JOB SUMMARY

The Mechanical DesignEngineer supports the delivery of high‑quality mechanical engineering designsfor water, wastewater, and environmental projects under the guidance of theMechanical Design Lead and Mechanical Discipline Manager.

Therole focuses on contributing to mechanical design activities, performingequipment sizing calculations, preparing specifications and engineeringdocuments, supporting procurement and post‑PO activities, and coordinating withmultidisciplinary teams. The Mechanical Design Engineer is expected toprogressively contribute technically to project design, ensure compliance withapplicable standards, and deliver reliable engineering outputs within agreedschedules, cost and quality requirements.

Mechanical Design & Calculations

• Prepare mechanical design deliverables for proposal and execution phases under supervision.
• Perform basic to intermediate mechanical sizing calculations, including but not limited to:
  Pump total dynamic head (TDH / TMH)
  Blower pressure and airflow requirements
  Service air consumption
  Room ventilation and heat dissipation requirements
• Assist in preparing mechanical layouts, equipment arrangement drawings, and interface sketches.
• Review P&IDs for mechanical scope and report inconsistencies, clashes, or improvement opportunities to senior engineers.

Equipment Specification & Design Support

• Assist in preparing and maintaining mechanical equipment lists throughout the project lifecycle.
• Support development of equipment specifications and data sheets based on:
  Client and project requirements
  Process design inputs
  Site, installation, and maintenance constraints
• Incorporate operability and maintainability considerations into mechanical design documents.
• Support in preparation of Purchase Order (PO) / Requisition (PR) from approved Technical Specification (TS).

Supplier Technical Review / Post-PO Engineering

• Assist in reviewing supplier technical offers for compliance with inquiry specifications.
• Support preparation of Technical Comparison Tables (TCT) and technical clarification questions.
• Participate in technical discussions with suppliers together with senior engineers, project teams, or buyers.
• Perform post‑Purchase Order (PO) mechanical engineering activities, including review and checking of vendor drawings, datasheets, calculations, and specifications for compliance with contract requirements and approved design basis.
• Prepare review comments and support vendor document approval under supervision of the Mechanical Design Lead

Cost & Proposal Support

• Provide mechanical inputs for quantity take‑off and cost estimation activities.
• Support proposal teams by preparing technical clarifications, equipment datasheets, and design assumptions.
• Identify basic opportunities for design or cost optimization and raise them to senior engineers for review and validation.

Multidisciplinary Coordination

• Coordinate with civil, electrical, instrumentation, automation, and process engineers to ensure design consistency.
• Identify interface issues early and escalate to the Mechanical Design Lead when required.
• Participate in design review meetings and project coordination meetings as assigned.

Standards & Design Compliance

• Apply applicable Philippine codes and regulations relevant to mechanical systems.
• Apply relevant international standards (ISO, API, ASME, IEC, as applicable to project scope).
• Ensure mechanical deliverables follow company engineering guidelines, templates, and standard practices.
• Implement review comments accurately and within agreed timelines.

HSE Responsibilities (Design Phase)

• Integrate basic HSE principles into mechanical designs and equipment layouts.
• Participate in Design Risk Assessments (DRA), focusing on mechanical hazards such as:
  Rotating equipment
  Pressure systems
  Noise, vibration, and heat exposure
• Comply with applicable HSE requirements during FAT, SAT, and site activities.
• Apply constructability, operability, and maintainability principles under guidance from senior engineers.

Quality & FAT / SAT Responsibilities

• Prepare mechanical engineering documents in compliance with company quality systems (OMEGA or equivalent).
• Ensure accuracy, completeness, consistency, and proper revision control of design deliverables.
• Address quality review comments promptly and correctly.
• Support the preparation and/or review of Factory Acceptance Test (FAT) and Site Acceptance Test (SAT) procedures for mechanical equipment.
• Attend FAT and SAT activities when assigned, together with senior engineers or project representatives.
• Review FAT/SAT results and assist in preparing punch lists, observations, and follow‑up actions.

Site Support, Pre‑Commissioning & Commissioning

• Provide mechanical engineering support during site installation, pre‑commissioning, and commissioning phases when required.
• Support troubleshooting of mechanical equipment issues in coordination with site teams, vendors, and senior engineers.
