ML Engineer: 3D Perception for AI CAD

Mach9 Robotics Inc.; San Francisco (CA); On-site; USD 120,000 - 180,000; Full time

Job summary

Mach9 Robotics Inc. is seeking an early-career ML Engineer to build perception models for our AI-enabled CAD system. You will extract 3D object and line features from LiDAR and imagery, train models, and ship new features end-to-end from data strategy to evaluation.

You will work closely with customers to develop CV/ML pipelines, adapt models to new sensor types, and contribute to production deployments for field surveyors and engineers.

Qualifications

• BS or MS in Computer Science, Electrical Engineering, Robotics, or a related field.
• Strong coding abilities (Python + PyTorch) and comfortable with a large codebase.
• Hands-on experience training or fine-tuning a vision model (segmentation, detection, or 3D).
• Working knowledge of geometry for 3D perception: coordinates, transforms, projecting between images and point clouds.
• Curiosity and speed: rapidly learning new frameworks and papers and explaining learnings.
• Clear communicator with engineers, product, and 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.
• Adapt 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.
