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.

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.

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.

Responsibilities:

• Work as part of a collaborative, agile team to deliver industry-leading engagement capabilities on the web.
• Integrate with other services to help the client seamlessly provide value to more companies.
• Design and develop feature enhancements that continue to deliver value and provide an excellent customer experience.
• Troubleshoot and resolve emergency server or code issues at any stack level.

Requirements:

• Ability to empathize with end-users; build with scale and ease of adoption in mind.
• Experience building in an agile setting with code reviews and quality as a priority.
• Strong design skills for separation and modularity of code; aversion to overly complex, spaghetti code.
• A bachelor's degree in Computer Science, related technical field, or commensurate experience.
• 3 years experience in production web application development.
• 5 years of experience working with NodeJS or an equivalent web framework and language.
• Experience writing JavaScript code, either vanilla JS or using a framework such as Node.js or React, or Redux.
• Unit testing experience (Jest).
• 3rd-party API usage and integration experience.
• RDBMS usage (e. g., MySQL, PostgreSQL).

Interview Process:

• Introductory Round
• Technical Round - Algo/low level coding round based on real world scenario
• Technical Round - System Design or High level design coding round and AWS
• Offer discussion
