Lead Software Architect

Acclaim Technical Services, founded in 2000, is a leading cyber operations, intelligence solutions and operations, network infrastructure, engineering and business enablement and enterprise operations company supporting a wide range of U.S. Federal agencies. We are an Employee Stock Ownership Plan (ESOP) company, which is uncommon within our business sector. We see this as a significant strength, and it shows: ATS is consistently ranked as a top workplace among DC area firms and continues to grow.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. (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 systems5+ years architecting microservices-based platforms in productionDemonstrated ability to serve as the technical authority over a multi-service software ecosystemExperience guiding multiple development teams and reviewing architecture across service boundariesStrong written and verbal communication skills, including ability to produce design artifacts and present architecture decisions clearlyExperience balancing long-term architecture quality with delivery constraints and operational realitiesDeep hands-on expertise with: Java on modern JDKs, preferably JDK 21+, Linux-based production environments, preferably RHEL / Rocky Linux, distributed service design and operational patternsStrong experience with MongoDB, Elasticsearch / Logstash, RabbitMQ or equivalent event/messaging platforms, service discovery/orchestration/secrets technologies such as Consul, Nomad, Vault, Kubernetes, or similarExperience designing systems that operate across constrained edge environments, centralized or cloud-heavy environments, globally distributed deployments with intermittent or variable connectivityProven 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 managementDomestic and/or international project travel may be required.Desired Skills:Master's degree in data engineering, Computer Science, Analytics, or related fieldExperience with Vue.js 3 and modern frontend architecture patterns for administrative or operational interfacesExperience with hybrid cloud and cloud-heavy deployments where backend services are centralized and edge nodes are thinExperience integrating with external standards-based government, identity, travel, or partner ecosystemsExperience designing platforms that manage or integrate with peripherals/devices such as scanners, readers, imaging devices, kiosks, or other edge hardwareExperience with Nomad/Consul/Vault specifically in productionExperience architecting systems with zero/low downtime upgrade pathsExperience with semantic, cognitive, or advanced search use cases on ElasticsearchFamiliarity with event replay, reconciliation, and offline-sync patternsExperience working closely with field engineering or remote deployment teamsExperience with large-scale modernization of legacy monoliths to service-oriented or microservices-based platformsFamiliarity with open-source biometric, matching, search, or image processing componentsExperience with multilingual/internationalized systems deployed across multiple countries or regionsExperience supporting operational analytics/reporting services built on transaction/event dataExperience with CI/CD pipelines and release discipline for multi-service distributed systemsEQUAL EMPLOYMENT OPPORTUNITY (EEO) STATEMENTATS is committed to a program of equal employment opportunity without regard to race, color, ethnicity, national origin, ancestry, citizenship, sex, pregnancy, marital status, sexual orientation, age, religion/creed, hairstyles and hair textures, handicap/disability, genetic information/history, military/veteran status, or any other characteristic or condition protected by applicable law.
