Job Description
Senior Integration Engineer delivering advanced systems integration at 9th Way Insignia. Responsible for building reliable and secure interfaces for modernized Enrollment System and legacy platforms.
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).
