About The Position

Iru is an AI-powered security & IT platform that secures users, apps, and devices for fast-growing companies. It unifies identity & access, endpoint security & management, and compliance automation. The company is backed by prominent investors and recently raised $100 million, valuing it at $850 million. Iru was named to Forbes’ America’s Best Startup Employers 2025 list. The company is seeking a Security Researcher specializing in Windows and macOS threat detection to join its small, focused Threat Intelligence and Research team. This role involves researching, analyzing, and developing robust file-based and behavioral detections for malware, threat actors, and attack methodologies across both platforms. The researcher will contribute to both EDR and Vulnerability products, covering threat detection and the full vulnerability lifecycle, and will also help raise the team's external profile through published research and conference talks. The position offers significant ownership and direct impact on research and product direction.

Requirements

3–5 years of experience in cybersecurity, with hands-on focus on malware analysis and threat research across Windows and/or macOS.
Proven experience developing file-based and behavioral detections for endpoints (YARA, Sigma).
Solid understanding of the vulnerability research lifecycle: discovery through coordinated disclosure and CVE ecosystem.
Experience with malware analysis tools and techniques (Binary Ninja, WinDbg, Sysinternals, or Mac Monitor).
Strong understanding of OS internals and endpoint security mechanisms on Windows and/or macOS (Endpoint Security APIs).
Demonstrated ability to communicate research externally — blog posts, conference talks, or published work.

Nice To Haves

Experience developing or contributing to EDR or next-gen antivirus products.
Experience leveraging AI tools to accelerate threat research, detection development, and analysis workflows.
Familiarity with both Windows and macOS threat landscapes and platform-specific attack techniques.
Proficiency with security-focused scripting and data analysis (Python, PowerShell, Bash, etc.).
Demonstrated ability to assess and prioritize vulnerabilities using industry-standard frameworks and data sources (including advisories, disclosures, severity scoring, and more) with a critical eye for data quality and completeness.

Responsibilities

Perform in-depth analysis of malware and adversarial behavior across Windows and macOS to identify detection opportunities.
Develop and enhance detection rules and behavioral analytics for both platforms, integrated into our EDR product.
Collaborate with engineering teams to incorporate detection logic into our cross-platform security agent.
Actively contribute to both our EDR and vulnerability products — spanning threat detection and the full vulnerability lifecycle: discovery, product coordination,CVE publications/submissions, and public disclosure.
Research and develop new vulnerability detection methods.
Continuously monitor emerging threats and trends across Windows and macOS ecosystems.
Contribute to the product roadmap for both EDR and vulnerability products by surfacing research-driven insights and detection capability recommendations.
Author blog posts and present findings at industry conferences to contribute to the broader security community.
Document and communicate research findings clearly, both internally and externally.
