## Description

Job Description: we are seeking a Systems Integration Engineer to help design, modernize, and sustain integrations for a mission-critical, globally deployed identity and mobility platform . This is a hands-on engineering role for someone who has built and operated complex system-to-system integrations across Java microservices, event-driven architectures, edge environments, and cloud platforms . You will work on both standards-based and custom integrations spanning external data providers, identity and verification services, biometric and peripheral devices, access-control systems, and country- or customer-specific third-party platforms. The environment ranges from low-power edge clusters in austere locations to large, centralized deployments to cloud-forward AWS architectures . This role is ideal for an engineer who enjoys solving hard interoperability problems, modernizing legacy interfaces, and building resilient integrations that operate reliably under real-world network, performance, and operational constraints. What you will do Design, build, and maintain secure, reliable integrations between a distributed platform and third-party systems using REST APIs, asynchronous messaging, secure file/data exchange, and device/peripheral interfaces Modernize legacy integrations into Java-based microservices running in a distributed platform architecture Build integrations across edge, data center, and AWS cloud deployment models Engineer for resilience, observability, auditability, latency, and intermittent/low-bandwidth network conditions Integrate with government and commercial systems such as identity and verification services, traveler data platforms, biometric and document-capture peripherals, and access-control and gate systems Define interface contracts, schemas, versioning strategies, retry/idempotency behavior, and certification/test approaches Troubleshoot issues across application, data, messaging, and network layers Partner closely with software, cloud, network, QA, field engineering, analytics/observability, and security teams Required qualifications Bachelor's Degree in Computer Science or a related technical field or equivalent experience. Minimum 12 years of experience in software engineering or systems integration Strong hands-on experience building Java-based distributed services Proven production experience with API integration and event-driven messaging Experience with one or more of the following: RabbitMQ, Kafka, JMS, AMQP , or similar messaging platforms MongoDB , Elasticsearch/OpenSearch , or comparable data platforms AWS deployment and operations in production environments Experience designing and supporting integrations in high-availability, mission-critical, or regulated environments Strong understanding of integration concerns such as authentication/authorization, certificate-based security, schema evolution, error handling and retries, observability and supportability Experience modernizing legacy or monolithic integrations into service-oriented or microservices-based architectures Ability to work effectively in a highly collaborative engineering environment with direct ownership of delivery outcomes

## Requirements

Preferred qualifications Experience with  HashiCorp tooling , especially  Consul, Nomad, and Vault , or with adjacent platforms whose skills transfer quickly Experience with  AWS-native services  and infrastructure automation Familiarity with  ELK ,  Grafana ,  Kibana ,  Logstash , or other observability stacks Experience integrating  biometric devices , document readers, cameras, license plate readers, or other field peripherals Experience with  degraded, disconnected, or low bandwidth environments
