About the role

Senior technical anchor and individual-contributor in MongoDB's Global Security Organization. Focus on security across product, infrastructure, and risk; collaborate with product teams on identity/permission models and with integration security teams to advance automated detection, reproduction, and remediation of vulnerabilities using AI.

Responsibilities

  • Maintain real technical depth in security and 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

Qualifications

  • 12+ years of experience in security engineering, software engineering, or a related discipline, including senior individual-contributor or technical-lead experience
  • Bachelor's degree in Computer Science, Information Security, or a related field, or equivalent practical experience
  • Deep, credible technical expertise in security, plus working depth across compute, network, and storage architecture
  • A track record of forming and defending independent technical positions, along with the judgment to know when to stop debating and commit
  • Experience influencing without formal authority, including with management and cross-functional partners, in both directions — accelerating and slowing down decisions
  • Comfort owning ambiguous, deadline-driven work such as M&A diligence or partner risk reviews, and being accountable for the result even without the full picture upfront
  • A genuine interest in mentoring and connecting other senior engineers, without needing a management title to do it
