[Hiring] Founding RASP Engineer - Node.js @Cloudlinux

Role Description

You'll build that runtime protection layer end-to-end.

• The product: A brand-new product line, yours to define — what we intercept, what we don't, what the customer-visible surface looks like.
• The technical approach: Instrumentation strategy, deployment shape, programming language — all open. You'll consult with our architects but the direction is yours.
• Implementation, end to end: You'll have the full tooling stack we provide — LLM subscriptions, modern dev infrastructure, the works. Use what makes you fast.
• Methodology: How you build conviction in your detection logic — your call.
• Cross-layer signal: Our existing stack produces threat intelligence at unmatched scale: tens of millions of monitored sites, petabyte-scale malware sample storage, real-time domain and URL reputation, IP-level attack feeds. These are available for you to plug into. Use what helps.

Qualifications

• Familiarity with the Node.js runtime and the JavaScript ecosystem.
• Strong web application security fundamentals and current knowledge of practical exploitation.
• A working sense of how detection rules behave at scale — what catches attackers without flagging the long tail of legitimate code.
• Ability to start as the PM, architect, lead engineer, and QA for this product. You ask for resources or help when you need them; you don't wait to be told what to do.

Requirements

• Comfort directing AI coding agents to high-quality output — most of our engineering does this now.
• Prior work on runtime-protection products, application firewalls, or instrumentation tooling.
• Background in malware analysis or incident response.
• Familiarity with managed-hosting environments.
• Public security research, vulnerability disclosures, or detection rulesets you've authored.

Benefits

• A focus on professional development.
• Interesting and challenging projects.
• Fully remote work with flexible working hours, that allows you to schedule your day and work from any location worldwide.
• Paid 24 days of vacation per year, 10 days of national holidays, and unlimited sick leaves.
• Compensation for private medical insurance.
• Co-working and gym/sports reimbursement.
• Budget for education.
• The opportunity to receive a reward for the most innovative idea that the company can patent.
