- Experience managing on-premise physical hardware infrastructure
- Strong scripting skills in Bash and/or Python
- Experience with automation and configuration management tools (e.g., Ansible)
- Experience implementing or working with Terraform or other Infrastructure-as-Code tooling
- Solid understanding of Disaster Recovery principles and testing
- Experience working alongside or managing Managed Service Providers (MSPs)
- Good understanding of infrastructure security fundamentals and system hardening
- Experience working within a financial services firm or similarly regulated environment
Experience, Knowledge & Skills
- 5+ years infrastructure experience.
- A pragmatic, hands-on infrastructure engineer who enjoys solving complex technical problems.
- An automation-first mindset, with a drive to eliminate repetitive manual tasks.
- Strong sense of ownership and operational discipline.
- Comfortable challenging legacy processes and proposing modern alternatives.
- Continuous improvement mentality with a focus on reliability and efficiency.
- Good systems thinking and architectural awareness beyond individual servers.
- Ability to work independently while collaborating across technical teams.
- Clear communication skills and ability to engage with both technical and non-technical stakeholders.
- Active Directory administration
- Pure Storage (Pure SAN)
- HashiCorp stack (Vault, Consul, Nomad)
- VMware
- Exposure to vulnerability management or security auditing practice
