Staff Software Engineer, Inventory

Quantcast is hiring a Staff Software Engineer to join the Inventory team in our Singapore office.

We have created one of the world's largest, living data-sets and we use it to bring unparalleled relevance to online advertising. By utilizing technology and big data to understand digital audiences, Quantcast solves the biggest challenges in marketing. 

As a Staff Software Engineer, you will be designing, building and running high-throughput, low-latency systems. Whether it's for a code one-liner or an entirely new design, these developers tirelessly tweak, optimize, re-architect, and refactor until the last drop of performance has been juiced from the system. While many companies have globally distributed infrastructures with high traffic demands, Quantcast may be the only one of these in which you will be expected to have your hands on the system of a very large scale, pushing mission-critical production code within a matter of weeks and leading the effort soon thereafter.


  • Take full ownership of a service, and its production operation in a highly complex and globally distributed system scalable to handle tens of billions of real-time transactions per day
  • Be able to understand high level and complex business requirements and turn these into effective designs and implementation
  • Be part of the leadership team, forming strategy and future direction of the real-time bidding infrastructure
  • Be a thought leader in the area of improvement of development and production operation processes
  • Innovate with new designs and optimizations to enhance the performance of existing infrastructure


  • BS or MS in Computer Science or related field
  • Passionate about engineering excellence, good practices and continuous improvement thereof
  • Expert in Java or C++ and at least one of the major scripting languages (e.g. Ruby, Python, shell)
  • Expert understanding of networking protocols (HTTP, TCP/UDP/IP, etc.)
  • Proficiency and high level of insight into Linux OS and running software systems on Linux

Quantcast is a 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.
