Full Stack Developer

Role Overview

We are looking for a Senior Full Stack Developer to build and scale our fintech platform. You will own the entire lifecycle of our financial products, from designing high-performance relational schemas in PostgreSQL to building interactive dashboards in React.

Key Responsibilities

• Full Stack Development: Build and maintain end-to-end features using the PERN stack

(PostgreSQL, Express.js, React, Node.js).

• Database Optimization: Design complex relational models and optimize SQL queries to

handle high-volume financial data and audit trails.

• Security & Compliance: Implement rigorous security measures (e.g., JWT, OAuth, data

encryption) and ensure the platform adheres to fintech standards like PCI-DSS.

• API Architecture: Develop robust RESTful APIs to integrate with third-party banking APIs,

payment processors (Stripe/Plaid), and KYC providers.

Technical Requirements

• Front-end: Advanced proficiency in React.js (Hooks, Context API, Redux or TanStack Query)

and modern CSS (Tailwind/Styled Components).

• Back-end: Expert-level Node.js and Express.js experience, with a focus on asynchronous

programming and secure API design.

• Database: Deep knowledge of PostgreSQL (complex joins, indexing, triggers, and

migrations).

Additional skills

• Understanding of Event-Driven Architecture (using AWS SQS/SNS or Kafka).

• Familiarity with SOC2 or ISO 27001 compliance frameworks.

• Cloud (AWS): Proven experience with:

• RDS/Aurora for managed databases.
• IAM for secure access management.
• AWS Lambda & API Gateway for serverless architecture.
• CloudWatch for monitoring and alerting.

• Tools: Git, Docker, and experience with CI/CD workflows.

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.
