Mobile Tech Lead - SDE2/3

WHY HOMERUN?

Homerun is a Series A, quick-commerce startup based out of Bangalore and one of India's fastest-growing startups building toward becoming a unicorn in the home and construction materials space. We're early-stage, assembling our founding engineering team from scratch, and shipping the mobile app that puts construction materials in customers' hands in minutes. You won't be inheriting legacy code you'll be writing the first lines that define how this system works for years.

Be the founding mobile engineer your architecture decisions are the ones the next 10 engineers inherit

Work directly with the VP of Engineering with full technical authority over mobile

Join early and help set the culture your fingerprints will be all over this company

Scale fast without layers of bureaucracy slowing you down

Work alongside a passionate, mission-driven founding team

Bangalore-based, in-person energy with a high-ownership culture

THE ROLE We're looking for a senior React Native engineer to own the mobile app end-to-end. You'll be the technical authority on all things mobile architecture decisions, code quality, performance, and shipping cadence. This is not a "build screens from Figma" role. You'll shape the mobile architecture, set up server-driven UI patterns, make infrastructure decisions, and eventually mentor junior engineers as the team scales.

WHAT YOU'LL DO

Architect and build the Homerun mobile app from the ground up React Native (Expo SDK 55, New Architecture, Hermes, Expo Router v4)

Design and implement a server-driven UI framework so the backend can control layouts, promotions, and feature rollouts without app releases

Own the entire mobile stack: Zustand, TanStack Query v5, NativeWind v4, Expo Router, and MMKV Set up the CI/CD pipeline EAS Build, EAS Update, GitHub Actions and ensure builds, linting, type-checking, and tests run on every PR

Integrate crash reporting (Sentry), analytics, performance monitoring, force update, feature flags, and deep linking from Day 1

Build with security in mind: certificate pinning, encrypted storage, no secrets in the JS bundle, jailbreak/root detection

Write tests (Jest, RNTL, Maestro) and enforce a culture where untested code doesn't get merged Collaborate with the backend team (Go + PostgreSQL + Redis on GCP) to shape API contracts and ensure a fast, reliable mobile experience

YOU SHOULD HAVE

37 years of professional experience building and shipping React Native apps to production (App Store + Play Store)

Deep familiarity with the modern RN ecosystem New Architecture (Fabric, TurboModules, JSI), Expo managed workflow, Hermes, file-based routing

Strong TypeScript skills strict mode, generics, discriminated unions, not just any everywhere

Hands-on experience with at least two of: Zustand, TanStack Query, NativeWind/Tailwind, React Hook Form + Zod

Experience setting up CI/CD for mobile (EAS Build, Fastlane, or similar), OTA update strategies, and build profiles for dev/staging/prod

Working knowledge of mobile performance optimization cold start times, JS thread FPS, bundle size, image loading, list virtualization

Understanding of mobile security basics: token storage, certificate pinning, ProGuard/R8, no PII in logs

Comfort with ambiguity, moving fast, and owning outcomes not just tasks

BONUS POINTS Built server-driven UI systems Prior experience in quick-commerce, logistics, or high-frequency transactional apps Familiarity with Go, PostgreSQL, or GCP Experience with Sentry, Maestro/Detox for E2E Previously worked at an early-stage startup
