CAD Engineer / 3D Design Engineer (Remote)

Job Title: CAD Engineer / 3D Design Engineer

Job Location : Remote

Employment Type : Full Time

About the Client:

Our client is building a marketplace and AI platform for additive manufacturing. They help companies convert legacy, custom, and hard-to-source parts into 3D-printable parts, then match those parts with the right suppliers, materials, and manufacturing processes. They are looking for a strong CAD Engineer in India who can help create, modify,

reverse-engineer, and prepare parts for 3D printing.

Responsibilities:

- Create 3D CAD models from 2D drawings, sketches, reference images, measurements, or customer specifications.

- Modify existing CAD files to improve fit, strength, manufacturability, or printability.

- Prepare parts for 3D printing across processes such as FDM, SLS, SLA, MJF, and metal additive manufacturing.

- Convert and clean files between formats such as STEP, STL, IGES, 3MF, DXF, and DWG.

-Review part geometry for common 3D printing issues such as thin walls, overhangs, unsupported features, tolerances, warping risk, and assembly fit.

- Create simple technical drawings with dimensions, tolerances, materials, and notes when needed.

- Work with the Accio3D team to recommend design changes based on material, process, and supplier capabilities.

- Help build a repeatable workflow for converting legacy and replacement parts into manufacturable 3D-printed parts.

- Maintain organized files, revision history, and documentation for each part.

Required Skills:

- Strong experience with CAD tools such as SolidWorks, Fusion 360, Siemens NX, CATIA, Creo, or Autodesk Inventor.

- Ability to create clean, parametric, manufacturable models.

- Experience modifying mechanical parts, brackets, housings, fixtures, mounts, adapters, covers, jigs, or replacement components.

- Understanding of tolerances, assemblies, fits, wall thickness, fillets, threads, ribs, and fastening methods.

- Familiarity with 3D printing design rules and additive manufacturing constraints.

- Ability to work from incomplete or messy inputs and still produce practical CAD output.

- Strong attention to detail and ability to communicate design tradeoffs clearly.

- Comfortable working quickly in a startup environment.

Nice to Have:

- Experience designing parts specifically for SLS, MJF, FDM, SLA, or metal 3D printing.

- Experience with reverse engineering, 3D scanning, or scan-to-CAD workflows.

- Knowledge of automotive, aerospace, industrial, defense, or manufacturing parts.

- Experience with GD&T.

- Ability to estimate material/process suitability for a part.

- Experience preparing files for vendors, suppliers, or manufacturing partners.

Example Projects:

- Recreate an obsolete automotive bracket from a 2D drawing.

- Modify a plastic cover so it can be printed in nylon using SLS or MJF.

- Redesign a part to reduce support material and improve strength.

- Convert a customer’s STEP file into a clean printable STL/3MF.

- Create multiple versions of a part for different materials or print processes.

- Add mounting holes, ribs, fillets, tolerance changes, or assembly features to an existing model.
