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.
Responsibilities
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.
How we'll measure success
The 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.
