Senior Software Engineer - Alliron

About us

Líbere , as part of ALL IRON GROUP , was created by the founders of Ticketbis (acquired by eBay in 2016). What started as a bet on the largest alternative to hotels in Europe has grown into something bigger: +1500 units under operation, 6 countries, doubling revenue every year, and hitting break-even this year . 🚀

Our initial vision got validated along the way. We built a software platform to support a new modern operating model for hotels — and it works so well that we're now applying it to all our hotels and pivoting hard into this model because of how efficient it is at scale.

So now we're going one step further: we're spinning off the product as SaaS so any hotel chain willing to ride this crazy wave of changes can adopt it in a fast and reliable way. Big challenge for the team. Huge opportunity for whoever joins.

What we've built

After 5 years operating hotels with this model, we've turned what we learned into a platform built on five principles — and each one is an interesting engineering problem:

🛂 Autonomy — guests check in, access their room, and manage their stay without waiting for anyone. Making that work means a system reliable enough that 96% of stays complete without any staff intervention . Compliance, validation, and edge cases all resolved before arrival day, not at the front desk.

⚙️ Automation as the default — not a layer on top of manual workflows. The system drives the flow; humans handle explicit exceptions from a queue . We don't monitor timelines, we resolve exceptions. This is the part that flipped our whole engineering model.

🧩 All-in-one — pricing, policies, access rules, communications, distribution… one decision surface, applied everywhere. No third-party handoffs limiting how deep automations can go, which means cross-domain automations (housekeeping ↔ distribution ↔ pricing ↔ access) run natively. Plenty of meaty problems here.

📈 Chain-first architecture — most hospitality software was designed per-property and breaks at scale. Ours is built so configurations collapse into a small set of reusable definitions and inherit across the portfolio. Adding a property is cheap; the leverage compounds.

🪄 Zero-management — when the platform guarantees correctness, management becomes the exception, not the safety net. This isn't a slogan, it's a forcing function on every design decision we make.

And here's where AI clicks in

Our exception-driven approach toward zero-management turned out to be the perfect fit for the AI wave: automation → AI agent → HITL. We didn't pivot to "do AI" — AI just clicked into the architecture we already had. Most platforms bolt AI on top of manual workflows; ours was built for delegation from day one, so AI agents extend an already autonomous system instead of fighting it.

And we changed the way we build around it — not only how we code , but how we plan our w
