Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
You will build a brand-new runtime protection layer for Node.js applications, defining the product and its technical approach. This includes implementing detection logic and utilizing existing threat intelligence to ensure security for managed hosting environments.
Candidates must have familiarity with Node.js and strong web application security fundamentals, along with the ability to drive product development from conception to implementation. Experience with runtime protection products and a background in malware analysis are preferred.
CloudLinux is a global remote-first company. We are driven by our principles: do the right thing, employees first, we are remote first, and we deliver high-volume, low-cost Linux infrastructure and security products that help companies to increase the efficiency of their operations. Every person on our team supports each other and does what we can to ensure we all are successful.

Imunify360 Security Suite is a product of CloudLinux Inc., the maker of the #1 OS in security and stability for hosting providers. Imunify is an innovative security solution designed specifically for shared and VPS/Dedicated servers. The automated, easy-to-use solution with the six-layer approach to security delivers comprehensive and complete attack prevention.
The missionWe protect web hosting providers and the sites running on their infrastructure through a defense-in-depth stack: web-server-layer WAF, runtime application self-protection for PHP, deep application integrations (WordPress plugins and similar), a malware scanner with cleanup capability, and network-layer firewalls and IP reputation. The pieces talk to each other, and the threat intelligence they generate at scale powers detection across the stack.
Node.js is the segment of the hosting market growing fastest, and the next layer we want to build for it is runtime protection inside the Node.js process itself. Most Node.js workloads on managed hosting today are AI-generated web apps deployed by non-technical owners who can't, won't, and shouldn't be expected to patch their own code or audit their own dependencies. We're going to defend those apps anyway — at runtime, without their cooperation, without breaking them.
You'll build that runtime protection layer end-to-end.
What you'll ownThe product is held to four numbers: runtime overhead, false positives, false negatives, and customer-escalation volume. They reflect what hosting providers and their customers care about. Hit them well and the product runs inside a meaningful slice of the modern Node.js web.
What we're looking forAn experienced researcher or engineer who can build and iterate on a brand-new product, driving both the research and the development. The hard part of this work is knowing what's malicious, what's vulnerable, and what's just an unusual but legitimate pattern — and being right about it across the long tail of frameworks, libraries, and customer code we'll encounter in production.
Must have:
Nice to have:
