Bare metal, data center & network security
Design and implement secure bare-metal and private-cloud architectures (servers, storage, out-of-band management, BIOS/UEFI/BMC firmware posture)
Harden physical and virtual fleets: OS baselines (Linux/Windows), CIS benchmarks, patch and vulnerability management, and secure boot / measured boot where applicable
Hands-on firmware, BMC/iDRAC/iLO, PXE/Kickstart provisioning, and hardware lifecycle security
Build and secure network foundations: segmentation, load balancers, DNS, PKI, NAC, and IDS/IPS on real hardware
Own hybrid connectivity between on-premises and cloud (site-to-site VPN, Direct Connect / Interconnect / ExpressRoute, SD-WAN, zero-trust access)

Assist with security assessments and audits of physical, on-premises, and hybrid infrastructure
Monitor and remediate infrastructure to comply with regulations and best practices (e.g., PCI, NIST CSF, GDPR, HIPAA)
Platform, containers & developer enablement

Develop dashboards and alerts from security metrics across physical and platform layers
Develop and maintain infrastructure security policies, standards, and procedures from metal through platform
Own security projects end to end: identify issues and implement solutions
Stay current with emerging threats and mitigations for bare-metal, firmware, network, and hybrid-cloud infrastructure
BASIC QUALIFICATIONS: Bachelor's degree in Computer Science, Cybersecurity, or a related field
3–5 years of experience in infrastructure security, platform security, or related hands-on roles
Proven experience securing bare-metal, data-center, or private-cloud environments (not cloud-only resumes)
Hands-on experience with firmware, BMC/iDRAC/iLO, PXE/Kickstart provisioning, and hardware lifecycle security
Strong proficiency with Puppet for configuration management and fleet hardening in production
Strong understanding of network security concepts and protocols, including hands-on work with firewalls, segmentation, and hybrid connectivity
Experience with hybrid identity (AD/LDAP or similar) integrated or federated with cloud IAM
Experience with Infrastructure as Code (e.g., Terraform) applied to physical or VM fleets
Familiarity with containerization and Kubernetes security implications, including on-premises or bare-metal clusters
Experience with languages (e.g., Python, Bash and Golang) for automation and tool development
Familiarity with regulatory compliance requirements (e.g., GDPR, HIPAA, PCI DSS, NIST CSF)
Experience in banking, money transmission, P2P payments, or similarly regulated financial platforms
Proactive mindset with strong ownership, critical thinking, and problem-solving skills
Located in the SF Bay Area, Austin, New York, Palo Alto, or Seattle, or willing to relocate to a US office

Relevant security certifications (e.g., CCSP, CSSK, OSCP, network or cloud security specialty)
Strong proficiency with Python and Terraform on production fleets
Deep expertise in Kubernetes and container security on bare metal or private cloud
Experience with multi-cloud and cloud-to-on-prem security
Knowledge of CI/CD best practices and tools; hands-on GitHub Actions or equivalent
Experience with observability and security operations tooling (e.g., Prometheus, Grafana, CloudWatch, Karma; SIEM platforms such as Wazuh)
Experience building custom security tools or integrations
Interest in leveraging AI for infrastructure security monitoring and automation
Contributions to open-source infrastructure or security projects
Experience securing AI/ML and GPU workloads on bare metal or hybrid infrastructure
