[Hiring] Senior Infrastructure Lead @6 Degrees Health Dx

Role Description

We’re seeking a Senior Infrastructure Lead to join our dynamic team and drive the automation, scalability, and reliability of our platforms. You’ll own and operate a small-to-mid scale hybrid infrastructure environment. Lead day-to-day reliability, security, lifecycle management, and modernization across on-prem Dell HCI, networking, Cisco firewalls, Windows/SQL Server, and Azure infrastructure. Hands-on experience with running infrastructure and projects.

Essential Role Responsibilities

• On-Prem Infrastructure (Dell HCI / Virtualization / Compute / Storage)
  • Operate and maintain Dell HCI cluster(s): capacity planning, node lifecycle, firmware/driver alignment, performance tuning, and incident response.
  • Manage hypervisor platform (VM provisioning, HA/DRS equivalents, templates, resource governance).
  • Own storage posture: performance, redundancy, snapshots, replication (where applicable), and failure domain design.
• Network & Security (Cisco Firewalls / Core Network)
  • Administer network switching/routing, VLAN design, IP addressing, DNS/DHCP integration, and site connectivity.
  • Configure and manage Cisco firewalls: NAT, VPN (site-to-site/remote access), segmentation, rule hygiene, logging, and periodic access reviews.
  • Partner with security/compliance to implement hardening, vulnerability remediation, and audit evidence.
• Windows Server / SQL Server / Core Services
  • Manage Windows Server infrastructure: AD, Azure AD, file services, and patching.
  • Administer SQL Server: installs/upgrades, performance tuning, backup/restore, HA/DR strategies, and security (least privilege, encryption, auditing).
  • Own backup/restore validation (not just “backup succeeded”): routine recovery tests and documented RTO/RPO.
• Monitoring / Observability / Tooling
  • Own monitoring stack: define SLOs, thresholds, alert routing, and noise reduction.
  • Maintain logging and event visibility across servers, network devices, firewalls, and Azure resources.
  • Build runbooks and automate common remediation tasks.
• Cloud Infrastructure (Hybrid Cloud)
  • Design and operate Azure IaaS/PaaS foundations: subscriptions, identity integration, VNets, subnets, NSGs, routing, private endpoints, and connectivity using VPN.
  • Deploy and manage Azure compute/storage: VMs, Azure Storage, Azure Backup, Azure Site Recovery.
  • Implement governance: tagging, policy, RBAC, budgets/cost controls, and standardized deployment patterns.
  • Azure key management, encryption, logging, and access controls.
• Operational Excellence / Change / Vendor Management
  • Run change management for infrastructure modifications: risk assessment, rollout/rollback plans, and maintenance windows.
  • Manage vendors/support contracts (Dell, Cisco, Microsoft) and coordinate escalations.
  • Create/maintain infrastructure documentation: diagrams, inventories, standard builds, DR plans, and operating procedures.
  • Assist with HITRUST certifications and related controls.

Qualifications

• 10+ years in infrastructure engineering/administration with ownership of production environments.
• Experience in Cloud Environments is required.
• Experience in migration from on-prem to cloud.
• Proven experience managing Dell HCI clusters (or equivalent HCI) in small-to-midscale environments.
• Strong networking fundamentals (routing/switching, VLANs, DNS/DHCP, VPN).
• Hands-on administration of Cisco firewalls (rule management, VPN, logging, segmentation).
• Strong Windows Server administration and enterprise hygiene (patching, hardening, identity/access).
• Strong SQL Server operational experience (backup/restore, performance, security, upgrades).
• Practical Azure infrastructure experience: networking, compute, storage, RBAC, governance, and monitoring.
• Monitoring/alerting ownership experience with at least one major monitoring platform (examples: site 24x7, Lan Sweeper, Manage Engine, Teramind, PagerDuty, Jira, Rapid 7, Azure Monitor).
• Ability to troubleshoot across layers (hardware/hypervisor/OS/network/application dependencies).
• Clear written documentation and incident communication.

Preferred / Nice-to-Have

• DR architecture (replication, failover testing) and formal compliance exposure (SOC 2, HIPAA, HITRUST).
• Scripting proficiency: PowerShell (strongly preferred), Python (optional).
• Experience with SIEM/log pipelines (Manage Engine, Wazuh).

Essential Role Functions

• Must have the ability to read and understand various process flows and procedures.
• Strong internal and external communication skills, both verbal and written.
• Must be willing and able to work a 5-day schedule and additional hours beyond regularly scheduled shift to cover vacancies, if necessary.

• Must be able to operate computers and phones to support position requirements.
• Strong Microsoft Office Skills are a must.

Benefits

• Competitive compensation.
• Medical, Dental, Vision and Other Outstanding Ancillary Benefits.
