Senior Software Engineer, Software Networking (SRE) - Seattle

Uber Overview

Uber has become an integral part of many people’s lives. It is critical that the systems that power the platform are always available to everyone in the world. Uber continues to expand into new cities and its growth and popularity presents interesting challenges for matching developer agility with the scale and complexity of its infrastructure. We are looking for senior engineers that are able to apply sound engineering principles and build robust distributed systems to solve infrastructure challenges, while enhancing developer productivity and maintaining operational simplicity.

Our networking infrastructure spans physical data centers and cloud providers. You will be part of the software networking site reliability engineering team with a healthy mix of software engineering and systems engineering background, executing in a fast paced environment. If you love working on software products that touch the physical world and want some serious experience under exponential growth conditions, this is the role for you.

Are you among the rare breed of software engineers with strong systems engineering and operational background? Do you have a passion for designing and maintaining highly reliable systems? As a Senior Software Engineer in the software networking infrastructure team, you’ll be responsible for one of the following areas: load balancing, service discovery, traffic routing and health management systems. You will be building infrastructure management and automation tools that will enable you to provide software networking infrastructure components as a service for other engineering teams. Load balancing millions of requests globally, discovery and routing requests to thousands of micro services end points and building fault tolerant solutions are some of the challenges you will be presented with.
