About Muzn IT

Muzn IT (muznit.com) is a product-focused IT and digital services company building enterprise-grade software for the GCC. We design, develop, and operate real SaaS platforms end-to-end — not throwaway projects.

Our product portfolio includes:

- Sufra Catering Management System — a full catering operations platform

- Laundry Management System (LMS) — serving thousands of residents in live production

- Muzn IT HRM — an enterprise HR management platform built for GCC organisations

- Muzn AI — an AI chatbot SaaS platform

- POS — an Electron-based point-of-sale system with thermal printing

- Client web platforms, portals, and WordPress solutions, etc.

We're now opening our Kolkata office as part of our India expansion — and you could be one of the first engineers to help shape it.

The Role: We're looking for a Senior Full Stack Developer who will take direct charge of developing all our products. This is a hands-on, high-impact role — you're the person who turns ideas into working, scalable, secure software.

You won't be one small cog in a huge machine. You'll lead features end-to-end, make real architectural decisions, and see your work go live quickly.

What You'll Do

- Design, build, test, deploy, and maintain our web and desktop applications end to end

- Work across the full stack — frontend, backend, database, APIs, and deployment

- Build new products from scratch and continuously improve existing ones

- Design clean database schemas, optimise queries, and keep performance sharp

- Develop and integrate REST APIs and third-party services

- Handle deployments, environments, and production support

- Debug complex issues and ship permanent fixes, not band-aids

- Uphold code quality, security, and engineering best practices

- Work closely with the founder and team to plan, prioritise, and deliver

Our Tech Stack

You should be strong across most of this (and eager to master the rest):

- Frontend: React, Vite, TypeScript, modern CSS/UI

- Backend: Node.js, Fastify/Express, Python

- Database: PostgreSQL, Supabase, SQL optimisation

- Desktop: Electron

- Infra & Tooling: Docker, Git/GitHub, Linux, CI/CD

- CMS & E-commerce: WordPress, Shopify, and similar platforms — must be able to build, customise, integrate, and maintain client websites and stores

- Bonus: Redis, job queues (BullMQ), pgvector / AI integrations

Development Policy — No AI Coding Tools

All development work must be completed independently without using AI tools to generate, write, autocomplete, modify, or debug code. Candidates must demonstrate strong hands-on coding skills, independent problem-solving, and the ability to design, develop, test, and maintain production-ready software without AI coding assistance. AI tools are not permitted for development tasks.

What Makes You the Right Fit: We want someone whose mastery shows in their work, not just on paper. The best candidate is:

- A genuine full-stack builder who can take a product from an empty repo all the way to production, solo

- Fluent in writing clean, efficient, maintainable code

- Strong in problem-solving, debugging, and system design

- Self-driven, accountable, and reliable in delivering on time

- Energised by startups, speed, and real responsibility

- Backed by 6 years of hands-on, real-world development experience

Please apply only if you genuinely love building — and can back it up with real projects.

Why You'll Love Working With Us:

This is the part that makes Muzn IT different. We treat our team like partners, not headcount.

- Profit share on every product we sell — when the products you build/collaborate on get sold to clients, you earn a share of each sale

- Profit sharing — as the company grows, your rewards grow with it

- Clear KPIs — know exactly what success looks like, and get recognised for hitting it

- A partner, not a number — you'll be trusted, valued, and treated as a core part of the team from day one, with your voice heard in real decisions

- Full transparency — open communication, honest numbers, no office politics

- A fun, energetic culture — we work hard and genuinely enjoy it, with team entertainment and downtime

- Personalised care — we give personalised service to our clients and to our people
