Job Summary

To support our extraordinary teams who build great products and contribute to our growth, we’re looking to add a Manufacturing Engineer located in Reynosa.

What a typical day looks like:

• Respond quickly to equipment failures; troubleshoot and restore production with minimum downtime.
• Lead and support continuous-improvement projects that increase OEE and reduce downtime.
• Diagnose and resolve abnormal issues across integrated systems — PLC, vision, robotics, motion control and smart devices.
• Carry out minor adjustments and tuning within validated lines (e.g., sensor replacement, control-logic tuning).
• Support integration changes driven by equipment obsolescence and by new smart equipment.
• Maintain and manage all production automation software in SVN (LabVIEW, Beckhoff TwinCAT, SAIA PLC) — applying and version-controlling existing software, not developing new software.
• Apply a structured root-cause approach to issues; when the root cause is a software bug, capture it clearly and provide structured feedback to the HQ PLC / control-design team.
• Troubleshoot and analyze problems to improve product quality and meet customer requirements
• Provide on-site production technical guidance and on-the-job training for production line staff.

• Advanced English.
• Clear communication in English and Spanish, including structured technical feedback to central engineering.
• Bachelor’s degree in engineering (Electrical, Mechatronics, Automation or related).
• System-level troubleshooting across PLC, vision, robotics, motion control and smart devices.
• Working knowledge of PLC platforms (Beckhoff TwinCAT, SAIA) and LabVIEW for diagnosis, tuning and minor adjustments — not new development.
• Robotics and integrated automation systems.
• Industrial protocols and networking (e.g., EtherCAT, Modbus), HMI / SCADA and motion control.
