## Description

We're looking for a founding engineer to own the software at the center of Taya: the app people open every day to capture, search, and relive their memories. We have a working iOS app today. Your job is to take it from working to indispensable.

You'll work directly with Elena, with no layers and no process, and the decisions you make now will define the product for years. This is a software-first role for someone who thinks in products, not tickets, and who measures success by whether people keep coming back., * Own and evolve the iOS app, the daily driver for someone's entire memory archive

 * Own onboarding and the first-run experience: get people to their first real memory fast
 * Own retention: define the metrics that matter, then build the features and loops that move them
 * Build AI-powered search and retrieval that surfaces the right moment
 * Improve the capture experience: tap-to-capture, backgrounding, audio handling
 * Own sync between the wearable and the app over BLE
 * Integrate AI services and a managed backend (Supabase or similar)
 * Own a privacy architecture users can trust, on-device wherever possible
 * Work with Elena across product, design, and GTM to ship, learn, and iterate
