Backend Engineer

ABOUT THE ROLE TellySynco (by FamSync) is a family coordination dashboard that runs on Apple TV — a shared command centre for busy households. We're building a tvOS-first product with an iOS companion app, targeting the 35M+ US households that already own Apple TV. We need a Backend Engineer to own the entire server-side infrastructure: REST APIs, real-time sync, calendar integrations, and background workers. You'll work directly with the founder and have full ownership of backend architecture from day one. WHAT YOU'LL BUILD REST API Auth, household management, tasks, calendars, meals, shopping, and photos — clean, well- documented endpoints consumed by tvOS and iOS clients. Real-Time Sync WebSocket server with Redis pub/sub. Target: sub-3-second sync latency across all family devices so the TV always reflects live household state. Calendar Integrations Direct OAuth 2.0 integrations with Google Calendar, Microsoft Outlook, and iCloud CalDAV. Webhook handling, token refresh, and event normalisation to a unified internal schema.

Background Workers Calendar polling and sync jobs, push notification dispatch via APNs, RevenueCat subscription webhook processing, and scheduled reminders.
