Middle JavaScript Developer

A fashion e-commerce company with its own warehouse and logistics operations is looking for a Middle JavaScript Developer to work across three codebases: a modern Nx monorepo (Next.js, React, TypeScript, tRPC), a consumer storefront (Next.js with Capacitor), and a legacy PHP WMS portal being migrated. The role involves end-to-end feature development, maintenance of hybrid mobile apps, and building AI-powered automation.

• Ship features across the portal monorepo end-to-end: UI, tRPC API, SQL, tests, stage verification
• Maintain and extend the consumer storefront and its iOS/Android hybrid apps
• Migrate functionality out of the legacy PHP monolith: read the old code, understand the real behaviour and data, rebuild it properly in the modern stack
• Build and improve AI-powered workflows: invoice extraction, visual product search, LLM-driven automation, neural recommendations
• Diagnose production issues with logs and data before writing code, and back proposals with real numbers

• 3-5 years of commercial experience with React, Next.js, and TypeScript
• Experience in e-commerce or FinTech domains
• Comfortable in monorepo architecture (Nx or Turborepo)
• Solid SQL (MySQL preferred) — you can write and reason about multi-table joins and indexes without an ORM — plus working knowledge of Redis
• Hands-on AWS experience (at minimum S3, SQS, and ECS or Lambda)
• LLM/AI fundamentals — prompting, embeddings, RAG patterns — enough to build and debug AI features
• Daily, deliberate use of AI-assisted development tools, and the judgment to articulate when they help vs hinder
• Able to read and reason about legacy PHP to inform migration decisions
• Proven fast ramp-up in complex, under-documented codebases; autonomous ownership of tickets from diagnosis to deployment

• 18 working days of paid vacation a year
• Plus 3 days of additional vacation for childbirth and marriage
• 7 days of paid sick leave per year
• 7 public holidays off
• Corporate team-building events & celebrations
• English classes covered by the company
• Healthcare program
• Access to learning: internal/external, certification compensation
• Development roadmaps and plans to support your professional growth
• Regular performance reviews
• Full accounting support
• Participation in the IT Cluster
