About flyvbird

flyvbird is building what traditional airlines never managed to build:

A demand-first, AI-driven regional air mobility platform.

Our platform is already live and operational. We combine:

Customer booking system (Next.js, TypeScript)

Admin Operations Console

API backend (Express.js, PostgreSQL)

ML service (FastAPI, scikit-learn)

Demand clustering & predictive routing (flyvAI)

We are now moving from Phase 1 “Human Algorithm” to Phase 2 autonomous AI optimization.

For this, we are building our own long-term in-house tech leadership.

Your Mission

You will take technical ownership of flyvAI and the entire booking platform stack.

This is not a feature-factory role.

This is a platform-stabilization, AI-evolution, and architectural leadership position.

You will:

Ensure platform stability in a business-critical environment

Eliminate structural weaknesses

Strengthen ML intelligence and automation

Prepare the system for scaling beyond 100k+ search events
