If you're passionate about understanding how software works at a low level, uncovering security flaws, and building impactful technical solutions, this opportunity offers the chance to work on challenging, mission-focused projects.

Required Qualifications
  • Strong software engineering experience with C, C++, Python, or Assembly.
  • Hands-on experience with reverse engineering using tools such as Ghidra, IDA Pro, Binary Ninja, or GDB.
  • Proven experience in vulnerability research, including identifying zero-day vulnerabilities, logic flaws, memory corruption issues, and other security weaknesses.
  • Experience designing, developing, or deploying solutions in cloud-native environments such as AWS, Azure, GCP, or Kubernetes.
Preferred Qualifications
  • Experience supporting operational cybersecurity or incident response activities.
  • Strong understanding of operating system internals (Windows, Linux, iOS, or Android), kernel-level debugging, and computer architecture.
  • Experience with modern DevSecOps practices, including CI/CD pipelines, Docker, containerization, and automated testing frameworks.
