About the Role

As a Senior Staff Engineer at Uber, you will serve at the highest level of technical leadership, defining strategic direction, system architecture, and technical vision across global engineering platform teams and core business units. Senior Staff Engineers at Uber exert broad influence on critical technology and business choices across various organizations. In this role, you will act as a pragmatic, passionate technologist capable of designing, building, and deploying resilient, large-scale systems.

Beyond executing on uniquely complex initiatives, you will act as an accessible thought leader, collaborative partner, and humble mentor, guiding and developing talented engineering teams.

The Communications Platform at Uber powers all real-time and asynchronous customer interactions worldwide. Operating as the underlying engine for global engagement, the platform provides high-throughput, fault-tolerant, low-latency & cost efficient smart routing infrastructure across voice, SMS, chat, push notifications, email and other 3rd party messaging channels(whatsapp etc) for Riders, Drivers, Couriers, Merchants, and Enterprise partners.

Central to our strategy is our multimodal Conversational AI platform, which unifies voice and chat channels, real-time media processing, and LLM-driven orchestration. This platform powers context-aware AI agents and proactive intervention frameworks that optimizes Uber's global marketplace efficiency, safety, and operational reliability.

In this role, you will establish platform reliability standards and drive AI driven innovation helping the team’s mission to deliver magical communication experience to hundreds of millions of riders, drivers, couriers, and enterprise partners globally. You will act as a mentor to senior engineering talent, and be the principal architect behind high-stakes, large-scale distributed systems. You will define the multi-year architectural roadmap for core backend microservices, real-time streaming engines, vendor integrations, and interactive, multimodal conversational UI frameworks across web and mobile.

By integrating state-of-the-art conversational AI models and real-time speech orchestration layers into core platform infrastructure, you will ensure sub-second latencies, high fault tolerance, and zero-downtime availability. Through intelligent automation and real-time observability, you will set the benchmark for AI-driven communication platforms at Uber scale.

This is a high-visibility, transformative role interfacing directly with Uber's core marketplace teams, safety, fraud, customer care, and AI infrastructure organizations. If you are a battle-tested technical leader, strategic architect, and collaborative executor, we invite you to join us in defining the future of AI driven real-time communication platforms.
