About Voltage SecureData

Voltage SecureData is OpenText’s data-centric encryption platform, protecting sensitive information across cloud, on-premises, and mainframe environments. The team develops the core cryptographic libraries, SDKs, and platform integrations that power the product.

Your Impact:
Join the team that builds the cryptographic engine behind Voltage SecureData: cross-platform C/C++ libraries and multi-language SDKs used by banks, retailers, and healthcare organizations worldwide.
The platform supports Linux, Windows, macOS, AIX, Solaris, IBM z/OS, and HPE NonStop, with SDKs for Java and C#/.NET. Most engineering work centers on the portable C/C++ core, cryptographic services, and cross-language SDK integration.

This is a hands-on engineering leadership role. You will write and debug production code, lead technical design discussions, mentor engineers, and help resolve complex customer and platform issues.

What the role offers:
Technical leadership

Lead feature development from design through implementation and release
Set standards for code quality, testing, and reviews
Drive cross-platform build and CI/CD strategy using CMake, GitLab CI, and Jenkins
Maintain API and ABI stability across platforms and releases
Mentor engineers and support architectural decision-making
Partner with QA on unit, integration, and platform qualification testing
Act as an escalation point for cryptographic, HSM, PKCS#11, and platform-related defects

Hands-on engineering

Develop and review cryptographic functionality, including:
symmetric and asymmetric encryption
key management and wrapping
TLS configuration and certificate handling
message authentication and format-preserving encryption
Own Java and C# SDK layers, including native interoperability with the core C library
Improve platform security posture, including FIPS 140 and post-quantum readiness

Platform-specific work (desirable)

Support IBM z/OS integrations involving xLC/C++, JCL, SMP/E, RACF/ACF2, and COBOL/native interfaces
Maintain HPE NonStop platform support and customer fixes as required

What you need to succeed:
Essential

Expert-level C/C++, C#, and Java development
Strong systems programming background across Linux, Windows, or UNIX-like platforms
Experience building portable, maintainable cross-platform software
Practical applied cryptography experience:
TLS/SSL
public-key cryptography
symmetric encryption
message authentication
key management
Experience with native interop and cross-language SDK design
Strong build engineering skills with CMake and CI/CD pipelines
Technical leadership experience in code reviews, architecture, and mentoring

Strongly preferred

PKCS#11 and HSM integration experience (nCipher, Atalla, Thales Luna)
JVM and managed-runtime debugging experience
Knowledge of post-quantum cryptography
Payments/security standards such as EMV, PCI-DSS, or ISO 8583
Experience using AI-assisted development tools effectively in production environments

Nice to have

IBM z/OS development experience
HPE NonStop experience
Familiarity with non-POSIX and enterprise systems environments

What we offer

Ownership of security-critical systems used by major enterprises
Rare exposure to platforms such as IBM z/OS and HPE NonStop
Direct involvement in cryptographic and platform-level engineering challenges
A senior, engineering-driven team focused on technical quality and real-world problem solving
