CAD Design Engineer, Mechanical & Code-First Reverse Engineering

SoftAge Information Technology Limited; Hyderabad; On-site; INR 1,200,000 - 1,900,000; Full time

Job summary

SoftAge Information Technology Limited in Hyderabad, India seeks an experienced CAD Design Engineer specializing in mechanical design and code-first reverse engineering to deliver high-quality, production-ready CAD models and drawings.

You will build robust design workflows, review data-backed designs, and collaborate with engineering teams to ensure manufacturability while exploring STL/mesh-based reconstructions and parameterized solutions.

Qualifications

• 4+ years hands-on CAD/mechanical design across multiple platforms.
• Strong command of parametric modelling, assembly design, GD&T, and DFM.
• Working Python ability and comfort with code-first CAD (build123d / Cad Query) or proven scripting speed.

Responsibilities

• 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.

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 detailed2D 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/Tier2 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 / Cad Query), 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.
