Security Engineer - Node.js Proactive Defense
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.
