Product ML Engineer: 3D Perception & CAD Features

Mach9 Robotics Inc.; San Francisco (CA); On-site; USD 120,000 - 190,000; Full time

Job summary

Mach9 Robotics Inc. seeks an ML Engineer to build perception models for our AI-enabled CAD system. You will extract 3D object and line features from LiDAR point clouds and imagery, and ship new CV/ML features end-to-end from data strategy to evaluation.

You will work closely with customers to tailor workflows, adapt models to new sensors and regions, and develop robust evaluation pipelines, while growing your expertise in vision foundations and production deployment.

Qualifications

• BS or MS in Computer Science, EE, Robotics, or a related field, or equivalent experience.
• Strong coding abilities (preferably Python + Pytorch), and comfortable working with a large codebase.
• Hands‑on experience training or fine‑tuning a vision model (segmentation, detection, or 3D) through work, internships, or projects.
• Working knowledge of geometry for 3D perception: coordinate systems, transforms, projecting between images and point clouds.
• Curiosity and speed: you pick up new frameworks and papers quickly and can explain what you learned to teammates.
• Clear communicator with engineers, product, and the surveyors who use what you build.
• Fluent with AI coding assistants.

Responsibilities

• Ship new extraction features end to end: scoping with product and customer-facing teams, data and labeling strategy, model selection or fine-tuning, evaluation, and integration into Digital Surveyor.
• Build on existing model families and open-source tooling first (vision foundation models, VLMs, point-cloud backbones, classical geometry), and know what's out there and what each is good for.
• Adapt our production models to new object classes, regions, and sensor types as customers bring them.
• Build evaluation pipelines that measure improvements and regression alike.
• Iterate on feature extraction pipelines according to customer feedback and metrics changes.
