About the role

We're looking for mid-level full stack engineer to join a focused application security initiative.

This is hands-on engineering across the full stack. In a given week you might upgrade a .NET authentication library and chase down the breaking changes, remediate an XSS vulnerability in an Angular component, parameterize a SQL query to close an injection risk, and harden a Dockerfile to stop running as root.

What you'll do

• Remediate security findings across the stack — dependency upgrades (NuGet, npm), code-level fixes (authorization, XSS, path traversal, SQL injection, weak cryptography), credential rotation, and container/Kubernetes hardening
• Write tests for every fix — unit tests proving the vulnerability is closed, plus functional verification that the feature still works
• Own upgrades end to end — when a major version bump breaks the build or changes behavior, you diagnose it and see it through
• Document what you learn — because findings repeat, your written analysis of one upgrade saves your teammates from repeating the work
• Collaborate across teams — many of these repositories are owned by other teams; you'll need their context and their review
• Coordinate credential rotations — some fixes require finding every consumer of a secret and sequencing a safe rollout with DevOps
• Raise judgment calls — when a suggested fix is wrong for our architecture, or a finding is a false positive, say so with reasoning
• Help make it stick — set up automation so routine dependency updates never pile into a backlog again
