The candidate will be responsible for ensuring that grease batches are manufactured safely, consistently, efficiently, and according to applicable specifications and customer requirements.

This is a hands-on leadership role requiring the ability to independently supervise grease production from raw-material charging through reaction, processing, homogenization, cooling, milling, testing, final approval, and packing, while ensuring that products meet export-grade and government/defence procurement specifications.

Key Responsibilities

1.



Grease Production & Batch Operations

- Plan, execute, and supervise grease manufacturing batches across open kettle processes, ensuring adherence to standard formulations and process parameters (temperature ramps, reaction time, cooling rates, milling/homogenization).
- Lead production of the full grease portfolio, including:
- Lithium Grease (AP3, MP3, Long Life Servo/HP type)
- Lithium Complex Grease (Licom 2, Licom 3, Licom Blue)
- Calcium Anhydrous Grease (Calcium MP3, EP0/00/000/2/3, Calcium Gel)
- Calcium Sulphonate / Calcium Complex Grease
- Sodium Grease (Wheel Bearing Grease)
- Clay-based Grease
- Chassis / Crushing Grease
- Specialty defence/institutional greases
- Oversee blending and processing of associated oils: engine oil, gear oil, cutting oil, hydraulic oil, and rust preventive oil.
- Manage batch transfer, circulation, and pilot kettle trials for recent formulations or customer-specific/export specifications.
- Ensure smooth operation of homogenizers, milling machines, boilers, cooling towers, cooling kettles, motors, and small-pack filling lines.
- Coordinate safe tanker unloading operations as per process and safety protocol.

2. Quality & Testing

- Penetration, Drop Point (ASTM D566/D2265), Alkalinity, Acidity, Water Content,



Heat Stability, Copper Corrosion, Oxidation Stability, Oil Separation, Roll Stability, Four Ball Weld Load, Timken OK Load, Water Wash-Out, Wheel Bearing Test, SAP Value.
- Base oil viscosity extraction, Kinematic Viscosity (40C/100C), Flash Point, Pour Point, TAN/TBN, Aniline Point, Demulsibility, pH, Ash Content, Evaporation Loss.
- Ensure batch release aligns with internal specs and customer/export/government quality requirements.
- Investigate and resolve off-spec batches, working with the lab to identify root cause (formulation, process, or raw material related).

3. Compliance & Order Readiness

- Ensure production processes and documentation meet the standards required for export shipments and government/institutional tenders.
- Maintain batch manufacturing records, process logs, and traceability documentation suitable for export/government audit and inspection requirements.
- Support QA/regulatory teams in preparing technical data sheets, COAs, and compliance documentation for international and government buyers.

Required Qualifications

- Any Degree/diploma - Bachelor’s/ Master's from a recognized university.
- 3-5 years of hands-on experience in grease and lubricant manufacturing, with proven exposure to open kettle batch processes.
- Demonstrated working knowledge of Lithium, Lithium Complex, Sodium, Clay, and Calcium Sulphonate grease chemistries.
- Practical experience with grease plant machinery: homogenizers, milling machines, boilers, pressure/open/cooling kettles, cooling towers, batch transfer systems, and pilot plant kettles.
- Strong understanding of oil and grease testing parameters and their significance to product performance.
