Technical Lead

Looking 8+ Years of experience Technical Lead to drive macOS and Windows platform of a cross-platform security product written in C/C++, supporting hardware token and smart card authentication.

With strong knowledge of Windows and macOS architecture end-to-end — from low-level USB device communication through packaging, signing, and CI/CD delivery.

A solid understanding of cryptographic algorithms — including classical schemes (RSA, ECC, AES) and emerging Post-Quantum Cryptography (PQC) standards such as ML-KEM and ML-DSA.

📋 KEY RESPONSIBILITIES

Framework & Platform Ownership: Own Windows and macOS-specific layers including native framework bundles, system daemons, menu-bar applications, and CryptoTokenKit (CTK) extensions.

USB & IPC: Lead USB device enumeration and management via IOKit, IPC via UNIX domain sockets, and daemon lifecycle integration.

Build, Packaging & Signing: Maintain and evolve the Xcode build system, packaging pipeline (.pkg,.dmg), and code signing/notarization workflows using Apple Developer ID certificates.

CI/CD Pipeline: Own the Windows and macOS CI/CD pipeline, build, package, sanity test, and artifact deployment stages.

Technical Leadership: Mentor engineers, conduct architectural reviews, and collaborate with Windows and Linux platform leads for cross-platform consistency.
