Job description

We are a Site Intelligence company transforming how industrial businesses operate. Our platform turns your existing infrastructure into a source of actionable operational intelligence, enabling teams to see what's happening, understand why, and improve continuously. By surfacing the operational signals that reports miss, we help the world's largest logistics, manufacturing, and warehousing operators stay one step ahead, making operations visible and driving proactive safety. We're a fast-growing, high-agency team building category-defining products by leveraging the latest technologies in computer vision and AI.

Industry leaders like DHL, Amazon, and Tesla trust Protex AI to drive measurable safety improvements, achieving an average 64% risk reduction within just three months of deployment. Operating in 20+ countries, Protex is the go-to safety partner for Fortune 500 manufacturing and logistics enterprises, transforming workplace safety with real-time, AI-powered insights.

About the Team

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.

About the Role

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.

What you'll own

• 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.

• Remote network debugging: Building, maintaining and owning remote network debugging and diagnostic tools for our remote fleet.

What You’ll Need

• Strong Linux fundamentals - including package management, init systems, networking, kernel/driver troubleshooting, and OS upgrade paths

• 3-8+ years of professional experience of Linux experience, systems administration, infrastructure, security engineering, or a similar hands‑on operations role

• 1 year minimum networking experience

• Excellent communication skills, with the ability to effectively convey complex technical concepts to both technical and non-technical audiences

• Experience operating a fleet of Linux devices in the field (not just servers in a data centre) - remote management, patching, observability, recovery

• Bachelor's degree in Computer Science, Engineering, or a related field

• 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

• 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

• Mindset:

  • 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

  • A security mindset - secrets management, least privilege, threat modelling, and an instinct for what a customer security reviewer is going to ask

Nice To Have

• Experience with AWS security services

• Experience with managed edge / IoT deployment platforms and remote component delivery

• Experience responding to enterprise customer security reviews at Fortune 500 scale
