Senior Systems Engineer, Edge Services

Quantcast seeks distributed systems enthusiasts, networking diehards, and performance aficionados to join our Edge Services team!

This tight-knit group of cavaliers is tasked with conquering the vast Internet badlands as they develop and maintain Quantcast's high-performance network edge--a world-class, globally-distributed data infrastructure that handles peak loads of 2 million requests per second -- each served in milliseconds.

Systems engineers on the Edge Services team are serious about building & running high-throughput, low-latency systems. Whether it's replacing your predecessor with a shell script or debugging kernel locks, you will bring out every drop of performance and reliability to let everyone sleep well at night.

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've 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've 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.
