Fuzzing Developer

I’m hiring for a company developing advanced security research technologies, with a strong focus on automated vulnerability discovery in complex environments.

This is a hands-on Fuzzing Engineer role, focused on building and evolving systems that identify security vulnerabilities across operating systems and browsers.

The role combines low-level development, vulnerability research, crash analysis, debugging, reverse engineering, and automation at scale.

What you’ll do:

Design and develop fuzzing engines for complex systems, mainly OS and browsers

Investigate vulnerabilities with a focus on memory-related issues, including crashes, corruption, and related behaviors

Perform crash triage and root-cause analysis

Use debuggers and reverse engineering tools to analyze system behavior

Build automation and infrastructure to support large-scale security research

Collaborate closely with research and development teams across the organization

What you need?

3+ years of hands-on low-level development experience

Familiarity with operating systems, OS internals, or browsers

At least 2 years of strong Python development, beyond scripting

Proven experience with system-level development and technical problem-solving, such as debugging complex issues, building internal tools, or analyzing system behavior

Experience with debugging tools such as WinDbg, gdb, lldb, or similar tools

This role is a strong fit for someone who enjoys deep technical research, understands how complex systems behave under the hood, and wants to build tools that directly support vulnerability discovery.
