Lead Software Architect (2026-0134)

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 environments
• Maintain and evolve an ecosystem of approximately 25 core Java-based microservices and 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
  
  

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

Desired Skills:

• 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
