Your expertise will be crucial in conducting thorough security assessments and investigations, ensuring the integrity and safety of our platform. You will collaborate closely with our talented development teams, embedding security best practices throughout the entire software development lifecycle (SDLC) and championing a security-first mindset.
  • • A core responsibility will be to own and manage critical security infrastructure and services, with a particular emphasis on Key Management Services (KMS) for our wallet infrastructure. This involves ensuring the robust security and availability of cryptographic keys, which are fundamental to the trust and security of our users' crypto assets.
  • • You will conduct regular, in-depth security assessments of new projects, infrastructure deployments, and existing codebases. This proactive approach will involve identifying and mitigating security risks before they can be exploited, utilizing a combination of manual testing, advanced automated tools, sophisticated threat modeling, and up-to-the-minute threat intelligence.
  • • Staying ahead of the curve is paramount. You will be expected to continuously keep abreast of the latest offensive security techniques, emerging application security threats, and evolving best practices, especially within the rapidly advancing blockchain and cryptocurrency space. Your insights will be vital in recommending and implementing improvements to our overall security posture.

These reports will be presented to both management and technical teams, providing clear insights into potential risks and actionable recommendations to prevent real-world attacks and protect our user base.
  • • You will actively work with development teams to foster the adoption of secure coding practices. This includes providing guidance on implementing cryptographic functions securely and ensuring the overall integrity of our software from a security perspective.
  • • Collaboration is key to our success. You will work closely with various teams, including development, platform engineering, and operations, to ensure that security considerations are seamlessly integrated into all aspects of the organization's activities and workflows.
  • • You will be a crucial participant in our incident response and incident management processes. This involves contributing to the swift and effective resolution of security incidents, minimizing impact, and conducting thorough post-incident analyses to prevent recurrence.
  • • Furthermore, you will have the opportunity to lead significant, cross-team security projects, driving initiatives that enhance our security capabilities and protect our rapidly growing user community.
