We are Annam Software – a 100 % foreign-owned product house building the next-generation Omnicasa property CRM for the European market. Our legacy web (Vue 2) and Windows desktop apps still serve 3000+ agents, but we’re rebuilding everything. To move fast and smart we need a Product Manager who lives inside PostHog, turns events into insights, and tells us exactly which features make the cut for MVP-1. If you love SQL, funnels, cohorts, and saying “let the data decide”, read on.
