Description
We re looking for a highly skilled UI Developer with a strong background in building native applications across Windows, macOS, iOS, and Android platforms. This role requires hands-on expertise in 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. The ideal candidate also brings a strong focus on security, with the ability to integrate features like hardware-backed encryption, secure boot, and multi-factor authentication into consumer-facing applications. You ll play a critical role in creating seamless, secure user experiences across desktop and mobile devices. Requirements Bachelor s 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. Proven experience designing and building commercial-grade endpoint software at scale, with a strong emphasis on reliability, performance, and maintainability across diverse hardware and operating system environments 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. As a member of the software engineering division, you will assist in defining and developing software for tasks associated with the developing, debugging or designing of software applications or operating systems. Provide technical leadership to other software developers. Specify, design and implement modest changes to existing software architecture to meet changing needs. 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 modelling, 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.
