Job Description

Senior ML and Research Engineer to own the end-to-end lifecycle of an AI driven CAD product, with onsite work in San Mateo, CA.

Responsibilities

Develop and refine bespoke deep learning models tailored to CAD workflows, delivering high quality next-step recommendations
Create and maintain robust Python based training and evaluation pipelines, covering data preprocessing, experimentation, and both offline and online metrics
Design scalable model serving and backend components to ensure fast, reliable features that integrate with CAD environments
Collaborate with the founder and early customers (mechanical and hardware engineers) to map real-world workflows into ML formulations
Own ML features end-to-end from research and prototyping to productionization, deployment, and monitoring
Partner with the engineering team on core product and infrastructure tasks including backend, APIs, data models, and performance
Establish and enforce best practices for experimentation, logging, and model comparison
Stay current with relevant ML research (sequence models, geometric deep learning, representation learning) and apply pragmatically

Requirements

4+ years of hands-on ML experience, or an equivalent research-based Master’s or PhD
Proven track record of training and improving deep models, not solely relying on hosted APIs
Expert with PyTorch (preferred), TensorFlow, or JAX — capable of implementing and modifying custom architectures, loss functions, and training loops
Strong production-ready Python skills — clean, well-structured code with tests, documentation, and thoughtful abstractions
End-to-end ownership experience — from data to deployment, including training pipelines, hyperparameter tuning, and shipping models into real products
Ability to work closely with founders and translate open-ended product requirements into concrete ML formulations

About the Company

The company is building AI powered CAD to fundamentally change how hardware is designed and manufactured. Founded by repeat deep-tech entrepreneurs with experience from top YC companies and frontier robotics, the team is turning CAD into an intelligent collaborator that understands design intent and autocompletes the work, enabling hardware teams to shift from weeks of repetitive clicking to minutes of high-leverage engineering. YC-backed, a 5–10 person team based in San Mateo.

About the Role

This is the first senior ML and research hire at the company. You will own the full lifecycle of ML systems powering the AI driven CAD product, moving between deep research and hands-on engineering, scoping problems with the founders, designing and training novel models, and shipping them into robust production code. Over time you will have the opportunity to define the roadmap for CAD focused ML research, mentor future hires, and grow into a Staff or Principal IC or early engineering leader.

Nice to Have

Experience with geometry, graphics, CAD, 3D representations, or robotics
Familiarity with cloud ML platforms (AWS/GCP) and backend frameworks (FastAPI, Flask, Django)
Published research or meaningful open-source contributions demonstrating novel technical work

Interview Process

Short online survey (about 15 minutes)
Initial call (30–45 minutes) with the founders
Take-home coding and ML exercise (target around 8 hours)
Onsite or virtual technical interviews with CEO, CTO, and engineering team focusing on ML system design, research thinking, and production engineering
