If you have personally made over $100,000 via trading (manual / algo), or have improved a trading strategy significantly, please email [email protected] directly to have your application fast-tracked. We also fast track candidates who are currently at top quantitative trading firms.

Founded by a team of Cambridge ex quant-traders and researchers, with over 5 trillion tokens served per month to 5 million users, Chai has quickly established itself as the fastest-growing AI startup in Palo Alto.

We are looking for someone to run, optimize, and improve our AI platform, with the north-star metric being day 30 retention. You will be directly responsible for tasks which lead to a 50% improvement to our platform-wide retention. You will also be free to come up with other creative ways that we can monetize.

Who we are looking for

- Someone with an established track-record of delivering results which matter to the company

- Someone who has a deep understanding of the ML development cycle, focusing on iteration speed and identifying bottlenecks

- Someone who is goal oriented and driven. You must be comfortable being given a goal and doing whatever is necessary to achieve the goal

- Profficient in Python, Tensorflow or PyTorch

Here's why we might not be the right fit for you

• We work hard and have a high-velocity environment with lots of growth opportunities.

• We value exceptional performance and continuous improvement. We believe that if you aren't constantly learning, you aren't growing.

• You will be responsible and accountable for making high-impact decisions that determine Chai's future

Here are the top 2 reasons why you should join us

• Exponential growth. 1 Million MAU. Join the team that gets us to 100 million MAU

• Craftsmanship. Build something beautiful

We are happy to sponsor visas for the right candidates.
