Cognition is an applied AI lab building end-to-end software agents, including Devin, the first AI software engineer. The founding team includes world-class competitive programmers, former founders, and leaders from Scale AI, Palantir, Cursor, Waymo, Tesla, Google DeepMind, and other cutting-edge AI companies. You will own the reliability, security, and evolution of Cognition's global office networks. This is a hands-on role requiring deep expertise in enterprise networking, with a builder mindset and high ownership orientation. Key responsibilities: **Scalable Networks & Office Delivery** Design, deploy, and operate high-performance wired and wireless networks across offices, branches, and large campus environments. Apply expertise in VLANs, LACP, OSPF, BGP, VRFs, QoS, and redundant internet and core paths. Own network delivery end-to-end—from procurement and circuit turn-up through vendor coordination, cutover, and handoff. 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 standards, high-availability patterns, capacity models, inventories, diagrams, runbooks, and deployment playbooks for a growing global footprint. **Observable & Automated Network Operations** Own network monitoring and observability across availability, performance, capacity, and employee experience. Use 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. Apply infrastructure-as-code, APIs, source control, and CI/CD to automate network configuration and deployment. Leverage Devin and AI to improve network reliability. **Security & Stakeholder Support** Implement secure, identity-aware network access, segmentation, certificate-based authentication, and least-privilege infrastructure administration. Partner with Security on firewalls, threat detection, secure remote access, and incident response. Troubleshoot systematically across the OSI model using packet analysis and telemetry. Build trusted relationships with stakeholders, communicate clearly during incidents, and continuously improve. This role is onsite five days a week. Cognition values teamwork and in-person collaboration. **Requirements** - 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 - 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 (e.g., 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 **Bonus qualifications** - High-density wireless, modern Wi-Fi, or large multi-site campuses - IaaS cloud networking in AWS, Google Cloud, or Azure - Advanced routing, SD-WAN, SASE, or hybrid-cloud connectivity - Network telemetry and analytics using NetFlow/IPFIX, gNMI, or similar tools - Automation using NetBox, Ansible, Terraform, or similar platforms - Applying AI or AIOps to reliability, capacity planning, or incident response - CCNP Enterprise, CWNP, or equivalent demonstrated technical depth
