We are seeking a Principal Security Researcher to set the technical direction for a critical area of our identity protection charter, drive multi-quarter research agendas end-to-end, and raise the bar of the team through mentorship and influence. You will partner with engineering, PM, data science, and other research teams across our company to shape strategy, and you will represent our research externally through publications, talks, and industry engagement. We expect our Principal researchers to fluently leverage Generative AI and to actively shape how the team applies it - turning AI assistance into a durable force multiplier across investigation, detection authoring, and customer protection at our company scale.
our companys mission is to empower every person and every organization on the planet to achieve more. As employees we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.
Responsibilities
Set the technical direction for a major area of our identity protection research charter, owning the multi-quarter strategy from threat landscape framing to shipped detection and measurable customer protection impact.
Drive multiple concurrent end-to-end research initiatives, breaking ambiguous problems into tractable workstreams and unblocking the team on the hardest technical questions.
Lead deep investigation and research of data across identity and adjacent sources to surface novel threats, attacker tradecraft, and detection opportunities others miss.
Stay ahead of the evolving attacker landscape and design robust, sophisticated detection logics across the entire kill-chain - raising the bar on quality, coverage, and resilience to attacker evasion.
Influence across organizational boundaries - partner with product management, engineering, data science, and peer research teams to shape product strategy, define new identity protection capabilities, and align roadmaps on a data-driven foundation.
Mentor and grow other researchers, elevating the technical bar of the team through code/design review, research coaching, and apprenticeship on complex investigations.
Shape how the team and discipline leverage Generative AI - define patterns, evaluate tools, and build durable AI-assisted workflows that scale research throughput across data triage, hypothesis generation, code and KQL authoring, and detection synthesis.
Represent our company Security externally through high-quality research publications, conference talks, blog posts, and engagement with the broader security research community.

We are seeking an experienced Senior Security Researcher, excited by finding new attacks, to join our research team and focus on detecting and autonomously protecting against sophisticated enterprise attacks. The role spans novel attack-technique research, big-data analysis over rich sensor data, identifying the optics needed to expose malicious behavior, and crafting detection and protection logic so compromise does not go undetected. We expect our researchers to fluently leverage Generative AI to accelerate every stage of their work - from hypothesis generation and code prototyping to large-scale data triage and detection authoring.

Responsibilities
Own end-to-end large research projects that deliver identity protection against the most prevalent threats in the landscape, from initial threat hypothesis to shipped detection and customer protection impact.
Conduct in-depth investigation and research of data across multiple identity and additional sources to identify threats and sophisticated attack incidents.
Keep up to date with the latest trends in cyber-attacks and create robust, sophisticated detection logics across the entire kill-chain.
Collaborate with product management, security, and engineering teams across the company to design innovative solutions and new identity protection capabilities and validate their effectiveness using a data-driven approach.
Collaborate with data science teams to understand, identify, and implement detection gaps, capabilities, assumptions, and improvements.
Leverage Generative AI tooling to scale research throughput - accelerating data triage, hypothesis generation, code and KQL authoring, literature review, and the synthesis of attacker tradecraft into shippable detections.
Demonstrate thought leadership and engage and enlighten others through compelling, meaningful content and informative sessions.
