About LimitlessCNC

Limitless CNC 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

Our algorithm team develops the core intelligence: 3D perception, machining strategy optimization, physics‑aware models and more.

We’re looking for a Senior Algorithm Developer with a strong algorithmic background in both classical and deep learning methods.

What You’ll Do

• Develop, release and improve algorithms and models for recommending the best machining operations that balance customer‑valued KPIs such as machining time, machining tolerances and tool wear.
• Dive deep into the CNC machining domain to cultivate intuition to inform your algorithm development decisions.
• Collaborate with the Product team to discover and drive improvements in our human‑AI interface.
• Own your models in production. Validate your solutions against real‑world machining scenarios and customer parts.
• Research novel approaches to continuously improve our core technology.

Requirements

• +5 Years of experience in classic algorithm development / deep learning / ML model training and evaluation.
• Experience in releasing and monitoring your algorithms and models in production environments.
• Ability to reason about 3D geometry, machining tolerances, and manufacturing constraints.
• B.Sc. or M.Sc. in Mechanical Engineering, Computer Science, Physics or a related field.
• US citizenship or Green Card (required for ITAR‑regulated work and team location).

Bonus

• Experience with open source 3D geometry libraries such as OpenCASCADE, Trimesh, Pytorch3D and OpenVDB.
• Experience with computational geometry, graph algorithms, scheduling optimization, or constraint satisfaction.
• Strong understanding of CNC machining processes – milling, turning, or both.
• Experience in toolpath generation or CAD/CAM internals.

Why Join LimitlessCNC

• Opportunity to lead a product at the forefront of the Physical AI revolution.
• Competitive salary and meaningful equity.
• Health, dental, and vision insurance.
• 401(k) plan.
• Flexible PTO.
• Home office stipend and equipment.
• Parental leave.
