CAD Engineer (Revit / AutoCAD 3D)
Location: Heathrow Airport (On-site)
Salary: Attractive
Join Trinity Fire & Security Systems – Part of the PTSG Group
We\’re looking for a confident and capable CAD professional to join our Heathrow-based team, working on complex fire alarm system designs for a high-profile and long-standing client. If you enjoy seeing your work through from the early design stages right through to installation and ongoing support, this could be the ideal opportunity.
About the role
This isn\’t just design in a vacuum – you\’ll be embedded on site with direct access to installation engineers, involved in real-time decisions, and part of a 20-person project team that thrives on collaboration and shared success. From producing detailed 2D and 3D models to supporting project delivery across a live airport environment, your work will have real impact and visibility.
You\’ll take full ownership of your designs, contributing from the earliest concept stages through to completion. Expect interesting challenges, a varied workload, and plenty of autonomy to shape the way each project is delivered.
What you\’ll be doing
- Producing high-quality CAD drawings (2D & 3D) using AutoCAD and Revit (Essential )
- Managing drawing production across the full lifecycle of each project
- Coordinating with engineers and site teams to ensure buildability and compliance
- Following BIM and client standards to produce consistent, well-structured outputs
- Acting as a key part of a friendly, experienced, site-based project team
What we\’re looking for
We\’re open to backgrounds – whether you\’ve worked on MEP systems, security installations, ductwork or anything similar, we\’re really looking for someone with solid technical drawing skills and the right mindset.
You\’ll need:
- Proficiency in AutoCAD (2D & 3D) and Revit
- Experience producing commercial design work, ideally in MEP or similar fields
- A hands-on approach and good problem-solving instincts
- Full right to work in the UK (we cannot offer visa sponsorship)
- The ability to pass an enhanced DBS check
Fire system experience is helpful but not essential – we can support the right person to learn on the job if you bring the core CAD skills and practical thinking.
What we offer
- Competitive salary (Attractive when compared with industry)
- 23 days holiday + bank holidays
- Company vehicle and paid travel
- Pension scheme & life assurance
- Employee assistance programme
- A supportive working environment with real team spirit
