Our Team's Vision

At Illumio, we’re pioneering cybersecurity innovation with our Illumio Insights platform, which leverages a dynamic security graph built from network flows, workload inventories, identity data, threat data, and vulnerability data. This graph enables essential functions such as breach risk detection, network segmentation assessment, active breach identification, and intelligent policy recommendations. To accelerate our product evolution and establish market-leading threat intelligence capabilities, we’re building a world-class, data-driven Threat Research function.

We are seeking a hands-on Head of Threat Research to build and lead this new team from the ground up. You will serve as the long-term subject matter expert and strategic leader for the Illumio Insights product team, translating real-world threats and large-scale security datasets into actionable insights that drive product enhancements, detection logic, data enrichment, and customer risk reduction. This role starts with deep individual-contributor work and quickly expands into team-building, thought leadership, and external publishing.

This is a rare opportunity to shape a critical new function at the intersection of threat intelligence, product innovation, and security graph analytics.

Your Impact

Define the team charter, research roadmap, operating model, and success metrics focused on measurable product impact and customer risk reduction.
Design processes that transform large-scale security datasets into high-value insights, including structured feedback loops with Product, Engineering, and Security teams.
Establish quality standards, documentation practices, and research methodologies tailored to our security graph platform.
Build and track KPIs that demonstrate tangible improvements in detection efficacy, segmentation posture, and breach containment.

Hands-On Threat Research and Analysis

Personally analyze large-scale security datasets to uncover attacker behaviors, TTPs (Tactics, Techniques, and Procedures), emerging risks, and misconfigurations.
Leverage the security graph to model attack paths, recommend segmentation strategies that reduce the risk of lateral movement, and identify opportunities for stronger breach containment.
Map findings to MITRE ATT&CK and real-world adversary tradecraft; develop and validate hypotheses about evolving threats.
Create internal threat models and risk frameworks that directly inform detection logic, data enrichment, graph quality, and policy recommendations.

Product, Customer, and Strategic Impact

Partner closely with Product Management and Engineering to translate research into concrete enhancements: improved detection algorithms, data tagging, analytics, and customer-facing risk insights.
Collaborate with Customer Success, Field teams, and executives to communicate emerging threats observed in aggregate data and their implications for segmentation strategy.
Influence product roadmap decisions and help position Illumio Insights as the industry benchmark for proactive threat-informed security.

Scale and Lead the Team

Hire, mentor, and grow a high-performing Threat Research team over time.
Evolve the function from internal product-focused research into broader external thought leadership (publications, conference talks, industry reports).
Foster a culture of curiosity, rigor, and impact-driven research.

Your Toolkit

10+ years of experience in threat research, detection engineering, incident response, or threat intelligence, with a proven track record of hands-on technical work.
Prior experience as a manager or senior individual contributor who has successfully built or scaled a threat research capability from scratch.
Deep expertise in attacker tradecraft, real-world TTP mapping (MITRE ATT&CK), IOC analysis, and incident response processes.
Strong experience working directly with Product and Engineering teams in a security product company or vendor environment.
Demonstrated ability to analyze security telemetry and translate complex findings into product improvements and business-relevant insights.
Excellent written and verbal communication skills, including executive briefing experience.

Preferred Qualifications

Background in graph-based analytics, security graphs, or network segmentation/zero-trust environments.
Hands-on experience with large-scale telemetry analysis and detection engineering.
Familiarity with data science or ML techniques applied to threat detection. Track record of publishing threat research or speaking at industry conferences.

Bonus Points

Previous leadership role at a cybersecurity product company (endpoint, network security, or analytics-focused vendor).
Experience integrating external threat intelligence and vulnerability data into product features.
Public thought leadership portfolio (blogs, reports, talks, or open-source contributions).

Who You Are

A researcher at heart who thrives on diving into raw data to uncover hidden patterns and real-world attacker behaviors.
A pragmatic builder who can deliver immediate product value while simultaneously designing a scalable, world-class function.
Equally comfortable in deep technical analysis and high-level executive or customer conversations.
A collaborative leader excited to turn cutting-edge threat research into measurable product differentiation and customer protection.
Passionate about bridging real-world threats with innovative security graph technology to stay ahead of adversaries.
