The Opportunity

Cosaf Environments is looking for a practical, detail-focused CAD Engineer / HVAC Design Technician to support the delivery of industrial and commercial heating, ventilation, cooling and environmental control projects.

This is a hands-on technical position, with opportunities to work across a variety of challenging systems and site environments. We are looking for somebody who can take ownership of their drawings, identify buildability issues early and contribute ideas that improve the quality of our installations.

Develop practical layouts for ductwork, ventilation equipment, air handling plant, cooling and heating equipment, pipework and associated services.
Coordinate equipment locations, routing, access clearances and interfaces with architectural, structural and other M&E services; identify clashes and propose workable solutions.
Attend project sites alongside engineers and project managers and progressively undertake measured surveys and verification of existing services and dimensions.
Translate approved design information, specifications, supplier details and site observations into clear, buildable drawing packages.
Maintain accurate drawing registers, revision histories, file structures and issue records from design development through installation and as-built handover.
Liaise with the design, estimating, procurement and contracts teams, as well as manufacturers and specialist suppliers, to resolve drawing queries and support project delivery.
Support technical submittals, equipment schedules and project documentation, and help develop consistent CAD standards, templates and efficient 3D workflows.
