Lead Machine Learning Engineer
Polynomial Studio is an applied AI studio building products for work and life. We build in the space where work and living meet, with a simple aim: remove friction, return time, widen access, and make useful software that feels calm, fast, and fair. We are hiring an early, core team member who will become a pillar of how we build. You will work across all existing and new products. You will own the data foundation and the ML layer end to end, from instrumentation to models in production, and you will shape the standards the company follows for years. This is a startup role. Expect ambiguity, fast iteration, and high ownership. Ways of working High ownership, strong judgment, and comfort operating with ambiguity. You communicate clearly, write well, and can explain tradeoffs to non-ML teammates. You default to practical solutions, not academic perfection, and you know when to simplify. You care about product outcomes, not just model metrics.
