Senior Networked Systems Engineer

Quartermaster is seeking a hands‑on, deeply technical Linux & Networking Systems Engineer to support the design, deployment, and maintenance of our edge‑connected sensing platforms. This role focuses on building and managing robust, secure, and remotely operable Linux‑based systems deployed in the field—often in challenging, bandwidth‑limited maritime environments. You'll be responsible for network configuration, system hardening, remote management, and hardware‑level debugging of edge nodes built around IoT, AI, and embedded components.

If you're fluent in Mikrotik (or similar routing environments), know how to lock down a Linux box, and enjoy working close to hardware, this is for you.

• Configure, deploy, and maintain Linux‑based edge systems for remote sensor and compute platforms
• Work with Mikrotik (Router
  
  OS), OpenWRT, or similar routers to build secure, reliable WAN/LAN connectivity for field‑deployed units
• Implement and enforce security best practices, including VPN configurations, firewall rules, SSH hardening, and OS‑level lockdown
• Debug network, system, and hardware issues across embedded systems, wireless modules, and field‑deployed compute nodes
• Create and maintain scripts and tooling for remote updates, health monitoring, and automated provisioning
• Collaborate with hardware and software engineers to integrate connectivity solutions with onboard services and cloud APIs
• Participate in design reviews to ensure system‑level reliability, security, and serviceability
• Maintain documentation for network topologies, device configurations, and secure deployment processes
• Test, validate, and stress field hardware in the lab to simulate real‑world deployment scenarios

• 8+ years of experience in Linux systems engineering, embedded networking, or IoT deployment roles
• Expert‑level proficiency with Linux (Debian, Ubuntu, Alpine or similar), including shell scripting and system‑level debugging
• Hands‑on experience configuring Mikrotik routers (Router
  
  OS), OpenWRT, Ubiquiti, or equivalent routing systems
• Strong grasp of networking fundamentals—routing, NAT, VLANs, VPNs, DNS, DHCP, and security hardening
• Experience deploying and troubleshooting headless devices in remote or unreliable environments
• Familiarity with secure update mechanisms, remote device management, and observability practices
• Comfort debugging hardware interfaces (serial, USB, GPIO, etc.) and working alongside electrical/mechanical teams

Bonus: experience with cellular networking (LTE modems, failover), Zero Tier/Wire Guard, or container‑based edge systems

• Competitive salary
• Flexible work hours and the option for remote work.
• Opportunities for professional development and continued education.
