Role and Responsibilities:


  • Support the implementation of security controls and processes focusing on a broad range of systems, including core trading infrastructure, cloud services, and business applications across both Windows and Linux environments
  • Collaborate with engineering and product teams to integrate security into product design and development, applying your experience in securing large-scale software systems in a fast-moving environment
  • Contribute to the development and maintenance of a secure software development lifecycle (SDLC) with a focus on secure coding practices in languages like Python, C++, Rust, Go and Kotlin/Java
  • Conduct threat modeling, vulnerability assessments and security code reviews across different platforms, ensuring security is embedded at every stage of the development lifecycle
  • Provide mentorship, guidance, and training on security best practices and secure development processes to engineering teams working in mixed cloud and operating systems environments
  • Perform vendor security reviews to assess third-party security practices and ensure compliance with standards
  • Integration of security scanning tools (SAST, DAST, etc.) into CI/CD pipelines and runtime environments to ensure continuous security monitoring and threat detection across Cloud - AWS, Azure, and on-prem systems
  • Proactively identify security risks and develop strategies for risk mitigation


Your present skillset

  • At least 7 years of experience working as a Security Architect with significant practical experience in securing software development and infrastructure at scale
  • Proven record of accomplishment in secure coding practices and development experience in development languages such as Python, C++, Rust, Go and Kotlin/Java
  • Strong technical background in software development, system architecture and security tools
  • Strong understanding of security principles, techniques and technologies related to software and product security, cloud platforms and business applications. Knowledge of low-latency financial systems would be an advantage
  • Experience working with and securing both Windows and Linux-based systems
  • Extensive experience with one or more cloud platforms such as AWS, Microsoft Azure and Alibaba Cloud used in a hybrid environment
  • In-depth knowledge of threat modeling, risk assessment and development of mitigation strategies for large-scale, complex systems in a fast-paced environment
  • Experience integrating security scanning tools into CI/CD pipelines and runtime environments
  • Experience conducting vendor security reviews and managing third-party security assessments
  • Excellent leadership, problem-solving, communication and adaptability skills, suited for a senior-level position in a fast-paced environment

Quantum-Enhanced AI in Cyber Security: Guarding the Digital Frontier

The cyber security landscape has evolved dramatically over the past decade. Long gone are the days when businesses primarily worried about simplistic phishing or basic website defacements. Today’s threats include nation-state attacks, sophisticated ransomware, AI-generated phishing campaigns, and a wide array of stealthy intrusion methods. Organisations must defend vast digital ecosystems that include cloud infrastructure, IoT devices, and critical operational technology—any of which can become high-value targets for malicious actors. Amid these escalating challenges, a new technological wave is emerging: quantum computing. Although still in its infancy, quantum computing promises capabilities that could surpass even the most advanced classical supercomputers for specific tasks. Simultaneously, in the world of Artificial Intelligence (AI)—where data volumes and model complexity are exploding—quantum’s parallelism could significantly boost analysis, training, and decision-making. What unfolds when quantum computing and AI converge in the realm of cyber security? On one hand, quantum technologies could introduce stronger encryption and faster threat detection. On the other, adversaries armed with quantum power might break today’s cryptographic protocols or develop more potent attacks at unimaginable speeds. This article explores the phenomenon of quantum-enhanced AI for cyber security: the possibilities it unlocks, the challenges it poses, and the reasons it could reshape both defensive and offensive operations in the digital world.
