Mobile Engineering Lead (iOS & Android)

Who We Are

NEXT Ventures is where ambition takes shape and momentum becomes movement. As a global platform revolutionising access to performance-based capital, we empower the world’s most driven individuals to rise. Through our flagship brand, FundedNext, we empower dreamers to become doers, and potential to turn into performance. With 500+ driven minds across five countries, we power a global rhythm: 220,000+ daily users from 170+ nations, each chasing greatness in their own way.

Your Role in Our Mission

As our Mobile Engineering Lead, you will be the primary technical authority behind the apps our global community relies on every day. This is a hands-on leadership role: you will own end-to-end architecture and performance engineering, build greenfield iOS and Android applications from scratch, and optimize existing architectures to stay fast and reliable under high concurrency, unstable networks and strict latency budgets. You will also lead and mentor a team of mobile engineers, setting the technical bar and building a culture of ownership and rigor, so that every user, in every market, gets a seamless experience.

How You’ll Make an Impact

- Latency and network resilience: smooth operation on high-latency, low-bandwidth, intermittent connections via aggressive caching, local-first databases and delta-sync
- High traffic and concurrency: resilient client-side state management, request batching, exponential backoff/jitter, graceful degradation during backend spikes
- 0-to-1 architecture: modular, scalable codebases with strict separation of concerns, high test coverage and zero-downtime rollouts
- App vitals: 60/120 FPS, cold start under 1.5s, no memory leaks, minimal battery and binary footprint across fragmented Android and varied iOS devices
- Security and data integrity: hardware-backed keystore/keychain encryption, certificate pinning, RASP, secure local storage

- Hands-on architecture and coding:

Design, write and review production code on native iOS and Android
- Set the bar with Clean Architecture and MVVM/MVI

- Engineering leadership:

Lead, mentor and scale the mobile team
- Drive sprints and run architectural design reviews
- Build a culture of ownership and technical rigor

- Cross-stack collaboration:

Partner with Backend, DevOps and Product
- Define API contracts (gRPC/GraphQL/REST), WebSocket/real-time pipelines and edge-caching

- Observability and release engineering:

Own mobile CI/CD and automated UI/unit testing
- Manage staged rollouts and feature flags
- Monitor crash/performance telemetry (ANRs, OOMs, P95/P99 API latency)

What You Bring

- 7+ years of professional mobile development
- 2+ years leading mobile engineers
- Proven 0-to-1 delivery of complex, high-traffic apps (hundreds of thousands to millions of MAUs)
- Deep production expertise in both native iOS and native Android
- Strong grasp of multithreading, concurrency primitives, memory lifecycle and leak detection on both runtimes

- Native iOS: Swift, SwiftUI, UIKit, Combine, Swift Concurrency (async/await, Actors), Xcode Instruments
- Native Android: Kotlin, Jetpack Compose, Coroutines, Flow, Android Profiler, Gradle optimization
- Networking and protocols: HTTP/2, HTTP/3 (QUIC), gRPC, GraphQL, REST, WebSockets, TLS/Certificate Pinning
- Local storage and sync: SQLite, Room, Realm, CoreData, SwiftData, offline-first delta sync
- CI/CD and observability: Fastlane, GitHub Actions / Bitrise / CircleCI, XCTest, Espresso, Maestro, Datadog, Sentry, Firebase Performance
