This is a 3 month fixed term salaried contract, located in Ontario Canada. Preferably in Toronto.

About You:

We're looking for a Senior Linux C/C++ Engineer to join a focused remediation effort on a long-running production platform serving a global financial news and data client. This is a temporary senior engagement with real ownership: you'll be working directly inside a complex, unfamiliar legacy codebase, identifying and resolving security vulnerabilities, upgrading components, and supporting a broader re-platforming effort.

A key portion of this role will be working GenAI coding tools to accelerate these upgrades.
    
The right person for this role isn't fazed by legacy code they didn't write. They're energized by the challenge of understanding it, diagnosing what's wrong, and fixing it properly. Persistence, methodical debugging, and the ability to navigate ambiguity are what will make you successful here.

What You’ll Do:

• Analyze existing Linux-based C/C++ services to identify security vulnerabilities and stability risks
• Remediate vulnerabilities and apply secure coding practices across critical production services
• Upgrade legacy components and dependencies, ensuring stability is maintained throughout
• Support re-platforming activities as NewsEdge functionality is migrated to compliant, modern infrastructure
• Work closely with application and platform teams to manage dependencies and coordinate changes safely
• Contribute to testing and validation to ensure remediation work doesn't introduce regressions

What You Bring:

• 5+ years of hands-on C/C++ development experience in Linux environments — this is the core of the role
• Proven ability to work in unfamiliar, underdocumented legacy codebases — reading and reasoning about code you didn't write
• Experience with security vulnerability remediation: identifying, triaging, and resolving issues in production systems
• Comfortable with dependency and component upgrades in complex, tightly coupled systems
• Proven ability to work effectively in GenAI coding tools. This client uses Claude but any tool is fine.
• Strong debugging skills — methodical, patient, and effective under pressure
• Experience with stabilisation and re-platforming efforts in live production environments
• Secure coding practices and awareness of common vulnerability classes (e.g. memory safety, injection, buffer overflows)
• Strong communicator — able to document findings, explain risk clearly, and flag blockers early

The anticipated hourly range for this position is $58-70 hourly. Rate is based on a range of factors that include relevant experience, expertise, and organizational impact. This is based on a 40-hour workweek and leveling. Keep in mind, we're flexible.
