About US

RJ Fintech Solutions Pvt. Ltd. is a high-growth fintech startup on a mission to automate business financial operations. In a world where financial systems are often slow and opaque, we are building the "missing link"—a secure, transparent, and lightning-fast platform that puts banking and compliance first for various corporates.

We are not just another financial app; we are an engineering-first company. We believe that elegant code and robust architecture are the foundations of trust. By leveraging the PERN stack and AWS cloud-native infrastructure, we are replacing legacy complexity with modern, scalable solutions.

Why Work With Us?

1. Build the Foundation, Not Just Features

You won't be a small cog in a massive machine. As an early member of our engineering team, you will help define our technical architecture, choose our libraries, and set the coding standards for everyone who follows. Your fingerprints will be on the core DNA of our product.

2. Solve Problems That Matter

Fintech is one of the few industries where code has a direct, measurable impact on people's lives.

Whether we are [e.g., simplifying cross-border payments, democratizing investment, or building the next generation of credit], you will be solving high-stakes challenges around security, trust, and financial inclusion.

Role Overview:

We're looking for a Senior Full-Stack Developer who doesn’t just write code—but builds systems, owns features end-to-end, and leverages AI tools to move fast and build smart. This isn’t a ticket-taking role. This is for builders who can architect, develop, and ship independently, with a bias toward action and clarity.

If you live inside your terminal, talk to Co-pilots like your pair programmer, and obsess over clean APIs and smooth user flows—let’s talk.

What you’ll do

• Take full ownership of features from problem → design → code → deploy → iterate
• Build modular, scalable APIs and frontend components using the MERN stack
• Use AI tools to write, debug, optimize code, and unblock yourself fast
• Integrate 3rd-party APIs, services, and AI capabilities where relevant
• Collaborate async with product, design, and other engineers
• Optimize performance, scalability, and dev workflows
• Own dev hygiene—documentation, tests, Git practices, CI/CD pipelines

Must-Haves:

• Bachelor’s degree in Computer Science, Engineering, or a related technical field
• 4–5 years of full-stack experience in production-grade MERN apps
• You’ve shipped products end-to-end, not just maintained features
• Strong in JavaScript/TypeScript, both on frontend and backend
• Solid foundation in system design, API design, and debugging
• Comfortable using AI-native tools to code faster and better
• GitHub is your second home. You write clean commits and structured PRs
• Cloud/infra experience (Vercel, AWS, Docker/Kubernetes)
