Endpoint Engineer

About the Company:

Our client is a cybersecurity startup founded in San Francisco, dedicated to helping organizations secure and manage their sensitive data. As a leading enterprise technology company, their product affects the personal data that people entrust businesses to store & process with care every day. Critical data in modern organizations is often sprayed across a broad set of cloud data silos, and it's a herculean task for security & compliance teams to monitor, manage, and protect this highly sensitive data. Via machine learning, their product makes it easy for organizations to discover, classify, and protect this sensitive data across their cloud footprint - such as their corporate SaaS, data infrastructure, and even their own apps. In doing so, they prevent data leakage, provide unprecedented data visibility & protection across the cloud, and enable compliance.

About the Product:

It is the unified platform that prevents data leaks and enables secure collaboration by protecting sensitive data and controlling how it's shared. For decades, legacy data leak prevention (DLP) solutions have failed to adequately protect sensitive information. Traditional DLP is outdated, intrusive, and complex - it wasn't designed for today's modern enterprise where users continuously share data across interconnected SaaS applications, endpoints, and now generative AI. Our product is the first AI-native DLP solution. We leverage AI to achieve twice the accuracy with a fraction of the false positives that overwhelm security teams. We do this without disrupting modern work patterns. Our AI-native platform spans sensitive data protection across SaaS, email, data exfiltration prevention on SaaS, endpoints, and data encryption. Our Developer Platform provides an open, flexible environment for developers to integrate our data classification and protection capabilities anywhere, including establishing trust boundaries for AI model building and consumption.

About the Role:

As a Backend Engineer, you'll enable us to deliver our platform reliably, securely, and at a massive scale. You'll help architect low latency, real-time microservices that process & detect sensitive data at scale.

This is a role in the team that owns data exfiltration prevention on endpoints and requires background in one of the following platforms: MacOS or Windows.
