We are seeking a Principal Architect to join our team and support our government client on a large, multi-year IT services program.
The Principal Architect is accountable for the program's reference architecture, cross-team technical standards, architecture governance and decision-making, interoperability patterns, and evaluation of major technical trade-offs. This role will work closely with client technical stakeholders, program leadership, and delivery teams to ensure the program's cloud, security, data, analytics, AI-enabled services, and integration capabilities are secure, scalable, interoperable, and aligned to mission needs.
The ideal candidate is a strategic, hands-on technology leader with demonstrated experience serving as a Principal, Chief, or Enterprise Architect on a large-scale federal IT services program. They bring deep technical expertise in cloud-native architecture, security, identity and access management, APIs, large-scale data platforms, and DevSecOps.
Essential Duties and Responsibilities
- Own, maintain, and evolve the program's reference architecture, ensuring alignment across cloud and security, data platforms, analytics, AI-enabled services, integrations, and APIs.
- Establish, document, communicate, and govern cross-team technical standards, architectural patterns, and engineering practices to promote consistency, interoperability, security, scalability, and maintainability.
- Lead architecture governance processes, including architecture review boards, technical design reviews, decision-making forums, and approval processes for significant technical and architecture decisions.
- Define interoperability patterns for data exchange, service integration, API design, event-driven solutions, external systems, and platform extensibility.
- Conduct, facilitate, and document major technical trade-off analyses to inform architecture, platform, infrastructure, security, and technology decisions.
- Evaluate architecture alternatives based on security, scalability, performance, availability, cost, maintainability, delivery risk, operational impact, and mission alignment.
- Partner with client technical stakeholders, program leadership, product leadership, and technical leads to ensure the architecture meets performance, security, privacy, availability, scalability, operational readiness, and mission requirements.
- Develop, maintain, and manage architecture-related artifacts, including reference architectures, solution architecture diagrams, technical standards, architecture decision records, integration diagrams, data-flow diagrams, and technical roadmaps.
- Ensure architecture documentation supports client oversight, audit requirements, program transition, institutional knowledge retention, and reuse.
- Collaborate with engineering, cloud, cybersecurity, data, analytics, AI/ML, product, and agile delivery teams to ensure approved architectural decisions are implemented consistently.
- Provide technical leadership and escalation support for complex cross-team architecture issues, technical dependencies, design conflicts, and integration challenges.
- Resolve architecture conflicts and provide recommendations that balance program requirements, technical feasibility, delivery schedules, risk, cost, and sustainability.
- Evaluate emerging technologies, architecture approaches, and platform capabilities to identify opportunities to improve mission outcomes, delivery speed, security posture, reliability, cost efficiency, and program sustainability.
- Support the development and refinement of technical roadmaps, modernization strategies, target-state architectures, and transition plans.
- Communicate architectural decisions, technical risks, solution alternatives, and recommendations clearly to technical and non-technical stakeholders, including government client leadership.
