Job Title: Senior Front-End React Developer

Reports To: Development Manager, Front-End

About the Job:

atVenu is seeking a Senior Front-End React Developer to help shape the future of our platform.
In this dynamic role, you’ll collaborate closely with development teams to build new customer-driven features and modernize legacy components using current React best practices. You’ll play a key part in evolving our front-end architecture, establishing new development guidelines, and contributing to the overall user experience of our products.

We’re looking for a self-motivated, curious senior developer who thrives in a collaborative environment and takes pride in delivering thoughtful, high-quality UI. This position offers the opportunity to make a lasting impact—both in the codebase and in how we approach front-end development at atVenu.

You Will:

  • Dig into our purpose, codebase and product history to get a comprehensive understanding of our features and opportunities for improvement.
  • Collaborate with the Front-End team to design, build and maintain reusable components and development tooling using React.js and Reactive Native.
  • Rally the Product/UI/UX and Creative teams to adhere to the agreed upon standards.
  • Contribute to strategic efforts to refactor and modernize legacy code for improved performance and maintainability.
  • Develop custom components while mentoring team members across UI/UX, Product and Development Teams.
  • Own the front-end component library, from planning and development to ongoing maintenance and evolution.
  • Optimize applications for performance across a broad range of devices and unpredictable browser environments.
  • Conduct thorough code reviews to uphold quality standards, proactively identify defects, and suggest enhancements.
  • Design and execute comprehensive unit, component, and integration level tests to ensure technical requirements are met.
  • Troubleshoot and resolve complex technical issues for assigned projects.
  • Support the creation of both technical documentation and end-user product guides.

You Should Have:

  • Over 8 years of experience with React and React Native, along with deep expertise in CSS/SCSS/JSS and Redux/Redux-Toolkit.
  • Proven track record in building reusable component libraries and tooling using React and JSX.
  • The ability to identify legacy components and refactor them using modern design patterns.
  • Hands-on experience with Storybook and React Testing Library.
  • Solid understanding of SOLID and DRY principles, with practical knowledge of when and how to apply them.
  • In-depth knowledge of modern React architecture, code styling, and organizational best practices.
  • Strong problem-solving abilities; able to independently and collaboratively resolve complex technical issues with a solution focused mindset.
  • Experience leading and mentoring teams on new design patterns and best practices, both formally or informally.
  • Excellent communication skills in discussing technical concepts, with a strong passion for continuous learning.

Would Be Nice If You Had:

  • Experience with webpack and monorepo structure
  • Experience with graphQL and Ruby on Rails
Work Location:

This position allows for work-from-home within the Mountain, Pacific or Eastern Standard time-zones.
