CAD Automation Engineer

Location: Greater London

# CAD Automation Engineer Engineering Hybrid Full -time## About the role### About Drafty AIDrafty AI turns 3D CAD models into production-ready 2D manufacturing drawings. We are SOLIDWORKS-native and process everything in-tool, so a customer's geometry never leaves their machine. Our engine pairs a deterministic rules layer with machine learning to produce release-ready drawings, flat patterns, bills of materials and exports, and to flag only the drawings that genuinely need a person.

We are early, backed by RudraX, and already running pilots with UK manufacturers. This is a chance to build the core of the product, not to maintain someone else's.### The role

You will own the layer where our software meets the CAD system. You will build and extend our SOLIDWORKS add-in, drive the CAD API integration, and turn a 3D model into a fully dimensioned, standards-compliant 2D drawing package, programmatically. You will work closely with our rules and ML engineers to decide what the automation does on its own and where a human is still needed.

This is a hands-on, high-ownership role. What you build is the product.## What you'll do### What you will do
• Build and maintain our SOLIDWORKS add-in and automation engine using the SOLIDWORKS API.
• Programmatically create drawing views, dimensions, annotations, title blocks, BOMs and balloons from 3D parts and assemblies.
• Automate sheet-metal outputs: flat patterns, bend tables, and DXF, DWG and PDF exports.
• Encode drawing standards and company conventions (ASME Y14 and ISO) as reliable, testable rules.
• Work with the ML team to combine deterministic logic with model-driven decisions, and to route exceptions cleanly.
• Extend support over time to further CAD systems such as AutoCAD and Inventor.
• Keep the code robust and well tested. It runs inside a customer's live CAD environment, so reliability is not optional.## What we're looking for### What we are looking for (essential)
* Hands-on experience building on the
* SOLIDWORKS API* (add-ins, or serious macro and automation work), or a comparable CAD API such as AutoCAD .NET / ObjectARX, Autodesk Inventor, Creo Toolkit or Solid Edge.
* Strong
* C# and .NET*, the primary stack for SOLIDWORKS add-ins.  or C++ experience is also welcome.
* A real understanding of
* manufacturing drawings*: drawing views, dimensioning, tolerances and GD&T, sheet metal, BOMs, and drawing standards.
* The ability to automate drawing creation end to end, from model to released output.
* Sound software engineering habits: version control, testing, and clean, maintainable code.## Nice to have### Nice to have
* More than one CAD API, for example SOLIDWORKS alongside AutoCAD or Inventor.
* Geometry processing, feature recognition or computational geometry.
* Exposure to Python and to working alongside ML engineers, since our engine is hybrid rules and ML.
* Experience shipping a commercial CAD add-in, or with the SOLIDWORKS partner and certification ecosystem.
* A background in mechanical, manufacturing or fabrication engineering, especially sheet metal and weldments.
* Comfort in an early-stage, zero-to-one environment.### What we offer
* A founding-level role on the core of the product, with real influence over how it is built.
* Genuinely hard and interesting problems where CAD, automation and AI meet.
* The backing of an operating company, with pilots already live.
* Competitive salary and equity, and flexible or remote working.###
