• US Startup Availability: You are comfortable working late hours and staying responsive during critical festival launches.
• Mobile Awareness: Knowledge of mobile development (React Native) is a plus.
• English: Upper-Intermediate or higher. You must be able to explain complex technical trade-offs to the founders.

Responsibilities:

• Engineer the Core: Design and develop the backend and frontend for the Ticketing Platform.
• Solve Hard Problems: Implement logic for Reserved Seating, interactive maps, and complex order flows.
• Hardware & Gate Logic: Write code that interacts with the physical world (scanning tickets, printing).
• Performance: Optimize the app to handle traffic spikes during ticket sales drops.
• Quality & DevOps: Write testable code, manage CI/CD pipelines, and deploy to GCP. You break it, you fix it.

We Offer:
