Senior Network Engineer at Armada

About the Company Armada is an edge computing startup that provides computing infrastructure to remote areas where connectivity and cloud infrastructure is limited, as well as areas where data needs to be processed locally for real-time analytics and AI at the edge. We’re looking to bring on the most brilliant minds to help further our mission of bridging the digital divide with advanced technology infrastructure that can be rapidly deployed anywhere. About the role We are seeking a Senior Network Engineer to design, implement, and operate Armada’s global network infrastructure supporting modular, edge, and distributed data center environments. This role owns network architecture, complex troubleshooting, and technical leadership across routing, switching, firewalling, modern data center fabrics, and GPU-accelerated compute networks. The Senior Network Engineer partners closely with the NOC, infrastructure, security, and platform teams to ensure scalable, secure, and high-performance networks supporting core, edge, and GPU-enabled deployments. Location. This role is remote-based in the US. What You'll Do (Key Responsibilities) Network Architecture & Design: • Design and maintain scalable network architectures for edge, modular, and distributed data center environments. • Define standards for routing, switching, firewalling, segmentation, and redundancy. • Design and operate modern data center network fabrics, including: • VXLAN / EVPN-based overlay networks • Underlay routing protocols (e.g., BGP, IS-IS, OSPF) • Spine–leaf architectures and high-availability designs • Define overlay / underlay separation, IP addressing strategies, and multi-tenant segmentation models. • Design and support GPU and high-performance compute (HPC) network architectures, including: • High-bandwidth, low-latency fabrics for GPU clusters • East–west traffic optimization for distributed compute workloads • Define network designs to support AI/ML, inference, and GPU-accelerated workloads, accounting for throughput, latency, jitter, and congestion characteristics. • Collaborate with compute and platform teams to align GPU topology, network fabric design, and workload placement. • Own network design documentation including HLDs, LLDs, diagrams, and IP plans. • Evaluate new technologies and vendors to support edge, remote, data center, and GPU-enabled deployments. Implementation & Operations (L3) • Implement and support advanced L3 network services, including routing, firewall policies, VPNs, VXLAN/EVPN fabrics, and GPU-supporting network designs. • Lead complex troubleshooting involving: • Overlay/underlay interaction issues • Control-plane instability • Data-plane forwarding anomalies • Latency, packet loss, congestion, and convergence issues • Implement and troubleshoot networks supporting GPU clusters and accelerated workloads, including: • High-throughput spine–leaf fabrics • East–west traffic patterns and microburst behavior • Diagnose and resolve network performance issues impacting GPU workloads, including congestion, packet loss, and latency sensitivity. • Serve as the final escalation point for the NOC and infrastructure teams. • Perform root cause analysis (RCA) and drive permanent corrective actions for recurring or systemic issues. • Define and enforce engineering standards for production network changes. Edge & Remote Connectivity • Design and support hybrid connectivity models including ISP, LTE/5G, satellite, and private links. • Ensure reliable and secure connectivity for remote, industrial, and mission-critical edge sites. • Optimize network performance for latency-sensitive, bandwidth-constrained, and intermittently connected environments. Security & Segmentation • Design and enforce network segmentation across IT, OT, management, and customer-facing domains. • Implement and maintain firewall policies, VPNs, and secure remote access solutions. • Partner with security teams to align network architectures with security, compliance, and regulatory requirements. Automation, Tooling & Reliability • Develop and maintain automation for network provisioning, validation, and configuration consistency. • Improve monitoring, alerting, and observability in partnership with the NOC. • Drive reliability improvements, fault isolation, and MTTR reduction through design, automation, and standards. Collaboration & Technical Leadership • Mentor NOC technicians and junior network engineers. • Partner with product, infrastructure, platform, and field teams during deployments and lifecycle planning. • Provide technical leadership during major incidents, change reviews, and post-incident analysis. • Contribute to long-term network strategy and roadmap planning. Required Qualifications • US Citizenship • 7+ years experience in network engineering or infrastructure roles. • Strong expertise in routing, switching, and firewall technologies. • Hands-on experience operating complex L3 networks in production. • Proven ability to troubleshoot overlay, underlay, and performance-related network issues. • Strong documentation and communication skills. Preferred Qualifications • Certifications: CCNP, JNCIP, or equivalent. • Hands-on experience with VXLAN / EVPN and spine–leaf data center architectures. • Experience designing or operating networks for GPU clusters, AI/ML, or high-performance computing environments. • Automation experience (Python, Ansible, Terraform). • Exposure to cloud networking and hybrid architectures.
