About CallRail

CallRail is a marketing technology company. We help data-driven businesses understand which of their marketing campaigns are driving phone calls, how those calls are handled, and how those leads convert into customers.

In a nutshell, we provide smart, agile marketers the information they need to make better decisions about how to make their phone ring.

About the User Experience Team

Our User Experience team works to facilitate growth by ensuring a smooth onboarding experience for new customers. This team works to drive feature adoption, increase customer confidence, and provide in-app wizards and tutorials to get new users up to speed quickly. The team's projects are data-driven and have a heavy UX focus.

Some recent projects on the User Experience team include:

  • A guided onboarding experience to introduce new users to key components of the app and reduce the need for new users to contact our support team.
  • Utilizing an A/B testing system to measure the effectiveness of new experimental user flows.
  • Designed intuitive new UIs for creating and managing phone numbers.
  • Building and maintaining a lightning-fast, industry-leading UI.

We are looking for a full stack developer to join the team. This opening is for a senior-level candidate.

What You'll Do

  • Build great software. We take pride in the work that we do and how that work helps our customers. Our goal is to build so far superior to any alternatives that customers have no reason to consider anything else.
  • Provide technical leadership. By making solid technical decisions, sharing your knowledge and expertise, and helping your colleagues improve their designs, you’ll level up the entire team.
  • Prioritize delivering value for our customers. You'll focus on finding the smallest chunk of work that will help solve a problem. You’ll aim to deploy something useful with each iteration, if not more frequently.
  • Communicate well. You'll explain your design choices and technical approaches clearly to your 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, and collaborative. You'll help support your teammates and ensure they feel included and valued.
  • 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.


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!
