  • Cybersecurity certifications preferred: CompTIA Security+, GICSP, ISA/IEC 62443, or equivalent (or willingness to obtain).
  • Exposure to semiconductor fab automation and SCADA systems.
  • Understanding of industrial control systems (ICS), embedded security, and real-time operating systems (RTOS).
  • Familiarity with MITRE ATT&CK for ICS and threat modeling for OT environments.
  • Strong analytical, troubleshooting, and communication skills.
  • Eagerness to learn and adapt in a fast-paced environment.
