Our client is a large, established energy organization investing heavily in enterprise infrastructure, cloud technologies, and emerging technology solutions. The company offers a collaborative IT environment with excellent benefits and significant investment in modernizing its technology platforms.
Job Description: We are seeking an experienced Lead Systems Administrator to serve as a senior technical resource within an enterprise infrastructure team. This is a hands-on technical leadership position focused on supporting and advancing the organization's infrastructure environment while helping shape its future technology strategy.
The ideal candidate will bring a strong, dedicated systems administration background with experience supporting hyperconverged infrastructure, Kubernetes, storage, networking, compute, and cloud technologies. Dell PowerFlex experience is highly preferred , although candidates with strong experience on comparable HCI platforms may also be considered.
This is not a traditional people-management position. The Lead Systems Administrator will serve as a technical advisor and mentor while partnering with other senior infrastructure resources on technology decisions, modernization initiatives, and long-term infrastructure planning.
Key Responsibilities:
- Administer, maintain, and optimize enterprise infrastructure across on-premises, hybrid, and cloud environments.
- Support hyperconverged infrastructure, with a strong emphasis on Dell PowerFlex.
- Manage and troubleshoot Kubernetes environments and their supporting infrastructure.
- Diagnose complex issues involving storage, networking, compute, virtualization, and integrated infrastructure platforms.
- Evaluate infrastructure performance, capacity, reliability, and scalability and recommend improvements.
- Help define technical standards, best practices, and future-state infrastructure strategies.
- Evaluate emerging technologies and provide recommendations regarding future infrastructure investments.
- Provide technical leadership for infrastructure upgrades, migrations, modernization efforts, and new platform implementations.
- Support Azure, Microsoft 365, and hybrid-cloud technologies.
- Contribute to automation, security, backup, disaster recovery, and infrastructure resiliency initiatives.
- Serve as a senior escalation resource for complex systems and infrastructure issues.
- Mentor and provide technical guidance to other IT team members without direct supervisory responsibility.
- Collaborate with vendors and internal technology teams during implementations, upgrades, and technology evaluations.
- Maintain infrastructure documentation, operating procedures, architecture standards, and compliance-related records.
Qualifications:
- 10+ years of dedicated systems administration or enterprise infrastructure experience.
- Strong career foundation specifically within systems administration and infrastructure.
- Minimum of 1–2 years of hands-on experience with Dell PowerFlex or another enterprise hyperconverged infrastructure platform.
- Significant Dell PowerFlex experience is highly preferred.
- Experience with comparable HCI technologies such as Dell EMC, NetApp, Cisco, or similar platforms may be considered.
- Hands-on experience supporting and maintaining Kubernetes environments.
- Strong understanding of how networking, storage, and compute work together within enterprise infrastructure.
- Advanced troubleshooting skills across multiple infrastructure technologies.
- Experience with virtualization, storage, backup, disaster recovery, and enterprise systems.
- Experience with Microsoft Azure, Microsoft 365, and hybrid-cloud environments.
- Working knowledge of infrastructure security, identity, and access-management technologies.
- Demonstrated ability to provide technical leadership and mentorship to other IT professionals.
- Experience supporting infrastructure modernization, cloud transformation, automation, or data-center initiatives.
- Strong communication, documentation, and problem-solving skills.
- Experience developing infrastructure standards or long-term technology roadmaps is preferred.
- Familiarity with Zero Trust, ITIL, SOX, or other enterprise security and compliance frameworks is a plus.
- Oil and gas industry experience is preferred but not required.
- Relevant Azure, VMware, infrastructure, or security certifications are a plus.
