Job Description:

Parsons is seeking a Senior 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

8+ 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

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

Why join Parsons in this role

Work on technically demanding integration challenges with real operational impact

Modernize a global platform from legacy interfaces to resilient microservices

Deliver software, edge systems, cloud, networking, and observability solutions

Join a team where senior engineers have meaningful technical ownership and influence
