"The AI company that's revolutionizing Hollywood"
Flawless is transforming Hollywood with assistive AI. Our tools empower filmmakers to edit, localize, and refine performances while preserving artistic intent.
Designed to support, not replace, artists, our technology expands what is possible on screen and gives creators freedom to tell stories with greater impact and reach audiences in new ways. From enabling seamless multilingual releases to eliminating the need for costly reshoots, Flawless solves critical challenges that slow down productions and limit distribution.
We are also setting the standard for ethical AI in entertainment. Our Artistic Rights Treasury (A.R.T.) is a rights management solution that protects artists and rights holders, ensuring that innovation moves forward with transparency and respect for creative ownership.
As a Principal Engineer in our Product Engineering team, you will be both the hands-on technical anchor for our DeepEditor product and a principal-level leader influencing work across the department. Day to day, you’ll embed directly within the team - writing code, solving problems alongside other engineers, and unblocking delivery - while also guiding architecture, strategy, and technical standards for DeepEditors long and short form offerings. You’ll mentor senior engineers, shape key technical decisions, and ensure our products meet the highest standards of quality, performance, and innovation.
Our core technologies are TypeScript, React, and Python. We’re looking fora strong generalist that is happy to work across the stack to deliver robust, scalable solutions.
