Senior Software Engineer (Product Security)

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Software Engineer (Product Security) based in Canada.

This role combines senior-level software engineering with a strong product security focus in a cloud-native infrastructure environment. You will design, build, and maintain production features while helping embed security directly into the product and engineering lifecycle.

Your work will span vulnerability response, threat modeling, security-sensitive design reviews, and technical decision-making across the platform. You will work deeply within the codebase and architecture rather than focusing primarily on security tooling or compliance operations.

The role offers significant technical ownership and the opportunity to influence secure engineering practices across a distributed, remote-first team.
