Senior Software Engineer I - ML Platform

Dandy is transforming the massive and antiquated dental industry—an industry worth over $200B. Backed by some of the world’s leading venture capital firms, we’re on an ambitious mission to simplify and modernize every function of the dental practice through technology. As we expand our reach globally, Dandy is building the operating system for dental offices around the world—empowering clinicians and their teams with technology, innovation, and world-class support to achieve more for their practices, their people, and their patients.

About the Role

In the past 3 years, Dandy has built the leading digital-first custom dental appliance manufacturer. As we move to the next level of scale, we are looking for a Senior Software Engineer to build the foundation of our ML Platform. You will be the bridge between SoTA Computer Vision research and production-grade reliability. You will design and scale the infrastructure that handles massive 3D datasets, orchestrates complex training pipelines, and ensures our generative models are deployed with high reliability.

What You’ll Do

• Collaborate with Machine Learning Engineers to build the ML training pipelines that process massive 3D datasets, orchestrate model training, and enable continuous model improvements.

• Streamline the ML lifecycle, from data labeling and experimentation to deployment, by optimizing internal ML components and reducing technical debt.

• Develop and maintain cloud-native systems and tooling (GCP/Kubernetes) that support Dandy’s 3D dental products in a secure, well-tested, and high-performing manner.

• Write clean, maintainable code and tests that set the standard for our internal best practices.

• Partner with stakeholders across the Engineering organization to influence long-term architectural goals and maintain a high-quality bar.

What We’re Looking For

• 5+ years of experience as a Machine Learning Engineer or Software Engineer, ideally within a high-growth startup environment.

• Deep proficiency in building and operating ML platform components, including feature stores, model registries, distributed training infrastructure, and experiment tracking.

• Experience designing and running ML systems on cloud infrastructure, including containerization and orchestration technologies such as Docker and Kubernetes, and public cloud platforms (AWS or GCP or Azure).

• Expertise in large-scale data processing, with proven experience building reliable ML data pipelines to support complex model training and evaluation.

• Experience creating and maintaining automated build, test, and deployment workflows across multiple environments (e.g., Buildkite, CI/CD pipelines).

• Strong background in observability, including implementing metrics, logging, and tracing for complex, distributed production systems.

• Ability to communicate clearly and concisely about complex architectural problems and propose iterative, pragmatic solutions.

• Experience with Python-based ML frameworks (e.g., PyTorch, TensorFlow); experience with 3D geometric computer vision is a plus
