The Backend team is responsible for developing, scaling, and maintaining both Dashboard, our web application, as well as the lower-layer services and infrastructure that support all of our Meraki devices worldwide. Every day, our servers handle tens of millions of users that access our Dashboard app, hundreds of millions of visitors clicking through a Meraki splash captive portal page, and tens of billions of requests from the millions of devices worldwide that check in more than once a minute, 24/7/365.


While our team largely focuses on backend services and infrastructure, we also work on customer-facing features, including some of Meraki’s most data-heavy features. Because of the broad nature of our responsibilities, the backend team works across all levels of the stack—from firmware all the way up to UI—on projects that span numerous domains: networking, databases, web app development, systems, and even approximation algorithms to help with data processing. Finally, along with the Backend Infrastructure and Security teams, we are one of the first teams to respond when critical backend issues arise.


Key technologies:

  • Languages: Scala, Ruby on Rails, C/C++, Javascript, Click (packet processing framework)

  • Databases: PostgreSQL and LittleTable, our custom time-series relational database that provides high-throughput access to 100 of TB’s of data

  • MTunnel, the custom VPN-like infrastructure that provides secure connectivity between hundreds of globally-distributed servers and millions of Meraki devices worldwide

  • Custom frameworks for collecting data from and pushing data to Meraki devices, as well as frameworks for processing and aggregating all the data we collect from our devices

  • Approximation algorithms that trade off some accuracy for much better performance

  • Gossip and dissemination protocols for propagating data across our backend servers

  • Other core backend features: proxies, authentication, dynamic DNS services, and more!


You are an ideal candidate if you have:

  • 3+ years of relevant work experience in software development, particularly in systems, networking, distributed systems, databases, or data processing frameworks

  • Strong familiarity in one of the following languages: Scala, Ruby, Java, Python, C/C++

  • A disciplined, organized approach to development, testing, and quality

  • Excellent communication and presentation skills

  • Experience in analyzing, scaling, and debugging large systems processing lots of data

  • Passion for the science in computer science


Bonus points for:

  • A BS/MS/Ph.D in Computer Science, Computer Engineering, or a STEM field

  • Substantial personal projects or contributions to open-source projects

  • Experience with web development and Javascript frameworks (e.g., ReactJS)

  • Experience with dev-ops/infrastructure tasks
