You will focus on identifying and mitigating identity-related threats across networks, endpoints, and cloud environments, using statistical classification methods to build effective detection models and protecting customers at scale. Additionally, you will collaborate with cross-functional teams, validate detection concepts on real-world data, and continuously enhance detection capabilities to stay ahead of emerging threats.
Key Responsibilities
Research innovative methods for detecting targeted attackers operating in endpoints, networks, cloud and SAAS environments.
Simulate real-world attacks in lab environments and conduct a deep analysis of the behavior.
Develop and refine statistics-based classification algorithms and techniques to create and improve detection models.
Research specific scenarios to enhance our model's capabilities.
Collaborate within a diverse research group, improving our research processes and leading us to be a better team creating a better product.
Stay informed on the latest APTs, attacker methodologies, and TTPs to ensure our models stay ahead of emerging threats.

We're looking for a Security Researcher to join our team at the intersection of security research, AI, and product. This isn't a traditional research role - you'll be deeply embedded in how the platform is built, working side by side with R&D, Product, and AI teams to make sure security expertise is baked into every layer of what we ship. You'll own detection and analytics research across cloud, identity, endpoint, and beyond, while actively shaping how AI capabilities are applied to solve real security problems at scale.





WHAT YOU WILL DO

Research and develop sophisticated detections and behavioral analytics across multiple security landscapes - cloud, identity, endpoint, network, and application - with a focus on coverage that scales across customer environments.
Work closely with R&D, Product, and AI teams as the security authority - reviewing features, shaping designs, and ensuring security logic is sound, practical, and impactful.
Apply an AI-native approach to detection and analytics challenges - leveraging LLMs, ML signals, and AI-assisted workflows to do things that rule-based approaches can't.
Identify gaps in detection coverage and analytical capabilities, and drive those findings directly into the product roadmap.
Analyze real-world attacker techniques and translate them into detection logic, hunting content, and analytical frameworks that ship as part of the platform.
Evaluate detection quality rigorously - measuring fidelity, coverage, and performance against real attacker behavior and production telemetry.
Stay sharp on the evolving threat landscape and rapidly incorporate new techniques, campaigns, and attacker tooling into our detection library.
Contribute to external research output - blog posts, talks, open-source tooling - that reflects our depth and point of view in the security community.

As an AI Security Researcher , you will play a key role in shaping the future of modern runtime AI security. You will investigate how real-world attacks unfold across AI-enabled applications, agents, tools, executed in cloud environments, and turn those insights into innovative, production-grade security capabilities across our AI Security Posture Management (AI-SPM) and AI Detection & Response (AI-DR) products.

This role is ideal for a deeply technical researcher who is driven to understand AI attacks at their core - not just identify suspicious prompts or surface-level indicators. You will research how prompt injection, tool misuse, agent drift, model abuse, and other emerging AI attack techniques translate into real runtime behavior and security impact. You will then apply that knowledge to build protections that are precise, resilient, scalable, and grounded in how attacks actually work in production.

Specifically, you will:

Research real-world attacks targeting models, agents, MCP/tooling ecosystems, RAG applications, and AI-enabled production systems.
Drive research end-to-end - explore, design, develop, validate, and deploy detection logic and protections based on runtime telemetry, exploit PoCs, technical analysis, and threat intelligence.
Shape AI-SPM capabilities by identifying what telemetry, signals, and modeling are required to continuously discover AI components, classify AI behavior, map risk, and detect unsafe or anomalous usage in production.
Shape AI-DR capabilities by researching how to detect AI-driven attacks, prove runtime impact, establish causality, and distinguish failed attempts from real compromise.
Work closely with engineering and product teams to turn deep technical research into practical security capabilities that deliver clear customer value.

We're building something special in our Israel-based Offensive Security organization, and we're hiring multiple people across three key areas:
Penetration Testing
Red Team Product
Security Research
While these roles share a common foundation in offensive security tradecraft, each brings its own unique focus and impact.
We're looking for deep expertise in at least one of these areas, with the ability to grow across others. We have multiple openings and are looking for talent at various levels. As we get to know you through the interview process, we'll work together to identify the best fit matching your expertise and interests with the specific role and level (Senior, Lead, or Principal) that makes the most sense for both you and the team.
Role Overview
We are seeking a highly skilled offensive security professional to join our elite team. This role is ideal for someone who thrives on breaking systems, finding creative attack paths, and using their findings to drive meaningful security improvements across our company's products and infrastructure.
You will work alongside some of the best minds in security, operating with significant autonomy and impact. Whether you specialize in deep application level penetration testing, red teaming, security research or vulnerability discovery, we want to hear from you-you don't need to be an expert in all three domains. What unites these roles is a relentless attacker mindset, a drive to find and demonstrate real-world impact, and the ability to translate offensive findings into lasting security improvements.
Responsibilities
Conduct advanced penetration testing, red team operations, or security research targeting our company's cloud infrastructure, applications, and services
Discover, exploit, and document security vulnerabilities using creative and methodical approaches
Develop custom tools, exploits, and attack techniques to simulate real-world adversaries
Collaborate with product teams to remediate vulnerabilities and improve secure design practices
Contribute to the maturity of our offensive security program through automation, tooling, and process improvements
Mentor and share knowledge with team members, fostering a culture of continuous learning
Present findings and security insights to technical and executive audiences
Stay ahead of emerging threats, attack techniques, and offensive security tradecraft.

