About the Role

Hi-Best Trading & Contracting is seeking a Senior Mechanical Application Engineer to join its technical team in Riyadh, Saudi Arabia. This full-time position focuses on engineering calculations, equipment selection, technical submissions, and application support for commercial and industrial HVAC systems, specifically dehumidification, solar water-heating, and heat-pump systems. The role is office-based and requires a strong engineering background, excellent communication skills, and the ability to manage technical project requirements independently.

Role Overview

The Senior Mechanical Application Engineer will be responsible for analyzing project requirements, performing accurate calculations, selecting appropriate solutions, and preparing comprehensive technical documentation. This role involves direct communication with consultants, contractors, clients, and manufacturers. Candidates whose experience is primarily limited to maintenance, drafting, site supervision, or general equipment sales are not suitable for this position, which requires a strong technical and detail-oriented approach.

Key Responsibilities

Perform psychrometric analysis, moisture-load calculations, cooling and heating-load calculations, airflow calculations, and hydraulic calculations.
Select and size commercial and industrial dehumidifiers for various applications including swimming pools, warehouses, cold rooms, hotels, commercial buildings, and industrial facilities.
Select and size solar water-heating and heat-pump systems based on hot-water demand, operating temperatures, climate conditions, and project specifications.
Review project specifications, mechanical drawings, tender documents, equipment schedules, and Bills of Quantities (BOQs).
Prepare technical submittals, compliance statements, equipment schedules, selection reports, calculation sheets, and technical-commercial proposals.
Develop mechanical layouts, schematic drawings, equipment arrangements, and installation concepts.
Review AutoCAD, Revit MEP, BIM, and MEP coordination drawings.
Coordinate with consultants, MEP contractors, clients, suppliers, and international manufacturers.
Participate in technical meetings, respond to consultant comments, and clearly explain proposed engineering solutions.
Provide value-engineering alternatives and technical support to the sales and project teams.
Support installation, testing, commissioning, troubleshooting, and system performance evaluation.

Qualifications and Experience

5-10 years of experience in mechanical engineering, with a focus on application engineering.
Demonstrated experience with commercial and industrial dehumidification systems.
Experience in indoor swimming-pool humidity control.
Familiarity with ducted, ceiling-mounted, and industrial dehumidifiers.
Experience with solar water-heating and heat-pump systems.
Proven technical coordination skills with consultants and MEP contractors.
Experience in testing, commissioning, and troubleshooting of mechanical equipment.
Proficiency with T*SOL, Polysun, or other system-selection software is an advantage.

Work Environment

This is a full-time, office-based position located in Riyadh, Saudi Arabia. The role involves working as part of a technical team and requires independent management of project technical requirements.
