Job description

Citra (citra.build) is a rapidly growing innovative company of talented architects, engineers, contractors and developers based in Ndabeni, Cape Town. Our vision is to create a living environment that provides a better everyday life for present and future generations from all walks of life. We thrive to use cutting edge design and technology to build beautiful premium and affordable homes of outstanding quality.

At Citra you will experience a dynamic and inspiring environment in an international creative team. Our value chain entails the entire cycle from raw land, urban design, design of residential and non-residential buildings, as well as the construction either through subcontractors or our own internal construction team.

Citra makes extensive use of new technologies. This applies to our own building technology and manufacturing that we continuously further develop and optimize and to all other areas such as the tools for architectural and structural design, and our general working with cloud documents.

Industry: Advanced Manufacturing / Construction / Digital Fabrication

Reports To: Technical Production Lead

The Role: Bridging Design and Machine

We are looking for a highly skilled Technical Draughtsperson to join our production modeling team. This isn't a standard architectural drafting role; you will be the link between complex Structural Engineering intent and precision CNC manufacturing.

You will be responsible for taking "Issued for Construction" (IFC) models and developing them into high-fidelity Shop Drawings and CNC-ready files for our hotwire cutting machines. If you love seeing your digital work turn into physical products in real-time, this is the role for you.

Key Responsibilities

• Production Modeling: Develop detailed 3D models and 2D shop drawings in Revit and Rhino, ensuring all structural and fabrication tolerances are met.
• BIM Coordination: Manage model data within a BIM environment (ACC - FORMA), ensuring version control and seamless handovers between Engineering and Production.
• CAD Translation: Utilize Rhino to prep complex geometries for CNC cutting, accounting for material kerf and heat-melt variables.
• Drawing Interpretation: Read and interpret structural, architectural, and MEP drawings to identify potential clashes before they hit the factory floor.
• Collaboration: Work directly with the Technical Production Lead, Factory Manager and CNC Operators to optimize cut paths and reduce material waste.

Requirements & Qualifications

• Technical Mastery: High proficiency in Revit (Families and Detailed Modeling) is non-negotiable.
• Versatility: Proven experience in Rhino (& Grasshopper)
• BIM Literate: A solid understanding of BIM workflows, Level of Development (LOD 400), and collaborative data environments.
• Industry Background: 3+ years of experience in a Production, Fabrication, or Construction environment. You must understand how things are built, not just how they look on screen.
• The "Maker" Mindset: Ability to troubleshoot geometric problems and a passion for precision.

Software Stack

Must Have:

Revit skills Knowledge of Autodesk FORMA (ACC)

Highly Desirable:

3D Rhino skills Knowledge of Grasshopper

Why Join Us?

We are a forward-thinking manufacturing unit at the cutting edge of digital fabrication in South Africa. We offer a high-trust environment where your technical input directly shapes the physical output of our factory.
