Fast Math is not designed to increase worksheet volume in the hope that repetition alone will accelerate students. Your responsibility is to pinpoint the precise barriers preventing students from achieving math fluency, then leverage AI to reconstruct the learning pathway until accurate computation becomes second nature.
2 Hour Learning enables students to master core academics in significantly less time than traditional school schedules. Your focus will be the Fast Math program, where you will analyze student performance metrics, platform analytics, assessment outcomes, and student work samples to uncover obstacles to fluency and fact mastery. These obstacles may include inadequate sequencing, inappropriate practice structures, absent scaffolding, insufficient feedback, or interventions that do not address fundamental misconceptions.
This role is intensely practical. You will deploy LLMs, AI-driven content creation, no-code workflows, and agentic AI systems to refine practice progressions, instructional explanations, assessments, scaffolding, and corrective interventions. Success is measured by students transitioning from labored calculation to rapid, precise, automatic execution. If you are prepared to apply AI daily to achieve quantifiable improvements in mathematical fluency, submit your application now.
Drive K-12 math fluency forward by systematically enhancing Fast Math curriculum, practice activities, assessments, scaffolding, and interventions until students perform calculations with accuracy and automaticity.
Crossover's skill assessment process combines innovative AI power with decades of human research, to take the guesswork, human bias, and pointless filters out of recruiting high-performing teams.
