Full job description

MongoDB's Global Security Organization (GSO) is looking for a Principal Security Engineer. The GSO secures MongoDB's products, infrastructure, and the trust our customers place in us — spanning product security, corporate security, and risk, and working across engineering, go-to-market, and corporate development to keep security moving at the same speed as the business.

The Principal Security Engineer will serve as a senior technical anchor for the team. This is a deep individual-contributor role that will stay hands-on with hard security and architecture problems, form sharp independent opinions, and know how to debate, align, and commit once GSO has made a call.

Key topic areas will include collaborating with our product teams to ensure identity and permission models meet customer needs for our new autonomous agent platform and working with integration security teams to push the envelope on automated detection, reproduction, and remediation of security vulnerabilities via AI. What we need here is depth, judgment, and the ability to build up the bench of senior technical talent around you.

This role can be based out of our NYC or Seattle office or remotely in the North America region.

Responsibilities

Maintain real technical depth in security and in MongoDB's product architecture — compute, network, and storage — deep enough to evaluate actual risk rather than apply generic best practice
Form independent, well-reasoned opinions on security and architecture decisions, and voice them even when they cut against consensus or a leader's default plan
Push teams to move faster when process or over-engineering is introducing complexity without reducing risk — and push teams to slow down when GTM pressure is outrunning a clear-eyed view of the risk
Debate hard, then align, then commit: help the org land on the right call, then execute on it
Seed and grow a working community of senior ICs embedded in security operations, product security, and enterprise security — connecting people, sharing knowledge, and creating the venues (formal or informal) for that to happen
Lead time-boxed, high-stakes, cross-functional engagements such as M&A security due diligence and partner risk assessments, often with incomplete information and a short runway
Draw on your own expertise where it applies, and quickly figure out how to close knowledge gaps elsewhere — staying accountable for the outcome either way

Requirements

12+ years of experience in security engineering, software engineering, or a related discipline, including senior individual-contributor or technical-lead experience
