Sr. Enterprise Architect Specialist

Requirements

The Enterprise Architect engaged under this request will operate in an environment characterized by:

• Statewide mission impact and executive visibility
• Integration across heterogeneous IT, OT, and security environments
• Time-critical decision-making with limited tolerance for architectural error
• Direct influence on cybersecurity posture, resilience, and operational readiness

Scope Exceeding Standard Enterprise Architect Roles

The requested role goes beyond typical enterprise architecture functions in several material ways:

Statewide, Multi-Domain Architecture Responsibility

• The role spans cybersecurity platforms, security telemetry, network visibility and detection, hybrid infrastructure, integration patterns, and resilience architecture across multiple participating entities. Decisions have cascading impacts across agencies, critical infrastructure, and incident response operations.

High-Consequence Decision Authority

• The architect is expected to make and document architecture decisions that affect detection coverage, evidentiary integrity, operational continuity, and recovery capabilities. Errors or delays have direct operational and public-interest consequences.

Advanced Architecture Governance Leadership

• The role includes establishing and operating architecture governance mechanisms that balance speed and rigor. This includes resolving cross-organizational conflicts, adjudicating risk tradeoffs, and preventing architectural debt in a rapidly evolving environment.

Deep Technical Breadth with Hands-On Expectations

• The work requires expert-level understanding across security telemetry pipelines, SIEM platforms, network detection architectures, cloud and virtualization platforms, and automation and integration tooling. The architect must be capable of both strategic design and practical validation with engineering teams.

Procurement and Vendor Evaluation Influence

• The role directly supports high-value procurements and vendor evaluations, including requirements shaping, technical evaluation input, and architectural risk assessment. These activities materially affect long-term cost, interoperability, and sustainability.

Other special requirements

• Required experience: Minimum 15 years of progressively responsible IT and enterprise architecture experience
• Preferred experience: 20 or more years of enterprise and security architecture experience in large, complex environments

Required Skills (with years)

• Enterprise Architecture (large, complex environments): 15 years
• IT Infrastructure Architecture (on-prem and hybrid): 12 years
