Job 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, and turning a sound method into a model that runs in production.

Scope of Services

Bring expertise in data science and quantitative analysis to w ork 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 partnerfor forecast and pricing models, advising product and business counterparts on problems, solution ideas, and feasibility


• Actively contribute your ideas to technical brainstorming and modelling discussionsas 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

About You

• 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


• 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 relationshipswith your stakeholders, even in a remote setup

Cooperation model

• 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
