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.

What role will you play? 

As a Full Stack Engineer, you will play a pivotal role in our development team, bridging the gap between the visual elements and the server-side infrastructure. You will be instrumental in developing full-fledged, scalable applications by combining the art of design with the science of programming. With your expertise in both front-end and back-end technologies, you will ensure the entire stack is designed and built for speed and functionality.  

Your day to day will involve designing and developing dynamic, high-quality web applications, leveraging the Node.js and python for the back end services and React/Angular for the front end. Close collaboration with UI/UX designers will be essential, allowing you to bring web designs to life while ensuring high performance and responsiveness. Additionally, you will actively participate in coding, debugging, and testing to deliver reliable solutions whilst also working closely with other developers, designers, and product managers, fostering a collaborative environment to meet project goals and deadlines effectively. 

What you offer 

• Proficiency in Typescript and a good understanding of React  
• Solid experience with the Node.js, including the ability to develop RESTful APIs 
• Experience with containerisation of service using Docker 
• Knowledge of modern authorisation mechanisms, such as JSON Web Token (JWT)  
• Familiarity with SQL databases, such as PostgreSQL 
• Experience with Kafka or other event driven tools and tech 
• Nice to have some experience integrating with LLMs through open AI, Gemini etc. 
• Nice to have exposure to AI tooling – Claude, Copilot, Cursor etc. 
• AWS experience is a nice to have
