Senior QA Engineer

Join the CallRail Team

CallRail is looking for a Senior QA Engineer to help us deliver our next-generation call analytics platform. We’re looking for testers who enjoy the excitement of the bug chase and are passionate about finding edge cases. You’ll work closely with engineers and product managers to harden new functionality and occasionally identify flaws in existing production code.

Our product development process moves quickly, and you should be comfortable with that pace. We deploy features and updates multiple times daily, so our QA focuses on testing continually integrated changes rather than certifying a gold master release. Much of the testing for new features is manual, but that effort is supported by a maturing automation initiative.

We’re eager to expand our small QA team, so we expect you to be a confident self-starter who cares about tools and processes, but most importantly are able to be flexible in a fast paced environment. You’ll demonstrate experience testing modern web-based SaaS applications and how that experience translates to our application. You’ll be joining our Lead QA Engineer as we decide what to test and how to most effectively verify functionality. We’re lightweight on tools, documentation and process right now, and looking to improve as we scale. This QA team works closely with a mature development team and has a history of shipping successful products. We’re excited to see how you can help take us to the next level of product quality!

What We Work On

  • An analytics front-end that helps both digital and offline marketers understand which campaigns are driving calls
  • Dynamic number insertion Javascript that is installed on thousands of customer websites

  • Automated call scoring using speech recognition and machine classifiers
  • A real-time in-browser softphone interface that shows extensive details of who’s calling before your phone even starts to ring

How We Work

Our engineers use the tools listed below on a daily basis. You should enjoy working in this environment, and have the experience to prove it. As we grow our QA team we’ll be looking to add to this toolkit, and we’d love to hear your thorughts on how we should solve some of our looming challenges.

  • Ruby, Rails, AngularJS, Protractor, Ionic, Sidekiq
  • RSpec, SemaphoreCI
  • Postgres, Redis, RabbitMQ
  • Twilio, Bandwidth, Telnyx
