Founding Senior Engineer [Full Stack / Product]

THE MISSION

Over $300B+ in complex travel bookings still depend on manual workflows. While the world moved to APIs, high-stakes bookings (weddings, conferences, group travel) are still handled by humans manually typing data from messy emails into legacy systems.

Lobby is the orchestration layer that fixes this. We are not building a chatbot; we are building AI agents that negotiate, quote, and execute transactions directly within the core infrastructure of global travel brands.

THE CHALLENGE

As a Founding Full Stack Engineer, you aren't "building features", you are building a new category of software. You will:

• Bridge the Gap: Create sleek, high-utility React interfaces that make complex AI agents feel intuitive to non-technical hotel staff.
• Architect the Engine: Build Python services that orchestrate LLMs, handle state machines, and talk to legacy APIs.
• Ship End-to-End: From the terraform script to the z-index fix; You own the entire vertical slice of what you build.

YOUR STACK

We value boring technology used for exciting problems. We optimize for shipping speed:

• Frontend: TypeScript, React, Tailwind.
• Backend: Python (FastAPI/Django), Node.js, PostgreSQL, Redis.
• Infrastructure: AWS, Docker.
• The "AI" Layer: Integration with LLM providers and custom orchestration logic.

MUST HAVES

• Seasoned Builder: Minimum 8 years of experience as a software engineer (fullstack, or at least more backend / infra heavy).
• Startup DNA: You have worked at a startup before, in a small team, and you know what it means to ship without layers of process around you.
• Full-Spectrum Capability: You are equally comfortable debugging a race condition in Python as you are centering a div or optimizing a React hook.
• Product Intuition: You do not need a 20-page PRD. You can talk to a customer, understand their pain, and sketch + ship a solution by EOD.
• Pragmatic Generalist: You know when to write a perfect abstraction and when to "just make it work" to hit a deadline.
• Swiss-Based/Local: You want to be on the ground in Zurich, building alongside the founders in a high-intensity environment.

WHY LOBBY?

• Extreme Autonomy: No "Middle Managers." No "Agile Coaches." Just builders, customers, and code.
• Market Pull: We are tackling a massive, un-sexy problem that is desperate for a modern solution. The "Why Now" is obvious once you see the product.
• Founding Equity: You get a seat at the table, not just a desk.

HOW TO APPLY

Do not send a formal cover letter. Send us:

• A link to a GitHub repo or a live product you are proud of.
• The most "hacky" thing you have ever done to ship a product on time.
