Job Description
This is a hybrid, full-time opportunity with a fast-growing startup at the intersection of AI, automation, and 3D design. The team builds intelligent desktop and web tools that streamline how digital dental models are created, reducing manual design work by up to 95% through a combination of AI integration, 3D geometry processing, and real-time visualization.
You'll work across a modern stack that blends Electron, React, and AWS serverless backend services, helping build powerful, production-ready tools used by dental labs and clinicians worldwide. This role is perfect for a developer who enjoys working across multiple layers of a system - from 3D rendering to backend APIs - and wants to solve complex, technical problems that directly impact real-world outcomes.
Candidates must be able to commute to the El Segundo office two days per week, with remote flexibility for the remaining days.

Strong proficiency in JavaScript and React
Experience developing and maintaining Electron desktop applications (file system access, local storage, JSON config/state management)
Working knowledge of AWS serverless technologies (Lambda, DynamoDB, S3)
Familiarity with Three.js and foundational 3D geometry concepts (STL files, point clouds, transformations)
Ability to work confidently across frontend, backend, and desktop codebases
Bachelor's degree in Computer Science, Software Engineering, or a related field
Must reside within commuting distance of El Segundo, CA
U.S. citizenship required

Desired Skills & Experience
Experience designing and refining UI/UX interfaces
Background in Python or experience with 3D/CAD software
Knowledge of geometry processing, including mesh manipulation or point cloud optimization
Interest in CAD systems, medical device technology, or workflow automation
Strong communication skills and comfort working in small, fast-moving teams

What You Will Be Doing
Tech Breakdown
60% Electron + React application development
25% Backend development using Node.js and AWS (Lambda, DynamoDB, S3)
