Lead Infrastructure Engineer

RapidFort, Inc.

3d • $180,000 - $225,000 • Hybrid

About The Position

RapidFort Inc. runs its core systems on infrastructure we own and operate. We are looking for a Lead Infrastructure Engineer to be the deepest technical resource on that estate — and the person our Infrastructure Engineering Manager can hand the keys to. This is a hands-on senior engineering role with a deliberate weighting: roughly 70% Linux systems engineering and automation, 30% data center hardware, storage, and network. You will spend most of your week making the Linux environment more consistent and less manual, and a meaningful part of it with your hands on physical infrastructure. It is also a deputy role. When the Infrastructure Engineering Manager is unavailable, you carry technical decision authority, change approval, and incident escalation. You will not manage people or budgets — this is technical leadership, not a management track — but you will be the reason the team does not stall when the manager is out. We are being specific about the split because the combination is uncommon. If you are strong on Linux automation but have never racked a server or traced a bad uplink, this is probably not the right fit. If you are a strong data center engineer who reaches for a script before a runbook, it likely is.

Requirements

• 7+ years engineering and administering Linux in production environments.
• Strong Bash and Python — you write production automation, not just modify it.
• Ansible (or equivalent) at fleet scale, with real opinions about idempotency and inventory structure.
• Demonstrated Linux performance troubleshooting depth.
• Hands-on data center experience: server lifecycle, firmware, out-of-band management, racking and structured cabling.
• Enterprise storage: SAN/NAS presentation, multipathing, capacity management.
• Hypervisor platform experience at cluster scale (VMware, Hyper-V, Proxmox, or equivalent).
• Solid networking fundamentals — VLANs, routing, link aggregation, DNS/DHCP, firewall rule design — and the ability to read a packet capture.
• Production on-call experience under a formal incident and change process.
• Sound escalation judgment: you know which calls to make and which to hold.

Nice To Haves

• RHCE or equivalent Linux certification; CCNA or equivalent networking certification; a virtualization platform certification.
• Prior experience acting as technical lead or deputy for a manager.
• Experience in an environment operating under ISO 27001 or SOC 2 Type 2.
• Colocation management, data center migration, or consolidation experience.
• Enough cloud literacy to hand work off cleanly to our Cloud Operations team — depth is not required.

Responsibilities

• Design, build, and harden Linux systems (RHEL/Rocky and Ubuntu) against defined baselines, and own the golden image pipeline that produces them.
• Write production automation in Bash and Python — provisioning, remediation, reporting, and evidence collection.
• Own our configuration management content in Ansible: roles, playbooks, inventory structure, and the standards they encode.
• Own patching and OS lifecycle: cadence, testing, staged rollout, exception tracking, and end-of-life upgrade planning.
• Root-cause performance problems — kernel, I/O, memory, filesystem, systemd — without waiting on a vendor.
• Replace repeatable manual work with tooling, and be able to show the hours you removed.
• Execute the server hardware lifecycle: staging, racking, cabling, firmware and BIOS, out-of-band management, and secure decommissioning.
• Diagnose hardware faults and drive vendor RMA and support cases to resolution.
• Configure and maintain enterprise storage: SAN/NAS presentation, multipathing, replication, and capacity management.
• Maintain the hypervisor estate — host builds, cluster membership, patch currency, datastore and resource pool configuration.
• Configure and troubleshoot data center networking: VLANs, trunking, link aggregation, routing, firewalls, load balancers, and VPN.
• Troubleshoot at the packet level and keep IPAM, topology, and asset records accurate.
• Participate in the infrastructure on-call rotation and serve as the escalation tier for complex incidents.
• Act as second reviewer on infrastructure designs before they are built.
• Mentor other engineers and raise the team’s automation and documentation standards.
• Deputize for the Infrastructure Engineering Manager: change approval, intake triage, maintenance window approval, and incident escalation during absence.

Benefits

• Base Salary: $180,000–$225,000 USD annually, depending on experience, qualifications, and location
• Annual performance-based bonus
• Equity: Stock options in RapidFort
• Medical, dental, and vision insurance
• 401(k) retirement plan
• Paid time off and company holidays
• Paid sick leave
• Company-provided equipment
• Professional development and growth opportunities
