Job Description
The DRR Cyber Vault redesign is defined by Charter as a principal‑architect‑level problem, not a staff‑augmentation or PM‑led exercise. Exhibit A requires tightly coupled decisions across zoning, backbone connectivity, air‑gap preservation, data diode usage, and recovery validation. This role provides single‑threaded architectural ownership across those domains. This role provides a single accountable architect responsible for delivering a HLD and LLD that satisfy all Exhibit A requirements and are approvable by Charter’s designated signatories, reducing re-work and approval delays.
Primary Responsibilities
Own end-to-end design of the Cyber Vault architecture across all five zones (Landing, Validation, Immutable, Recovery/Clean Room, Management) and the external RVZ as a separate air-gapped domain.
Lead Phase 1 comparative evaluation (Option 1 vs Option 2) and present findings to Kyle Dreas, Emil Hulongbayan, Sean Freyholtz, and Brian Waff at Week 3 decision checkpoint.
Author and own the High-Level Design (HLD) and Low-Level Design (LLD) documents, including the architectural narrative and design rationale.
Lead all design-related stakeholder workshops with Charter SMEs (Justin Fortney, Feridoon Eskandar, Emil Hulongbayan, Sean Freyholtz) and coordinate with Ray Lord and Charter NEO/PE team for backbone integration.
Present interim and final designs to Brian Waff (GVP Connectivity Solutions) and John Hendrickson (SVP NEO) for approval per Mike Baldino's stipulated requirement.
Make architectural decisions during the engagement and document them in the Decision Log; the Decision Log is the authoritative reference for design choices.
On Option 1B: provide hands-on mentoring to Charter L3–L4 engineers, structured to elevate them toward L4–L5 capability over the engagement duration.
Serve as the primary technical escalation point for any design-related issue raised by the Charter team during the engagement.
Author the Implementation Readiness Assessment Phase 5 deliverable (LOE by role, sequencing, hardware procurement list).
