About the Engagement

Akkodis is seeking the services of an experienced Software Engineer consultant to support the development and enhancement of a security-critical cryptographic platform used across multiple industries including financial services, retail, and healthcare. The engagement involves working closely with engineering, product, and customer stakeholders to design, build, and maintain a cross-platform C/C++ library delivering encryption, key management, and secure data functionality.

This is a hands-on engineering and technical leadership role requiring deep expertise in systems programming, applied cryptography, and platform-specific integrations including IBM z/OS environments.

Services to be Provided

• Provide technical leadership across design, development, and delivery of a cross-platform cryptographic engine
• Develop and maintain portable, high-performance C/C++ code across multiple operating systems and compilers
• Lead end-to-end feature development including requirement analysis, API design, implementation, and testing
• Own build, packaging, and release processes using CMake, CI/CD pipelines (GitLab CI, Jenkins), and artifact management
• Implement and review cryptographic functions including encryption algorithms, key management, TLS configuration, and secure communications
• Design and maintain multi-language SDK integrations, particularly Java and native C/C++ interoperability layers
• Drive secure coding practices including static analysis, vulnerability scanning, and dependency management within CI workflows
• Support customer-facing escalations involving cryptographic correctness, HSM integration, and platform-specific issues
• Collaborate with QA teams to define testing strategies across unit, integration, and platform qualification levels
• Engage directly with customer technical teams, including z/OS system programmers, for configuration and issue resolution

Expertise Required

• Strong experience in C/C++ development, with ability to write portable and maintainable code across platforms
• Deep understanding of operating systems and systems programming concepts (memory management, threading, dynamic linking, process isolation)
• Practical experience in applied cryptography, including symmetric/asymmetric encryption, TLS/SSL, and key management practices
• Experience designing and maintaining cross-language SDKs, particularly native-to-Java integration
• Advanced knowledge of build systems and cross-platform compilation using tools such as CMake
• Strong Java development experience with ability to work across pure Java and native-integrated environments
• Experience designing and maintaining CI/CD pipelines from code commit to release artifacts
• Proven technical leadership experience, including code reviews, mentoring, and design facilitation
• Experience working with version control systems and Agile delivery methodologies
• Strong troubleshooting and debugging skills in complex multi-platform environments.

Important

This is a business-to-business engagement. Candidates must represent an incorporated entity, hold a valid business number, maintain appropriate insurance, and invoice for services rendered.

Nice to Have

• Experience with C#/.NET and native interoperability, including .NET Standard and NuGet packaging
• Knowledge of HSM integrations and standards such as PKCS#11 (e.g., Thales, nCipher, Atalla)
• Familiarity with post-quantum cryptography standards and emerging algorithms
• Experience with payments industry standards (ISO 8583, EMV, PCI-DSS)
• IBM z/OS experience including JCL, HLASM, xLC/C++, SMP/E, RACF/ACF2, and z/Architecture
• Experience with HPE NonStop systems and low-level system programming concepts
• Strong experience with CI/CD, containerization, and modern DevOps practices
