Unleash your talent and redefine what’s possible.   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 externa
