Lead Software Developer – Voltage SecureData Engineering

Team: Voltage SecureData Engineering

Location: Richmond Hill / Mississauga / Ottawa / Waterloo, ON, Canada (office‑based)

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 core cryptographic libraries, SDKs, and platform integrations that power the product.

Your Impact

Build the cryptographic engine behind Voltage SecureData: cross‑platform C/C++ libraries and multi‑language SDKs used 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 focuses on the portable C/C++ core, cryptographic services, and cross‑language SDK integration.

What the Role Offers

Technical Leadership

• Lead feature development from design to 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

Essential Qualifications

• 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
