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

One last thing:
OpenText is more than just a corporation, it's a global community where trust is foundational, the bar is raised, and outcomes are owned. 
Join us on our mission to drive positive change through privacy, technology, and collaboration. At OpenText, we don't just have a culture; we have character. Choose us because you want to be part of a company that embraces innovation and empowers its employees to make a difference.
