Principal Engineer - Mechanical (Infrastructure)

Description

• Prepare and maintain technical documentation, design reports, feasibility assessments, and project records required by clients and regulatory bodies.
• Follow internal QA/QC processes to ensure the accuracy, completeness, and quality of all technical deliverables.
• Develop feasibility studies (both technical and commercial) for cooling strategies at master plan level, including district cooling and decentralized cooling scenarios for large developments.
• Stay informed of evolving industry regulations, authority standards, and best practices to ensure all mechanical infrastructure designs adhere to the latest requirements.
• Lead the development of district cooling plant tender documents, including concept process design and performance specifications for Design & Build (D&B) packages.
• Mentor and guide junior and mid-level mechanical engineers, sharing technical expertise and supporting their professional growth.
• Provide expert advice and technical guidance on all aspects of chilled water networks, gas distribution systems, district cooling plants, and mechanical utility infrastructure.
• Support site teams with technical clarifications and respond to contractor queries during construction phases.
• Act as a key point of contact for clients and regulatory authorities throughout the design and approval process.
• Prepare technical comparisons between multiple gas options such as LPG, SNG, and other fuel types.
• Review contractor shop drawings, material submittals, and method statements to ensure compliance with design intent and project specifications.
• Attend and organize project progress meetings, coordination workshops, and interface discussions with contractors, consultants, and authorities.
• Conduct chilled water and gas network hydraulic modelling using software such as Bentley WaterGEMS, SISHYD/GasWorks, and preferably FLUDIT for chilled water network analysis.
• Validate modelling outputs and incorporate findings into engineering design packages and tender documents.
• Lead the design of gas farms and associated piping networks for small-, medium-, and large-scale developments.
• Carry out feasibility assessments for gas supply systems, evaluating project demands and coordinating with the dry utilities team to determine optimal solutions (e.g., gas systems vs. electric alternatives).
• Provide complete engineering solutions, technical analysis, specifications, and procurement support for large-scale infrastructure projects—specifically district cooling/chilled water networks, gas systems, and mechanical components of pump stations.
• Ensure mechanical designs align with relevant standards and guidelines, including ASHRAE, Saudi Building Code (SBC), Civil Defense, NFPA, IGEM, and other applicable international and Saudi authority standards.
• Identify and mitigate potential risks associated with gas and mechanical utility projects, and establish contingency plans as needed.
• Compiling authority approval documentation in accordance with local authority standards to obtain approvals
• Analyse system performance, pressure requirements, flow distribution, and network stability to ensure optimal functionality and efficiency.
• Provide strategic technical input for procurement packages, material selection, and mechanical equipment evaluations.
• Foster a collaborative environment across multidisciplinary teams to drive high-quality design outcomes.
• Maintain strong client relationships through consistent communication, timely updates, and proactive issue resolution.

Requirements

• Bachelor’s degree in Mechanical Engineering (Master’s degree preferred).
• Proficiency in hydraulic modelling and design software (WaterGEMS, SISHYD/GasWorks, FLUDIT or equivalent).
• Ability to lead multidisciplinary coordination and manage multiple complex projects simultaneously.
• Minimum 10 years of professional experience in mechanical infrastructure design.
• Proven track record coordinating with Saudi authorities and government agencies.
• In-depth technical expertise in district cooling, chilled water networks, gas infrastructure, pressure regulating systems, and mechanical utilities.
• Strong experience in Saudi Arabia on large-scale infrastructure, master planning, utilities, or land development projects.
• Demonstrate strong familiarity with the design of LPG farms, Primary Pressure Regulating Stations (PPRS), Secondary Pressure Regulating Stations (SPRS), and related gas infrastructure components.
• Strong communication, stakeholder engagement, and project management skills.
