You will also play a pivotal role in evolving our task orchestration infrastructure infrastructure, helping us transition from a centralized, generic experience into highly tailored, purpose-built solutions for specific product domains.

You will tackle complex full-stack challenges, from designing scalable backend APIs and rule-evaluation engines for custom automations, to crafting intuitive frontend UX for our domain-specific task interfaces and workflow builders. Beyond core platform work, you will be part of a team that directly shapes broader product experiences - including leveraging AI to streamline user workflows and supporting the continuous evolution of our productivity tools in web and mobile.
