Software Engineer - Metrics (London)

Yelp, London, UK

Connecting people with great local businesses

Yelp’s Infrastructure teams design, implement, and maintain scalable software architectures that are at the heart of our technology. We do everything from building performance monitoring tools, to designing APIs and developing libraries, to creating speedy and reliable infrastructure that’s easy to use for our relevance/machine learning developers.

Do you feel the need to quantify everything around you? Do you love diving deep into data in order to analyse trends or discover hidden patterns? Do you always know what you need to know, when you need to know it due to your meticulous alerting? So do we! The Metrics team helps Yelp organize and understand its operational and application data by building tools to collect, monitor, and alert on the right things at the right times. We handle everything from fault-tolerant streaming and aggregation of real-time systems data across Yelp’s entire server fleet to designing new metrics collection and alerting strategies for other development teams.

What You Will Do:

  • Design, build and deploy software systems that run 24/7 at great and increasing scale.
  • Help your fellow engineers design, build, and analyse metrics and monitoring systems for applications they’re building.
  • Tune metrics pipelines to handle tremendous volumes of data with high reliability.
  • Develop custom tools and automate processes to find answers to challenging questions and reveal the unknown.
  • Write code, document, participate in code reviews, and mentor other engineers.
  • Support the systems you’ve built in a follow-the-sun on call rotation.

What We Are Looking For:

  • Strong knowledge of distributed systems and application design, with an understanding of operational and reliability trade-offs.
  • Solid foundation in data structures, algorithms, and complexity analysis.
  • A hunger for tracking down root causes -- no matter how deep it takes you -- and fixing them in systematic ways.
  • Strong understanding of operating systems, file systems, networking, and web technology.
  • Experience with cloud computing services like AWS.
  • Experience with configuration management tools (Puppet, Chef, Ansible, Salt, CFEngine), monitoring (Nagios, Sensu, Monit), and metrics (Graphite, statsd, fullerite).
  • Fluency in Python, C, C++, Java, or a similar language.
  • Ability to work well with and influence many personality types at all levels of the organization.


  • Experience building and supporting large-scale distributed systems.
  • Experience working at a large-scale consumer web site.
  • Experience using and maintaining Splunk.
