CAD Modeller/Designer/Detailer

Research & Development Digital Labs (Raddlabs), an innovation-focused technology company, is seeking an experienced CAD Modeller with a strong background in 2D and 3D design for civil and structural projects. This position is ideal for a technically skilled designer who can translate engineering concepts into accurate 3D models, connection details, and manufacturing-ready drawings.

You’ll be working as part of a multidisciplinary team to develop a browser-based design automation platform that integrates real-time 3D visualisation, engineering automation, and design documentation. The successful candidate will bring deep experience with AutoCAD, Revit, and related design tools, and will play a critical role in ensuring all modelled components meet engineering, visual, and manufacturing accuracy standards.

Open to Australian Applicants Only; International applicants will not be considered

Role Overview

The CAD Modeller is responsible for producing high-quality 2D and 3D design assets, component profiles, and technical drawings that accurately represent structural systems, junctions, and connections across a range of materials. Reporting to the Lead Software Architect, you’ll collaborate with software developers, engineers, and QA specialists to ensure that CAD models are accurate, consistent, and compatible with digital workflows.

You’ll be expected to work independently on drawing creation, contribute to engineering documentation standards, and support the modelling of complex assemblies for use in 3D visualisation and automation systems.

Key Responsibilities

3D Modelling and Detailing

• Create, update, and maintain accurate 3D models of structural and architectural components using AutoCAD, Revit, or similar design tools.
• Develop 3D profiles for different materials (e.g. steel, cladding, fixings), ensuring alignment with engineering and fabrication standards.
• Model detailed assemblies including junctions, bracing, and connections with precision suitable for downstream visualisation and analysis.

2D Drawing Production

• Produce 2D drawings, including elevations, sections, plans, and connection details for engineering documentation and manufacturing reference.
• Ensure drawings comply with applicable AS/NZS design standards, company templates, and project conventions.
• Annotate drawings with consistent dimensioning, labelling, and notes for clear technical communication.

Technical Collaboration

• Work closely with the software engineering team to provide CAD assets and ensure model fidelity in 3D visualisation workflows.
• Coordinate with structural engineers to interpret engineering inputs, ensuring correct geometry, sizing, and tolerances.
• Support design automation efforts by preparing parametric-ready geometry and exporting assets in suitable formats (FBX, DWG, DXF, etc.).

Documentation and Version Control

• Maintain organised model and drawing libraries in accordance with Raddlabs’ naming and versioning standards.
• Manage revisions and ensure traceability across multiple design iterations.
• Contribute to the creation of internal modelling standards and documentation for consistency and efficiency.

Quality and Compliance

• Review and verify drawings and models for technical accuracy, completeness, and compliance with structural design principles.
• Support QA testing of model outputs to ensure alignment between CAD data, Unity visualisation, and engineering calculations.
• Participate in peer reviews and apply feedback constructively to maintain high modelling standards.

Qualifications

• 5+ years of professional experience in 2D/3D CAD modelling, drafting, or design within the civil, structural, or construction sectors.
• Proficiency in AutoCAD, Revit, or equivalent BIM/design software.
• Strong understanding of structural detailing, material properties, and connection/junction modelling.
• Experience creating elevation, plan, and sectional drawings for fabrication or construction.
• Familiarity with engineering drawings and standards (AS/NZS) relevant to structural steel and building design.
• Experience preparing or exporting assets for use in 3D visualisation tools (Unity, Blender, or similar) is highly regarded.
• Bachelor’s degree, diploma, or certification in Civil Engineering, Structural Design, Drafting, or related discipline, or equivalent industry experience.

Key Competencies

• Exceptional attention to detail and accuracy in drafting and modelling.
• Strong spatial awareness and ability to interpret complex engineering inputs.
• Effective time management and the ability to meet tight deadlines with precision.
• Excellent written and verbal communication skills for technical collaboration.
• Self-motivated and capable of working independently in a remote environment.
• Familiarity with file management, version control, and collaborative design processes.
