Position Overview
TPS is seeking an experienced Senior Mechanical Design Engineer with deep knowledge in semiconductor facility design, including HVAC systems, cleanrooms, and process utilities. The successful candidate will lead mechanical design deliverables, perform engineering calculations, conduct CFD simulations, and prepare tender specifications for fast-track EPC/EPCM projects.
Key Responsibilities
Mechanical & Cleanroom Design
- Lead design of AHU/MAU systems, FFU layouts, chilled water systems, dry coils, CDA/N2 utilities, exhaust systems, and cleanroom airflow concepts.
- Conduct heat-load calculations, psychrometric evaluation, airflow balance, pressure cascade design, and equipment sizing.
CFD & Engineering Analysis
- Perform ANSYS CFD simulations for airflow, thermal behaviour, and particle control inside cleanrooms and controlled environments.
- Interpret simulation results and optimise designs to meet ISO cleanroom classifications and environmental stability requirements.
Detailed Engineering Documentation
- Prepare detailed design drawings, schematics, and mechanical layout plans using AutoCAD/Revit/BIM.
- Produce mechanical schedules, system diagrams, and material specifications.
Tender & Technical Submissions
- Prepare technical specifications, design narratives, and Basis-of-Design (BOD) documents.
- Support tender evaluations, respond to clarifications, and participate in design reviews.
Project Coordination
- Work closely with multidisciplinary teams and support authority submissions (BCA, SCDF, NEA, JTC).
- Provide design clarifications during construction, testing, and commissioning phases.
Requirements
- Degree in Mechanical Engineering or related discipline.
- 5-8 years of relevant design experience in semiconductor, cleanroom, or high-tech manufacturing facilities.
- Strong proficiency in ANSYS CFD or equivalent simulation tools.
- Solid experience in mechanical calculations, HVAC sizing, cleanroom engineering, and relevant codes (FM Global, NFPA 318, SS553, Fire Code, ASHRAE).
- Strong technical writing capability for preparing specifications and engineering reports.
- Independent, detail-oriented, and able to lead design tasks with minimal supervision.
What We Offer
- 5-day work week with a strong emphasis on work-life balance.
- Opportunity to work on advanced semiconductor EPC/EPCM projects.
- Supportive engineering team with opportunities to grow technical expertise (CFD, cleanroom design, BIM).
- Competitive remuneration and structured career development
