Job Description:

Notion is looking for a talented Security Engineer with solid communication and analytical skills to help us improve and optimize our security monitoring program. We are seeking someone with a mixture of technical ability, attention to detail, and who can function comfortably in a variety of cyber security disciplines. In addition to technical acumen and enthusiasm, we need a self-motivator to stay on top of emerging threats and vulnerabilities to Notion; providing a continuous proactive monitoring approach.

Job Responsibility:

  • Design and implement advanced detections, automate security workflows, lead incident investigations, and conduct proactive threat hunts to identify and mitigate risks before they impact Notion
  • Lead detection engineering efforts, designing scalable, high-fidelity security detections across cloud, endpoint, and application environments
  • Develop automation & orchestration solutions to improve response and containment times and enhance security workflows
  • Own and drive incident response and command, leading major security incidents, containment, and remediation efforts
  • Conduct proactive threat hunting, leveraging threat intelligence and hypothesis-driven methodologies to detect hidden adversary activity
  • Reverse-engineer attacks, analyzing adversary behavior and developing robust detection strategies
  • Continuously improve security defenses, applying lessons learned from incidents, hunting exercises, and emerging threat trends

Requirements:

  • 5+ years of experience in security detection, response, or related fields
  • Strong ability to write, tune, and optimize detections across various platforms (e.g., EDR, SIEM, network monitoring)
  • Proficiency in scripting and automation (Python, Go, or similar) to enhance detection and response capabilities
  • Experience with detection rule development (Sigma, YARA, Splunk SPL, KQL) and security event correlation
  • Deep expertise in the incident response lifecycle, including investigation, containment, remediation, and recovery
  • Lead security incidents and command response efforts, ensuring rapid containment and mitigation—even in unfamiliar environments and across team boundaries
  • Lead post-incident learning, conducting blameless postmortems and driving follow-up actions that address systemic issues and prevent recurrence
  • Experience securing cloud-native environments (AWS, GCP, or Azure), including detection and response strategies for cloud workloads
  • Practical knowledge of detecting malicious activity in application and infrastructure architectures in a SaaS environment
  • Ability to assess security gaps and propose detection & response improvements across cloud and endpoint platforms
  • Pragmatic and business-oriented: You focus on high-impact security efforts, balancing security investments with real-world risk
  • Not ideological about technology: You see technologies and programming languages as tools with tradeoffs—you’re opinionated but adaptable, always willing to learn new technologies
  • Empathetic communication: You clearly articulate complex security issues, whether in technical discussions or executive briefings. You engage thoughtfully in disagreements and find common ground when needed
  • Team player: You thrive in a team environment, collaborating cross-functionally to accomplish shared security goals. You care about mentorship, learning, and continuous improvement

Nice to have:

  • Experience leading large-scale security initiatives or driving security automation programs
  • Background in red teaming, adversary emulation, or offensive security
  • Familiarity with application-level detections, such as database security monitoring, detecting malicious queries, or abnormal application behavior
  • Familiarity with security compliance standards (SOC 2, ISO 27001), though not a primary focus
  • Involvement in the security community, such as conference presentations or open-source contributions
