We're looking for a senior engineer who's spent years in the codebase—shipping features, debugging production incidents, and understanding what makes systems break—and who's now ready to focus that expertise on making our products fundamentally more secure.</p> <p>You won't just review code. You'll partner with engineering teams to shape how we build, threat model early designs, and drive security improvements that eliminate entire classes of vulnerabilities.

You've shipped real products and understand the pressures engineering teams face.</li> <li><strong>Security depth through practice:</strong> You've developed security expertise organically—as a Security Champion, through leading secure design initiatives, building security tooling, or driving security improvements on your team.