We're looking for a research-minded, DevOps-fluent Security Researcher to own the "left" side of the platform - from source code and IaC, through CI/CD pipelines, into running cloud workloads and the sensitive data they touch. You'll trace how risk originates in a commit or a data store and follows an attack path all the way to runtime, then turn that research into the posture logic that powers our code-to-cloud, CSPM and DSPM capabilities. This role sits at the intersection of DevSecOps, cloud, data security, and AI systems.
Conduct deep technical research across the full software development lifecycle - source code, IaC, dependencies, CI/CD pipelines, artifacts, and runtime - to map the environment and discover novel risks, misconfigurations, and end-to-end attack paths (code-to-cloud), then enrich findings with context and generate meaningful, actionable remediation.
Lead research into Data Security Posture Management (DSPM): how sensitive data is stored, classified, moves, and gets exposed across cloud data stores, and translate this into data discovery, classification, and data-flow risk logic.
Correlate runtime context from our eBPF sensors with code, pipeline, and data findings to prioritize what is actually reachable and exploitable - not just theoretically vulnerable.
Research and apply AI and ML techniques to strengthen the policy engine itself - improving detection accuracy and coverage, reducing false positives, and making risk prioritization and analytics smarter across code, cloud, data, and runtime signals.
Lead product initiatives from inception to production. Collaborate closely with product, backend, and GTM, translating research into shipped product capabilities.
Define and build complex policy and risk-prioritization logic spanning code, cloud, data, and runtime.

Were seeking a Senior Security Researcher to drive end-to-end research initiatives that strengthen detection capabilities. In this role, youll investigate emerging attack surfaces, craft and implement innovative detection logic, and test your findings in real-world environments. Its a hands-on position ideal for someone eager to transform research insights into effective, production-grade security defenses.
Responsibilities:
Research AI Agent and LLM-related risks, such as prompt injection and jailbreaking and implement sophisticated detection strategies.
Conduct research on cloud, web, and API security to uncover new threats and attack vectors.
Develop, refine, and design world-class detection logic and rules to enhance runtime protection.
Perform threat-hunting activities across large data sources to identify emerging attack patterns
Drive full-cycle research: from hypothesis and experimentation to production validation.
Collaborate with engineering and product teams to deliver actionable insights.

We're hiring a Senior Security Researcher to be the security authority behind our AI agents, and the person who decides what "good" means. As our agents take on more of the security workflow, the hardest question stops being "can we build it?" and becomes "is the agent actually right?" Answering that takes someone who understands how vulnerabilities are found, exploited, and remediated at a deep level, and who can turn that judgment into rigorous, repeatable benchmarks the whole team builds against. You'll own those benchmarks. You'll encode your security expertise directly into the agents - the guidelines, heuristics, and domain knowledge they reason with, and guide how they improve over time. You'll help us understand the real complexity behind the features we want to build, and break them into deliverable pieces. And you'll do it with a genuine appetite for experimental AI - comfortable getting your hands dirty with frontier models and agent tooling, not intimidated by it.
What you'll do:
Own our benchmarks and evaluations. Define what "correct" and "high quality" mean for AI agents that detect, prioritize, and remediate security issues. Build and maintain the benchmark datasets, scoring methods, and ground truth that the team measures itself against - and keep raising the bar.
Guide how our agents get better. Dig into where agents fail - false positives and negatives, bad or unsafe fixes, missed exploitability, wrong prioritization - and translate that into concrete improvements to prompts, tools, data, and agent design alongside engineers.
Be the security ground truth. Bring deep, hands-on AppSec judgment to bear on agent outputs: threat-model the edge cases, label the hard examples, and think adversarially about where an autonomous security agent could be confidently wrong.
Scope and decompose new features. Assess the security complexity and feasibility of new capabilities we want to build, explain the risks and trade-offs clearly, and help break ambiguous, research-heavy problems into small, shippable deliverables.
Be our early adopter of experimental AI. Stay on the frontier of models, agent techniques, and tooling. Test what's new, figure out what's real, and bring the useful parts back into the team.
