Agitator & Mixing Vessel Mechanical Design Engineer
AGITATOR & MIXING VESSEL MECHANICAL DESIGN ENGINEER
Location:
Doha, Qatar
Employment type:
Full-time
Workplace:
On-site
Indicative salary: QAR 13, per month
Candidates should have practical experience with agitator design, mixing vessels, shafts, impellers, mechanical seals, bearings or rotating process equipment. This is not a general sales or business development position. We are specifically looking for candidates capable of discussing mechanical design, torque, power transmission, shaft loading, impeller geometry and the mechanical configuration of industrial mixing systems.
Palomba General Trading LLC is looking for an Agitator & Mixing Vessel Mechanical Design Engineer to support technically demanding industrial process-equipment projects across Qatar and GCC markets. The role will focus on the mechanical design and technical evaluation of agitators, mixing vessels and associated rotating equipment used in food, pharmaceutical, nutraceutical, chemical, cosmetic and specialty ingredient processing. The successful candidate will work with customers, process engineers and international equipment manufacturers to define mechanical requirements and support the technical selection of suitable agitation and mixing configurations.
The position requires strong understanding of rotating equipment, mechanical loads, mixing geometry and industrial vessel design.
- Analyse customer requirements for industrial mixing and agitation systems.
- Support technical selection of agitator type according to product and process requirements.
- Evaluate impeller geometry, diameter and position.
- Review shaft length, diameter and mechanical loading.
- Evaluate torque and power requirements.
- Support selection of motors and gearboxes.
- Review critical speed and potential vibration issues.
- Evaluate shaft deflection and mechanical stability.
- Support analysis of radial and axial loads.
- Review bearing requirements.
- Support selection and evaluation of mechanical seals.
- Analyse vessel geometry and its impact on mixer configuration.
- Review tank diameter, liquid height and working volume.
- Evaluate requirements for baffles and internal vessel components.
- Support definition of top-entry, bottom-entry or side-entry mixer configurations.
- Evaluate mixing requirements for high-viscosity and low-viscosity products.
- Support technical assessment of anchor, turbine, propeller and high-shear mixing configurations.
- Coordinate technical discussions with international equipment manufacturers.
- Review mechanical drawings and equipment layouts.
- Support technical evaluation during design reviews.
- Assist with troubleshooting involving vibration, seal failure, shaft movement or insufficient mechanical performance.
- Support FAT and commissioning reviews when relevant.

We are looking for a genuinely technical mechanical engineer with practical understanding of industrial mixing equipment and rotating systems. The ideal candidate should be able to analyse a mixing application and understand how product properties, vessel geometry, agitator configuration, torque and mechanical loads affect equipment performance. The candidate should be comfortable reading technical drawings, reviewing mechanical configurations and discussing equipment design directly with OEM engineering teams.
Candidates whose professional background is primarily general sales, administration or non-technical business development are unlikely to…
