Our client is an early stage startup headquartered in Zurich. They are building AI infrastructure that sits at the core of how large enterprises operate. You'll work directly on the product with real impact from day one. Meaningful equity on offer for the right person.

Requirements

- Practical knowledge of integrating and orchestrating LLM providers, building AI pipelines, and managing state machines in production environments.

- Ability to talk directly to customers, identify problems, and translate them into shipped solutions fast.

- You know when to build the right abstraction and when to just ship. You take full accountability for everything you build, from Terraform to UI.

Responsibilities

- Architect and maintain Python services that orchestrate LLMs, handle state machines and integrate with legacy infrastructure

- Own the full vertical of every feature you ship, from infrastructure and backend logic to frontend and deployment.

- Act as the bridge between AI capabilities and real world workflows, turning messy email based processes into clean automated transactions.

- Manage and evolve the orchestration layer that enables AI agents to negotiate, quote, and execute high-value travel bookings autonomously
