Job Description

We’re looking for a hands-on Full Stack Engineer who wants more than just closing tickets — someone who wants to own systems, understand the business, and grow into a Tech Lead.
At SATURDAYS, tech is directly tied to operations — from POS, inventory, warehouse, to customer platforms.
Your work will immediately impact real stores, real customers, and real revenue.
💡 What You’ll Do
  • Build and improve full-stack applications (frontend + backend)
  • Work on real business-critical systems (POS, inventory, internal tools)
  • Design APIs and integrate across multiple systems
  • Collaborate closely with Product, Ops, and QA
  • Debug and solve real production issues (not just dev environment)
  • Contribute ideas — not just execute tasks
🧰 Tech Stack
  • Backend: Node.js, Java / Kotlin (big plus if you have this)
  • Frontend: React.js
  • Database: PostgreSQL, MariaDB
  • Others: REST API, Docker
✅ What We’re Looking For
  • ~4+ years experience in software development
  • Strong in Node.js + React.js
  • Understand how systems work end-to-end (not just your part)
  • Comfortable working independently without being micromanaged
  • Able to think critically and challenge ideas when needed
  • Willing to take ownership and responsibility
⭐ Big Plus If You Have
  • Experience with:
    • Retail systems
    • POS or Warehouse Management Systems
    • ERP (especially ERPNext)
  • Familiar with TypeScript
  • Experience writing unit tests / end-to-end tests
  • Exposure to AI tools to improve productivity
🚀 Growth Opportunity
This role is designed for engineers who want to step up.
You’ll get the chance to:
  • Work closely with Tech Lead / Head of Tech
  • Be involved in system and architecture decisions
  • Grow into a Senior / Tech Lead role
⚠️ Reality Check (Important)
  • Hybrid working: 3 days WFO, 2 days WFH
  • You may need to jump in during production issues (non-office hours)
  • We move fast — ownership and responsibility matter here
💬 Who Will Thrive Here
  • You don’t like being spoon-fed
  • You care about why something is built, not just what
  • You want your work to actually impact the business
Bonus if you have experience working in high-ownership environments or small, fast-moving teams
