About the Role

we are seeking aSystems Integration Engineerto help design, modernize, and sustain integrations for amission-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 acrossJava microservices, event-driven architectures, edge environments, and cloud platforms.

You will work on bothstandards-basedandcustom integrationsspanning 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 fromlow-power edge clusters in austere locationstolarge, centralized deploymentstocloud-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 usingREST APIs, asynchronous messaging, secure file/data exchange, and device/peripheral interfaces
• Modernize legacy integrations intoJava-based microservicesrunning in a distributed platform architecture
• Build integrations acrossedge, data center, and AWS clouddeployment models
• Engineer forresilience, 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 acrossapplication, data, messaging, and network layers
• Partner closely with software, cloud, network, QA, field engineering, analytics/observability, and security teams

Required qualifications
