Lead Software Engineer (St. Catharines)

Job Title: Lead Software Engineer – Core Cryptography (C/C++ And z/OS)

Location: Remote within Canada

Contract: 6 months (Possible extension)

About the Role

We are looking for a Lead Software Engineer to join the team owning the cryptographic engine at the core of Voltage SecureData. This is an engineering-first leadership role where you will write production code, lead design decisions, and work hands-on with complex, security‑critical systems used by major financial institutions.

The platform is a cross‑platform C/C++ cryptographic library shipping across Linux, Windows, macOS, AIX, Solaris, IBM z/OS, and HPE NonStop, with SDKs in Java and C#/.NET.

What You’ll Do

Technical Leadership

• Define coding standards, testing strategy, and code review culture

• Lead feature design end‑to‑end (requirements → API → implementation → qualification)

• Own cross‑platform build and release tooling (CMake, GitLab CI, Jenkins)

• Drive security scanning, static analysis, and vulnerability management in CI/CD

• Make architectural decisions to ensure ABI/API stability across platforms

• Mentor engineers and translate product requirements into execution plans

• Act as escalation point for customer‑facing cryptographic and HSM issues

• Partner with QA on unit, integration, and platform qualification testing

Hands‑On Engineering

• Implement and review cryptographic functionality in C/C++

• Own and evolve the Java SDK, including native C interop layers

• Drive TLS hygiene initiatives (cipher suites, cert management, FIPS 140)

• Prepare the platform for post‑quantum cryptography readiness

IBM z/OS Focus

• Build or own deep expertise in the IBM z/OS port

• Work with xLC/C++, HLASM, JCL, SMP/E, and COBOL callable boundaries

• Collaborate directly with customer z/OS system programmers

• Support RACF/ACF2, SAF integration, and TLS configuration

What We’re Looking For

Essential Skills

• Expert C/C++: portable, maintainable, cross‑platform systems code

• Systems Programming: deep OS knowledge (Linux, Windows, AIX, etc.)

• Applied Cryptography: TLS, key management, symmetric & asymmetric crypto

• Native Interop: production experience across language boundaries

• Build Engineering: multi‑platform CMake and shared‑library versioning

• Java: solid JVM and native‑integrated Java experience

• CI/CD Ownership: from commit to signed production artifacts

• Technical Leadership: proven mentorship and design leadership

Strongly Preferred

• C# / .NET interop and NuGet packaging

• HSM & PKCS#11 integration (Thales, nCipher, Atalla)

• Post‑quantum crypto (ML‑KEM, ML‑DSA, SLH‑DSA)

• Payments standards (PCI‑DSS P2PE, EMV, ISO 8583)

• IBM z/OS or HPE NonStop experience

What We Offer

• Ownership of a security‑critical platform used by global financial institutions

• Rare exposure to IBM z/OS and HPE NonStop environments

• Direct customer engagement on complex cryptographic problems

• A senior, technically driven team where expertise leads decisions
