ABOUT THE PROJECT
Our client, an international multi-entity group, is building a security-critical, privacy-first information system on its own on-premise infrastructure: hardened mobile and desktop applications, hardware-key authentication, legally isolated data for each group entity, and self-hosted finance and AI capabilities.
The programme is delivered by a senior, multi-disciplinary team working in two-week agile sprints, with compartmentalised access and a strong culture of security by design.
WORK ARRANGEMENT
This is a remote position: you will work from home, from Madagascar. No attendance at DI-Africa's offices is required.
THE ROLE
Lead the development of the client's hardened Android application: a Kotlin native shell with a secured WebView, deep integration with the device VPN layer and a privately signed release channel.
KEY RESPONSIBILITIES
● Design and build the Kotlin application shell and the WebView bridge to the shared TypeScript/React front end.
● Harden the application and its WebView policy on a security-focused Android OS (GrapheneOS).
● Integrate the OS-level VPN lockdown and hardware-key (NFC WebAuthn) authentication hand-off.
● Own build, signing and private update channel scripts, with fail-closed behaviour by design.
● Optimise battery and idle behaviour on a high-latency overlay network.
TECHNICAL ENVIRONMENT
● Kotlin (primary), WebView bridge to TypeScript/React, build and signing scripts.
● Google Pixel devices running GrapheneOS, I2P as OS-level VPN.
● Authentik identity provider, NFC WebAuthn / FIDO2.
