Job description

5+ years of hands‑on experience

Ben explicitly stated he is looking for candidates who can “hit the ground running” and suggested ~5 years as a practical minimum to demonstrate true proficiency in:

Core Technologies

• Active Directory (enterprise scale)
• Active Directory Certificate Services (ADCS)
• Public Key Infrastructure (PKI)
• Active Directory Federation Services (ADFS)

These technologies are described as the team’s “bread and butter” and are mandatory due to Tier 0 access.

Why this matters

This is not a learning role. Exxon expects deep operational judgment developed over multiple production environments.

PowerShell Automation & Infrastructure as Code (Terraform)

3–5+ years PowerShell | 2–3+ years Terraform

PowerShell:

• Heavy daily usage for automation and operational efficiency
• Candidates should be independently building and maintaining scripts

Terraform / IaC:

• Deploy infrastructure via code

The role is approximately 50% automation/engineering and 50% operations.

Why this matters

Candidates who are “GUI-only AD admins” will not succeed. Exxon is modernizing identity through automation.

Tier 0 Security Experience in Large Enterprise Environments

5+ years in high‑security / regulated enterprise environments

This role includes Tier 0 / Enterprise Administrator access

Requires:

• Experience operating under strict security controls
• Comfort with audit, compliance, and privileged access models
• Ability to pass an enhanced background check (financial, criminal, global, dark web)
• Large enterprise experience is strongly preferred, especially environments at Exxon’s scale.
