About The Position

At Snowflake, we are powering the era of the agentic enterprise. To usher in this new era, we seek AI-native thinkers across every function who are energized by the opportunity to reinvent how they work. You don’t just use tools; you possess an innate curiosity, treating AI as a high-trust collaborator that is core to how you solve problems and accelerate your impact. We look for low-ego individuals who thrive in dynamic and fast-moving environments and move with an experimental mindset — who rapidly test emerging capabilities to discover simpler, more powerful ways to deliver results. At Snowflake, your role isn't just to execute a function, but to help redefine the future of how work gets done.
We are building the next generation of cloud security infrastructure, focusing on advanced Data Exfiltration Protection (DXP) and unified Data Movement Policies (DMP). Our mission is to provide seamless, context-aware security that protects sensitive data without hindering developer velocity. We are looking for a visionary Principal Engineer to lead the technical strategy and architecture for our Data Movement and Perimeter control systems.
As a Principal Engineer in the Data Protection group, you will be the technical lead for the Data Exfiltration Protection (DXP) and Data Movement Policy (DMP) initiatives. You will bridge the gap between high-level security policy and low-level system enforcement, ensuring that our perimeter controls are robust, scalable, and deeply integrated with context-aware access policy frameworks. You will be responsible for the architectural evolution of our egress control systems, moving from simple IP-based rules to sophisticated, content-aware, and identity-driven data movement governance.

Requirements

• 12+ years of experience in software engineering, with at least 5 years in a principal or architect role focusing on infrastructure or security.
• Deep understanding of network security protocols (TLS/SSL, HTTP/S, DNS), Zero Trust architectures, and Data Loss Prevention (DLP) technologies.
• Proven track record of designing and deploying high-scale distributed systems (Java, Go, or C++).
• Strong experience with cloud-native security controls in AWS, GCP, or Azure (e.g., VPC Service Controls, Private Link).
• Effective deployment of AI models and tooling to improve team productivity and execution.
• Excellent ability to communicate complex technical concepts to both executive leadership and individual contributors.

Responsibilities

• Lead the design and implementation of the Data Movement Policy (DMP) framework, ensuring it can handle complex multi-cloud and hybrid environments.
• Define the roadmap for Data Exfiltration Protection, evolve and enhance ingress and egress controls, and intelligent anomaly detection for data egress.
• Drive the technical effort to unify Context-Aware Access policies with egress perimeter controls, creating a single, cohesive policy engine for all data movement.
• Author and review complex design documents for DMP and Perimeter Policy, ensuring high reliability, low latency, and auditability.
• Partner with Product Management to refine the DXP product requirements and translate business goals into actionable engineering milestones.
• Guide senior and staff engineers across multiple teams, fostering a culture of security-first engineering and rigorous design standards.
