Senior Software Engineer – Productivity App About the Role Our client is an early-stage, founder-led company building a novel productivity application designed to bridge the gap between daily execution and long-term personal goals. Rather than acting as a standard standalone task manager, the platform connects daily priorities directly to macro goals through high-performance desktop workflows. We are seeking a Senior Software Engineer to own technical decisions, architect core systems, and lead hands-on development as the product transitions into its next phase. This is a fully remote, high-ownership role working directly alongside the founder. We place a high premium on end-to-end systems architecture and fundamental software design. In an era where AI tools streamline routine coding tasks, we are specifically looking for a senior engineer who brings deep architectural vision, system-level problem solving, and production rigor to the table. Technical Stack & Architecture * Target Platforms: macOS Desktop (Primary / First), followed by Windows, Mobile (Expo/React Native), and Web. * Frontend / Desktop: Electron, React, TypeScript, Vite, Tailwind CSS. * Backend: Node.js / TypeScript, Hono, Drizzle ORM. * Database, Sync & Auth: Local-first SQLite, PowerSync, PostgreSQL (Neon), Clerk. * Infrastructure: Dockerized API hosted on dedicated Linux VPS, Neon Postgres, PowerSync Cloud.
