Platform Network Engineer Job at Hermeus (Atlanta)

Job Description

Hermeus is a high-speed aircraft manufacturer focused on the rapid design, build, and test of high-Mach and hypersonic aircraft for the national interest. Working directly with the Department of Defense, Hermeus delivers capabilities that will ensure that our nation, and our allies, maintain an asymmetric advantage over any and all potential adversaries. We’re looking for a Platform Network Engineer to join our Mission Systems Engineering team at Hermeus! In this role you will design, implement, and sustain the networks that power mission-critical operations for Remotely Piloted Aircraft (RPA) systems and Ground Control Stations. This role bridges traditional network engineering with systems integration, supporting real-time communication, telemetry, and control in demanding aerospace environments. You’ll be responsible for architecting secure, high-performance networks, integrating complex avionics and mission systems, and ensuring reliable connectivity from lab environments to field deployments.

Job Responsibility

Design and implement high-performance network architectures for Ground Control Stations and RPA mission systems
Develop, integrate, and troubleshoot networked avionics and flight-critical systems across all OSI layers
Configure and optimize routers, switches, firewalls, VPNs, and wireless infrastructure for secure, low-latency operations
Validate and refine network performance through packet-level analysis, simulation, and real-world test environments
Maintain and document network topologies, configurations, and addressing schemes to ensure repeatable, scalable deployments
Collaborate across systems, software, and mission engineering teams to enable seamless connectivity and protocol compatibility
Support field and test deployments, including setup, sustainment, and rapid troubleshooting in dynamic mission environments
Responsible for designing, implementing, and maintaining reliable DevOps tools and infrastructure that will permit the deployed team to rapidly deploy, test, and verify software/hardware

Requirements

Bachelor’s degree in Computer Science, Electrical/Computer Engineering, Information Systems, or related STEM field
5+ years of experience designing, implementing, and troubleshooting physical and logical networks
Deep understanding of the OSI model with hands-on experience across Layers 1–4
Proficiency with Layer 2/3 technologies (VLANs, STP, routing protocols) and core protocols (TCP/IP, UDP, ARP, ICMP, DNS, DHCP)
Direct experience configuring routers, switches, and firewalls (Cisco, Juniper, Palo Alto) in production environments
Skilled in packet capture and analysis using tools like Wireshark, tcpdump, or Scapy
Working knowledge of Linux networking (iptables, netplan, systemd-networkd) and common serial/Ethernet interfaces
Strong analytical and problem-solving skills
able to translate system-level requirements into resilient network designs
U.S. citizenship with ability to obtain and maintain a security clearance
Travel up to 1–2 weeks as required

Nice to have

10+ years of experience designing and maintaining complex, distributed, or mission-critical network systems
Proficiency in low-level network programming, packet analysis, and custom protocol development
Experience with deterministic Ethernet, multicast, and time-sensitive networking
Hands-on familiarity with Palo Alto and Juniper platforms and configuration environments
Background supporting classified or government networks with strong understanding of cybersecurity and intrusion detection practices
Experience designing, implementing, and maintaining DevOps systems from the ground up
Relevant certifications (e.g., PCNSE, JNCIP, Network+, Security+)
Experience supporting real-time control, telemetry, or mission data networks
