What We're Building

We're building the AI-native social engineering defense platform.

This means we're designing scalable systems that monitor billions of domains, social media accounts, apps, dark web forums, etc., and leverage AI agents to identify and neutralize digital threats.

What We're Looking For

We’re looking for an experienced backend engineer to build out the infrastructure required to rapidly scale up our data platform and our engineering organization. A few examples of the work we’ve done recently:

• Built self-hosted Elasticsearch infrastructure on Kubernetes, enabling real-time search across millions of alerts and associated metadata.

• Built out a robust DBT transformation layer, enabling customers, engineers, and analysts to reliably model and query large-scale event data, improving time-to-insight and reducing data inconsistencies.

As part of our NYC/SF team (in-office min 3x/week), you’ll:

• Work on a wide range of asks that protect billions of people from digital impersonation

• Have complete end to end ownership - from directly collecting customer requirements to continuously iterating on shipped releases.

• Mentor junior engineers, make key product decisions, and foster a high-performing team culture

What We Offer

🚀 A mission-driven culture with low ego, high ownership, deep customer obsession, and exceptional talent density

🍽️ Free lunch and dinner in the office

🌴 Flexible PTO

✈️ Quarterly team offsites
