Job Summary

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
