The Solution Architect will lead end-to-end solution architecture, integration, and technical decision-making across application, cloud, data, cybersecurity, DevSecOps, testing, and user-facing capabilities.

The successful candidate will bridge strategic architecture and Agile delivery, guide technical teams through architecture runway and solution refinement, and ensure ACWS capabilities remain secure, scalable, interoperable, and maintainable in a mission-critical Army environment.

Define and maintain the end-to-end solution architecture for ACWS, aligning technical direction with program objectives, user needs, and delivery priorities.
Lead solution-level architecture across the Appian application stack, cloud infrastructure, cybersecurity, data architecture, integrations, test automation, and DevSecOps capabilities.
Serve as a senior technical design authority and primary architectural interface for government stakeholders, program leadership, and delivery teams.

Guide architectural runway, technical feasibility assessments, nonfunctional requirements, and architecture-related enablers needed for continuous delivery.
Participate in Agile and SAFe ceremonies, including PI Planning, architecture syncs, solution refinement, system demos, and retrospectives, as appropriate to the program.
Create and maintain architecture artifacts and technical documentation consistent with Army and DoD standards and approved program practices.
Provide guidance on secure cloud deployment, identity and access management, application security, resilience, performance, and scalability.
Partner with developers, Appian specialists, database administrators, DevSecOps engineers, information assurance personnel, testers, and functional SMEs to resolve architectural issues and delivery risks.
Evaluate emerging technologies, Appian capabilities, and architectural patterns and recommend practical improvements to ACWS sustainability, usability, security, and maintainability.
Prepare and deliver technical briefings, architecture recommendations, and decision materials to program stakeholders and senior leadership.
Support production troubleshooting and root cause analysis for complex cross-system issues and drive architecture-level corrective actions.
