About the role

We are an applied AI lab building end-to-end software agents. Our team designs and operates global office networks, focusing on reliability, security, and observability to support rapid growth and AI-powered infrastructure.

Responsibilities

  • Own scalable networks and office delivery
  • Design, deploy, and operate high-performance wired and wireless networks across offices, branches, and large campus environments, including RF optimization and resilient architectures using VLANs, LACP, OSPF, BGP, VRFs, QoS, and redundant internet and core paths.
  • Own network delivery for offices, expansions, and moves—from procurement, circuit turn-up, and vendor coordination through cutover and handoff—and, as Cognition scales, build secure connectivity across offices, cloud infrastructure, and Devin environments using VPC peering, transit networking, IPsec, GRE, or SD-WAN.
  • Create repeatable reference architectures, configuration and lifecycle standards, high-availability patterns, capacity models, inventories, diagrams, runbooks, and deployment playbooks for a growing global footprint.
  • Build observable and automated network operations
  • Own network monitoring and observability across availability, performance, capacity, and employee experience, using telemetry and analytics to identify degradation before customers report it.
  • Develop scripts, reusable tooling, and data pipelines in Python, Go, TypeScript, or another modern language to improve reliability and turn network data into actionable insight.
  • Apply infrastructure-as-code, APIs, source control, and CI/CD to automate network configuration and deployment.
  • Use Devin and AI to improve network reliability, building the skills, context, and runbooks needed for effective troubleshooting and automation.
  • Secure access and serve our stakeholders
  • Implement secure, identity-aware network access, segmentation, certificate-based authentication, and least-privilege infrastructure administration.
  • Partner with Security on firewalls, threat detection and prevention, secure remote access, and incident response.
  • Troubleshoot systematically across the OSI model, using packet analysis and telemetry to isolate root causes across clients, RF, switching, routing, applications, and external providers.
  • Build trusted relationships with stakeholders, listen to their experience, communicate clearly during incidents, and continuously improve rather than accepting that the network is “good enough.”

Qualifications

  • 5+ years of hands-on experience designing, deploying, and operating enterprise or campus networks, or equivalent practical experience.
  • Experience building and operating networks in a hypergrowth startup, with a track record of thriving amid rapid change, ambiguity, and high ownership.
  • A bachelor’s degree in computer science, information technology, network engineering, or a related discipline—or equivalent practical experience.
  • Demonstrated depth in wireless RF engineering and enterprise switching and routing, including successful delivery of branch offices or large office environments.
  • Strong knowledge of TCP/IP, DNS, DHCP, Ethernet, Wi-Fi, routing protocols, VPN and zero-trust remote access technologies such as Cloudflare WARP, and structured troubleshooting across the OSI model.
  • Experience designing for high availability, fault isolation, capacity, and scale across critical network services and connectivity paths.
  • Experience with network performance monitoring, telemetry, alerting, and analytics, with a track record of using operational data to improve reliability or customer experience.
  • Experience automating network operations with a modern programming or scripting language and applying APIs, infrastructure-as-code, Git, or CI/CD to configuration delivery.
  • Working knowledge of network security and identity controls, including IEEE 802.1X, NAC, AAA, RBAC, segmentation, IDS/IPS, or related technologies.
  • Experience coordinating carriers, contractors, and vendors while maintaining clear internal ownership of architecture, quality, documentation, and outcomes.
  • Strong judgment, communication, and service orientation, with a track record of carrying ambiguous problems through design, implementation, and ongoing operation.
