Principal Engineer I

Menlo Security’s mission is enabling the world to connect, communicate and collaborate securely without compromise. COVID-19 has made our mission all the more real. We support customers across various enterprises including Fortune 500 companies, 9/10 of the largest global banks and the Department of Defense.

The world has fundamentally changed. We are growing from 400 employees into the next phase of our journey, and we need passionate talent filled with empathy and agility. The right candidate for the job is ethical, hyper-organized, fanatical about seeing things through to completion, service-oriented, and humble enough to take feedback and coaching yet confident enough to provide feedback and coaching.

Menlo is well-funded for growth and our investors are second to none. They include Vista Equity Partners (“Vista“), General Catalyst, JPMC, American Express, HSBC, and Ericsson Ventures.

ABOUT THE ROLE

Menlo Security is seeking a Principal Software Engineer I for the R&D Policy Team. This team owns the full lifecycle of Menlo’s cybersecurity policy platform — the engine that defines how the product protects enterprise customers from web-based threats. That spans policy storage and management (authoring, versioning, and serving the rules that govern customer security posture), policy distribution (propagating policy changes reliably and at scale to enforcement points globally), and real-time enforcement (applying policies at traffic inspection time to block, isolate, or allow web activity). You will architect critical services across this stack, lead cross-functional initiatives, and help shape how the team builds software in an era where AI is a first-class engineering tool.

WHAT YOU WILL DO

• Architect, design, and own services across the policy platform — from policy storage and versioning APIs, to the distribution pipeline that propagates rule changes to enforcement nodes, to the enforcement layer that applies policies at inspection time with low latency and high availability.

• Evaluate the current state of policy management, distribution, and enforcement; design and lead a seamless modernization of the architecture that eliminates technical debt and scales for the future — without impacting customers or altering enforcement behavior.

• Lead design reviews and gain cross-functional alignment on technical direction.
