Senior Developer Cross-Platform User Interfaces

Role Overview: You are a highly skilled UI Developer with a strong background in building native applications across Windows, macOS, iOS, and Android platforms. Your role involves utilizing platform-specific development tools and languages such as C/C++, WinAPI, Cocoa, Swift, Kotlin, and Android NDK to deliver intuitive, high-performance user interfaces tailored to each ecosystem. You play a critical role in creating seamless, secure user experiences across desktop and mobile devices. Key Responsibilities: - Design and develop secure, high-performance native user interfaces for Windows, macOS, iOS, and Android platforms. - Leverage platform-specific technologies (e.g., WinAPI, Cocoa, Swift, Kotlin, Android NDK) to deliver responsive, intuitive UI experiences. - Integrate hardware-backed security features including Trusted Platform Module (TPM), Apple Secure Enclave, and Android Keystore for secure boot, attestation, and encrypted storage. - Implement cryptographic algorithms and secure communication protocols to protect data at rest and in transit. - Build and support robust authentication mechanisms, including MFA, biometrics (Face ID, Touch ID, fingerprint), and token-based access. - Collaborate with security architects and engineers to define and implement secure software architecture. - Conduct code reviews, threat modeling, and security assessments to proactively identify and address vulnerabilities. - Stay informed on emerging threats, CVEs, and platform security updates, ensuring applications are always a step ahead. - Partner closely with product managers, UX designers, and backend engineers to deliver cohesive, high-quality apps on time. - Mentor junior developers in secure coding practices, cryptography, and platform-specific development techniques. Qualification Required: - Bachelors degree in Computer Science, Engineering, or a related field. - Proven experience developing native applications for Windows and at least two additional platforms (macOS, iOS, Android). - Proficient in C/C++ and platform-native development frameworks such as WinAPI, Cocoa, Swift, Kotlin, and Android NDK. - Strong knowledge of TPM, Secure Enclave, and Android Keystore, with experience integrating these technologies for secure storage and authentication. - Hands-on experience with cryptographic libraries such as OpenSSL, CryptoAPI, and CommonCrypto. - Familiarity with authentication protocols like OAuth2.0, OpenID Connect, FIDO, and optionally Kerberos, SAML, and LDAP. - Deep understanding of Windows and macOS internals, including system architecture, low-level APIs, and built-in security features such as BitLocker, User Account Control (UAC), Windows Defender, and macOS System Integrity Protection (SIP), Gatekeeper, and FileVault. - Experience using mobile security testing tools such as AppScan, Burp Suite, or Mobile Security Framework (MobSF). - Strong attention to detail with a passion for writing secure, efficient, and maintainable code. - Excellent communication skills and a collaborative mindset, with the ability to mentor and inspire peers.,
