Senior Front-end React Developer

All offices

Remote

Senior Front-end React Developers play a critical role at Jobsity, they are responsible for implementing the front-end logic that defines the behavior of the visual elements of a web application. They are actively involved throughout the project lifecycle, often times starting with rapid prototypes early in the design phase. In some cases, the end goal is high-fidelity prototypes, but most of the time the developers will ultimately be writing clean, production-ready code, which will be integrated with the backend/APIs. Front-end developers are usually supported by back-end web developers, who are responsible for server-side application logic. They often work alongside other front-end web developers who specialize in markup and styling.

We are looking for a Senior Front-end React Developer who is passionate about design and programming. Responsibilities include implementing visual elements and their behaviors with user interactions. You will work with both front-end and back-end web developers to build all client-side logic. You will also be bridging the gap between the visual elements and the server-side infrastructure, taking an active role on both sides, and defining how the application looks and functions.

Requirements:

  • 5+ years working in front-end web development
  • Extensive programming experience in HTML5, CSS3, SASS or LESS, and Bootstrap, Foundation or Materialize
  • Excellent Javascript knowledge and programming experience with ES5/ES6
  • Solid understanding and development experience in ReactJS
  • Experience with tools like Redux, Webpack, Angular CLI and/or Gulp
  • Experience consuming REST APIs
  • TDD/BDD experience (Jest, Jasmine, Karma or Chai)
  • Experience with client-side architecture and design patterns
  • Awareness of cross-browser compatibility issues and client-side performance considerations
  • Solid understanding and extensive experience with version control tools like Git, SVN or Mercurial
  • Exceptional problem solving and ability to work independently
  • Exceptional learning skills
  • Fluency in both oral and written English

Nice to have:

  • B.S/M.S. in Computer Science or equivalent (Strong Computer Science fundamentals)
  • Experience with Typescript
  • Experience with NodeJS and ExpressJS, SailsJS or Loopback
  • Experience working with Docker or Vagrant
  • Knowledge of Photoshop or Sketch
  • Experience with mobile app development frameworks like Ionic or React Native

Staircase
//Consider a staircase of size n = 4: // # ## ### #### // //Observe that its base and height are both equal to n, and the image is drawn using # symbols and spaces. The last line is not preceded by any spaces. // //Write a program that prints a staircase of size n. // //Input Format //A single integer, n, denoting the size of the staircase. // //Output Format //Print a staircase of size n using # symbols and spaces. // //Note: The last line must have 0 spaces in it. // //Sample Input //6 // //Sample Output // # ## ### #### ##### ###### // //Explanation //The staircase is right-aligned, composed of # symbols and spaces, and has a height and width of n = 6.
Solve me First
//Complete the function solveMeFirst to compute the sum of two integers. // //Function prototype: //int solveMeFirst(int x, int y); // //where, // //x is the first integer input. //y is the second integer input // //Return values //sum of the above two integers // //Sample Input //x = 2 //y = 3 // //Sample Output //5 // //Explanation //The sum of the two integers and is computed as: 2 + 3 = 5.
Simple Array Sum
//Given an array of integers, find the sum of its elements. // //Input Format //The first line contains an integer, n, denoting the size of the array. //The second line contains n space-separated integers representing the array's elements. // //Output Format //Print the sum of the array's elements as a single integer. // //Sample Input //6 //1 2 3 4 10 11 // //Sample Output //31 // //Explanation //We print the sum of the array's elements: 1 + 2 + 3 + 4 + 10 + 11 = 31.
