  • Developing performant front-end components and solid front-end architectures that easily integrate with other systems and technologies.
  • Collaborating with a cross-functional and global team of product owners, back-end developers, enterprise architects, designers, and QA to understand detailed requirements and deliver robust cloud-based solutions to drive business growth and profitability.
  • Utilizing programming languages and frameworks like React, Typescript, JavaScript, HTML, CSS, and LESS/SASS.
  • Experimenting with and learning new technologies and mentoring other members of the engineering team.
Requirements
  • 5+ years of experience with building modern web applications with JavaScript/Typescript (React, Vue.js, Angular

    JS) and semantic HTML5/CSS3 including:
  • Ability to work with remote, RESTful APIs, and third-party web services
  • Loading data asynchronously
  • Understanding state management
  • Using JavaScript templates and dynamic views
  • Using pre-processors
  • Experience with cloud services
  • Experience working in an agile development cycle
  • Proficient in Git version control, responsive design methodologies, and establishing engineering best practices
  • Well-versed in test-driven development principles and able to write clear, meaningful tests for all functionalities.
  • Solution-oriented with superior attention to detail to QA your own work, including cross-browser, cross-platform, and performance testing.
  • Passionate about software development, problem solving, and shipping well-tested code.
  • Deep understanding of design patterns to write reusable and modular code.
  • An exceptional communicator and collaborator to effectively work with both technical and non-technical peers.
Qualifications
  • 10+ years professional development experience delivering HTML, CSS and JavaScript based applications
  • At least 5+ years of experience with React
  • General understanding of UI design principles and best practices
