Job Description

As a Product Security Low-Level Researcher at Island, 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 Island’s platform. This role emphasizes deep systems knowledge, hands-on experimentation, and original research that pushes beyond application-layer security.

Job Responsibility

  • Low-Level Vulnerability Research: Research and discover vulnerabilities in operating system kernels, drivers, system services, virtualization layers, and low-level system components relevant to Island’s 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

Requirements

  • Strong understanding of operating system internals, kernel architectures, or driver development (Linux, Windows, macOS, or mobile OSes)
  • Hands-on experience with low-level programming in C/C++, Rust, or assembly
  • scripting experience (e.g., Python) for tooling and automation
  • Background in kernel vulnerability research, driver auditing, exploit development, or advanced reverse engineering
  • Deep familiarity with low-level vulnerability classes (e.g., UAF, race conditions, logic bugs, privilege escalation, sandbox and isolation bypasses)
  • Experience with kernel debuggers, fuzzers, emulation, or virtualization-based analysis frameworks
  • Strong curiosity and research mindset, with a passion for understanding systems at their lowest layers and breaking assumptions they rely on
