Sr Staff Engineer - Core Infrastructure

About The Role

We are seeking a Senior Staff Engineer (L6) to lead the technical strategy and evolution of Uber's Core Infrastructure Platform. As a Senior Staff Engineer, you are the principal architect of an ecosystem that handles 1M+ concurrent trips and massive-scale ML workloads. You will own the technical roadmap for our Compute, Foundations, and Software Networking stack, driving the shift from "Service Provider" to "Strategic Partner."

We aren't looking for a maintainer; we're looking for a visionary who can drive Platform Engineering 2.0. You will solve the "hard problems" of extreme scale-driving fleet utilization from 26% to 40%+, scaling GPU pools for Generative AI, and ensuring "Security by Design" across a global multi-cloud footprint.

• Architect Strategic Efficiency:
  Own the technical vision to drive fleet-wide CPU utilization and unit-cost optimization through ARM adoption (targeting XM+ cores) and silicon diversity.
• Scale AI & ML Infrastructure:
  Define the architecture for shared GPU pools and high-performance clusters to support 300x larger ranking models and Autonomous Vehicle data ingestion.
• Modernize the Data Plane:
  Drive the convergence of Uber's networking stack toward industry standards (Kubernetes, Envoy, CNI) while enhancing "Sky Edge" for active-active multi-cloud resilience.
• Enforce Foundations & Reliability:
  Lead the "100% Done-Done" initiative, ensuring every service follows standardized safe-deployment (Starship) and reaches 100% zero-trust authorization.
• Agentic Augmentation:
  Integrate AI-driven "Minions" and AIOps into the infrastructure to automate 80% of alerts and unlock thousands of years of developer productivity.
• Cross-Org Influence:
  Partner with Delivery, Rides, and AV teams to ensure the infrastructure isn't just a container, but a competitive advantage that accelerates their time-to-market.
• Mentor Staff+ Engineers:
  Act as a force multiplier by coaching the next generation of technical leaders and influencing company-wide engineering standards.

• 12+ years of software engineering experience , with a focus on massive-scale distributed systems or infrastructure.
• Proven Track Record at Scale:
  Experience managing infrastructure that supports millions of concurrent users or petabyte-scale data processing.
• Deep Systems Expertise:
  Mastery of Kubernetes internals, container runtimes, and the Linux kernel, with the ability to debug "impossible" performance bottlenecks.
• Cloud-Native Fluency:
  Deep experience with cloud-native networking (Envoy, CNI, Service Mesh) and multi-cloud (AWS/GCP) architecture.
• Coding Proficiency:
  Expert-level proficiency in Go, Java, or C++ .
• Leadership:
  Demonstrated ability to lead 40+ person technical initiatives and influence VPs and GMs on infrastructure investment.

• Hardware/Silicon Strategy:
  Experience optimizing software for ARM architecture or specialized AI hardware (GPUs/TPUs).
• Open Source Leadership:
  Significant contributions to Kubernetes, CNCF projects, or other major infrastructure open-source communities.
• AIOps & Automation:
  Experience building self-healing infrastructure or using LLMs/ML to automate infrastructure operations and incident response.
• Zero-Trust Security:
  Hands-on experience implementing S2S/P2S security models and ransomware-resilient infrastructure.
• Cost-Aware Engineering: A proven history of driving XXM+ in annual P&L savings through architectural efficiency and resource scheduling.
• Linux & Kernel Knowledge:
  Understanding of operating systems, Linux kernel performance tuning, or eBPF.

This isn't the kind of place where you follow a playbook - it's where you help write one. If you're driven by impact, energized by challenge, and ready to shape how the world moves - we'd love to hear from you.
