Mechanical Project Engineer (Industrial Ventilation)

About Us

Mitra Engineering Services is a 30-year-old Singapore turnkey contractor for industrial air filtration — dust collectors, fume extractors, oil mist collectors, paint booths, explosion protection, and centralised vacuum systems. We are the authorised Singapore partner of Donaldson, one of the world's leading filtration brands.

We don't sell off-the-shelf but instead, design, fabricate, install and service for years afterward. Our customers are primarily in the aerospace, pharmaceuticals, semiconductors, F&B, oil & gas, and metalworking sectors.

What this role is

This is a hands-on Project Engineer role under our Senior Project Engineer. You will own projects end-to-end, from customer enquiry, through engineering design and fabrication coordination, to site installation and commissioning. Roughly 50% office work (AutoCAD, calculations, proposals) and 50% site work (factory walkthroughs, installation supervision, troubleshooting). If you're looking for a pure-CAD office role, this is not it.

What you will do

Design dust collection, ventilation, and fume extraction systems in AutoCAD (equipment layout, ducting, hood design, filter sizing)

Conduct customer site assessments by walking operating factories in PPE, taking measurements and identifying constraints

Size equipment using establish standards

Prepare technical proposals, BOMs, and quotations

Coordinate with our in-house workshop on fabrication and with subcontractors on installation

Supervise installation, commissioning, and air balancing on customer sites

Troubleshoot performance issues post-handover and recommend corrective actions

What we are looking for

Diploma or Degree in Mechanical Engineering or HVAC/ACMV, pure electrical, electronics, software, or industrial design backgrounds will not fit this role

3–10 years of mechanical, MEP, ACMV, HVAC, ductwork, ventilation, or industrial process equipment experience — ideally with site exposure to factories or process plants

Working AutoCAD proficiency. You will be asked to demonstrate this live at interview

Comfortable on industrial sites in PPE (semiconductor fabs, pharmaceutical plants, metal fabrication shops, food factories, refineries)

Hands-on, detail-oriented and able to manage multiple concurrent projects

What you are expected to accomplish

First 90 days

Complete product study across Mitra's full range and the relevant Singapore standards and industry codes

Shadow senior team members on at least 10 customer projects

Study key governmental and regulatory standards.

Build familiarity with our workshop, in-house fabrication capabilities, key suppliers and subcontractors

Independently own end-to-end projects across all major product lines

Build direct working relationships with suppliers, vendors and subcontractors

Develop a track record of accurate costing and on-time delivery

Year 2 and beyond

Strong Advantages

Prior work with dust collectors, fume extractors, paint booths, oil mist or industrial vacuum systems (Donaldson, Camfil, Nederman, Filtermist, Plymovent or similar)

Experience with explosion protection

HVAC commissioning, air balancing, or testing background

Cleanroom or pharmaceutical facility installation work

Reading P&IDs, isometric piping, and electrical schematics

What we offer

Basic salary $4,500 – $6,000 depending on experience, including transport and phone allowance

Real ownership of projects, not just drafting support

Stable, established company with a strong recurring customer base
