Job description

Sungai Design is a design firm transforming recycled materials into furniture and lifestyle products. Based in Bali, we bring together design, recycling, and craftsmanship to give discarded materials a new purpose. From chairs, to yoga mats, to ceramics, to music speakers - we are showing that waste is not the end of the story.

About the role

You’ll help take furniture, products, and bespoke projects through the full development process: design → costing → prototype → production → catalogue → mass production.

This means developing concepts, preparing accurate drawings and costed bills of materials, working through prototype revisions, and completing the documentation needed to manufacture and present the finished product.

You’ll take responsibility for your assigned work at each stage, with technical input and approvals from the project and production leads.

What you’ll do

Design and 3D development

Translate client briefs, sketches, and references into accurate 3D models.

Develop new products and adapt existing designs for different dimensions, materials, and project requirements.

Explore design options with attention to functionality, visual, material use, and ease of manufacture.

Prepare renderings and visualizations for internal reviews and client presentations.

Technical drawings and documentation

Produce detailed manufacturing drawings, including dimensions, tolerances, sections, construction details, and assembly information.

Prepare cutting plans, material specifications, and assembly or installation guides as required.

Keep models, drawings, and project files organized, clearly named, and up to date.

Ensure the final documentation reflects the approved product and any changes made during production.

Materials and costing

Prepare a complete bill of materials (BOM) for each design, including materials, components, hardware, quantities, and specifications.

Work with the production team to cost the BOM and estimate labour, fabrication, finishing, material waste, and other relevant sample costs before a prototype is built.

Clearly identify assumptions and missing cost information for review.

Revise designs against agreed cost targets and update estimates as designs change.

Prototyping and production

Work directly with the engineering and production team to explain designs and resolve practical manufacturing questions.

Follow prototypes through fabrication, review the results, and document necessary revisions.

Adjust designs in response to material behaviour, production constraints, quality requirements, and cost.

Track outstanding design issues, communicate blockers early, and follow revisions through to completion.

We are looking for someone hands on who is able to build and use tools themselves.

Product completion and catalogue preparation

Prepare the final product information needed for catalogue and sales use, including approved dimensions, materials, finishes, specifications, and visuals.

Ensure drawings, BOMs, and assembly information are complete and consistent before final handover.

Support both catalogue products and custom projects from initial development through production.

What we’re looking for

A diploma or degree in Product Design, Industrial Design, Interior Design, Architecture, Mechanical Engineering, or a related field—or equivalent practical experience.

Around 1–3 years of relevant professional experience in physical product development, furniture design, or a related manufacturing environment.

Good English proficiency would be an added advantage.

Experience working within a product development team, collaborating directly with production or fabrication teams.

Evidence of having helped take at least one physical product from design through prototyping and production, including final documentation or catalogue handover.

Proficiency in a 3D modelling tool such as Rhinoceros 3D, SolidWorks, SketchUp, or equivalent.

Ability to produce clear technical drawings and complete BOMs, with practical experience contributing to product or sample costing.

A working understanding of materials, construction methods, and manufacturing processes.

Strong attention to detail, clear communication, and reliable follow-through.

Curiosity, willingness to learn, and an interest in working with recycled materials.

Useful additional experience

Furniture, bespoke products, or recycled-plastic product development.

CNC machining, woodworking, metal fabrication, or plastic manufacturing.

Rendering using KeyShot, Blender, or equivalent.

Spreadsheet tools for BOMs and costing.
