Job: Lead Software Developer

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 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
