Run and evolve our remote access fabric for edge devices
Deploy and operate security monitoring tools across remote devices via our existing device management platform
Own OS updates, upgrades, and kernel/driver compatibility across the fleet
Design how a brand-new Protex device goes from box to production
Maintain the firewall, port, and endpoint documentation we hand to customer IT and security teams
Internal Linux infrastructure, identity, SSO, MDM where relevant, and the day-to-day systems work that keeps the engineering org and the fleet running

Requirements

5+ years of professional experience in systems administration, infrastructure, security engineering, or a similar hands on operations role
Strong Linux fundamentals - including package management, init systems, networking, kernel/driver troubleshooting, and OS upgrade paths

Bachelor's degree in Computer Science, Engineering, or a related field
Hands on experience with a mesh/VPN or zero trust remote access solution
Solid networking knowledge: TCP/IP, DNS, NAT/firewalls, outbound only architectures, certificate handling, and how to explain all of the above to a customer's security team
Experience deploying and operating endpoint security and vulnerability scanning tools at scale
Experience with a major public cloud provider, particularly the compute, identity, monitoring, and edge/IoT services
Proficiency coding in Python - comfortable writing automation, tooling, and small services rather than only shell one liners
Additional scripting and automation skills (Bash or similar) to make manual fleet operations go away
A security mindset - secrets management, least privilege, threat modelling, and an instinct for what a customer security reviewer is going to ask
Owns their work end to end: planning, delivery, documentation, and cooperation across teams
Helpful and responsive - willing to jump on a field issue with urgency when an edge device or a customer is impacted
Bias to write things down so the next person doesn't have to ask
