Job description

LimitlessCNC is building the AI co‑pilot for CNC programming, helping manufacturers automate and accelerate machining processes directly inside their existing CAM environments.

We are a rapidly expanding, top‑VC‑backed startup with an exceptionally talented core team. In under 18 months, we have raised +$25M and are actively collaborating with major global manufacturers in the Aerospace & Defense, Automotive, and Industrial Machinery sectors.

You’ll join a hands‑on, execution‑driven team where ownership is real, pace is fast, and impact is immediate.

About the Role

We're looking for a CAM Software Engineer to build the native bridges that connect our AI engine to the CAD/CAM systems our customers run every day. You'll work primarily in C# and C++, developing plugins, add‑ins, and COM‑based integrations against industrial 3D modeling and CAM software - handling geometry extraction, feature data, and the real‑time data flows between desktop applications and our cloud platform. This is a hands‑on engineering role at the seam between heavy desktop CAD/CAM software and a modern AI backend, where deep familiarity with 3D software internals and native interop directly shapes the product.

What You’ll Do

• Build and own native integrations with industrial CAD/CAM software - plugins, add‑ins, and COM‑based bridges in C# and C++ that connect our AI engine to systems like SolidWorks, Siemens NX, Mastercam, and Catia
• Extract and process geometry, features, and model data from 3D CAD/CAM environments through their native APIs, SDKs, and COM interfaces
• Help translate our generic, CAM‑agnostic Actions into vendor‑specific operations - implementing the mapping logic either in the Python AI engine or directly in the plugins themselves
• Own the WebSocket‑based protocol bridging desktop CAD/CAM plugins to the platform, including STEP file handling and feature recognition data flows
• Package, deploy, and maintain integrations across multiple CAD/CAM vendors and versions, managing compatibility, installers, and the realities of third‑party desktop environments
• Work closely with the backend and AI teams on API contracts, the prediction/preprocessing pipeline, and the data flow between desktop and cloud
• Set integration standards: reliability, error handling across native boundaries, debugging interop issues, performance, and testing practices
• Serve as the in‑house expert on CAD/CAM integration, partnering with customers and application engineers to understand how real machinists use these tools day to day

Requirements

• 4+ years of software engineering experience, with strong, hands‑on C# and/or C++ development
• Experience working with 3D‑based software - CAD, CAM, modeling, simulation, or similar - whether as an integrator, plugin developer, or power user
• Hands‑on experience with COM programming and native interop (COM/ActiveX automation, P/Invoke, C++/CLI, or equivalent)
• Experience building plugins, add‑ins, or integrations against third‑party desktop applications via their native APIs or SDKs
• Comfort with real‑time / event‑driven communication (WebSocket or similar) between desktop clients and a cloud backend
• Strong debugging skills across native and managed code boundaries, and comfort working in Windows desktop environments
• Ability to work in a polyglot environment - your work is primarily C#/C++ but you'll interface with our Elixir/Phoenix and Python services

Bonus

• Direct experience developing against one or more major CAD/CAM packages: SolidWorks, Solid Edge, Siemens NX, Mastercam, hyperMILL, TopSolid, Catia, or 3DEXPERIENCE (3DX)
• Familiarity with geometry kernels and CAD interop formats (STEP, IGES, Parasolid, ACIS, OCCT)
• Domain knowledge of CNC machining, CAM workflows, toolpaths, or manufacturing processes
• Experience with Windows installers, code signing, and deploying software into enterprise/regulated customer environments
• Background in geometry processing, computational geometry, or 3D mesh / B‑rep manipulation
• Comfort working in a Python codebase (our AI engine) and/or exposure to Rust for tooling or performance‑critical components

Why Join LimitlessCNC

• Opportunity to lead a product in the for‑front of the Physical AI revolution.
• Work on cutting‑edge technology for real‑world manufacturing.
• Small, high‑caliber team where your work has immediate impact.
• Flexible hybrid/remote environment and ownership over your function.
