Senior Network Engineer

Senior Network EngineerFervo is working to build the most cost-effective, repeatable geothermal power plants in the world. Achieving this mission requires secure, resilient, and highly available infrastructure that can scale from early-stage development to full commercial operations. Joining Fervo means operating at the intersection of energy infrastructure and modern enterprise systems—where reliability, safety, and disciplined execution are foundational.As Fervo expands across multiple sites and transitions assets into long-term operations, the network becomes a critical enabler of business performance, cybersecurity, and enterprise connectivity.

Fervo has standardized on the Fortinet platform, and this role will own the design, implementation, and ongoing operation of that platform so our environments scale securely and operate reliably across corporate, cloud, and site environments.The Senior Network Engineer is responsible for the architecture, implementation, and lifecycle management of Fervo's network infrastructure, built on the Fortinet platform—including FortiGate, FortiSwitch, FortiAP, FortiManager, FortiAnalyzer, FortiNAC, and Fortinet Secure SD-WAN—across corporate IT, cloud platforms, and site environments. This role sets technical direction for the network, delivers reliable and well-documented systems, and raises the engineering standard of the broader team.This individual will work closely with internal engineering teams, cybersecurity partners, and external service providers to design, deploy, and maintain network solutions across new site builds and existing assets. Success in this role requires deep hands-on Fortinet expertise, sound architectural judgment, and the ability to own complex infrastructure in uptime-critical environments.ResponsibilitiesDesign, implement, and maintain secure, resilient network infrastructure on the Fortinet platform across corporate, cloud, and site environmentsOwn configuration and lifecycle management of FortiGate firewalls, FortiSwitch switching, and FortiAP wireless, including high-availability design, firmware planning, and capacity managementArchitect and operate corporate SD-WAN for site-to-site connectivity, traffic steering, and WAN resilienceAuthor and maintain network design documentation, topology diagrams, and configuration standards that serve as the technical reference for the teamAdminister FortiManager for centralized policy management, device provisioning, and configuration governance across all managed devicesOperate FortiAnalyzer for logging, reporting, and event correlation, tuning outputs to support operations, security, and audit needsDeploy and manage FortiNAC for network access control, device profiling, and segmentation enforcementDrive automation of routine network changes using FortiManager scripts, APIs, and infrastructure-as-code practicesDesign and enforce network security controls—segmentation, firewall policy, and secure remote access—in alignment with company cybersecurity policiesLead firewall policy lifecycle management, including periodic rule reviews, cleanup, and change-control evidencePartner with cybersecurity teams on monitoring, logging, and incident response, leveraging FortiAnalyzer telemetrySupport network-related risk assessments, audits, and remediation activities, including evidence requests under applicable compliance frameworksServe as the senior escalation point for complex network incidents across enterprise and site environmentsLead network deployment for new site commissioning, expansions, and infrastructure upgrades, coordinating with engineering, construction, and vendor teamsPartner with managed service providers and Fortinet support to maintain uptime and drive issues to root-cause resolutionMentor engineers and contractors, raising the team's Fortinet platform proficiency and operational disciplineQualificationsRequiredBachelor's degree in computer science, engineering, information systems, or related field (or equivalent experience)10+ years of experience in network engineering or infrastructure operationsDeep hands-on experience with the Fortinet product portfolio, including FortiGate, FortiSwitch, FortiAP, FortiManager, FortiAnalyzer, FortiNAC, and Fortinet Secure SD-WANStrong experience with routing and switching protocols (e.g., BGP, OSPF), IPsec and SSL VPN, QoS, and network segmentation designExperience supporting hybrid networking environments including cloud platforms (Azure or AWS)Strong troubleshooting and diagnostic skills in complex, uptime-critical infrastructure environmentsPreferredFortinet certifications such as FCP (Fortinet Certified Professional) or FCSS (Fortinet Certified Solution Specialist) in Secure Networking or Network SecurityMulti-vendor networking experience (e.g., Cisco, Palo Alto Networks, Aruba)Experience supporting industrial control systems or operational technology environmentsFamiliarity with cybersecurity frameworks such as NIST, ISO 27001, or NERC CIPExperience in energy, utilities, oil & gas, or other regulated infrastructure sectorsExperience with network automation, scripting (e.g., Python), or infrastructure-as-code toolsLocationFervo Energy has offices in Houston, TX, Golden, CO, Reno, NV, Oakland, CA, and Salt Lake City, UT.
