Senior Mobile Engineer

Department: Engineering

Location: New York City

Compensation: $175K – $225K • Offers Equity

Employment Type: FullTime

Your 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.

• Platform quality & performance: Own the mobile experience end-to-end—app state management, offline handling, and the polish that makes a consumer app feel trustworthy and alive.

• Security & privacy by design: Build with user data protection and privacy as first-class concerns, especially in a product where people share deeply personal information.

• Technical ownership: Help set mobile engineering standards, make architectural tradeoffs, and establish a culture of pragmatic, high-quality engineering.

Who You Are

• Senior experience as a mobile engineer on consumer-facing products

• Strong React Native experience; native iOS knowledge a plus

• A track record of taking products from early-stage to production-grade, including navigating App Store processes and release pipelines

• Experience with push notification systems and mobile platform operations

• A systems thinker who also holds a high bar for UI quality, animation, and interaction detail

• Experience building component libraries with strong attention to polish and native feel

• Experience with event instrumentation, analytics pipelines, and A/B testing frameworks on mobile

• Experience integrating real-time or streaming features—voice, video, audio, or similar

• Comfort working across the full mobile stack, from UI components to API integration (FastAPI/PostgreSQL)

• Strong judgment around performance, security, and reliability in high-trust consumer products

• Familiarity with LLM-powered products and AI feature integration on the client side

Nice to have:

• Experience with native iOS development

• Experience with on-device ML

• Experience with real-time audio/voice SDKs

• Experience at an early-stage startup or in a dating/social product

Compensation & Benefits
