudWatch, and related cloud-based integration, monitoring, deployment, and troubleshooting capabilities.
• Experience implementing secure integrations using OAuth2, OpenID Connect (OIDC), SAML, JWT, or similar authentication and authorization technologies.
• Strong understanding of enterprise integration patterns, API design, event-driven architectures, messaging systems, and asynchronous communication using technologies such as SQS, SNS, EventBridge, Kafka, or similar platforms.
• Solid experience with relational databases such as Oracle, including data modeling, query development, SQL optimization, transactions, troubleshooting, and performance tuning.
• Working knowledge of NoSQL databases such as DynamoDB, MongoDB, Cassandra, or similar modern distributed data stores.
• Ability to design and develop domain models and implement domain-driven design (DDD) principles for complex business applications.
• Experience implementing data integration solutions involving data mapping, transformation, validation, synchronization, migration activities, batch processing, event-driven processing, or canonical data models.
• Experience developing, testing, troubleshooting, and supporting distributed applications across APIs, databases, cloud services, and legacy systems.
• Familiarity with CI/CD pipelines, automated testing, Git-based source control, DevSecOps practices, SDLC processes, agile delivery, and release management.
• Ability to interpret architecture guidance, interface specifications, API contracts, data mappings, user stories, acceptance criteria, and technical design documentation.
• Strong analytical and problem-solving skills with the ability to diagnose and resolve complex integration and interoperability issues across applications, APIs, data flows, authentication or authorization mechanisms, databases, cloud services, and deployment environments.
• Strong documentation skills, including the ability to maintain implementation notes, API documentation, interface specifications, data mappings, test evidence, and support handoff materials.
• Ability to work collaboratively with Solution Architects, developers, DevSecOps engineers, data teams, vendors, security teams, Product Owners, Scrum Masters, Federal stakeholders, and business stakeholders in an Agile environment.
