Fintech Full-Stack Software Engineer

About the company

We are a leading Gulf-based retail and fintech company building consumer digital wallet products and merchant e-commerce tools. Our platform includes a live, Arabic-first consumer mobile app and a multi-tenant SaaS dashboard serving merchants, operated with a proactive regulatory and compliance posture. Our customers trust us with real financial value — correctness and security are not optional.

The role

You'll be one of the first engineering hires, working directly with the technical co-founder across the full stack: backend services, the consumer mobile app, and the merchant dashboard. You'll ship features end-to-end — from API design through deployment — on a product where every balance must be exact and every endpoint must be secure.

We're specifically looking for someone with a banking or financial institution background and a strong security mindset. You understand why a ledger must balance, why operations must be idempotent, and why every endpoint, upload, and login flow must be treated as a potential attack surface.

What you'll do

Build and maintain backend services (NestJS, TypeScript, PostgreSQL/Prisma, Redis, BullMQ)

Contribute to the consumer mobile app (React Native/Expo) and the merchant dashboard (Next.js)

Build and harden integrations: third-party e-commerce platform APIs (OAuth, webhooks), SMS/OTP providers, live market price feeds, and payment providers

Own transactional integrity for wallet operations: balances, audit trails, reconciliation

Apply security best practices across the stack: authentication and OTP flows, rate limiting, input validation, secure file handling, and protection of customer data

Participate in security reviews and hardening of existing services

Contribute to compliance-driven feature work (payments licensing, tax-authority integration, AML requirements)

Deploy and operate services in production (Linux, PM2, nginx, PostgreSQL migrations discipline)

Requirements

2–4 years of software engineering experience, including experience at a bank, payments company, or financial institution (core banking, digital channels, payments, or similar)

Strong TypeScript/Node.js; production experience with NestJS or a comparable framework

Solid security fundamentals: OWASP awareness, secure authentication and session handling, secrets management, and safe handling of user data and uploads

Solid relational database skills (PostgreSQL preferred) and disciplined handling of production migrations

Understanding of financial-grade engineering: idempotency, atomic transactions, reconciliation, and audit logging

React Native/Expo experience, including store submission and review cycles

Experience designing and consuming REST APIs and third-party integrations (OAuth flows, webhooks, token rotation)

Fluent Arabic and English

Additional requirements

Hands-on security experience: penetration testing exposure, security audits, or hardening work at a financial institution

Redis and background job queues (BullMQ or similar)

Familiarity with the Gulf fintech ecosystem: regulatory frameworks, local payment networks, open banking

Experience integrating with regional e-commerce platforms

DevOps fundamentals: nginx, PM2, CI/CD, server administration
