About CallRail

CallRail serves over 100,000 companies with straightforward software. Our marketing attribution platform helps businesses of all sizes, and the agencies that serve them, to maximize their marketing impact by tracing all their conversations back to the marketing efforts that drove them. 

Our team has been honored numerous times as one of Atlanta’s Best Places to Work, Inc 500’s fastest-growing companies, and G2Crowd’s top-rated inbound call tracking platform. While we’re proud of our history so far, we’re even more excited about what’s next. We’re rethinking how marketing attribution is done for hundreds of thousands of businesses, and we can’t wait for you to help us build it!



The Position

CallRail is looking for a senior software engineer with a backend focus to join our growing team. Experience with telephony and/or Twilio API is preferred.



What You'll Do

  • Deliver incredible products. We’re a product-first company, and we aren’t satisfied until we’ve built a product so clearly superior that customers have no reason to consider anything else.

  • Be a strong technical contributor. As an individual contributor, you’ll write testable, maintainable, scalable code and deploy it frequently. You’ll review the code of other developers, and be open to feedback about your own.

  • Prioritize delivery. Our team ships code multiple times daily, and you’ll help us deliver small continuous improvements with each iteration, if not more frequently.

  • Communicate well. You'll explain your work clearly to team members, and seek feedback to build a codebase we all enjoy contributing to. You’ll keep engineering leadership apprised of important developments on your team, and areas needing attention when appropriate.

  • Be a good teammate. You'll be helpful, open-minded, respectful, and collaborative. You'll support your teammates and challenge them to do their best work.

  • Learn. Regardless of your level of experience or seniority, you'll work to improve your skills and learn more about our customers and their needs.


Desired Skills & Experience

We require you be willing and able to do all of the things in the previous section. Beyond that, there are a handful of things that may make you a better fit. We'll consider candidates who don't check all of these boxes. If you've got analogous experience or a track record of being able to pick things up quickly, please tell us in your application!
