About sync.

at sync. we're making video as fluid and editable as a word document.

how much time would you save if you could record every video in a single take?

no more re-recording yourself because you didn't like what you said, or how you said it.

just shoot once, revise yourself to do exactly what you want, and post. that's all.

this is the future of video: AI modified >> AI generated

we're playing at the edge of science + fiction.

our team is young, hungry, uniquely experienced, and advised by some of the greatest research minds + startup operators in the world. we're driven to solve impossible problems, impossibly fast.

our founders are the original team behind the open sourced wav2lip — the most prolific lip-sync model to date w/ over 9k+ GitHub stars.

we’re at a stage today in computer vision where we were w/ NLP two years ago — have a bunch of disparate, specialized models (eg. Sentiment classification, translation, summarization, etc), but LLMs (a generalized large language model) displaced them.

we’re taking the same approach – curating high quality datasets + training a series of specialized models to accomplish specific tasks, while building up to towards a more generalized approach for one model to rule them all.

post batch our growth is e^x – we need help asap to scale up our infra, training, and product velocity.

we look for the following: [1] raw intelligence [2] boundless curiosity [3] exceptional resolve [4] high agency [5] outlier hustle

About the role

Skills: TypeScript, OpenGL

About sync.

sync. is a team of artists, engineers, and scientists building foundation models to edit and modify people in video. Founded by the creators of Wav2lip and backed by legendary investors, including YC, Google, and visionaries Nat Friedman and Daniel Gross, we've raised 6 million dollars in our seed round to evolve how we create and consume media.

Within months of launch our flagship lipsync API scaled to millions in revenue and powers video translation, dubbing, and dialogue replacement workflows for thousands of editors, developers, and businesses around the world.

That's only the beginning, we're building a creative suite to give anyone Photoshop-like control over humans video – zero-shot understanding and fine-grained editing of expressions, gestures, movement, identity, and more.

Everyone has a story to tell, but not everyone's a storyteller – yet. We're looking for talented and driven individuals from all backgrounds to build inspired tools that amplify human creativity.

About the role

We're seeking an exceptional senior to staff level frontend engineer who can architect and build new ways of editing video with AI.

We're not looking for specialists, rather driven problem solvers who can move seamlessly between crafting intuitive UIs and engineering browser capabilities to their limits. You'll work directly with the creators of Wav2lip, tackling challenges from real-time video processing to making tools people can't live without.

Our technical stack

Our creative suite is built with TypeScript and React , with NextJS and tRPC powering our API infrastructure. You'll own the development of our core video processing engine, bringing real-time editing capabilities directly to the browser through WebGL and WebAssembly , and maximally leveraging our models through our core AI platform.

What you'll do

• Create fluid, responsive interfaces that make complex AI capabilities feel intuitive

• Build high-performance video processing pipelines that run entirely in the browser

• Ship features that define new standards for AI video creation

• Work closely with research to rapidly prototype and productize new model capabilities

• Drive improvements in frontend architecture and development practices

What you'll need

• 5+ years building complex web applications, with deep React/TypeScript expertise

• Strong background in video/media technologies (WebGL, Canvas, WebAssembly)

• Track record of shipping 0-to-1 features that users love

• Experience optimizing performance in demanding frontend applications

• Ability to move fast, iterate from user feedback, and execute on tight deadlines

• Obsession with craft and user experience

• Strong team player who thrives in highly collaborative, fast-moving environments

Our goal is to keep the team lean, hungry, and shipping fast.

These are the qualities we embody and look for:

[1] Raw intelligence: we tackle complex problems and push the boundaries of what's possible.

[2] Boundless curiosity: we're always learning, exploring new technologies, and questioning assumptions.

[3] Exceptional resolve: we persevere through challenges and never lose sight of our goals.

[4] High agency: we take ownership of our work and drive initiatives forward autonomously.

[5] Outlier hustle: we work smart and hard, going above and beyond to achieve extraordinary results.

[6] Obsessively data-driven: we base our decisions on solid data and measurable outcomes.

[7] Radical candor: we communicate openly and honestly, providing direct feedback to help each other grow.
