Senior Software Engineer, Application Security

Discord is where communities and friend groups spend time together, on desktop, mobile, and now more and more inside games and third-party apps built on our platform. That surface area, plus a huge, engaged, occasionally adversarial user base, makes application security a genuinely hard and interesting problem here. We are hiring a Senior Software Engineer to join the Application Security team. This is hands-on product engineering: building security features that protect user accounts, strengthening authentication and session security, and improving security-critical services. You will work directly with product teams to ship user-facing account security tools and address emerging threats. Stack: Python primarily, some TypeScript/React, some Rust, occasional JavaScript. Runs on GCP. Looking for: hands-on AppSec experience (not just compliance-flavored security), comfort reading and writing code across languages, experience shipping production software, and sound judgment on prioritizing real risk over checklist security. Experience with authentication, passkeys, MFA, or session management is especially relevant. Location: Remote from the US West Coast. If you are in the Bay Area, our SF office is an option. Relocation to the Bay Area is not required. Interview process: recruiter call, coding round, HM interview, virtual onsite, decision. Apply: https://discord.com/jobs/8656854002
