Job Description:

Parsons is looking for an amazingly talented Software Architect to join our team!

In this role you will lead the architecture, technical evolution, and operational design of a large-scale, globally distributed mission platform deployed across multiple countries and managed remotely from the United States.

This platform supports real-time transaction processing, distributed data management, integration with external government and commercial systems, peripheral/device orchestration, and centralized observability and administration.

The successful candidate will be the overall software architecture authority for a modern Linux-based platform composed of approximately 25 core microservices and a broad set of supporting/integration services. The environment is cloud-heavy, distributed, operationally critical, and deployed in both constrained edge settings and larger centralized/cloud environments.

This role requires someone who can define and govern architecture while remaining grounded in the realities of runtime operations, resilience, fieldability, and maintainability.

What You'll Be Doing:

• Own the overall software architecture for a distributed microservices platform running across global environments

• Maintain and evolve an ecosystem of approximately:

  • 25 core Java-based microservices

  • a comparable set of supporting and integration services

• Define and govern architecture across:

  • service boundaries and contracts

  • data flows and event patterns

  • control plane and backplane behavior

  • node roles and deployment topologies

  • observability, fault tolerance, and service recovery

• Lead architecture for a platform based on:

  • RHEL / Rocky Linux

  • Java (JDK 21 )

  • Vue.js 3 frontends

  • MongoDB for persistent data

  • Elasticsearch / Logstash and RabbitMQ for ephemeral/search/event data flows

  • Consul, Nomad, and Vault for service discovery, orchestration, and secrets management

• Architect deployment patterns for multiple node types, including:

  • server nodes

  • data nodes

  • arbiter nodes

  • workstation/user-facing nodes

• Guide the technical design of core operational services responsible for:

  • transactional processing

  • rules/screening/correlation workflows

  • authorization and access control

  • reference/master data management

  • language/internationalization support

  • health/status services

  • biometric or matching-oriented services built on open-source components

• Oversee architecture for peripheral/device services supporting integration with a broad set of external devices and sensors

• Lead integration architecture for external standards-based and partner system interfaces, including:

  • third-party government systems

  • commercial travel/identity/manifest-style systems

  • country/customer-specific extensions

• Ensure the platform remains remotely observable, supportable, and maintainable across all deployments

• Partner with cloud, network, security, data, field engineering, and operations teams to align architecture with deployment realities

• Review and guide software design decisions, technical debt reduction, modernization priorities, and roadmap sequencing

• Serve as a senior technical authority in design reviews, readiness reviews, problem resolution, and major incident analysis

What Required Skills You'll Bring:

• Bachelor’s degree in Computer Science, Software Engineering, Data Engineering, Information Systems, or related technical field. 4 Additional years of experience can substitute for a degree.

• 12 years of software engineering experience, including significant time in software architecture roles for distributed or mission-critical systems

• 5 years architecting microservices-based platforms in production

• Demonstrated ability to serve as the technical authority over a multi-service software ecosystem

• Experience guiding multiple development teams and reviewing architecture across service boundaries

• Strong written and verbal communication skills, including ability to produce design artifacts and present architecture decisions clearly

• Experience balancing long-term architecture quality with delivery constraints and operational realities

• Deep hands-on expertise with:

  • Java on modern JDKs, preferably JDK 21

  • Linux-based production environments, preferably RHEL / Rocky Linux

  • distributed service design and operational patterns

• Strong experience with:

  • MongoDB

  • Elasticsearch / Logstash

  • RabbitMQ or equivalent event/messaging platforms

  • service discovery/orchestration/secrets technologies such as Consul, Nomad, Vault, Kubernetes, or similar

• Experience designing systems that operate across:

  • constrained edge environments

  • centralized or cloud-heavy environments

  • globally distributed deployments with intermittent or variable connectivity

• Proven ability to architect for:

  • resilience and graceful degradation

  • observability and diagnosability

  • secure service-to-service communication

  • multi-role user administration and authorization

  • remote support and lifecycle management

• TS/SCI minimum clearance required.

• Domestic and/or international project travel may be required.

What Desired Skills You'll Bring:

• Master’s degree in Data Engineering, Computer Science, Analytics, or related field

• Experience with Vue.js 3 and modern frontend architecture patterns for administrative or operational interfaces

• Experience with hybrid cloud and cloud-heavy deployments where backend services are centralized and edge nodes are thin

• Experience integrating with external standards-based government, identity, travel, or partner ecosystems

• Experience designing platforms that manage or integrate with peripherals/devices such as scanners, readers, imaging devices, kiosks, or other edge hardware

• Experience with Nomad/Consul/Vault specifically in production

• Experience architecting systems with zero/low downtime upgrade paths

• Experience with semantic, cognitive, or advanced search use cases on Elasticsearch

• Familiarity with event replay, reconciliation, and offline-sync patterns

• Experience working closely with field engineering or remote deployment teams

• Experience with large-scale modernization of legacy monoliths to service-oriented or microservices-based platforms

• Familiarity with open-source biometric, matching, search, or image processing components

• Experience with multilingual/internationalized systems deployed across multiple countries or regions

• Experience supporting operational analytics/reporting services built on transaction/event data

• Experience with CI/CD pipelines and release discipline for multi-service distributed systems
