About the role
As a founding Senior Mobile Engineer at Overtone, you will build and own the mobile experience at the heart of a new kind of dating service—one centered on real-time voice, AI-driven insight, and trust. You'll be an early engineering hire with significant responsibility for mobile architecture, performance, and direction as we take our product from early to production-grade and beyond.
This is a hands-on, high-ownership role. You'll work closely with product, design, and engineering to ship a polished, voice-first consumer app on iOS.
What You'll Do
Core mobile infrastructure: Own and evolve the foundational mobile architecture for a consumer voice-first product in React Native (with native iOS code where applicable), with a focus on performance, reliability, and long-term flexibility.
Production readiness & release pipeline: Drive the work that gets us to and through App Store review—push notifications, TestFlight workflows, submission processes, and the operational discipline of maintaining a production mobile app.
Component quality & polish: Set a high bar for component architecture, animation, and interaction detail. Partner closely with our incoming designer to establish a shared design language and ensure the app feels native, intentional, and alive.
Voice & real-time experiences: Build smooth, low-latency voice interaction flows and integrate streaming audio capabilities into a seamless native-feeling experience on iOS.
AI feature integration: Bring AI-powered features to life on the client—integrating with our FastAPI backend and LLM systems to create personalized, context-aware experiences that feel intelligent without feeling robotic.
Experimentation & A/B testing: Build and own the event instrumentation and experimentation infrastructure that lets us run structured tests, measure what's working, and move with confidence.
