Who You Are

As a Senior Front End Software Engineer at TrainingPeaks, your primary role is to build software that helps our athletes and coaches achieve their goals.

  • Work with other engineers to improve existing architecture and define new architecture patterns, and to research and implement tools and processes that enhance quality and increase productivity
  • Plan and implement refactoring projects to reduce technical debt and improve system architecture
  • Mentor junior engineers
  • Perform other duties as assigned


To be successful in this position, you possess:

  • Several years experience working on challenging problems in complex JavaScript applications
  • Deep expertise in React and Flux or Redux, as well as other front end frameworks and state management libraries
  • Familiarity with a variety of front end architectural patterns, frameworks, and libraries
  • Familiarity with current and upcoming JavaScript features and best practices
  • Familiarity with current and upcoming CSS and HTML features and best practices
  • Deep understanding of web browser and js framework performance best practices
  • Experience with unit testing, integration testing, and test driven development
  • Experience working with RESTful APIs
  • Experience with mentoring junior developers on writing code that is clean, maintainable, and testable
  • Strong written and verbal communication skills
  • Demonstrated commitment to continuous improvement of yourself and your team

Additional desired qualifications:

  • Experience with cross functional teams, using agile, kanban, or other modern development methodologies
  • Familiarity with continuous delivery and build automation principles
  • Experience with server side API programming
  • Experience with .NET framework and C#
  • Experience writing and tuning database queries for SQL databases
  • Understanding of principles of system architectures
  • Understanding of the needs of endurance athletes and coaches
