• Implementing QR code scanning for session linking
• Connecting to Global Payments + IDTech payment hardware
• Working with our hardware / software team to ensure real-time data sync with the PULSE dashboard and devices

This role is hands-on and highly collaborative — you’ll work closely with our lead engineer and leadership team to bring an industry-first product to market.

Qualifications

• Backend / API development experience (Node.js, Express, or Python / FastAPI)
• Solid understanding of RESTful API integration and database communication
• Experience with QR code scanning and hardware / API integrations
• Knowledge of authentication systems (Firebase Auth or JWT)
• Strong problem-solving skills and ability to work independently
