We recently raised a $10.5M seed round led by Andreessen Horowitz, with participation from Y Combinator and operators from companies including OpenAI, Legora, and Lovable.

ABOUT THE ROLE You'll be one of the first hires outside the founding team - four ex-QuantumBlack engineers, now building Stilta. Your decisions will shape the product for years.
