Howdy 👋 We are glad you made it!
We are in the hunt for strong full-stack typescript developers to join our Developer Experience team! You are proficient in React and have a strong engineering mindset. You understand the depth of web technologies, data structures, communication protocols and architectures, state management and have passion (and good eye) for building absolutely mind-blowing, 2024-worthy user experiences.
You can autonomously work on your BFF with Node.js consuming data services from databases, pubsubs and other services provided by the data teams.
And don't be shy! We place great value in education and experience; but we also recognize that talent is built on passion and hours dedicated to deliberate practice and learning... so don't shy away from applying if you feel you have what it takes!
You need to build an authentication screen and its supporting API with React and Node.js The module needs to support a dynamic MFA validation besides the usual user/password set.
Here is the expected flow in a nutshell:
- A user comes to the login page and enters its email
- If no user with the required email exists, just create it
- If the user has not been active for more than 7 days, ask for a one-time-password
- It must be 6 digits, the API should print it in console.log for challenge validation purpose -- no need to plug an actual email delivery system or any other form of MFA token delivery.
- If the user has no password (was newly created), ask for a new password and set it
- On success, return the JWT tokens to be further used by the user
- If the user has a password, ask for the password.
- On success, return the JWT tokens to be further used by the user
You are free to structure the API, style the UI and add whatever you see fit to deliver (from libraries to animations to backend frameworks). There are no restrictions on your weapons of choice as long as you stay within the React+Node.js universe.
Here's a little example flow in case you need a little push to get going:
sequenceDiagram
FE ->> BFF: { email: '[email protected]' }
BFF ->> FE: { session: <session-hash>, challenge: 'validate-email' }
FE ->> BFF: { session: <session-hash>, secret: '123456' }
BFF ->> FE: { session: <session-hash>, challenge: 'set-password' }
FE ->> BFF: { session: <session-hash>, newPassword: 'FU(iolkevn23$90' }
BFF ->> FE: { status: 'OK', jwtToken: {...}}
- This is your presentation letter. Don't shy away from adding whatever extension to the requirements you think would be interesting to discuss during the technical interview.
- We use Kotlin for our backend services (except for the BFF's which are done in NestJS). You can get trained on the job, but doing the backend part of this assignment in Kotlin or Java will earn you some extra points.
Once you are happy with it, zip it and send it to [email protected] for us to review.
The repository already contains a usable skeleton for the react application and express API setup with NX. Feel free to change it for a Next and/or Nest frontend or backend if you are more comfortable with those frameworks.
