  • Experience working within and improving existing backend architectures
  • Clear communication and collaboration skills across technical and non-technical teams
  • Ability to align development strategies with timelines and budgets
  • Focus on performance, maintainability, and readability
  • Comfort with writing and consuming technical documentation and architectural specs

About UserTesting

Software Development
1001-5000

UserTesting is fundamentally changing the way digital products and experiences are built and delivered by helping organizations get insights from customers–from creation through execution. Built on top of a world-class, on-demand sourcing engine, customers can receive fast, high quality, opt-in feedback from both our proprietary and partner-sourced audience networks around the world. UserTesting offers the industry's most comprehensive experience research solution. Unlike approaches that track user behavior or collect customer listening data on live experiences, then try to infer what that data means, UserTesting enables companies to get input earlier in the process, helping to reduce guesswork, and bring experience data to life with human insight.
