Senior React Native Engineer

• *HIRING!!
• *SENIOR REACT NATIVE ENGINEER [TEAM LEAD]
• *ROLE TYPE**

Full time || USD

• *ABOUT THE ROLE**

We are hiring a

• *Senior React Native Developer / Mobile App Owner**

to take full ownership of an existing

• *mission-critical React Native app (pure RN, no Expo)**

used daily by customers at scale. The app started as an MVP and grew into a large production system, with significant parts built without React Native best practices.

The core focus is

• *refactoring and stabilizing**

the current codebase while continuing to ship features. This person will be the

• *only React Native developer in the company**

, responsible for everything mobile end-to-end: architecture, releases, app store management, production issues, and long-term code health.

Because this app operates in real time and supports large-scale usage, the client is

• *extremely selective**

and is not open to candidates who need to “learn on the job.”

• *RESPONSIBILITIES
• App Ownership (End-to-End):**

Own the mobile app fully—development, releases, monitoring production issues, and ongoing maintenance across iOS and Android.

• Major Refactor & Stabilization:

Refactor the existing app toward best practices (architecture, state management, performance, maintainability) without breaking real-world workflows.

• Offline-First Architecture (Critical):

Design and implement reliable offline-first behavior to handle real connectivity issues (sync strategies, local persistence, conflict resolution, graceful degradation).

• Geolocation / GPS (Critical):

Implement and maintain geolocation functionality including GPS integration, background location updates, permissions handling, and app lifecycle behavior.

• Native Capability Integration:

Work confidently with native modules when required (Swift/Kotlin-level integrations if needed, or bridging libraries).

• Performance & Reliability:

Diagnose and resolve bottlenecks (rendering, memory, network, background execution) and improve app stability for production scale.

• Backend Integration:

Integrate REST APIs and real-time events to support mission-critical tracking and operational workflows.

• Testing & Release Quality:

Maintain strong release discipline—testing strategy, regression prevention, and production-readiness checks.

• Collaboration & Review:

Work with the internal tech lead and team for reviews, but remain the primary mobile execution owner.

• *TECHNICAL REQUIREMENTS
• *Must Have: Non-Negotiable
• Senior React Native engineer (no learning curve):

5+ years mobile, 3+ years React Native, with proven ownership of production apps.

• Pure React Native (no Expo):

Comfortable working directly with React Native CLI and native build pipelines.

• Offline-first experience:

Demonstrated experience building and architecting

• *offline-first mobile apps**

(local storage, sync, resilience).

• Geolocation / GPS experience:

Real experience implementing

• *geolocation + GPS**

, including background behavior and permission flows.

• Production-grade debugging:

Strong ability to troubleshoot and stabilize complex, legacy RN codebases.

• iOS + Android delivery:

Comfortable managing releases, store submissions, and production issues across both platforms.

• *Strong Technical Foundation
• TypeScript + modern React patterns (hooks, modular architecture, state management).
• Deep understanding of RN lifecycle, platform differences, and background execution constraints.
• Comfortable integrating REST APIs and real-time updates.
• *Nice-to-Have
• Experience with native development exposure (Swift/Kotlin) or heavy native-module work.
• Familiarity with Firebase/FCM/APNs (especially for notifications).
• Basic E2E testing exposure (Detox/Appium) and solid unit/integration strategy.
• *CLIENT EXPECTATION
• Owner mindset:**

This is “their app”—they own stability, releases, and production issues.

• No hand-holding:

Must already have offline-first + geolocation experience (cannot learn during the role).

• High reliability:

Strong QA mentality and careful change management due to production scale.

• Clear communicator:

Works well remotely, documents decisions, flags risks early, and keeps stakeholders aligned.

• Long-term fit:

If strong (like their current long-term engineers), they want this person to stay long-term.

• *INTERVIEW / SELECTION PROCESS**
• Initial call with client
• Take-home assignment
• Review call of take-home
• Interview with engineering lead
• Interview with CTO
• Final interview with product manager
