Senior Network Engineer Redondo

Senior Network Engineer

Department: Information Technology

Employment Type: Full Time

Location: Redondo Beach

Compensation: $150,000 - $200,000 / year

As a Network Engineer at Impulse, you will be responsible for the full lifecycle of network infrastructure, including design, implementation, operation, and continuous improvement across enterprise, inter‑site, manufacturing, lab/test, mission‑critical, data center, and cloud‑adjacent environments.

This is a senior, execution‑focused engineering role with architecture ownership within assigned domains, operating within company reference architectures and standards defined in partnership with Network Architecture and Security leadership. The ideal candidate thrives in environments where uptime, performance, segmentation, and security are non‑negotiable and is comfortable supporting event‑driven, operationally critical activities.

While the environment is Cisco‑leaning, strong experience with other enterprise networking platforms is valued, and candidates are not required to have exclusively Cisco backgrounds.

• Own network architecture and design decisions within assigned domains (sites, network tiers, or functional areas).
• Design, implement, and maintain enterprise network infrastructure including Layer 2/3 switching, routing, segmentation, wireless, and WAN connectivity.
• Design and deploy advanced routing solutions using protocols such as OSPF and BGP, with a focus on scalability, resilience, and performance.
• Engineer segmented network environments supporting corporate, manufacturing, lab/test, restricted, and guest use cases.
• Design and implement high‑availability and fault‑tolerant network solutions (for example HSRP/VRRP, MLAG, stack‑level or chassis resiliency).
• Partner with Network Architects to align implementations with reference architectures and future‑state designs.

• Own the operational health of assigned network environments, including availability, performance, and fault isolation.
• Troubleshoot complex network issues across Layers 1 through 7.
• Participate in event‑driven operational support (for example test campaigns, mission events, critical operational activities).
• Lead or contribute to incident response, root cause analysis, and post‑mortems.
• Execute firmware upgrades, lifecycle management, and hardware refreshes.
• Participate in capacity planning, performance tuning, and growth forecasting.

• Implement network security controls in partnership with Security and Compliance teams.
• Support network segmentation initiatives including VRFs, ACL policy enforcement, and zero‑trust‑aligned access models.
• Implement and support NAC / 802.1X, firewalling, VPNs, and access control mechanisms.
• Operate networks in regulated environments aligned with ITAR, NIST 800‑171, CMMC, and similar requirements.
• Ensure logging, monitoring, and telemetry meet security and audit expectations.

• Design and manage site‑to‑site and site‑to‑cloud connectivity, including IPsec VPNs, SD‑WAN, and cloud network integrations.
• Configure and optimize QoS policies to support latency‑sensitive traffic such as voice, video, telemetry, or control systems.
• Support precision‑timed and time‑sensitive networking requirements (for example PTP / IEEE 1588, 802.1AS) where applicable.

• Apply automation and scripting (for example Ansible, Python, Terraform) to improve consistency, reliability, and operational efficiency.
• Deploy and maintain network observability solutions including SNMP, Net Flow/sFlow, and performance telemetry.
• Integrate network telemetry into broader monitoring and alerting platforms.
• Contribute to operational runbooks, standard operating procedures, and reliability improvements.

• Maintain accurate network documentation, topology diagrams, IP address management, and configuration records.
• Work closely with Infrastructure, Security, Facilities, and IT Operations teams.
• Support new site builds, expansions, relocations, and lab deployments.
