Summary of Role V-Key is one of the world’s leading deep-tech companies in mobile cyber-security. Our patented technology V-OS has been deployed by top banks, mobile payment providers, and governments to secure software solutions and protect more than 500 million users globally. We are rapidly expanding into new markets and new customer segments. Apart from securing digital transactions for everyone, we are also enabling new generation technology by providing the cyber-security infrastructure for banking, government and smart homes, among many others. At V-Key, we are building towards a future where technology users can enjoy unprecedented security and convenience. We are looking for a highly motivated Cryptography Engineer to design, develop, maintain and integrate secure cryptographic solutions across our platform. You will work closely with architecture team and product teams to build scalable, secure systems leveraging Hardware Security Modules (HSMs), key management infrastructure, and modern cryptographic practices. This role is ideal for engineers passionate about applied cryptography, secure system design, and solving real-world security challenges in large-scale environments. Roles and Responsibilities Design, implement, and maintain cryptographic solutions, including integration and customization of Hardware Security Modules (HSMs) to provide secure cryptographic services. Design, implement, and maintain secure processes for generation and management of cryptographic assets (e.g., cryptographic keys) within a controlled environment. Collaborate with Product Owners and security experts to implement secure cryptographic workflows and tooling Provide cryptography guidance and consultancy to engineering teams, promoting the correct use of cryptographic primitives and best practices. Support internal and external stakeholders by troubleshooting cryptographic implementations, managing technical issues, and clearly communicating complex concepts.
