Senior Network Architect; remote

Description

Fervo 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 corporate offices, cloud environments, and operating sites, network architecture is a critical enabler of safety, cybersecurity, reliability, and business performance. Fervo uses Fortinet as the core enterprise IT networking platform and Cisco within portions of its operational technology environment. This role will ensure those environments are secure, resilient, well integrated, and increasingly automated.
