CAD Design Engineer, Mechanical & Code-First Reverse Engineering

SoftAge Information Technology Limited; Hyderabad; On-site; INR 900,000 - 1,500,000; Full time

Job summary

SoftAge Information Technology Limited in Hyderabad, India, is seeking an experienced CAD Design Engineer, Mechanical & Code-First Reverse Engineering to join our design team. You will create and refine 3D models, parts and assemblies, and produce production-ready drawings.

You will reverse-engineer STL/mesh data into parametric, code-first CAD (build123d, CadQuery), assess AI-generated designs, and develop robust design workflows.

Qualifications

• 4+ years of hands-on CAD/mechanical design across multiple platforms.
• Proficient in parametric modelling, assemblies, engineering drawings, GD&T, and DFM.
• Experience with code-first CAD (build123d / CadQuery) or demonstrated scripting ability.
• Experience with reverse engineering and handling STL/mesh data.

Responsibilities

• Create and review data grounded in real CAD and mechanical design practice, parts, assemblies, drawings, and their reasoning.
• Reverse-engineer geometry from STL/mesh and infer sketches, features, datums, and key dimensional relationships.
• Evaluate AI-generated designs, 3D models, feature trees, and identify quality gaps and edge cases.
• Decompose complex modelling tasks into structured, step-by-step workflows for model learning and measurement.
• Build and assess parametric models, assemblies, and detailed 2D drawings across machined, sheet-metal, cast/moulded, and weldment parts.
• Judge design intent, constraints, and robustness of modelling approach.
• Apply and check GD&T, tolerancing, and DFM across the product design lifecycle.
• Validate code-first reconstructions against source geometry via deviation checks.

Job description

Job Title: CAD Design Engineer, Mechanical & Code-First Reverse Engineering

Type: Full-Time

Experience: 4+ years

About the Role

We are seeking an experienced CAD professional with strong expertise in 3D modelling, part and assembly design, and technical drafting. In this role, you will create and refine high-quality CAD models and engineering drawings, develop robust design workflows, and collaborate with engineering teams to deliver accurate, manufacturable, and production-ready designs.

What You'll Do

• Create and review data grounded in real CAD and mechanical design practice, parts, assemblies, drawings, and the reasoning behind them.
• Reverse-engineer geometry: take an STL/mesh with no feature history and reconstruct the design intent as parametric, code-first CAD (build123d), inferring sketches, features, datums, patterns, and key dimensional relationships.
• Evaluate AI-generated design solutions, 3D models, feature trees, mating strategies, drawings, and pin down failure cases, edge cases, and quality gaps.
• Decompose complex modelling and verification tasks into structured, step-by-step workflows the model can learn from and be measured against.

Domain Responsibilities

• Build and assess parametric models, assemblies, and detailed 2D drawings across machined, sheet-metal, cast/moulded, and weldment parts.
• Judge design intent, constraints, and robustness, modelling approach.
• Apply and check GD&T, tolerancing, and design-for-manufacturing across the full product design lifecycle (concept detailing design review handoff).
• Validate code-first reconstructions against source geometry via deviation and dimensional-accuracy checks.

Requirements

Must Have

• B.E./B.Tech/M.Tech/Ph.D in Mechanical Engineering (or closely related) from a Tier 1/Tier 2 institute (IIT, NIT, BITS, IIIT, DTU/NSUT, or equivalent).
• 4+ years of hands-on CAD/mechanical design with breadth across multiple platforms (Autodesk Fusion, SolidWorks, Creo, NX, CATIA, or Inventor), multiple part types, and the full design workflow.
• Strong command of parametric modelling, assembly design, engineering drawings, GD&T, and DFM.
• Working Python ability and genuine comfort with code-first CAD (build123d / CadQuery), or a clear track record of picking up scripting fast.

Good to Have

• Mesh processing (trimesh, Open3D, numpy-stl) and familiarity with OpenCascade/OCCT.
• Exposure to adjacent disciplines, surfacing, simulation-driven design, generative/topology optimization, or CAM handoff.
• PLM/PDM and configuration management.

Interested candidates are required to complete the attached CAD assessment as part of the application process.
