As a Senior Frontend Engineer in the Identity team, you’ll help us implement best-in-class authentication and authorization experiences.
What you’ll do
- Take ownership of features in our login and signup experiences. For example, build the frontend for the multi-factor-authentication device enrollment feature in our Next.js application written in TypeScript.
- Extend and maintain our OAuth2 and OpenID Connect client libraries for single-page applications (vanilla JavaScript and React), to match our platform’s capabilities and address feedback from other teams within the company. The libraries are written in TypeScript.
- Contribute to our continuous integration and delivery pipelines for our frontend stack, including end-to-end tests, within GitHub Actions.
- Collaborate with product engineering teams by assisting them with the integration into our identity platform.
- Mentor your fellow engineers.
- Participate in team rituals.

It would be a plus if
-
You have some backend experience with Node.js or Go. For example, you have worked with Express.js and understand basic concepts like middleware, request handlers, and routing.

- You have experience with authentication and authorization, for example because you integrated an application with an OAuth2 server
