Mobile Engineer

About the role

About the Role

We're building the next generation of cross-border fintech infrastructure — powering payments, KYC, and global merchant experiences. Our merchants embed Glomo directly into their own apps, which means our mobile SDKs are the product for a large part of our business. Today those SDKs are Flutter and React Native wrappers around our web checkout. That was the right call to get to market. It is no longer enough. Over the next year we're taking mobile in-house and going native: first-class Android and iOS SDKs, and native capability inside the cross-platform ones — camera-based document capture, liveness, secure file handling, on-device identity and biometrics. You'll be the engineer who does that. You'll work alongside a senior mobile engineer, and you'll own delivery from day one.

What You'll Do

Own the mobile SDK surface

• Build and ship the Flutter and React Native SDKs — versioning, releases, changelogs,

distribution across pub.dev http://pub.dev, npm, Maven Central, and CocoaPods/SPM.

• Extend into native Android (Kotlin) and iOS (Swift) SDKs as we bring those in-house.

• Design consumer-facing SDK APIs that merchant engineers actually enjoy integrating — sane

defaults, clear errors, graceful fallbacks, honest breaking-change management.

Build native capability into payments and KYC flows

• Camera and document capture for KYC — ID capture, liveness, image quality handling on

real-world devices.

• Secure file handling — pickers, uploads, encryption at rest, temp-file hygiene.

• On-device identity — biometrics, Keychain/Keystore, secure token storage, device attestation.

• Native bridges and WebView interop — keep the hybrid surfaces correct while native capability grows underneath them.

Make releases boring

• Reproducible, automated release pipelines. No direct-to-main, no phantom builds, no "works

on my machine" release artifacts.

• Real-device E2E testing infrastructure across an Android and iOS device matrix.

• Crash-free-rate and error observability per SDK, per merchant app.

Support merchants for real

• Debug integration issues inside someone else's app, with partial information, on a device you

don't have.

• Write integration docs and sample apps that answer the question before it gets asked.

• Work directly with merchant engineering teams during integration and go-live.

What We're Looking For

Experience

• 3–5 years building and shipping production mobile applications or SDKs.

• Apps that real users used — published to the Play Store / App Store, or SDKs consumed by

external teams. Side projects and course work don't count.

• Demonstrated stability (2+ years in at least one role preferred).
