About the Role
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
What do we need from you
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
