Professional Level Information:

The Senior Integration Engineer aligns as an Engineer 2 at 9th Way Insignia. This role delivers advanced systems integration across VESEE 2.0, enabling reliable, secure, and high-performance interfaces between the modernized Enrollment System (ES), legacy platforms (EDB, IVM, VistA REE), and external partner systems.

Responsibilities:

• Design, build, and maintain ES partner interfaces and internal data flows connecting EDB/IVM/VistA REE to the modernized ES.

• Implement and govern API and message standards (REST/JSON, SOAP, Kafka/AMQP) including versioning, documentation, and backward compatibility.

• Create integration patterns for synchronous and asynchronous processing, idempotency, retry/backoff, correlation IDs, and dead-letter handling.

• Develop transformation and orchestration logic (e.g., Camel/Spring Integration/NiFi) to normalize legacy payloads and enforce contract schemas.

• Collaborate with data teams on mapping, lineage, validation, and reconciliation to ensure end-to-end accuracy across enrollment workflows.

• Embed integration testing into CI/CD (contract tests, consumer-driven tests, mock services) and automate environment configuration.

• Instrument integrations for observability (Splunk/Azure Monitor), define interface SLOs, and publish runbooks and dashboards.

• Engineer authentication and authorization across interfaces (OAuth2/OIDC, mutual TLS, API gateways); enforce least-privilege and secrets management.

• Harden integrations to VA standards (FedRAMP, FISMA, IRS 1075, HIPAA) and align with Section 508 accessibility for user-facing endpoints.

• Support incident response: triage, root-cause analysis, replay/compensation strategies, and postmortems for interface failures.

• Optimize performance for high-volume eligibility and enrollment transactions, including schema/payload tuning and batching strategies.

• Contribute to transition plans, cutover rehearsals, and partner onboarding; develop checklists and training for operations teams.

Requirements:

• Bachelor’s degree in computer science, engineering, or related technical discipline.

• 6 years of integration engineering experience; 10 additional years may be substituted for education.

• Hands-on expertise with API design and integration frameworks (Spring Boot, Apache Camel, MuleSoft, or NiFi).

• Experience integrating Oracle-backed systems and legacy services; familiarity with EDB/IVM/VistA REE data flows is preferred.

• Proficiency with messaging platforms (Kafka/RabbitMQ), schema registries, and event-driven architectures.

• Strong understanding of security: OAuth2/OIDC, mTLS, JWT, secrets management, and zero-trust principles.

• Experience with CI/CD pipelines and infrastructure-as-code for integration deployments.

• Demonstrated use of observability tools (Splunk, Azure Monitor) and performance tuning for integrations.

• Excellent documentation, stakeholder communication, and cross-functional collaboration skills.

• Availability for sporadic after-hours escalation; adept at diagnosing issues under the DRE golden signals (latency, traffic, errors, saturation).
