We are actively hiring a Software Architect with a TS/SCI clearance and polygraph to support a program in Chantilly, VA. 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 environmentsMaintain and evolve an ecosystem of approximately 25 core Java-based microservices and a comparable set of supporting and integration servicesDefine 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 managementArchitect deployment patterns for multiple node types, including server nodes, data nodes, arbiter nodes, workstation/user-facing nodesGuide 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 sensorsLead integration architecture for external standards-based and partner system interfaces, including third-party government systems, commercial travel/identity/manifest-style systems, country/customer-specific extensionsEnsure the platform remains remotely observable, supportable, and maintainable across all deploymentsPartner with cloud, network, security, data, field engineering, and operations teams to align architecture with deployment realitiesReview and guide software design decisions, technical debt reduction, modernization priorities, and roadmap sequencingServe as a senior technical authority in design reviews, readiness reviews, problem resolution, and major incident analysisRequired Skills:Bachelor's degree in Computer Science, Software Engineering, Data Engineering, Information Systems, or related technical field.
