Computer Software
Responsibilities
Lead the architecture and build of our iOS and Android apps (from foundation to launch) within the first 90 days
Translate our web MVP into mobile-native experiences (navigation, gestures, system UI patterns, performance)
Ship to production: App Store / Play Store submissions, compliance, release management, and iteration cycles
Optimize performance and reliability across audio recording/playback, streaming or real-time interactions, and AI response rendering
Partner closely with design and product to implement high-craft UI and smooth motion/animations
Establish engineering best practices: code quality, testing strategy, CI/CD, analytics instrumentation, crash reporting, and monitoring
Collaborate with backend/AI engineers to define API contracts and ensure robust mobile-friendly behavior (latency, retries, offline/poor-network handling)
Protect user trust by implementing privacy-conscious permissions, secure storage, and thoughtful edge-case handling
Qualification
Required
3+ years building and shipping production mobile apps, ideally consumer-facing products with high polish
Experience shipping iOS and Android via one of the following: Cross-platform: React Native (preferred) or Flutter, or Native: Swift/SwiftUI + Kotlin (or strong experience in one with ability to ramp quickly on the other)
Proven ability to take products from 0 to 1 (or own major greenfield surfaces) and operate autonomously
Strong product judgment: you can make smart tradeoffs under ambiguity and optimize for user experience
Comfort working from an existing product (web) and re-architecting where needed rather than doing a 1:1 port
Performance-minded, with experience improving startup time, memory usage, animation smoothness, and perceived latency
Preferred
Experience with audio, speech, or AI-powered apps (recording pipelines, transcription, streaming, on-device constraints)
Familiarity with App Store / Play Store review processes, privacy policies, permissions, and release best practices
Early-stage startup experience (fast iteration, ownership, pragmatic decision-making)
Benefits
Meaningful early-stage equity
