[Hiring] Data Scientist @Flix

Role Description

We are looking for an experienced Data Scientist to engage with Flix on a freelance/service agreement basis (B2B contract). This is a contractor engagement for a professional who wants to work on impactful, hands-on data science challenges like:

• Estimating price elasticity from noisy booking data
• Testing new demand signals
• Turning a sound method into a model that runs in production

Scope of Services:

• Bring expertise in data science and quantitative analysis to work within Flix's Revenue Management System and build demand forecasting and price elasticity models.

About the Engagement:

• Further develop demand forecast and price elasticity models that drive automatic pricing across the Flix network.
• Research and test improved approaches to modelling price elasticity — from first hypothesis to validated, production-ready model.
• Act as a subject-matter expert partner for forecast and pricing models, advising product and business counterparts on problems, solution ideas, and feasibility.
• Actively contribute your ideas to technical brainstorming and modelling discussions as an advisor.
• Effectively collaborate with others to implement solutions and ensure they are practical to operate reliably in production.
• Monitor and analyse the behaviour of pricing products and respond to support cases.
• Contribute to the technical health, reliability, and observability of the existing system.

Qualifications

• Strong academic background in mathematics, physics, statistics, operations research, quantitative economics, or a related field, with a solid grounding in statistics and data analysis.
• Alternatively, proven hands-on expertise in price elasticity or demand modelling, for example from pricing or revenue management in transport, travel, hospitality, or retail.
• Critical thinking and attention to detail: You question assumptions, check your results, and derive your own solutions in a complex environment.
• Programming experience — preferably Python; strong background in another language is acceptable.
• Good SQL skills.
• Basic knowledge of machine learning.
• Strong communication skills to explain your approach and results clearly to technical and non-technical colleagues.
• You implement your models yourself and care that they run reliably.
• You enjoy working with others, and you can build resilient working relationships with your stakeholders, even in a remote setup.

Requirements

• Cooperation based on a service agreement (B2B/freelance contract), not an employment contract.
• You will operate as an independent contractor, responsible for delivering agreed services and submitting invoices.

Location

• Open for contractors based in Poland.
