Job Description

We're looking for a problem-solver first, developer second.

In this role, you won't just be writing code from a spec. You'll be thinking through features, anticipating edge cases, and building systems that actually work in production. When we say "build a voucher system," we expect you to ask: What's the max per customer? Is there a global cap? What happens when it expires mid-checkout? Can it stack with other discounts?

You'll work on real-world logistics, retail, and operational challenges powering a fast-scaling laundry-tech platform. Our tech stack includes:

• Backend: Laravel PHP, Node.js/Express with TypeScript & Prisma (microservices architecture)
• Frontend: Next.js 15 with React, TypeScript, Tailwind CSS
• Databases: MySQL, PostgreSQL, Redis
• IoT Services: Python (FastAPI/Flask) for machine integrations via Modbus protocol
• Infrastructure: Docker, queue workers (Beanstalkd), Firebase, AWS S3

This role is NOT for you if:

•  You wait to be told exactly what to build
•  You struggle to debug issues independently
•  You've never thought about edge cases before they became bugs in production

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

What You'll Actually Do

•  Design and implement features end-to-end – from understanding the business problem to thinking through edge cases to writing clean, maintainable code
•  Debug and troubleshoot – we need someone who can trace through logs, reproduce issues, and fix root causes (not just symptoms)
•  Think before you code – document your approach, consider failure modes, and propose solutions before jumping into implementation
•  Collaborate across teams – work with frontend/mobile engineers, ops, and business stakeholders to ship features that actually solve problem

Job Requirements

Requirements

•  2–5 years of hands-on PHP/JS stack development
•  Strong problem-solving skills – you can break down ambiguous requirements into concrete implementation steps
•  MySQL query optimization and indexing at scale
•  Experience with RESTful APIs and Microservice architecture
•  Comfortable debugging in production – you know how to trace issues through logs, queues, and database queries
•  Git flow version control and structured deployment experience

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Nice to Have

•  Experience with Live-service applications >100k+ concurrent users at scale
•  Microservices architecture and service-to-service communication
•  Familiarity with Redis, queue workers, and job scheduling
•  IoT device integration or hardware protocols (Modbus, serial communication)
•  Docker, containerization, and cloud deployment (AWS, DigitalOcean)
•  Linux CLI, bash scripting, and DevOps practices
•  Can communicate technical concepts clearly to non-technical teams

How We Evaluate

We don't just test coding ability. Our interview process includes:

Technical Discussion – Walk us through a feature you've built. Show us your code, explain your decisions, demonstrate how it works.

Problem-Solving Exercise – Given a business requirement, show us how you'd think through the design, edge cases, and implementation approach.

Debugging Scenario – Show us how you'd approach diagnosing and fixing a real production issue.

We're looking for engineers who think ahead, not just developers who write code.
