Senior Systems Engineer, Edge Services

The Edge Services team builds and runs Quantcast's globally distributed data infrastructure that handles peak loads of 3 million requests per second, each served in milliseconds.

We are looking for experienced system engineers who understand that simplicity and reliability are aspects of a system to be carefully calculated with every decision made. We’re a collaborative team that enjoys working together to improve our systems and to make them more reliable.

Here's what you might do over the course of a typical week on our team:

  • Through analyzing and monitoring an Edge service you find a way to make the system more stable under network partition
  • You write the necessary code alongside unit tests, and then verify your assumptions while incrementally deploying your change
  • You clarify the way our physical machines receive and bootstrap their configuration, test it through unit tests and canaries, and then incrementally deploy it to our fleet of machines
  • You collaborate with peers to write or review technical design proposals, and provide feedback for challenging technical questions
  • You contribute to internal tools that help us improve our development process and scale our systems.

Here are things we consider critical to being a Senior Systems Engineer:

  • You think about systems — their edge cases, failure modes, and life cycles.
  • When things break — and they will — you are eager and able to help fix them.
  • You have been building and operating complex systems for 5+ years and can demonstrate things you’ve accomplished
  • You have deep knowledge of Unix systems — how they fail, and how we can run them well
  • You know how the web works. You know HTTP and TCP/IP and what a good API looks like
  • You are a strong communicator. Explaining complex technical concepts to designers, support, and other engineers is no problem for you.
  • You have a B.S. or M.S. in Computer Science or a related field, or equivalent work experience.

Bonus points:

  • You have prior experience with or knowledge of large scale, high volume systems
  • You have detailed experience with system configuration-management systems like Puppet, Chef, or Salt
  • You have used AWS or other cloud providers to operate large services

Quantcast is a fast-growing, late-stage, pre-IPO startup headquartered in San Francisco with offices around the world. We are committed to creating an inclusive and diverse environment where everyone can confidently be their authentic self.
