Nagomi Security · Tel Aviv-Yafo

Description About Nagomi Security teams are not short on tools. They are short on time, alignment, and the ability to actually close exposure. That's why most breaches could have been prevented with a tool that was already in use. Nagomi was built to change that. We are the first Agentic Exposure Ops Platform, designed to prevent the preventable breach by turning fragmented signals into coordinated action. Our agents investigate risk, drive remediation, and verify that issues stay closed, continuously, without adding overhead. Nagomi is helping organizations move from reactive workflows to continuous execution, replacing manual effort with systems that actually move the work forward. The Opportunity As a Senior Security Researcher, you will bridge our core research initiatives at the intersection of proactive exposure management, agentic workflows, and scalable threat modeling. We are looking for an innovator who translates complex security data into product-driven features, taking full ownership from concept to production. What You'll Do • Drive Product-Led Research: Translate complex, real-world security challenges into actionable, product-driven research. Take full ownership of research projects end-to-end, from identifying the security gap to collaborating with engineering to ship platform features. • Drive Proactive Exposure Management: Leverage Automated Security Control Assessments (ASCA) alongside vulnerability evaluation and prioritization to holistically assess organizational risk. Deep dive into enterprise security tools (EDR, SIEM, Firewalls, IAM, etc.) to analyze configurations, map defensive capabilities, and continuously evaluate their effectiveness against real-world threats. • Build Security Tool Integrations: Drive the technical research and define the data models required to actually build deep, functional integrations into diverse security platforms, ensuring the accurate extraction of telemetry, policies, and configuration data. • Build AI & Agentic Workflows: Define, design, and implement the logic and knowledge base that feeds Nagomi's AI-powered agents, ensuring they deliver accurate, context-aware security guidance and automated risk assessments. • Map Attack Paths: Define realistic attack flows, identify toxic combinations of misconfigurations, and surface the security gaps that help customers prioritize the risks that actually matter. • Engage with Customers: Work directly with customers to help them understand their exposure, translate your research findings into meaningful posture improvements, and gather feedback to drive product innovation. • Cross-Functional Collaboration: Partner closely with product, engineering, and data teams to embed security insights into everything we build. Requirements • Experience: 5+ years of hands-on experience in cybersecurity research, exposure management, vulnerability analysis, or threat intelligence. • Product Mindset: Strong ability to tackle projects end-to-end, translating theoretical security research into tangible product features and automated detection logic. • Broad Security Knowledge: Deep understanding of enterprise security tools (EDR, NDR, SIEM, VM, etc.), network topology, and how security components interact to impact network posture. • AI/Agentic Expertise: Proven experience building or heavily shaping AI-powered systems and agentic workflows.

Principal Cloud Security Researcher
Mitiga · Tel Aviv-Yafo

Description We’re looking for Principal Cloud Security Researcher with a strong security background to join our innovative Research team. Why Mitiga? EDR protects the endpoint. Mitiga protects everything else, anticipating and disrupting active attacks across the modern stack and stopping them before they reach the business. Mitiga is the leader in Zero-Impact Breach Prevention, delivered through Agentic Runtime Security for the modern infrastructure — cloud, SaaS, identity, and AI. By delivering the runtime detection and response that security teams already rely on for endpoints, extended to the infrastructure endpoint tools can’t see, Mitiga provides Zero-Impact Breach Prevention, in runtime. The Role We're looking for a Principal Cloud Security Researcher to serve as a senior technical leader within our Research team. This is a high-impact individual contributor role -- you won't manage people, but you'll shape the direction of our entire research function, mentor researchers, and act as a force multiplier across the organization. You'll be the person who takes a vague threat signal and turns it into a detection strategy, a published finding, or a product capability. You'll operate as a trusted deputy to the research team lead, owning the most complex and ambiguous research challenges while raising the technical bar for the team. What You'll Do Drive Groundbreaking Research • Own and drive Mitiga's most critical research initiatives end-to-end - from initial threat hypothesis through detection logic, product integration, and external publication. • Set the technical direction for cloud threat research across AWS, Azure, and GCP, identifying emerging attack surfaces and novel techniques before they become mainstream threats. • Investigate real-world cloud and SaaS security incidents, dissecting attacker tradecraft and extracting insights that evolve our detection capabilities. • Pioneer new forensic investigation techniques and detection methodologies for cloud-native and SaaS environments - pushing the state of the art, not just following it. Be a Voice in the Community • Represent Mitiga as a thought leader through high-quality research publications, conference presentations (BlackHat, DEF CON, RSA, fwd:cloudsec, and similar venues), and open-source contributions. • Build and maintain Mitiga's reputation as a research-driven company that advances the field - not just a vendor with a blog. • Engage with the broader security research community, fostering relationships and collaborative knowledge-sharing. Shape the Product • Bridge research and product - translate threat findings into actionable product requirements, working closely with engineering and product teams to ensure our CDR platform stays ahead of evolving threats. • Design and develop advanced detection algorithms that directly feed into Mitiga's platform, closing the gap between research insight and customer protection. Elevate the Team • Act as the team's go-to technical authority. When researchers hit a wall on complex cloud attack chains, IAM edge cases, or detection gaps - you're who they turn to. • Mentor and grow other researchers through research reviews, pair investigations, code reviews, and by setting quality standards and methodology best practices. • Influence technical decisions org-wide - contributing to architecture, tooling, and strategic research priorities. • Step in as the research team lead's deputy when needed - driving prioritization, representing research cross-functionally, and ensuring continuity. Requirements Who You Are • 8+ years in security research, threat research, or closely related fields (offensive security, detection engineering, incident response, cloud security engineering). Fewer years are fine if your depth and track record are exceptional. • Deep multi-cloud expertise - strong hands-on experience across at least two of the major cloud providers (AWS, Azure, GCP), with working knowledge of the third. You understand the IAM models, logging pipelines, APIs, and attack surfaces that matter in each. • A track record of original research - you've published meaningful technical findings through blog posts, conference talks, open-source tools, or vulnerability discoveries that moved the needle. We want someone who doesn't just consume research - you produce it. • Strong adversarial mindset and critical thinking - you think like an attacker targeting cloud infrastructure, SaaS platforms, identity systems, and Kubernetes. You can model threat scenarios, map out attack paths, and poke holes in defenses. • Ability to operate autonomously on ambiguous, high-stakes problems. You don't wait for detailed specs - you identify what matters and drive it forward. It Would Be Nice If You Also Had • Experience with cloud forensics and incident response (DFIR in cloud/SaaS environments). • Background in red teaming or penetration testing targeting cloud environments. • Familiarity with Kubernetes security, container escape techniques, and cloud-native supply chain risks. • Experience building or contributing to threat intelligence frameworks or detection content libraries. Some More Details and Perks • Location: Tel Aviv, IL • Hybrid work Environment • Competitive compensation package with stock options, educational fund, cibus. • Top of the line equipment For more information visit us at www.mitiga.io Mitiga is an equal opportunity employer, committed to diversity and inclusiveness and aim to attract, retain, and engage a diverse workforce.

