We are looking for a Security Researcher who thrives on both sides of the fence. You will develop offensive tradecraft-discovering new attack vectors and writing exploits-then use that perspective to engineer robust, product-level mitigations. If youre energized by finding a novel browser attack on Monday and shipping the defense for it by Friday, this role is for you.

Key Responsibilities

Offensive Research: Discover new attack vectors, abuse patterns, and security gaps in browsers, web applications, OS internals, and enterprise workflows.
Defensive Engineering: Design and implement detections, mitigations, and security policies informed by your offensive findings; close the loop from attack to protection.
Vulnerability & Malware Analysis: Perform reverse engineering on malware, exploits, and obfuscated code across Windows, macOS, and browser environments.
Web & Browser Security: Research techniques ranging from classic vulnerabilities (XSS, SSRF) to browser-specific primitives (extension abuse, DOM manipulation, same-origin bypasses).
Supply-Chain Security: Investigate threats in software supply chains, including browser extension marketplaces and package registries.
Threat Intelligence: Correlate signals across multiple sources to identify malicious infrastructure and adversary TTPs.
Public Impact: Write technical blog posts, publish research, and represent at major security conferences (Black Hat, DEF CON, etc.).

As a Product Security Researcher , you will dive deep into the security landscape of modern browsers, operating systems, and enterprise applications to discover novel vulnerabilities, evaluate real-world threat scenarios, and help shape our security posture through innovation and hands-on research. You will be instrumental in driving advanced security initiatives that help maintain position at the cutting edge of secure enterprise computing.

Key Responsibilities:

Vulnerability Research: Identify and analyze vulnerabilities in browser components, system integrations, and third-party libraries relevant to the Enterprise Browser.
Security Testing & Tooling: Develop custom tooling and automation for security testing, fuzzing, and vulnerability detection tailored to our product stack.
Threat Modeling: Collaborate with developers, architects, and the Product Security Lead to assess threat scenarios and attack surfaces for new features and integrations.
Exploit Prototyping: Build proof-of-concepts to validate the impact and exploitability of discovered security issues.
Collaboration & Knowledge Sharing: Support development teams in secure coding practices, and contribute to internal knowledge bases and playbooks.
Security Research Enablement: Stay ahead of the curve by tracking current exploits, security trends, and techniques; attend or present at security conferences and engage with the broader security community.

As a Product Security Low-Level Researcher , you will focus on deep technical research across operating systems, kernels, drivers, and low-level system components that underpin modern enterprise computing. You will investigate complex attack surfaces, uncover subtle and high-impact vulnerabilities, and translate cutting-edge research into practical security improvements for platform. This role emphasizes deep systems knowledge, hands-on experimentation, and original research that pushes beyond application-layer security.



Key Responsibilities:

Low-Level Vulnerability Research: Research and discover vulnerabilities in operating system kernels, drivers, system services, virtualization layers, and low-level system components relevant to execution and trust boundaries.
Kernel & OS Internals Analysis: Analyze kernel subsystems (memory management, scheduling, IPC, filesystems, networking) and OS security primitives to identify design flaws, logic bugs, and exploitation opportunities.
Exploit Development & Validation: Develop proof-of-concept exploits for kernel- and driver-level issues to validate impact, assess exploitability, and inform mitigation strategies.
Security Testing & Tooling: Design and build custom tooling for kernel fuzzing, syscall/interface testing, driver analysis, and low-level instrumentation across supported platforms.
Cryptography & Trust Mechanisms: Assess the implementation and usage of cryptographic primitives, key management, secure boot, attestation, and hardware-backed security features, identifying weaknesses or misuse patterns.
Threat Modeling at the System Level: Collaborate with architects, platform engineers, and the Product Security Lead to model threats across privilege boundaries, boot chains, isolation mechanisms, and OS-level integrations.
Research Enablement & Knowledge Sharing: Track emerging exploitation techniques, kernel research, and advanced persistent threat tradecraft; contribute findings to internal playbooks, design guidance, and long-term security strategy.
