Luzia is a consumer AI assistant reaching 60M+ users in under two years, built on a modern mobile stack (iOS, Android, Swift, SwiftUI) paired with cloud data infrastructure (Redshift, BigQuery, Snowflake, AWS, GCP). The hiring mix—dominated by senior engineers and designers, minimal posting velocity—reflects a company past early-stage hiring chaos, now focused on hardening core systems and shipping mobile-first experiences. Active projects center on offline-tolerant WhatsApp flows, backend scaling for AI workloads, and differentiating the assistant UX as LLMs commoditize.
