A new CTO has just joined and is building out a small, elite engineering team from the ground up. This is the first senior IC hire, with significant influence over architecture, technical direction, and product innovation. You'll operate in a true 0?1 to 1?N environment: * Early stage: rapid prototyping, experimentation, and validation * Scaling phase: productionizing systems and collaborating with a distributed team This is an evergreen mandate to hire exceptional engineers (multiple hires planned) - the bar is extremely high.
