Software Engineer

Job

Overview

We are hiring engineers who build with agents, not just with editors.

Mumzworld is the largest mother, baby and child e-commerce platform in the Middle East - millions of customers, a deep catalogue, and a stack that has to stay fast, correct and cheap at scale. We are rebuilding how our engineering team works around AI: agents write, review and test alongside us, and the engineers who compound fastest are the ones who know how to direct them.

This is a backend-heavy full stack role. You will own services end to end - schema to API to the React surface that consumes it - and you will be expected to ship at a pace that only makes sense if you are genuinely fluent with modern AI tooling.

Key Responsibilities

• Own backend services end to end. Design, build and operate NestJS/TypeScript services on PostgreSQL - data modelling, APIs, background jobs, caching, observability, on-call for what you ship.
• Close the loop on the frontend. Build the React interfaces that consume your APIs. You should be comfortable shipping a feature all the way to the customer without a handoff.
• Work at real e-commerce scale. Catalogue, cart, checkout, pricing, promotions, inventory, order orchestration - systems where correctness and latency both matter, in two languages and multiple markets.
• Build with agents by default. Use Claude Code and similar tooling as a core part of your workflow: planning, implementation, refactors, test generation, migrations, incident triage.
• Make the team faster, not just yourself. Author agent skills, subagents and workflows that other engineers reuse. Wire up MCP servers to our internal systems. Turn tribal knowledge into tooling.
• Ship AI into the product. Build LLM-powered features - search and discovery, content generation, support automation, merchandising assistance - with proper evals, guardrails and cost/latency budgets.
• Raise the bar on quality. Strong code review, meaningful tests, and a healthy scepticism about agent-generated code that looks right.
