Full-Time MERN SaaS Developer

Job ID: 40251482

Budget: $15 – $25 USD

I’m building a new web-based SaaS platform and need an experienced MERN engineer who can take the product from architecture to production on a full-time, long-term basis. The core work centres on a true multi-tenant design, so a solid grasp of tenancy isolation, resource pooling, and per-tenant configuration is essential.

Key functionality we’ll be rolling out:
• User authentication with secure session handling and social/email log-ins
• Multi-tenant management that cleanly separates data while allowing a shared codebase
• Subscription billing with tiered plans, trials, webhooks, and proration logic

You’ll work with React (Vite or CRA), Node.js/Express, and MongoDB (Atlas). I already have a rough wireframe and database schema, but I’m open to your input on best practices, DevOps, and CI/CD. Daily collaboration will happen in GitHub, Slack, and Jira, and I expect clean, documented code with unit tests and frequent commits.

If you have launched SaaS products before, understand tenancy nuances, and can dedicate a full 40-hour week, let’s talk about timelines and milestones so we can push an MVP live quickly and iterate from there.
