Key Responsibilities
- Lead the architecture, design, and hands-on deployment of Isolated Recovery Environments for on-premises, cloud, and hybrid environments.

- Design and implement strong isolation controls, including network segmentation, air-gapping (physical or logical), one-way replication paths, and firewall/VLAN strategies (e.g., yellow/green models).

- Architect independent platform services within the IRE (compute, storage, networking, DNS, DHCP, monitoring, and virtualization) with no shared trust or dependencies on production.

- Design and guide Active Directory forest recovery processes executed inside the isolated environment, including separate identity planes, no trust relationships to production AD, independent time sources, and controlled validation/promotion paths.

- Define secure administration models, including Privileged Access Workstations (PAWs), restricted access methods (console/iLO preferred; no direct RDP/SSH from untrusted zones), just-in-time access, and integration considerations for PAM solutions.

- Ensure immutable storage and backup ingestion designs, and incorporate architectural knowledge of platforms such as Rubrik and Cohesity for clean data transfer into the IRE (hands-on experience with these tools is not required).

- Develop recovery runbooks, validation procedures, and testing approaches so clients can safely restore, scan, and promote workloads.

- Lead and mentor delivery teams (typically 3–15 consultants/engineers) across design and deployment phases; provide technical direction and quality oversight.

- Engage directly with client stakeholders to translate cyber resilience requirements into practical, implementable IRE designs.

- Document architectures, standards, and recommendations for client environments.

Required Qualifications
- Minimum 10 years of relevant enterprise IT security architecture, infrastructure, or cyber recovery experience.

- Proven hands-on experience designing and deploying isolated, air-gapped, or highly segmented recovery environments.

- Strong practical knowledge of network segmentation, firewalling, VLANs, routing controls, and isolation techniques in both on-premises and cloud platforms.

- Deep understanding of Active Directory, including forest recovery procedures performed in isolation, DNS/time dependencies, and identity separation principles.

- Experience with platform services (virtualization platforms such as VMware or Hyper-V, cloud infrastructure on AWS/Azure/GCP, storage, and core networking services).

- Architectural knowledge of modern backup and cyber recovery platforms (e.g., Rubrik, Cohesity) sufficient to design integration and data-flow patterns; hands-on operational experience with these tools is not required.

- Demonstrated ability to lead technical teams of varying sizes on complex infrastructure and security projects.

- Strong consulting and client communication skills.

- U.S. Citizenship required.

Preferred Qualifications
- Experience with Privileged Access Management (e.g., CyberArk), phishing-resistant MFA, and Privileged Access Workstation design.

- Hands-on work with immutable storage, object lock, or equivalent write-once protections.

- Prior involvement in ransomware recovery, clean-room recovery, or large-scale cyber resilience engagements.

- Relevant certifications (CISSP, CISM, or platform-specific credentials in VMware, Microsoft, or major cloud providers).

- Experience with Infrastructure-as-Code or automation approaches for repeatable IRE builds.

- Knowledge of related frameworks or controls (NIST, CIS, or similar) applied to recovery architectures.

Flights + hotels

This role requires you to be in the United States. If that means relocating or flying in, it is worth checking fares before you commit to a start date.
