The Infrastructure Team builds and maintains the core foundation that powers all Protex systems, ensuring scalable data infrastructure, robust edge-to-cloud connectivity, and high-performance backend services
We support edge deployments for real-time computer vision applications and deliver resilient systems to enable proactive workplace safety at global scale
Within Infrastructure, this role sits at the intersection of systems administration, edge device operations, networking, and security, owning the layer between our cloud platform and the thousands of cameras and edge compute units running on customer sites across the world
We’re looking for a Systems Engineer, Linux focused, to own how Protex devices are provisioned, accessed, secured, and kept healthy in the field
You’ll be the technical lead for our remote access stack, OS lifecycle on the edge, fleet-wide patching and upgrades, endpoint security tooling, and the networking posture we present to some of the most security-conscious enterprises in the world
You’ll work directly with Infrastructure, Edge Engineering, IT, and customer security teams at Fortune 500 logistics and manufacturing companies
This is a hands-on role with a lot of surface area. You’ll be expected to build, document, and operate, and to raise our security bar without slowing the field team down. This role is 30% cloud, and 70% edge
OS lifecycle - Own OS updates, upgrades, and kernel/driver compatibility across the fleet. Lead evaluation and migration work when we need to move to a more enterprise-grade base OS, including compatibility testing across our video analytics stack, GPU drivers, and device management agents
Provisioning from get-go - Design how a brand-new Protex device goes from box to production: zero-touch or low-touch imaging, identity, secrets, certificates, remote access enrolment, device management registration, and first-boot validation. The bar is “an installer on a customer site can do it in minutes, every time.”
Edge security & endpoint protection - Deploy and operate security monitoring tools across remote devices via our existing device management platform. Manage sensor policy, vulnerability scanning cadence, the firewall and endpoint documentation we share with customers, and the edge-compute performance budget we’re willing to spend on security tooling
Networking & customer security posture - Maintain the firewall, port, and endpoint documentation we hand to customer IT and security teams. Be the technical voice in customer security reviews. Help close audits and procurement security questionnaires
At Protex AI, you’ll work on cutting-edge problems with a mission-driven team. You’ll have ownership, autonomy, and the opportunity to make a tangible impact on workplace safety around the world
This role in particular gives you a clean slate over the edge security and remote access story for a fleet that’s already deployed across 20+ countries - the work you do will show up in every customer security review we run
