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.

I run a marketing agency that I started last year with a $4,000 loan and scaled to seven figures in annual revenue within 18 months. I'm hiring one person to work alongside me long-term and gradually take over key parts of what I do day-to-day.

This is a hands-on role on a fast-moving team, and you'll learn the exact systems behind that growth. (You can see how we operate on my YouTube channel.) www.youtube.com/@deweizhang9054

What you'll be doing

Taking over repetitive editing tasks I currently handle myself, following existing video tutorials and SOPs

Producing static image creatives, including AI-generated statics (e.g., with Nano Banana)

Strong technical integration background needed — connecting tools using APIs and webhooks, connect anythign amrketing related (Pixels, CAPI, GTM, Webhook, Zapier)

Working inside our marketing stack: lead-distribution software (e.g., LeadProsper, Leadshook) and funnel builders

This is intermediate integration work — not advanced heavy custom development.

Skills

Required

Technical integration skills: APIs, webhooks, CAPI, GTM, Pixels, and connecting marketing tools, Google spreadsheet (SUPER Important)
