• Preferable hands-on experience with Mitsubishi PLCs and GX Works2 / GX Works3, but not mandatory.

• Good problem-solving and debugging skills.
• Strong attention to detail and commitment to code quality and system safety.
• Good verbal communication skills and ability to work in a team-oriented environment.
