About the Role: We are seeking a Network Engineer to support the design, deployment, and ongoing operation of our corporate network infrastructure across offices, warehouses, and data centers. This role is ideal for an engineer who has moved beyond foundational networking and is ready to take ownership of medium-to-large network projects while continuing to grow toward an intermediate or advanced-level role. You'll work closely with IT Operations, Systems Engineering, Security, and Project Management teams to ensure reliable, secure, and scalable network solutions across all corporate locations, with a clear path toward Senior Network Engineer responsibilities as you grow in the role.

What You'll Bring to the Team: * 5+ years of hands-on experience as a Network Engineer in office, warehouse, or datacenter environments. * Strong understanding of TCP/IP, DNS, DHCP, VLANs, and routing. * Solid knowledge of Layer 2 and Layer 3 networking protocols. * Experience with wired and wireless enterprise networks. * Practical experience with circuit provisioning and carrier management. * Ability to analyze and troubleshoot network connectivity issues efficiently using Wireshark. * Strong troubleshooting, problem-solving, and technical documentation skills. * Comfortable owning network components or projects end-to-end. * Ability to work effectively across IT, Security, and Operations teams and explain technical concepts to non-technical audiences. * A growth mindset: eager to learn new platforms and progress toward senior-level responsibilities. * Bachelor's degree in IT, Computer Science, or equivalent practical experience. Bonus Points * Cisco Meraki experience (firewall, switching, wireless). * CCNA or equivalent certification. * Experience with WAN technologies (MPLS, DIA, SD-WAN), VPNs, and monitoring tools. * Familiarity with Lucid, Jira, IAM platforms (e.g., Okta, including SSO/SCIM/OIDC), low-code automation tools (e.g., Workato, Postman), and AI-assisted workflows.
