Who We Are:

Twitter is what’s happening and what people are talking about right now. For us, life’s not about a job, it’s about purpose. We believe real change starts with conversation. Here, your voice matters. Come as you are and together we’ll do what is right (not what’s easy) to serve the public conversation. 

The Product Security and Architecture team works across Twitter to build security into everything that we do. You’ll work directly with internal and external stakeholders to define security testing requirements, lead testing engagements, and reduce overall risk to deployed applications and infrastructure by proactively identifying potential vulnerabilities.
