Staff Software Engineer (L4)

Twilio provides the communications APIs that a large share of apps use to send messages and make calls, and the company is remote first, so this role is genuinely open anywhere in India. The work is anti-fraud and anti-abuse: scoping, designing and deploying machine learning systems that keep traffic across Twilio's platforms legal and wanted, built as cloud distributed systems handling several million transactions a day. The posting asks for 7+ years designing, building and operating high scale, mission critical production systems. This is a staff level opening rather than a step up from mid level, but the remote first policy makes it one of the more accessible senior roles for anyone based outside the main tech hubs.
