Frontend Software Engineer - Member Identity

ABOUT THE ROLE

Peloton is seeking a Frontend Software engineer with solid TypeScript and JavaScript experience to work on our User Platform team.

The User Platform team is responsible for the systems of authentication, authorization, user account data, and user profile security at Peloton. The team’s vision is to provide a platform for developers to easily integrate and deploy custom authentication flows in a secure manner. We seek to expand our IAM feature set to improve the user experience for existing customers, and streamline the signup process for new customers.

In this role, you will build new and improved authentication solutions for Peloton’s software. The role will involve working alongside client developers to add functionality that builds upon the User Platform team’s backend services.

To be successful you will need a combination of problem-solving, technical, and communication skills, and the ability to handle a mix of disparate tasks which will include project and software development work. As an Engineer in our squad, you will engage in constructive dialogue and seek resolution when confronted in technical discussions and solution designs. You will have the opportunity to learn from and be mentored by those who are building authentication at Peloton, and to influence authentication principles of our product.

YOUR DAILY IMPACT AT PELOTON

• Lead development for new authentication experiences on web platform
• Collaborate with client teams by working in an embedded role, providing technical guidance, or by writing libraries.
• Educate frontend developers on authentication principles, and how these relate to User Platform’s technical and product vision.
• Collaborate closely with other engineers, product managers, and designers, to determine the best solutions for User Platforms product goals.

YOU BRING TO PELOTON

• Deep experience with Typescript and JavaScript, including at least one client-side framework (e.g. React, Next.js, Vue, Angular).
• Strong understanding of web authentication fundamentals, using both sessions (cookies) and tokens (JWTs).
• Good communication skills that allow you to bridge the gap between frontend and backend developers, designers, and product managers.
• Strong software testing principles. You should have experience writing unit, integration and end-to-end tests and a strong sense of ownership.
• Experience with CSS fundamentals. You don’t need to be on the bleeding edge but you should understand the mental models.
• Experience with frontend build pipelines, including tools such as Webpack and Babel.
• Familiarity with designing backend REST APIs.
• Experience working with networking infrastructure used to build fault tolerant and scalable web systems (e.g. CDNs, DNS).
• An understanding of how to ensure that our web clients are performant, through good practices in the code itself and by making use of the tools listed above (CDNs, good API design, build tools/bundling).
