Sr Software - Core Infrastructure

About the Role

Senior Engineers at Uber have a deep impact across a wide variety of business and technology decisions. As a member of the Core Infrastructure team, you will build the foundational platform—spanning Compute, Networking, and Foundations—that powers every Uber trip, delivery, and freight shipment globally.

We are looking for a pragmatic, high-execution Senior Engineer to help us build highly available, mission-critical systems that are "Secure by Design" and "Cloud-Native by Default." Whether it’s driving fleet-wide CPU efficiency, modernizing our global service mesh, or automating safe deployments, your work will directly impact Uber’s bottom line and developer velocity.

What the Candidate Will Do

• Design & Scale Core Services: Build and maintain the next generation of infrastructure services (Compute, Networking, or Tooling) capable of supporting XM+ sustained concurrent trips.
• Drive Efficiency & Optimization: Contribute to large-scale initiatives to improve resource utilization (targeting 40%+ fleet utilization) and optimize unit costs across multi-cloud and on-prem environments.
• Enable Multi-Cloud Resilience: Develop features that support Uber’s "Thrive in Cloud" strategy, ensuring seamless failover and active-active reliability across multiple cloud providers.
• Automate the Lifecycle: Build "AIOps" and agentic automation tools to reduce manual operational load, aiming to automate incident response and alert triaging.
• Collaborate Across Infra: Work cross-functionally with Storage, Data, and Product teams to ensure infrastructure is a seamless enabler for business growth (e.g., scaling for AI/ML workloads).
• Mentor & Execute: Lead by example with high-quality code and rigorous testing, while providing technical mentorship to help mid-level engineers grow.

Basic Qualifications

• 5+ years of software engineering experience, with a focus on backend services, infrastructure, or distributed systems.
• Systems Languages: Strong proficiency in Go, Java, or C++.
• Reliability at Scale: Proven track record of building, deploying, and operating production services that handle high throughput and require 99.99% availability.
• Problem Solving: Ability to debug complex issues across a distributed stack, from application code down to the networking or container layer.
• Communication: Strong technical writing skills for RFCs and design documents, with the ability to articulate technical trade-offs to stakeholders.

Preferred Qualifications

• Cloud-Native Expertise: Experience with the modern CNCF ecosystem, including Kubernetes, Envoy, or Prometheus.
• Efficiency Mindset: Experience in performance tuning, capacity planning, or cost-optimization of large-scale clusters.
• Infrastructure as Code: Familiarity with modern deployment patterns (e.g., Starship, GitOps) and automating infrastructure lifecycle management.
• Hybrid/Multi-Cloud: Experience architecting services that run across on-prem data centers and public clouds (AWS/GCP).
• Security & Compliance: Knowledge of Zero-Trust architecture, mTLS, and building ransomware-resilient systems.
• Leadership: Experience leading technical projects from conception to launch, influencing team roadmaps and technical standards.
