Senior Security Engineer

Mixpanel is the leading product intelligence and analytics platform, trusted by more than 29,000 companies to help understand how people use the products they build. By combining powerful analytics with AI that knows your business, Mixpanel helps teams see what’s working, diagnose what’s not, and decide what to build next.

The Information Security Team at Mixpanel is a small, high-impact group committed to building a frictionless security program. We operate at the intersection of business strategy and technical execution, with a broad, generalist skill set across vulnerability management, threat detection, and access management. We strategically balance necessary compliance work with proactive initiatives, with a constant focus on automation.

• Serve as the domain expert for Detection & Response, integrating telemetry from across our entire ecosystem—including Product, Cloud, Corporate Infrastructure, and Identity—to build a unified, high-fidelity detection and response engine.
• Translate high-level project requirements and technical scoping documents into actionable milestones, managing task delivery and driving cross-functional results.
• Design and implement precise, actionable alerting within Google Security Operations (SIEM/SOAR), treating detections as code and ensuring they scale with our high-volume data ingestion.
• Develop specialized detection logic and playbooks to identify and mitigate application-layer abuses, customer account-targeted events (ATO), and sophisticated social engineering.
• Serve as the primary technical lead for security incidents during EMEA hours, driving investigations, containment efforts, and cross-functional communication.
• Evolve Mixpanel’s threat intelligence program by identifying relevant adversaries and translating tactical intel into proactive SIEM/SOAR logic.
• Ensure the operational health and telemetry flow of our core security stack—including SentinelOne, GCP Security Command Center, and Mimecast Incydr—to maintain continuous visibility and alerting integrity.

• Experience operating across the core pillars of a modern security program—including Product, Cloud, and Corporate Security. Comfortable navigating Identity (IAM), threat modeling, and secure code reviews.
• Deep understanding of the detection-as-code lifecycle, with experience turning raw telemetry into precise, actionable alerting and building the infrastructure required to defend a high-scale SaaS environment.
• Ability to manage a high volume of daily security tasks, from triaging vulnerabilities and policy violations to investigating suspicious activity across the entire stack.
• Proficiency with the Google Cloud Platform ecosystem (specifically Cloud Logging, BigQuery, and Pub/Sub) to build automated security data pipelines and maintain visibility across high-volume environments.
• Proficiency in Python to develop automated workflows and integrate security tools via APIs. Comfortable leveraging AI and LLMs to build autonomous security workflows—such as automated alert enrichment, intelligent incident summarization, and AI-assisted code analysis.

• Experience evaluating and embedding external intelligence—including dark web monitoring, brand protection, and adversary tactics—into a security program.
• Experience leading 'Security Champions' initiatives or a demonstrated ability to elevate the security IQ of non-security teams.
• Familiarity with deploying deception techniques (e.g., honeytokens, canary credentials, or 'fake' internal endpoints).
• Prior experience with enterprise-grade security tools such as Endpoint Detection & Response (EDR), Email Security gateways, and Cloud-native Security Command Centers.
• Experience defending an environment with massive, high-volume data ingestion and complex user-access patterns similar to Mixpanel’s architecture.
• Experience with vulnerability coordination platforms, automated external scanning, or managing findings from bug bounty programs.
