SDK Architecture and Engineering :\n\n- Design, architect, and evolve scalable, secure, and high-performance native Android and iOS SDKs.\n\n- Establish SDK architecture, modularization, public API design, versioning strategies, and backward-compatibility standards.\n\n- Lead the development of reusable SDK components using Kotlin/Java, Android NDK/C++ where required, Swift, and Objective-C.\n\n- Optimize SDK binary size, cold-start latency, memory footprint, initialization overhead, and runtime performance.\n\n- Design integration patterns that minimize implementation effort and compatibility issues for banking and fintech partners.\n\n- Define SDK integration contracts, configuration models, error handling, and developer-facing APIs.\n\n- Develop sample applications, integration documentation, migration guides, and diagnostic tooling.\n\n- Review code and architecture proposals, enforce engineering standards, and mentor junior and mid-level engineers.\n\n2. Advanced Device Security and Anti-Fraud:\n\n- Design and implement robust root/jailbreak detection and identify emulators, debuggers, hooking frameworks, and runtime instrumentation.\n\n- Develop and harden detection mechanisms against tools and techniques such as Frida, Xposed, Cydia Substrate, and related injection frameworks.\n\n- Architect RASP capabilities covering runtime integrity verification, anti-tampering, anti-repackaging, obfuscation, and suspicious execution detection.\n\n- Design privacy-conscious device fingerprinting mechanisms that generate reliable signals for fraud detection and risk assessment.\n\n- Evaluate bypass techniques, perform security-focused testing, and proactively strengthen detection and mitigation mechanisms.\n\n- Balance detection effectiveness with false-positive rates, device compatibility, performance, and legitimate user experience.\n\n- Collaborate with security research, fraud analytics, and machine learning teams to integrate device risk signals into fraud detection systems.\n\n- Define approaches for securely collecting, validating, and transmitting device security telemetry.\n\n3. Android and iOS Platform Security :\n\n- Lead security-focused implementation across Android and iOS, with deep expertise in at least one platform and working knowledge of the other.\n\n- Integrate and evaluate Android Keystore, Play Integrity API, iOS Keychain, Secure Enclave, and App Attest.\n\n- Design secure SDK-to-server communication flows involving token exchange, certificate pinning, replay protection, and appropriate cryptographic controls.\n\n- Implement secure local storage, sensitive-data handling, integrity verification, and platform-specific security controls.\n\n- Evaluate low-level platform capabilities and Android NDK/C++ or native iOS techniques where they improve security.\n\n- Stay current with OS security changes, platform restrictions, new attack vectors, and evolving mobile security best practices.\n\n- Assess security trade-offs and recommend practical mitigations for production environments.\n\n4. Quality Engineering and Production Ownership :\n\n- Define SDK quality standards covering crash-free rate, ANR rate, startup performance, memory usage, compatibility, and release stability.\n\n- Establish comprehensive testing strategies across real devices, OS versions, manufacturers, and application configurations.\n\n- Design automated unit, integration, compatibility, and regression testing for SDK components.\n\n- Build and improve CI/CD pipelines for SDK compilation, security checks, automated testing, artifact publishing, and staged rollouts.\n\n- Lead root-cause analysis of complex production issues, security incidents, and partner integration failures.\n\n- Own release readiness, version rollout strategies, regression prevention, and production stability improvements.\n\n- Establish monitoring, diagnostics, and support processes for L2/L3 partner integration issues.\n\n5. Partner Engineering and Cross-Functional Collaboration :\n\n- Work directly with banking, fintech, and enterprise partners to resolve complex SDK integration and compatibility challenges.\n\n- Lead technical discussions, partner onboarding, integration validation, and certification activities.\n\n- Collaborate with backend engineering teams on secure APIs, authentication flows, telemetry ingestion, and device risk assessment.\n\n- Partner with fraud and ML teams to improve the quality and usefulness of device-derived risk signals.\n\n- Coordinate with security teams on threat modeling, vulnerability assessment, remediation, and security validation.\n\n- Translate partner requirements and production findings into SDK roadmap improvements.\n\nRequired Skills and Qualifications :\n\n- 6 - 8 years of hands-on native mobile engineering experience.\n\n- Strong expertise in at least one platform :\n\n1. Android : Kotlin, Java, Android SDK, Gradle, and preferably NDK/C++.\n\n2. iOS : Swift, Objective-C, Xcode, and platform-native security frameworks.\n\n- Proven experience building, releasing, and maintaining production SDKs or libraries consumed by external developers or partner applications.\n\n- Strong understanding of SDK architecture, public API design, semantic versioning, dependency management, and backward compatibility.\n\n- Hands-on experience with mobile security controls, including root/jailbreak detection, anti-tampering, and code obfuscation.\n\n- Practical knowledge of RASP, runtime integrity checks, hooking/injection detection, and anti-repackaging techniques.\n\n- Experience with device fingerprinting or mobile device risk signals.\n\n- Strong understanding of Android Keystore and Play Integrity API, and/or iOS Keychain, Secure Enclave, and App Attest.\n\n- Experience implementing secure communication controls, including certificate pinning, secure token handling, and replay protection.\n\n- Demonstrated ability to debug complex issues across physical devices, manufacturers, and OS versions.\n\n- Experience with CI/CD, automated testing, production diagnostics, and SDK release management.\n\n- Strong technical leadership, code review, problem-solving, and cross-functional communication skills.\nSkills\nNative Apps, iOS, Android, Java, Kotlin,
