ML Engineer, Product
San Francisco, CA$180k - $300kFull-timePosted 2w ago
About the role
ML Engineer role at Mach9, a YC-backed AI CAD startup, focusing on perception models for 3D feature extraction from LiDAR and imagery to power an AI-enabled CAD system for civil engineering. Product-focused role with end-to-end feature shipping and close collaboration with customers.
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 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.
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.
