About Us
We are redefining how people will book travel via AI agents. Our SaaS platform built around MCP servers lets airlines, hotels sell through AI assistants like ChatGPT, Gemini, and voice agents. Our founding team is composed of successful repeat founders in the travel industry that have scaled companies in the past. You’d be one of our first engineers (#1–3), helping shape the tech, culture, and product from the ground up.

AI Integration: Manage the development and optimization of the MCP for various AI assistant platforms, including ChatGPT, Gemini, and Claude. This also includes establishing a standardized testing and validation process for the MCP server.
Backend: Pick the right data models, set up Postgres and vector databases, design APIs (GraphQL/REST), and automate deployments on GCP.
Architecture: Balance speed, quality, and cost while setting up coding standards, testing, and monitoring.
Teamwork: Work closely with founders, designers, and product managers to turn user feedback into awesome features.
Tech Stack
Here’s what we’re working with (or planning to):
Frontend: TypeScript, React/Next.js, Tailwind
Backend: Node.js, Golang
AI/LLM: OpenAI, Anthropic, Gemini, PGVector/Pinecone
Infrastructure: GCP, Terraform, GitHub Actions
Data: Postgres, Redis, Airflow

Experience taking features from ideas to live in a fast-paced setting.
Great English communication, comfortable chatting with users and non-tech folks.
Bonus Points
Worked with LLM tools (LangChain, LlamaIndex), RAG, or multi-agent systems.
Know your way around travel APIs (Amadeus, Sabre, Booking, etc.).
Familiar with GraphQL, event-driven systems (Kafka/PubSub), or Kubernetes.
Been part of an early-stage startup before.
