Network Infrastructure Engineer

We’re seeking a Network and Systems Engineer to own the deployment, performance, and scalability of our network infrastructure across current operations and upcoming facility expansions. You’ll architect and execute network solutions, manage enterprise identity across Azure and Google Workspace, and serve as the technical authority on all infrastructure and security decisions.

This is a hands-on role that requires both strategic thinking and tactical execution. The ideal candidate thrives in fast-paced, hardware-focused environments and operates with a high degree of autonomy.

This is an onsite opportunity in our El Segundo, CA office. Responsibilities

Network Architecture & Infrastructure

• Design and execute enterprise and mission-critical network architectures across offices, test facilities, and remote environments, with deep hands-on expertise in routing protocols (BGP, OSPF), L2/L3 design, VPC/VDC, Spanning Tree, VRF, VTP, VLANs, VPNs, site-to-site connectivity, and secure tunneling architectures.
• Lead end-to-end infrastructure buildout for our new headquarters and manufacturing facilities - scoping, installing, and validating physical cabling, switches, firewalls, and wireless security appliances in collaboration with contractors.
• Implement QoS policies to prioritize critical data streams; monitor performance, proactively identify bottlenecks, and resolve complex connectivity issues.
• Design and maintain scalable, resilient network infrastructure capable of supporting high-throughput automated operations as we scale.

MSP Governance & Enterprise Systems Oversight

• Serve as the primary technical authority and escalation path for our outsourced IT partner, holding them accountable to SLAs covering tier-1/tier-2 helpdesk, device procurement, provisioning, and end-user onboarding - this role owns theoutcomes, not the tickets.
• Define, audit, and enforce configuration standards across enterprise systems managed by the MSP: Windows Server, Linux (RHEL, Ubuntu, CentOS), Active Directory, DNS/DHCP, hybrid cloud, and virtualization platforms (VMware / Hyper-V).
• Govern identity and access management across Azure AD / Entra ID and Google Workspace, including SSO and MFA policies - you don’t need to be a deep cloud sysadmin, but you need to own the standards and hold the MSP to them.
• Oversee infrastructure lifecycle management: backup and DR strategies, endpoint policies, patching routines, and server provisioning - directing execution through the MSP rather than doing it yourself.

OT, Data Pipelines & AI Infrastructure

• Support secure integration of edge automation hardware, PLCs, SCADA, and data acquisition systems with backend infrastructure, maintaining strict isolation between corporate and testing environments.
• Partner with software and systems teams on data ingestion pipelines, telemetry infrastructure, and real-time monitoring dashboards.
• Design network containment and isolation layers for AI tools and automated workflows to ensure data security and audibility.

Security & Compliance

• Partner with external compliance advisors and the MSP to implement and maintain network-level controls for NIST 800-171 and CMMC within a Zero Trust framework.
• Manage transport-layer security and encryption standards (TLS, OpenSSL, SHA-256); coordinate system hardening and vulnerability assessments through the outsourced security team.
• Develop and own security policies for endpoint management, VPN access, and data protection - setting the standard, not necessarily executing every control.

• 8+ years of experience in IT systems engineering or infrastructure roles
• Deep expertise in network protocols and fundamentals: TCP/IP, VLANs, BGP, OSPF, MPLS, routing, switching, firewalls
• Strong understanding of networking design models (L2/L3, VPC, VDC, Datacenter Zones, Spanning Tree, VRF, VTP, VLANs, and cabling)
• Hands-on experience with at least one major cloud platform (AWS, Azure, or GCP)
• Proven experience managing Windows Server, Linux (RHEL, Ubuntu, CentOS), and Active Directory environments
• Strong knowledge of systems security, access control, hardening, and encryption protocols
• Experience with identity and access management frameworks (Azure AD, Entra ID, Google Workspace, SSO/MFA)
• Proficiency in scripting and automation using PowerShell, Bash, Python, or similar
• Ability to work independently, make high-impact technical decisions, and lead projects from planning through execution
• Strong documentation habits and ability to communicate technical concepts clearly to non-technical stakeholders

Preferred Qualifications

• Familiarity with IEEE 1588 Precision Time Protocol (PTP) and experience designing or supporting time-synchronized network architectures for data acquisition, telemetry, industrial control, or distributed systems environments is preferred.
• Experience with real-time data acquisition systems, time-series databases (QuestDB, InfluxDB), or industrial control environments
• Familiarity with edge automation hardware (Opto22, PLCs) or industrial networking protocols
• Background in regulated or compliance-driven environments (defense, aerospace, critical infrastructure)
• Experience with monitoring and observability tools (Grafana, Prometheus, Datadog)
• Certifications such as CCNP, CCIE, Network+, MCSE, Security+, or relevant industry credentials
• Familiarity with NIST frameworks (800-171, 800-53) or CMMC standards
• Experience with IaC tools like Terraform, Ansible, or similar configuration management platforms, Access Control, Aerospace Engineering, Aerospace and Defense, Alternative Energy, Amazon Web Services (AWS), Ansible, Artificial Intelligence (AI), Automation, BGP, BGP Routing Protocol, Bash Scripting, CCIE - Cisco Certified Internetwork Expert, CCNP - Cisco Certified Network Professional, CentOS, Cloud Computing, Communication Skills, CompTIA Network+, CompTIA Security+, Computer Security, Configuration Management, Cryptographic Protocols, Cryptography, DHCP (Dynamic Host Configuration Protocol), DNS (Domain Name System), Data Management, Distributed Control Systems (DCS), Documentation, Electricity, Endpoint Security, Establish Priorities, Firewalls, GCP (Good Clinical Practices), Hardware Virtualization, Help Desk, High Throughput, Hybrid Cloud, IEEE (Institute of Electrical and Electronic Engineers), Identity Data Management, Information Technology & Information Systems, Information/Data Security (InfoSec), Legal, Linux Operating System, MCSE - Microsoft Certified Systems Engineer, MPLS (Multi-Protocol Label Switching), Maintain Compliance, Manufacturing, Microsoft Active Directory, Microsoft Hyper-V, Microsoft Windows Azure, Microsoft Windows Server, Network Administration/Management, Network Architecture/Engineering, Network Design, Network Operations Center, Network Protocols, Network Routing, Network Scalability, Network Support, Network Switching, Network Systems, Onboarding, Open Shortest Path First Protocol (OSPF), OpenSSL, Outsourcing, Performance Analysis, Policy Implementation, Problem Solving Skills, Programmable Logic Controller (PLC), Project Planning, Purchasing/Procurement, Python Programming/Scripting Language, QoS (Quality of Service), Red Hat Linux Operating System, Reporting Dashboards, SHA (Secure Hash Algorithm), SSL-TLS (Secure Socket Layer - Transport Layer Security), Scripting (Scripting Languages), Service Level Agreement (SLA), Single Sign-On (SSO), Software Patches, Spanning Tree Protocols, Supervisory Control and Data Acquisition (SCADA), Systems Administration/Management, Systems Engineering, TCP/IP (Transmission Control Protocol/Internet Protocol), Team Building, Team Lead/Manager, Telemetry, Time Tracking, U.S. National Institute of Standards and Technology (NIST), Ubuntu, VLAN (Virtual Local Area Network), VLAN Trunking Protocol (VTP), VMWare, VPN (Virtual Private Network), Windows PowerShell, Wireless Security
