About sync labs

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

Interview Process

we’re a small team who works hard to create outsized impact. our interview process is grounded in reality:

we're a lean team of 5 — we expect whoever we hire into this role to have a high degree of agency + maniacal urgency. we wanna make the process grounded in reality — its really hard to get a sense of how well we'd work together from a simple interview question or take home test.

here is our process:

[1] 30 mins, intro call to understand goals, evaluate mutual fit, and set up next steps.

[2] 3 hrs, technical assessment + interview loop. can solve p2p live, or offline, you choose. we understand everyone is different, and solving a real world problem in a similar environment + pace as you would normally in the role will be the best way of giving you the best chance to succeed + win.

[3] 4 hrs, irl on-site interview. we’ll fly you out to SF where we’ll work on a problem together.

from there, you’ll get an offer or decision in <24 hrs.

we want to set expectations – we work hard, work fast, and do a lot with very little. this is a team of 5 – you'd be joining an outlier team at the ground floor, and a culture of obsession is what we care about most.
