Protex AI is the AI Safety and Operations Intelligence Company.
At Protex AI, we are at the forefront of AI-driven computer vision, building a safer, smarter industrial workplace with an intelligent operating system that redefines how facilities operate. Backed by top-tier global investors, we recently secured a $36 million Series B to accelerate our mission.
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.
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 Site Reliability Engineer, Networking focussed, 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. The decisions you make show up in customer security reviews, in the way our devices land on a new site, and in how quickly we can respond when something goes wrong at 3am in a warehouse on the other side of the world.
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.
Remote access - Run and evolve our remote access fabric for edge devices. Evaluate and roll out alternative access architectures (outbound-only relays, on-demand session models, hardware-based options) to meet the security requirements of customers who can't accept the default approach.
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.
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."
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.
Systems administration - Internal Linux infrastructure, identity, SSO, MDM where relevant, and the day-to-day systems work that keeps the engineering org and the fleet running.
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
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
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
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
Experience with AWS security services
Experience with managed edge / IoT deployment platforms and remote component delivery
Experience working with edge GPU hardware and GPU-accelerated inference pipelines
Experience supporting SOC 2, ISO 27001, or similar compliance programs from the infrastructure side
Experience responding to enterprise customer security reviews at Fortune 500 scale
Experience with MDM or device fleet management tooling
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.
Protex AI is an inclusive and equal opportunities employer. We are committed to creating an equitable workplace for everyone regardless of gender, civil status, family status, sexual orientation, religion, age, disability, education level, or race.
