Position purpose
The company is seeking a qualified and practically orientated Electrical Engineer to assist with the electrical design, control panel manufacturing, PLC programming, testing, commissioning and technical support of its industrial machinery.
This is a hands on engineering position. The successful candidate must be willing and able to work in both an engineering design environment and on the factory floor.
The role is suited to an electrical or mechatronic engineering graduate with practical automation experience and a strong interest in industrial machinery. The successful candidate will work closely with our engineering, manufacturing and technical teams while developing toward independent responsibility for electrical control systems.
The objective of the position is to improve the standardisation, documentation, reliability, safety and technical support of all machinery.

- Read and interpret electrical schematics during panel construction.
- Inspect panels for workmanship, correctness and serviceability.
- Test completed panels before installation on machinery.
- Assist with developing standard panel layouts and wiring practices for machines.
The successful candidate must be willing to manufacture and wire control panels personally and may not treat panel building as an artisan-only responsibility.
3. PLC and HMI programming
- Develop and modify PLC programs.
- Develop HMI screens, alarms, operating parameters and diagnostic information.
- Configure PLC inputs and outputs.
- Program automatic, manual and maintenance operating modes.
- Incorporate sensors, limit switches, pressure switches, solenoid valves and motor controls into the PLC sequence.

- Document changes identified during prototype development.
- Ensure that approved changes are incorporated into the drawings, programs and final machine.
5. Testing and commissioning
- Conduct input/output checks.
- Test motors, contactors, overloads, drives, sensors, switches, actuators and solenoids.
- Test automatic and manual machine sequences.
- Verify alarms, emergency stops, safety switches and interlocks.
- Assist with continuity, insulation resistance and earth continuity testing.
- Identify and correct wiring, programming and component faults.
- Assist with factory acceptance testing.
- Commission standard machinery at the factory.
- Assist with commissioning at customer sites when required.
- Prepare testing and commissioning records.
- Obtain appropriate technical approval before machinery is released.
6. Electrical safety and standards
- Apply approved electrical design and panel building standards.
- Develop practical knowledge of applicable South African and international standards, including:
- SANS/IEC 60204-1 for electrical equipment of machines
- SANS/IEC 61439, where applicable
- SANS 10142-1, where relevant
- IEC 61131-3 PLC programming principles
- Applicable Occupational Health and Safety requirements
- Applicable Electrical Machinery and Driven Machinery Regulations
- Assist with machine risk assessments.
- Ensure suitable isolation, protection, earthing, emergency stopping and interlocking.
- Escalate safety, compliance or design matters that fall outside the employee’s level of competence.
- Identify work requiring review or sign-off by an appropriately experienced or registered person.
- Maintain the documentation needed to support future technical and compliance reviews.
The incumbent will not initially carry sole professional responsibility for complex designs but must develop the knowledge and experience required to assume greater responsibility over time.
7. Technical support and fault-finding
- Provide technical assistance to production and service teams.
