About The Position

Vizcom is an AI design tool for industrial and product designers, enabling them to go from sketch to render, 3D model, and video in a single platform. The company is seeking a Senior Product Engineer to enhance Vizcom's capabilities by integrating product decision-making features, including review, feedback, and context, directly within the platform. This role involves developing a faster canvas, enabling real-time collaboration, and integrating an AI agent that operates within the canvas. The engineer will be responsible for end-to-end ownership of features, from scoping with design to building frontend and API components, shipping, and iterating based on user feedback. The ideal candidate will have a passion for both the user experience and code quality.

Requirements

5+ years of experience shipping complex frontend applications using React and TypeScript, focusing on deep state management and intricate interactions rather than simple CRUD operations.
Demonstrated experience with Canvas, WebGL/WebGPU, or a custom rendering engine, including performance optimization and debugging.
Comfort and capability across the full stack, including designing GraphQL schemas, writing Postgres migrations, and independently shipping features.
Strong product taste and the ability to push back on specifications, prototype solutions, and make informed decisions about user experience.
Proficiency in using AI coding tools while maintaining ownership and verification of all code.
A focus on owning outcomes rather than just completing tickets.
Experience with performance optimization, including profiling and debugging frame rates and memory usage.

Experience working with Electron or other desktop application frameworks.
Personal experience with sketching or design, or close collaboration with industrial designers.

Responsibilities

Profile frame time, memory, and texture decode paths to maintain and improve application performance, especially for large files and extended sessions.
Develop pro-grade 2D tools, including brush engines, layer masks, selections, and transform/warp functionalities, ensuring a high-quality user experience comparable to industry-leading software.
Build the user interface for a create-review-present workflow, integrating an AI agent that can interact with the entire workbench to streamline AI-driven workflows (Modify, Regions, Animate, 3D).
Develop features for project management and collaboration, including project organization above files, real-time multiplayer functionality, commenting, review systems, and enterprise-level roles and permissions.
Implement and enhance 3D rendering capabilities in the browser using Three.js/WebGL as first-class canvas elements, serving as inputs for generation and review processes.
Write end-to-end tests, add instrumentation for monitoring, and take ownership of features in production.