Job Description The Exposure Management Research Group at Check Point Software Technologies is expanding. We are looking for an experienced Offensive Security Researcher to join our newly formed AEV Team and lead the offensive side of our Agentic Exposure Validation (AEV) research. About the group: The Exposure Management Research Group is the research arm behind Check Point's Exposure Management platform. The platform helps organizations see and reduce their risk from the outside in, across their external attack surface, threat intelligence, and digital risk. The group brings together vulnerability researchers, threat intelligence analysts, phishing researchers, and data scientists. Together, we track threat actors and campaigns, analyze vulnerabilities and active exploitation, and turn that research into detections, intelligence, and validation capabilities that serve thousands of customers worldwide. Our work relies heavily on data science, machine learning, and agentic AI to operate at scale. About the position: Exposure validation goes beyond identifying that a vulnerability exists. Its purpose is to show whether an attacker could actually exploit that vulnerability, and how far they could get. In this position, you are responsible for bringing real offensive expertise into our AEV capability, which runs on an agentic AI system that validates exposures across our customers' environments. You conduct hands-on offensive research, define the exploitation methodologies the system follows, and set the standard for what a validated, customer-ready finding looks like. You also work closely with our threat intelligence and detection teams, so that proven attack paths turn into protections for our customers. This is a research position with direct product impact. It combines practical red team work with shaping how an AI-driven platform conducts, reasons about, and reports offensive activity. What you'll do: • Design and run offensive research against external attack surfaces: web applications, APIs, cloud-exposed services, identity, and edge infrastructure • Turn single findings into demonstrated impact through exploit chaining, lateral movement, and blast-radius analysis • Write and maintain the exploitation methodologies and attack hypotheses our agentic AEV engine runs on • Review agent runs and findings. Separate proven impact from claimed impact, and turn the gaps you find into better prompts, methods, and guardrails • Set the bar for customer-ready findings: a clear impact story, a reproducible chain, and remediation guidance a security team can act on • Work with threat intelligence researchers to turn in-the-wild attacker behavior (named actors, active campaigns, newly exploited vulnerabilities) into validation plays • Help close the purple loop by turning proven attack paths into detection and protection logic, and working with detection engineering on coverage • Contribute to the team's research output, including internal knowledge sharing and, where it fits, external publications and talks Qualifications • 2+ years of hands-on offensive security experience: red teaming, penetration testing, or offensive research • Real exploitation depth beyond confirming vulnerabilities, including exploit chaining, privilege escalation, lateral movement, and showing business impact • Comfort with the non-deterministic side of offense: business logic flaws, misconfigurations, credential and token abuse, and using information disclosure as an entry point • Strong scripting and automation skills (Python preferred) • Clear written communication. You can explain a complex attack chain to an engineer and to a CISO Strong advantage • A consulting background covering many customer environments, not one internal estate. You know what customers value in an engagement deliverable and how to present it • Broad exposure to defensive technologies, security controls, and vendors, and an understanding of what attacks look like from the defender's side • Experience with template-based or automated scanning frameworks (for example, Nuclei) • Detection engineering experience (Snort/Suricata, YARA, SIEM detection logic) • Experience working with large language models (LLMs) or agentic AI workflows, or a strong interest in shaping how AI systems do offensive work Nice to have • Offensive certifications (OSCP, OSEP, OSWE, CRTO, or similar), public CVEs, conference talks, or published research Additional Information Why join us • Impact at scale. A technique you capture once runs across thousands of customer environments • A new category. Agentic exposure validation is being defined right now, and you help define it • A strong research bench.
