Industrial Electrical, Instrumentation & PLC Automation Design Engineer

About CHAMPOIL

CHAMPOIL is a manufacturing company focused on lubricant and industrial chemical products, committed to reducing waste through innovative, sustainable, reliable, and economically viable solutions.

For us, engineering innovation is not simply about implementing new technology. It must create systems that are safer, more precise, easier to maintain, generate less waste, and are better prepared to support the company's growth.

As our manufacturing operations continue to grow, we are looking for an engineer who can translate production requirements into reliable, safe, maintainable, and scalable electrical, instrumentation, automation, and manufacturing systems.

Role Overview

This role is responsible for translating production process requirements into electrical, instrumentation, PLC automation, MEP, and technical drawing solutions that are safe, buildable, maintainable, and scalable.

The position combines engineering design capability with hands-on technical execution in the field. The role will be involved from process requirement mapping, engineering design, technical drawing, control architecture, cross-system coordination, custom machinery development, installation, commissioning, troubleshooting, through to engineering documentation and standardization.

The successful candidate is expected not only to troubleshoot machines when faults occur, but also to design systems that prevent errors, clashes, downtime, rework, and excessive dependency on individual knowledge.

Filling Machine & Production Line Engineering

• Develop filling systems appropriate for lubricant and chemical product characteristics, including viscosity, foaming, dripping, temperature sensitivity, and filling accuracy requirements.

• Optimize synchronization between filling nozzles, pumps, valves, conveyors, bottle detection, capping, labeling, weighing, and rejection mechanisms.

• Analyze underfill, overfill, dripping, product carryover, unstable flow, bottle jams, false detection, and cycle time losses.

• Adjust control logic, mechanical movement, sensor positioning, pneumatic timing, and filling parameters to improve production stability.

• Develop changeover systems and recipe management for different packaging sizes, product types, and target volumes.

• Ensure production lines have appropriate buffer logic and machine handshakes so that disruption in one machine does not unnecessarily stop the entire line.

Technical Drawing & Engineering Detailing

• Translate operational requirements and layouts into technical drawings including plans, elevations, sections, details, and installation drawings.

• Define dimensions, scale, tolerance, clearance, mounting details, routing, connection points, and installation methods clearly.

• Develop details for machine bases, platforms, supports, piping routes, cable trays, panel positions, utility points, fixtures, guards, and maintenance access.

• Ensure drawings contain sufficient information for fabricators, contractors, panel builders, and installation teams to execute without different interpretations.

• Develop standard drawing templates, symbol libraries, title blocks, numbering systems, revision histories, and document registers.

• Maintain drawing repositories and version control to ensure teams always work from the latest approved documents.

MEP & Cross-System Coordination

• Integrate mechanical, electrical, plumbing, piping, drainage, compressed air, ventilation, utilities, structures, and equipment requirements into coordinated designs.

• Ensure power, water, drainage, air pressure, exhaust, access, and service points are available at the correct locations.

• Conduct clash detection involving equipment, structures, piping, cable trays, ducting, panels, platforms, and access routes.
