iOS Developer

We are looking for an experienced iOS Developer to help build a platform-specific module that wraps the OpenVPN3 C++ client and integrates with a cross-platform Flutter plugin. You’ll be responsible for implementing core VPN functionality (connect, reconnect, disconnect, status callbacks) and delivering the module as an XCFramework.

Responsibilities:

• Integrate the OpenVPN3 C++ client into an iOS environment using Objective-C++ and Swift.

• Build an XCFramework that wraps native VPN functionality.

• Interface with the iOS NetworkExtension framework to manage VPN configuration and lifecycle.

• Implement TunBuilderBase to create a tunnel using PacketTunnelProvider.

• Handle user permissions and entitlements for VPN capabilities.

• Expose required methods to Flutter via a platform channel.

• Collaborate with Android and Flutter developers to ensure consistency across platforms.

Required Skills:

• Strong experience in iOS development using Swift and Objective-C++.

• Deep understanding of Swift/C++ interoperability.

• Prior experience with network programming or VPN-related features on iOS.

• Familiarity with Network Extension APIs, particularly NEVPNManager and PacketTunnelProvider.

• Experience compiling and linking C++ libraries (.a or .xcframework) on iOS.

• Knowledge of configuring app entitlements and managing VPN permissions.
