About Project

A fashion e-commerce company with its own warehouse and logistics operations. The engineering team builds the platform end-to-end, including the customer storefront, warehouse management portal, and AI-powered automation. The main goal is to fully automate warehouse operations and minimize manual decision-making.

The role

You will work across three interconnected codebases at different maturity levels:

  • a modern Nx monorepo — Next.js 16, React 19, TypeScript, tRPC (the main portal: 8 apps, 12 shared libraries, layered architecture)
  • a consumer e-commerce storefront — Next.js 14 with Capacitor native apps
  • a legacy PHP WMS portal (CodeIgniter 3, ~46K commits) being incrementally migrated into the modern stack


Must-have qualifications

  • 2+ years of commercial experience with React, Next.js, and TypeScript
  • 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


Nice to Have
​​​​​​

  • tRPC or similar end-to-end type-safe API experience
  • E-commerce or warehouse/logistics domain knowledge
  • Capacitor / hybrid mobile experience
  • AWS CDK or Terraform (IaC)
  • Playwright or Cypress E2E testing

What you will do

  • 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

What we offer:

  • 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​
