Full-Stack Engineer (NodeJS / NestJS / React / TypeScript) – B2B SaaS (4–6 YOE)

Remote (India) · Full-time · ₹10–20 LPA (DOE)

Product: Multi-tenant SaaS platform for UK clinics and pharmacies Why Script Assist

Script Assist is building the operating system for next-generation private healthcare in the UK. We power prescribing, dispensing, and operational workflows across clinics and pharmacies. Our platform runs real production workflows every day — this is not a prototype or early-stage MVP.

We operate in regulated environments where correctness and reliability matter. But we’re still a focused product team shipping features continuously. If you enjoy building real systems that people depend on daily — you’ll fit well here.

The Role

We’re looking for a strong full-stack engineer with meaningful production experience building real SaaS systems. You’ll work on a multi-tenant B2B SaaS platform used by clinics, pharmacists, and operations teams.

You’ll

Own features end-to-end

Work across backend and frontend

Ship production-grade code

Improve workflows that affect real users

Collaborate directly with product and operations

Prescribing and dispensing operations

Product catalogue and stock checks

Logging and monitoring

This is vertical SaaS complexity — not just basic CRUD dashboards. You do not need prior healthtech experience. If you’ve built complex B2B SaaS, fintech-style workflows, logistics systems, or other production systems with real operational logic — that experience is highly relevant. What You’ll Do

Handle validation, edge cases, and failure scenarios

We operate in an AI-first engineering environment.

We expect engineers to use AI tools intelligently for:

Planning and structuring work

Accelerating implementation

Strong hands-on experience building production systems

Real exposure to NodeJS and TypeScript in live applications
