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
