About the Company:

My client is a small post-Series A AI company building the training data and evaluation infrastructure frontier AI labs use to improve their models partnering with leading labs to design high-signal datasets and rigorous evaluations beyond static benchmarks. Its a lean early team where individual contributors have direct outsized impact on how the next generation of models learns.

Our culture blends the intellectual rigor of top quant shops with the speed and ownership of an early-stage startup experiencing hockey-stick growth.

We are building the training data and evaluation infrastructure that frontier AI labs use to train and improve their next-generation models. Partnering directly with leading AI research labs we design high-signal datasets and rigorous dynamic evaluations that go far beyond static benchmarks.

As a Software Engineer you will join a lean high-velocity post-Series A team where individual contributors exercise direct outsized impact. You will own end-to-end engineering initiatives across the stack build platform infrastructure and work directly with frontier labsgetting a firsthand look at model capabilities months before they hit the market.

Our culture blends the intellectual rigor of top quant shops with the speed and ownership of an early-stage startup experiencing hockey-stick growth.
