What are the responsibilities and job description for the Security Engineer (Blockchain & Cryptography) position at IntePros?
Security Engineer (Blockchain & Cryptography)
We are seeking a highly skilled Security Engineer to help build secure, resilient software that supports next-generation digital asset and cryptographic platforms. This is a hands-on backend engineering role focused on implementing advanced cryptographic concepts into production-ready software-not a traditional cybersecurity or security operations position. You will work alongside cryptographers and software engineers to develop secure transaction processing, digital asset custody capabilities, and trusted execution environments.
This is an excellent opportunity for engineers who enjoy solving complex security challenges involving blockchain technologies, secure systems design, and modern cryptographic frameworks.
Responsibilities
The ideal candidate is first and foremost a strong software engineer with experience building secure backend systems. While experience in blockchain or digital assets is highly desirable, we are equally interested in engineers who have deep expertise in secure software development, cryptography, and distributed systems and are excited to work on cutting-edge technologies.
This role offers the opportunity to contribute to research, prototyping, and production development of highly secure systems that support the future of digital assets and cryptographic infrastructure.
