What are some common challenges faced by JavaScript Web Developers when working on cross-browser compatibility?

JavaScript Web Developers often encounter challenges ensuring that web applications function consistently across different browsers and their various versions. Differences in how browsers interpret JavaScript, handle CSS, or support certain APIs can lead to unexpected bugs or display issues. To overcome these challenges, developers frequently use polyfills, transpilers like Babel, and thorough testing on multiple browsers and devices. Collaborating with QA teams and staying updated on browser release notes are also important strategies to maintain compatibility and deliver a seamless user experience.

What is the difference between Javascript Web Developer vs Front-End Developer?

Work EnvironmentWeb development teams, software companiesWeb design agencies, tech firms

Javascript Web Developers specialize in coding and optimizing JavaScript functionalities, while Front-End Developers focus on creating the visual and interactive aspects of websites. Both roles often overlap, but the Javascript Web Developer emphasizes scripting, whereas the Front-End Developer emphasizes design and user experience.

What does a JavaScript Web Developer do?

A JavaScript Web Developer specializes in using JavaScript to create interactive and dynamic features on websites and web applications. Their work often involves developing front-end user interfaces, integrating APIs, optimizing website performance, and sometimes working with back-end technologies like Node.js. They collaborate closely with designers and other developers to ensure a seamless user experience. Additionally, they stay updated with the latest JavaScript frameworks and best practices to deliver efficient and scalable solutions.

What are the key skills and qualifications needed to thrive as a Javascript Web Developer, and why are they important?

To thrive as a Javascript Web Developer, you need strong proficiency in JavaScript, HTML, and CSS, often backed by a degree in computer science or a related field. Experience with frameworks like React or Angular, version control systems such as Git, and knowledge of build tools and package managers are typically required. Problem-solving skills, attention to detail, and effective communication help developers excel in team environments and deliver user-friendly solutions. These skills ensure the creation of efficient, maintainable, and high-quality web applications that meet both business and user needs.

Job description

Make your mark at Comcast -- a Fortune 30 global media and technology company. From the connectivity and platforms we provide, to the content and experiences we create, we reach hundreds of millions of customers, viewers, and guests worldwide. Become part of our award-winning technology team that turns big ideas into cutting-edge products, platforms, and solutions that our customers love. We create space to innovate, and we recognize, reward, and invest in your ideas, while ensuring you can proudly bring your authentic self to the workplace. Join us. You'll do the best work of your career right here at Comcast. (In most cases, Comcast prefers to have employees on-site collaborating unless the team has been designated as virtual due to the nature of their work. If a position is listed with both office locations and virtual offerings, Comcast may be willing to consider candidates who live greater than 100 miles from the office for the remote option.)

Job Summary

As a Principal Software Engineer on the JavaScript Player-Platform team, you will develop client-side libraries that are used by millions of people to stream Live, On-Demand, and Recorded content on desktop web browsers, casting-enabled devices, and dozens of Smart TVs and Set-Top Boxes

Job Description

Player-Platform JS is an SDK written in Typescript, that powers the IP video playback experience on the X1 Platform set-top boxes, and Xfinity Stream on many platforms. It provides a video player that integrates with our video streaming, content protection (DRM), advertisement, emergency alert, and real-time analytics services. Player-Platform strives to provide a high quality, consistent playback experience across all our integrations.

Who will you work with?

Player-Platform software engineers collaborate with industry experts from many subject areas: software architects, software engineers, data scientists, and other video streaming technologists. Daily, you will be working on a small scrum team that consists of product owners, software engineers, automation engineers, and quality assurance engineers. You will work closely with other technical teams internal and external to Comcast VIPER

What are some interesting problems you'll be working on?

The JavaScript Player Platform is integrated into a high number of environments with a complex requirement surface area. The complexity we face in integration is closer to an enterprise system than it is to a video player app. Designing toward and executing on more flexible APIs and implementations to allow us to expand our integration footprint will be a constant focus.

Working to improve the reliability, and features of our IP Video customers, and give our multi-billion dollar advertising business a driven edge, are also a central focus.

Where can you make an impact?

Your code will be responsible for all IP video playback streaming that is done at Comcast. It will be run on customers' devices millions of times a week and will be the primary Comcast product that they interact with. You can help improve our video playback experience by developing the most stable, and the highest quality video player in the industry. You'll be working with the brightest minds in Comcast building a video platform that will power Comcast for years to come. You will drive the future of the IP video industry.

What You'll Do:

  • Build clean API's for video playback on supported devices
  • Work with HTML5 video Media Source and Encrypted Media API Extensions (MSE & EME)
  • Build reusable software components in TypeScript
  • Design and implement end to end components related to video playback
  • Analyze, optimize, and improve the code base
  • Demonstrate personal and team leadership by showing dedication to integrator and customer success
  • Support operations personnel in maintaining a high standard of reliability.
  • Regular and consistent attendance.
  • Other duties and responsibilities as assigned.

What You'll Need:

  • 10+ years software development experience with some experience with Java Script application development or other related programming languages.
  • Bachelor's Degree preferred or equivalent experience.
  • Computer science fundamentals
  • Can solve hard problems quickly by writing code
  • Knowledge of JavaScript within Web Browsers strongly encouraged
  • Experience designing clean, concise, maintainable APIs
  • Experience with HTTP video a plus
  • Good communicator and able to clearly articulate complex issues and technologies
  • Familiar with a scripting language
  • Ability to design, develop, and integrate a solution to completion
  • Comfortable working in a fast paced agile environment
  • Customer and team-focused attitude

Employees at all levels are expected to:

  • Understand our Operating Principles; make them the guidelines for how you do your job.
  • Own the customer experience - think and act in ways that put our customers first, give them seamless digital options at every touchpoint, and make them promoters of our products and services.
  • Know your stuff - be enthusiastic learners, users and advocates of our groundbreaking technology, products and services, especially our digital tools and experiences.
  • Win as a team - make big things happen by working together and being open to new ideas.
  • Be an active part of the Net Promoter System - a way of working that brings more employee and customer feedback into the company - by joining huddles, making call backs and helping us elevate opportunities to do better for our customers.
  • Get results and growth.
  • Respect and promote inclusion & diversity.
  • Do what's right for each other, our customers, investors and our communities.

The VIPER team is an organization within Comcast's grander Technology Product and Experience organization (TPX) which supports the Product Management, Research & Development, Engineering and Operations for Comcast's Elite Video Experiences in use by Comcast and Syndicated Partners.
