Full-time position

This is an opportunity to work on the geometry and data infrastructure behind next-generation CAD foundation models, building systems that enable AI to understand, reason about, and ultimately engineer physical systems.

THE ROLE

As a CAD / Geometry Engineer, you’ll build the geometry and data pipelines that power advanced AI models for structured 3D parametric CAD. You’ll work closely with an AI research team and contribute to decisions around data representation, geometry processing, reconstruction, verification, and model architecture.

WHAT YOU’LL DO

Build high-performance geometry pipelines for machine learning applications
Ingest and process CAD data across multiple file formats
Extract and convert B-rep geometry, feature trees, and parametric data into universal representations for ML
Work directly inside CAD kernels to extract, manipulate, and reason about solid geometry programmatically
Develop automated systems for geometry extraction, encoding, reconstruction, and verification
Collaborate closely with AI researchers as geometry representations evolve alongside the models
Contribute to architecture and engineering design decisions involving geometry and data representation
Depending on experience, take ownership of CAD data collection and curation

REQUIRED EDUCATION

PhD in Computational Geometry, Physics, Mathematics, Computer Science, or a related field

REQUIRED EXPERIENCE

Experience

6+ years of experience in computational geometry or CAD kernel engineering
Strong hands-on experience working with B-reps and parametric geometry
Experience in design and manufacturing, aerospace, robotics, or a closely related domain
Startup experience is preferred

Technical Skills

Strong C++ or Python programming skills for geometry processing
Practical experience with CAD or geometry kernels
Strong understanding of computational geometry and solid modeling fundamentals

NICE TO HAVE

Hands-on experience with Parasolid, ACIS, or OpenCASCADE
Experience with NURBS and solid modeling
Direct Parasolid experience
Experience with high-performance data pipelines
Experience contributing to AI/ML systems involving structured geometry

THIS ROLE IS NOT FOR

This position is not primarily a CAD software-user role. Candidates whose experience is limited to being a SolidWorks/Fusion power user or holding CAD software certifications, without experience in geometry algorithms, CAD kernels, computational geometry, or geometry pipelines, may not be a fit.

WHY THIS OPPORTUNITY IS UNIQUE

You’ll be working on core geometry infrastructure for foundation-model-scale AI. The team has already developed a generative model for structured 3D parametric CAD and is continuing development toward increasingly capable AI systems for engineering design. You’ll have the opportunity to:

Own critical parts of the model’s geometry backbone
Work directly with B-reps, parametric data, and feature trees
Collaborate closely with AI researchers
Influence how geometry is represented and consumed by foundation models
Work on problems spanning CAD, computational geometry, manufacturing, and AI

TEAM

You’ll join a small, highly technical team with a flat structure, working closely with experienced researchers, engineers, and founders. The team includes backgrounds spanning Meta, Autodesk Research, Stanford, MIT, Samsung Research, and CMU.

WHO SHOULD APPLY?

If you’ve worked on geometry algorithms, CAD kernel internals, or large-scale geometry processing systems and want to apply that expertise to AI-driven engineering, we’d love to hear from you. Interested? Apply now or DM me with your resume/profile.

Visa sponsorship record

No public sponsorship records found

We didn't find H-1B, H-1B1, E-3 or green card (PERM) filings under the name carnaby fox in the Department of Labor and USCIS data. That doesn't mean the job can't be sponsored — the company may file under a different legal name, be new to sponsorship, or sponsor a visa that isn't in these datasets (for example H-2B or J-1).

Tip: ask the recruiter early, in writing, which visa they sponsor and whether they cover the legal and filing fees.

Which visas can work for this job

Occupation: Engineers, All Other (SOC 17-2199) — estimated from the job title.

Mentioned in the listing
H-1B, OPT
H-1B cap-exempt employer
Regular cap-subject employer — a new H-1B needs to win the lottery in March (unless you already hold cap-counted H-1B status).
TN (citizens of Canada and Mexico)
This kind of role may fit the USMCA profession “Engineer” — it depends on the actual duties. No lottery, no cap; you need the matching degree or license.
E-3 (Australia) and H-1B1 (Chile, Singapore)
Same degree requirement as H-1B, but no lottery and a separate quota that is rarely filled.
O-1 (extraordinary ability)
For candidates with awards, publications, press, a high salary or critical roles at distinguished organizations. No cap, no lottery; the employer files a petition.
STEM OPT extension (F-1 students)
Requires an E-Verify employer. We didn't find this company in the E-Verify list — ask HR.

Salary vs prevailing wage

Level IV (fully competent)

Engineers, All Other · San Francisco-Oakland-Fremont, CA. Annual prevailing wages set by the Department of Labor (OFLC).

L1L2L3L4

Level	Prevailing wage	H-1B lottery odds*
Level I	$98,051	~15%
Level II	$130,146	~31%
Level III	$162,261	~46%
Level IV	$194,355	~61%

This job pays $220,000–$300,000 a year — that's Level IV (fully competent). In the wage-weighted H-1B lottery a Level IV registration gets 4 entries; estimated selection chance about 61% — better than average.

* Odds are DHS projections for the FY2027 wage-weighted lottery (actual results vary by year and employer). Since the FY2027 cap season the H-1B lottery is weighted by wage level: Level I = 1 entry, II = 2, III = 3, IV = 4. The level is set by the offered wage against the prevailing wage for the occupation and worksite. Separately, a $100,000 fee for new H-1B petitions for workers outside the US was announced in 2025; as of September 2026 a federal court ruling keeps it unenforceable while appeals continue — check the current status.
