The Position

Who We Are

Our vision is to lead the industry in building trust through powerful, easy-to-use tools and features that provide transparency and give control to our customers over their experience and data. We have strong customer focus – we connect directly with customers who are using our products, and use their guidance to make meaningful improvements.

On the healthy content engineering teams you have the opportunity to have significant ownership and impact over major user-facing features.

You will join a  team that is passionate about building user-facing consumer integrity products to ensure our users healthy participation on Twitter – while reducing the amount of unhealthy content (abusive, toxic, illegal) on the platform.

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

  • You are an engineer with at least 5 years experience in industry.
  • 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.
  • 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!
  • You have experience leading projects not only within your team but cross-functionally as well


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)
  • 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
