At SMRT Systems, we don’t just build software — we build the infrastructure powering dry cleaning and laundromat automation worldwide. One of our flagship products, Bubblepay, is already redefining how laundromats operate. At Bubblepay, we’re building the future of laundromats. Yes, laundromats. (Don’t laugh — there’s real money in making washing machines smarter than your toaster.)

We’ve already launched:

• The biggest and best Android kiosk — both in interface and functionality (yes, we’re flexing).
• A Payment App that talks to machines and the cloud directly — webhooks are its love language.
• World-class, award-winning mobile apps (seriously, we took home the continent’s best design awards).
• A PHP + MySQL backend that makes scaling easy and cost-effective (practical beats fancy every time).
• An IoT network that keeps it all together, all the time (machines don’t get to take days off).

We’re lean, scrappy, and shipping faster than most “big tech” shops debating their next offsite. If you’re looking for cushy corporate vibes, keep scrolling. If you want to grind, ship, and see thousands of machines move because of your code — welcome home.

MUST-HAVE SKILLS

• React + React Native (bonus if you already know env setup & deployment tricks).
• Familiarity with MUI, Redux, and MQTT.
• PHP 8.1 + MySQL/MariaDB (our backend workhorse).
• Python for POC testing (Flask, Pandas, vibecoding welcome).
• At least one object-oriented language (C++, Java, .NET — pick your flavor).
• AWS/GCP services (IoT Core, Cognito, Lambda, RDS, CloudFront).
• Docker (multi-stage builds, containerized everything).
• Git (branch responsibly).
• Comfortable on Linux/MacOS.

GOOD-TO-HAVE SKILLS

• Building native Android modules (for when RN just says “no”).
• Playing with LLMs + MCPs (bonus if you can ship real AI-powered features).
• Hardware tinkering: Arduino, ESP32, Raspberry Pi (yes, laundromat robotics is a thing).
• CI/CD pipelines (so we don’t rely on “hope-driven deploys”).

THE ROLE

We’re looking for a Full Stack Developer to join our small but deadly dev team. You’ll be the kind of person who can bounce between React dashboards, React Native apps, and a Dockerized PHP backend without breaking a sweat.
One week you might be refining Bubblepay’s kiosk payment flow, the next you could be building a greenfield SMRT project from scratch. Either way, you’ll own features end-to-end.
Oh — and we like messing around with LLMs. Whether it’s building AI tools to help laundromat owners, or just experimenting to see if GPT can recommend better detergent, we want someone who’s not afraid to explore.

WHAT YOU’LL DO

• Ship across the stack: dashboards (React), kiosk app (React Native), backend APIs (PHP).
• Own features end-to-end — design, code, debug, and deploy.
• Debug MQTT topics, Stripe SDK quirks, and PHP Docker builds like a champ.
• Experiment with AI integrations where it makes sense.
• Work in a small, high-output team where your commits hit production fast.
