Why join Calendly’s Engineering team? 

As a Data Reliability Engineer at Calendly, you will have the opportunity to help scale and maintain the reliability of the data infrastructure for a product used by millions worldwide. Each member of the team has the ability to impact all aspects of the data fabric that holds Calendly together - from database design and optimization to automation of database provisioning and administration tasks.

Calendly is built using a service-oriented architecture and an automated continuous delivery system in order to efficiently deliver product solutions. A successful individual will have expertise as a database administrator, but will take this a step further and create tooling to efficiently scale Calendly’s data-tier. You will learn to be comfortable working in multiple technologies such as Google Cloud Platform, PostgreSQL, PgBouncer, Redis, and more.  

The ideal candidate has experience with automating relational database technologies in a SaaS company. Top candidates are clear communicators who are highly self-motivated and eager to collaborate, exchange knowledge, apply new skills, and pitch in with whatever the team needs to ensure data reliability.

When you join Calendly, you get the opportunity to deliver on a product used by millions, known for its best-in-class quality. Help us continue to deliver critical features to our users with excellence.

What are some of the high impact opportunities you’ll tackle? 

  • Build tooling, and provide expertise, to support our fleet of PostgreSQL databases and Redis instances
  • Ensure robust observability of the data ecosystem (using tools like Vividcortex and Datadog)
  • Build automation to help development teams own and maintain their own service-backing databases
  • Ensure system uptime and play a critical role in system recovery

This opportunity is for you if you have/are:

  • Deep experience administering production databases, especially PostgreSQL
  • Experience building and maintaining tools (preferably in Python or Go) for internal development teams
  • Keen eye for identifying and implementing database optimizations
  • Knowledge of cloud infrastructure (especially GCP or AWS), distributed systems, and reliability practices
  • Experience successfully leading the execution of strategic projects
  • Authorized to work lawfully in the United States of America as Calendly does not engage in immigration sponsorship at this time
