Job Description:
----------------

We are looking for an experienced developer to implement **Clerk.dev authentication** and integrate **Clerk Organizations** into our SaaS platform.  
We currently have a manual JWT-based authentication setup and are moving toward using Clerk as the primary identity and organization management system.

### Responsibilities:

*   Setting up **Clerk authentication** across our **NestJS** app (backend) and collaborating with our frontend developer as needed.
*   Migrating from our manual JWT setup to **Clerk-managed sessions**.
*   Implementing **Clerk Organizations** to allow multiple workspaces under a single user account.
*   Ensuring that API endpoints and server-side logic validate **Clerk-issued tokens** correctly.
*   Setting up **role and permission structures** within Clerk Organizations (e.g., Admin, Member roles).
*   Building smooth **login/signup, organization creation, invitation, and membership flows**.
*   Updating environment variables and deployment settings to securely manage Clerk keys and secrets.
*   Documenting the new authentication and organization management flow for future developers.

### Requirements:

*   Strong experience with **NestJS** (especially authentication, middleware, and guards).
*   Experience integrating **Clerk.dev authentication** into production applications.
*   Familiarity with **JWTs**, **session management**, and **OAuth2 principles**.
*   Experience working with **Clerk Organizations** or similar multi-tenant systems.
*   Solid understanding of **authentication security best practices**.
*   Ability to migrate and refactor existing authentication systems safely.
*   Familiarity with environment management and secure key handling (AWS, Doppler, etc.).

### Nice to Have:

*   Experience building **multi-tenant SaaS** systems.
*   Familiarity with **Stripe** or other billing systems tied to organizations.
*   Experience writing technical documentation (e.g., using **Swimm**).

### Tech Stack:

*   **Backend**: NestJS
*   **Frontend**: React
*   **Authentication**: Migrating to Clerk.dev (currently manual JWTs)
*   **Deployment**: AWS
*   **Database**: MongoDB Atlas

### Success Looks Like:

*   Seamless Clerk signup/login flow across the platform.
*   Single users can manage and switch between multiple organizations (workspaces).
*   Backend APIs securely validate Clerk sessions or tokens.
*   Clean, well-documented authentication and organization management code.

### Important:

Please apply **only if you are confident you can complete the work without needing to learn Clerk on the job**.  
We are looking for someone who can execute independently and deliver production-quality results. If the work is not progressing at a professional level, we will quickly move on to another developer.
