IT/Tech
Systems Administrator, IT Infrastructure, Windows Server
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:
- 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.
2. Power Shell Automation & Infrastructure as Code (Terraform)3-5+ years Power Shell | 2-3+ years Terraform
Power Shell:Heavy daily usage for automation and operational efficiency
Candidates should be independently building and maintaining scripts
Terraform / IaC:Ben specified 2-3 years as sufficient, provided the candidate can:
- Manage pipelines
- 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.
3. Tier 0 Security Experience in Large Enterprise Environments5+ 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.
