Senior Networked Systems Engineer
Job Description:
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.
Key Responsibilities:
Configure, deploy, and maintain Linux-based edge systems for remote sensor and compute platforms
Work with Mikrotik (RouterOS), 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
Qualifications (preferred):
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 (RouterOS), 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), ZeroTier/WireGuard, or container-based edge systems
Benefits:
- Competitive salary
- Flexible work hours and the option for remote work.
- Opportunities for professional development and continued education.
