Mastery Co is seeking an experienced Carpenter for a fixed-term contract role based in Revesby, Sydney, working on an $800,000+ residential extension and renovation. The contract runs for approximately six months, or until project completion. The project is currently in the demolition phase, so an immediate start is ideal. As a Design + Construct firm, Mastery Co produces all the plans, documentation, and 3D models for projects in-house — giving clear, well-organised drawings and cutting lists to work from on site, with the Director Mitch on hand throughout both the design and construction process.

Key responsibilities

- Work on the tools across all stages of a high-quality residential extension and renovation, from demolition through to completion
- Execute carpentry work from detailed 3D models and documentation
- Work closely with Mitch, who is available across both the design and construct side of the project for support and direction
- Maintain a high standard of workmanship on a project where quality and attention to detail matter
- Build to Passivhaus principles, including airtightness detailing with Pro Clima products
- Keep site records up to date in Wunderbuild

- Always looking for the next upskilling opportunity and keen to keep sharpening your craft
- Reliable, take pride in your work, and comfortable working independently on site
- Must have your own vehicle and own tools
- Sydney-based, able to reliably attend site in Revesby
- Knowledge of Passivhaus principles highly regarded, particularly airtightness and taping systems such as Pro Clima
- Experience with the Wunderbuild system preferred
