Descripción del empleo

Join us to apply for the Senior Data Scientist role at Líbere Hospitality Group.

Founded in 2019 by the entrepreneurial team behind Ticketbis (acquired by eBay in 2016), Líbere is redefining stay experiences across Europe. By the end of 2025, we aim to operate 3,000+ tech-enabled units in six countries and generate over €35 million in revenue—a year-on-year growth rate of 90%.

Our vision is bold: to become Europe’s largest alternative to traditional hotels. We do this by blending contemporary design with frictionless technology to deliver stays that feel effortless and memorable.

Technology is at our core. From smart-building infrastructure to fully data-driven guest journeys, we’re engineering highly scalable, resilient systems that power:

• End-to-end automation (check-in, access, payments, support)
• Real-time operational insights for optimal pricing, occupancy, and maintenance
• Personalized guest experiences informed by rich behavioral data

The role

Join the team that manages 110,000+ price updates daily across 20+ properties in five countries. You’ll be the data lead for our dynamic pricing engine and the first point of contact for pushing the boundaries of data science in hospitality.

Why this role matters

• Immediate, visible impact: Every reservation, cancellation, or review affects your models within seconds, adjusting prices for thousands of guests.
• Full product ownership: From exploration to deployment, you’ll design, train, deploy, and monitor models that directly influence revenue.
• Green-field innovation: We’re exploring reinforcement learning, real-time inference, and elasticity modeling. You’ll help shape these initiatives and deliver initial versions.

What you'll work on

Revenue Management Platform:

• Maintain and evolve a neural-network-based demand-curve predictor retrained daily on millions of data points.
• Expand our feature set with competitor rates, city trends, and event signals via our in-house tagging pipeline.
• Manage training and inference on GKE + Argo Workflows; version control with DVC.
• Design pricing simulations triggering live updates after each booking—over 110,000 recalculations daily.
• Develop NLP models to classify reviews and identify issues affecting OTA scores.
• Provide insights to product, operations, and customer experience teams to close the feedback loop.

New frontiers:

• Prototype reinforcement-learning agents to learn optimal rate strategies under demand uncertainty.
• Implement and optimize price-elasticity models in production to balance margin and occupancy.
• Benchmark model performance and run A/B tests at various scales.

What we’re looking for

We seek a senior, business-minded generalist who selects the right tools, maintains elegant solutions, and is obsessed with measurable impact.

Must-haves

• Ownership mentality: setting goals, meeting deadlines, and standing by results.
• Autonomy: framing ambiguous problems and delivering insights independently.
• Neural network expertise: designing, training, and deploying models.
• Proficiency in Python (pandas, scikit-learn, TensorFlow/PyTorch) and SQL.
• Strong statistical foundation: translating business questions into hypotheses and selecting appropriate techniques.
• Production experience: shipping and monitoring ML models at scale.
• Cloud experience: working with GCP, AWS, or Azure.
• Knowledge sharing: curiosity, fast learning, and uplifting team skills.

Nice-to-haves

• Data engineering skills: Airflow, Argo, DBT, DVC, Terraform.
• Experience in hospitality, travel, or revenue management domains.

If you’re pragmatic, product-focused, and excited to scale the smartest pricing engine in hospitality, we want to meet you!

Our identity

We’re a remote-friendly, asynchronous culture that values transparency and speaking up. We believe in ownership, realism, and learning from mistakes. Your impact will be significant as we’re just starting up.

Rules are a good start—then break them.

DevOps culture: faster feedback leads to better results.
