Build workflows that complete supported actions, clearly explain missing information, and resume when information arrives
Collaborate with desktop engineers on automations, tasks, and approvals in the Electron app
Help non-technical teammates write evaluations and review their work
Participate in a lightweight on-call rotation for client-facing automations
Join recruiting-lead calls, understand real workflows, and design solutions reusable across clients
Ship fixes, scenario evaluations, end-to-end automations, workflow libraries, and general-purpose tools according to defined milestones
