Marathon is seeking an experienced and design-focused Architect to join our growing architectural team in Sydney.
This is an opportunity to work within an integrated design and construction business where architectural ideas move beyond the drawing board and become high-quality, buildable outcomes.

As part of Marathon's in-house team, you will collaborate closely with clients, consultants, project managers, manufacturing specialists and construction teams. You will play an important role in maintaining design quality while incorporating buildability, efficiency and the practical requirements of modular construction.
