Description

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 hands-on Firewall Security Architect to design, implement, and operate Armada’s firewall and network security platforms across core, edge, and distributed environments. This role owns firewall architecture, policy design, segmentation, and deep technical troubleshooting for high-risk and high-performance environments, including GPU-accelerated workloads. This role combines architecture ownership with hands-on implementation. The Firewall Security Architect will actively design firewall topologies, build and validate rulesets, troubleshoot complex traffic flows, and partner with engineering teams to secure production systems at scale. Location. US remote What You'll Do (Key Responsibilities) Firewall Architecture Design, deploy, and operate next-generation firewall architectures across: Core and regional data centers Edge and modular deployments GPU and high-value compute environments Build and maintain firewall topologies including: Centralized and distributed firewall models Inline, routed, and transparent firewall deployments Active/active and active/passive HA designs Perform hands-on configuration of: Firewall interfaces, zones, and virtual systems / VDOMs Routing integration and asymmetric traffic handling High-availability, failover, and state synchronization Validate firewall designs through testing, failover simulation, and performance benchmarking. Firewall Policy, Segmentation & Traffic Control Design, implement, and maintain firewall policy frameworks: Implement segmentation strategies to isolate: Actively manage and review firewall policies to prevent: Perform traffic flow analysis and packet-level validation to confirm enforcement. Advanced Traffic Inspection & Troubleshooting Perform deep technical troubleshooting Diagnose and resolve: Asymmetric routing and return-path issues MTU, fragmentation, and TCP performance problems East–west traffic inspection challenges Troubleshoot performance impacts related to: High-throughput GPU traffic Microbursts and congestion Tune firewall performance to balance security, latency, and throughput. Zero Trust & Secure Access Enforcement Implement Zero Trust concepts directly in firewall policy and architecture. Enforce strong trust boundaries between: Users, services, and platforms Internal zones and external access paths Integrate firewall enforcement with identity and access models where applicable. Design secure remote access, VPN, and private connectivity solutions. GPU & High-Performance Environment Security Design and secure firewall architectures for GPU clusters and accelerated workloads. Protect high-value compute and data paths without degrading performance. Implement inspection strategies appropriate for high-bandwidth east–west traffic. Partner with compute and platform teams during: GPU cluster bring-up Expansion and scaling Performance troubleshooting Operational Support & Escalation (L3/L4) Serve as the highest technical escalation point for firewall-related incidents. Support major incidents by: Performing live troubleshooting Validating traffic paths and policy behavior Drive root cause analysis and implement permanent corrective actions. Support change planning, maintenance windows, and post-change validation. Tooling, Automation & Standards Build and maintain firewall templates, standards, and reusable configurations. Automate firewall deployments, policy validation, and audits where possible. Define logging, telemetry, and visibility requirements for firewall platforms. Continuously improve firewall reliability, security posture, and operational efficiency. What Success Looks Like Firewall architectures are secure, performant, and resilient in production. Segmentation is consistently enforced with minimal exceptions. GPU and high-value environments remain protected without performance degradation. Firewall-related incidents are resolved quickly with clear root cause. Policy changes are predictable, auditable, and low-risk. Engineering teams trust firewall platforms instead of working around them. Required Qualifications: US Citizenship 10+ years experience in firewall, network security, or security engineering roles.
