Network Systems Engineer

You'll deploy, document, and maintain robust network architectures, cloud infrastructure integration, and related network services (DNS, DHCP, VPN, etc.) that meet rapidly growing needs while facilitating a successful startup culture. You'll bring expertise in networking technologies, security best practices, and performance optimization, working hands-on in a fast-paced startup environment. You'll work across the entire organization, thriving on autonomy, technical depth, and cross-functional collaboration, while staying focused, moving fast, self-directing, and learning on the fly.

Responsibilities

• Design, implement, and manage enterprise network infrastructure with a strong focus on Juniper Networks switching, routing, campus access, aggregation, and management platforms
• Own hands-on Junos configuration, validation, troubleshooting, upgrade planning, and lifecycle management for Juniper EX Series switches and related network infrastructure
• Build resilient LAN/WAN designs across facilities, including redundant access and aggregation layers, structured VLAN design, routing boundaries, uplink strategy, and standards-based interconnects
• Integrate Juniper campus networks with Fortinet or other firewall platforms, VPNs, cloud connectivity, wireless infrastructure, and critical network services such as DNS, DHCP, NTP, and monitoring
• Ensure network security through proper segmentation, firewall filters/ACLs, management-plane protections, logging, monitoring, and adherence to security policies and NIST-aligned control expectations
• Collaborate with IT, security, software, avionics, operations, and facilities teams to develop and maintain secure, reliable network access policies and site connectivity standards
• Lead network upgrades, migrations, and system integrations, including replacing legacy equipment with scalable enterprise Juniper-based infrastructure
• Implement automation, monitoring, telemetry, and configuration-management practices to proactively detect, diagnose, and resolve network issues
• Document network architectures, configurations, diagrams, standards, processes, and standard operating procedures to support operational continuity and audit readiness
• Assist remote teams including IT, software, and avionics with on-site support of equipment and software tools at the launch complex at Cape Canaveral
• Perform additional duties as assigned to support organizational goals and objectives
• Travel occasionally to other facilities

Requirements

• Exceptional understanding of the OSI model, IP networking standards, packet flow, and enterprise network design fundamentals
• 5+ years of experience in network engineering, including designing, monitoring, and troubleshooting LAN/WAN networks in enterprise/campus environments
• Hands-on experience with Juniper Networks devices and Junos OS, particularly EX Series switching platforms
• Expert knowledge of switching and routing technologies, including VLANs, trunks, LACP, LLDP, RSTP/MSTP, ARP, VRRP, OSPF, BGP, and route redistribution
• Experience designing resilient campus/access-layer architectures using Juniper features such as Virtual Chassis, MC-LAG/ESI-LAG, redundant uplinks, and structured aggregation/access designs
• Hands-on experience integrating enterprise switching with firewalls and VPN platforms, especially Fortinet, Palo Alto, Cisco, Juniper SRX, or comparable security appliances
• Ability to configure, validate, and troubleshoot Junos routing, switching, ACL/firewall filters, interface behavior, optics, PoE, DHCP relay, and management-plane access
• Strong troubleshooting and problem-solving skills with the ability to isolate complex network issues using packet captures, telemetry, logs, CLI diagnostics, and structured test plans
• Experience with enterprise WiFi technologies, including design, implementation, troubleshooting, and optimization of wireless networks for high-density environments
• Strong technical acumen with the ability to perform hands-on support and troubleshooting across a broad range of IT systems, including networking, hardware, software, and end-user support
• Excellent written and verbal communication, including the ability to document designs, standards, runbooks, and operational procedures clearly
• Bachelor's degree in Computer Science, Information Technology, a related STEM field, or equivalent experience
