Job description

At CFC, technology is at the heart of everything we do. We are looking for a Principal Product Security Engineer to lead the strategy and hands-on delivery of security across cloud platforms, code and CI/CD pipelines.

This is a lead individual contributor role for an engineer who solves unique, high-impact problems, advises across disciplines and helps shape functional strategy. You will lead the build and operation of the product-security toolchain, create secure-by-default patterns and influence how security is embedded across engineering.

You will also help CFC adopt AI-assisted and agentic product engineering safely. As these practices develop, you will use proportionate guardrails, controlled experimentation and evidence-led assurance rather than assume settled industry practice.
