Boulder, San Francisco, Remote US, London, New York City

Job description

What the team looks like 

You'll be joining a community of 30+ engineers, grouped into sub teams with specific domain focus. The team is made up of hardworking people from all over the world. We work from London, San Francisco, Boston, Colorado and New York, and as well as collaborate with folks remote across the United States. We welcome people from all backgrounds.

We represent a wide range of experience and interests, and we all agree to do three things well:

  • We strive to build a strong team that allows us to do and learn more than we could as individuals. Being inclusive is a part of our team's culture and community.

  • We collaborate to create a codebase that is a joy to work in and will be for years to come. We have a strong commitment  to accessibility. Let's be responsible together.

  • Our goal is for Twitter to be one of the world's most performant web apps/PWAs. Speed is a crucial feature for everyone, and we measure our success by the performance of our application.

We're a thoughtful and motivated team, that despite being relatively small, has a large impact on the world and the company. Your skill and passion will be appreciated and rewarded here. 

Who You Are

  • First off, you don’t need a Computer Science degree to apply. We encourage people from both CS and non-CS backgrounds with equivalent work experience to apply.

  • You are an engineer with 2+ years experience in industry. 

  • Not only strong technically, you have shown that you can work effectively with product managers, designers and other engineering teams.

  • You have a fierce sense of ownership, caring deeply about the quality of everything that you deliver into your customers' hands.

  • You love the challenge of engineering, and are confident in your ability to bring clarity and direction to ambiguous problem spaces.

  • You work well in a fast paced environment while deeply investing in long term quality and efficiency.

  • You're passionate about teaching: We put a high value on learning from each other. You should be skilled at pairing, teaching and sharing things that you've learned.

  • You've got empathy and self-awareness: The foundational trust of all strong teams relies on understanding yourself and others.

  • You work as part of a team, including engineers in remote offices

  • You take a collaborative approach to work and can incorporate feedback from product, design and your engineering peers

  • You care about web accessibility: we want to reach everyone everywhere!


What You’ll Do

We want you to find work that aligns with both your career goals and the goals we have for Below are the kind of things we would like you to work on:

  • Get to know your peer developers to understand their challenges in day to day work so that you can move quickly and with empathy to improve all aspects of their work.

  • Work with Twitter's infrastructure to ensure that our Node server is running efficiently, our work can be reused by others across the company (or world), and explore opportunities for using our work in new ways (e.g what would it look like for us to support a server rendered tweet?)

  • Work closely with teams across product engineering, product management and design to build features that affect millions of users daily. 

  • This job is more than JavaScript. Your non-coding skills (Communication, Mentoring, Project Management, etc) are very important. We believe that leadership comes from everywhere, and it's important that our Senior Developers have the skills to lead complex projects successfully within a large organization.

  • Familiarity with or interest in learning any of the following is a plus: React, Webpack, Babel, ES6, Node/Express, SSR, React Native, Redux, React Router, GraphQL


  • B.S. or higher in Computer Science  (or equivalent work experience)

Nice to Haves

  • Great communication and documentation abilities

  • Experience working with accessibility issues

  • Data-informed product development: analytics, A/B testing, etc.

  • Links to open source contributions or any public code

If this sounds like a team you want to be a part of, great! We are looking for an engineer who loves writing code, has a strong desire to learn, and wants to collaborate with teammates who are committed to serving their customers.
