The Senior Software Engineer focuses on developing advanced systems to detect and prevent spoofing attacks during biometric authentication processes. This role involves utilizing machine learning and deep learning techniques to create models capable of distinguishing between genuine human interactions and fraudulent attempts.

• Develop and design liveness detection systems that utilize AI algorithms to differentiate between real and fake biometric data including analyzing facial features, eye movements, and other physiological indicators.
• Build and optimise deep learning models specifically for liveness detection, selecting appropriate algorithms, conducting experiments, and tuning parameters to enhance accuracy and reliability.
• Identify and extract features from biometric data that are crucial for detecting spoofing attempts, including texture analysis, motion-based detection, and 3D depth analysis.
• Collaborate with data scientists to collect, clean, and preprocess large datasets required for training liveness detection models, ensuring data integrity and suitability.
• Implement machine learning algorithms capable of processing real‑time biometric data to detect inconsistencies indicative of spoofing attempts, integrating multimodal approaches such as facial recognition, fingerprint scanning, and iris recognition.
• Conduct rigorous testing of liveness detection systems to ensure performance in real‑world scenarios.
• Validate models against various spoofing techniques to ensure robustness.
• Deploy liveness detection systems into production environments, ensuring scalability and high performance.
• Continuously monitor system outputs to identify any issues with accuracy or efficiency.

• Bachelor’s degree in computer science, mathematics, or a related field.
• In‑depth understanding of machine learning frameworks such as Tensor Flow, Keras, or PyTorch.
• Experience in developing deep learning models is essential.
• Proficiency in programming languages such as Python, Java, or R for model development and algorithm implementation.
• Problem‑solving abilities with a solid grasp of statistics, probability theory, and data analysis techniques.
• Ability to work effectively with cross‑functional teams (including data scientists, software engineers, and product managers) to achieve common goals.
• Experience in similar roles focusing on anti‑spoofing or biometric security systems (e.g., NIST ISO/IEC 30107 or FIDO).
• Innovative mindset with a passion for continuous learning and keeping up with the latest advancements in AI and machine learning technologies.
