dataroles summary, based on the employer's posting.
What you'll do
- Turn commercial requests into clearly bounded projects and answer operational questions from stakeholders
- Convert revenue-management ideas into testable changes, then carry experiments through to production
- Work with teammates and neighboring engineering groups to shape the RMS as a whole
- Improve the reliability, technical condition and observability of the existing system
What you bring
- A master’s or PhD in a quantitative discipline such as operations research, mathematics or another related field
- Strong grounding in demand modeling, dynamic pricing and network revenue management
- Hands-on Python skills, including NumPy, Polars, Pandas and SciPy, plus SQL experience with large datasets
- Clear communication with technical and commercial audiences, alongside sound judgment about project scope and system constraints
Who this fits
This is a hands-on senior role for someone comfortable improving an established production system rather than starting from scratch. You’ll need to balance immediate fixes with longer-term system direction and explain quantitative trade-offs to different audiences. The role is based in Berlin and follows an office-first hybrid model.
From the employer
At Flix, we offer a tech-driven environment where innovation meets real-world impact, with competitive pay, strong growth opportunities, and a culture of collaboration and ownership.
We're looking for a motivated and skilled Senior Data Scientist to join our Team Greenrock – Demand Division.
Our Tech team owns Flix's Revenue Management System (RMS), a production system with a direct commercial impact. We are looking for a colleague who will play an active role in shaping the next generation of the RMS by leveraging their deep expertise in revenue management.
This is a hands-on senior role in a non-greenfield environment: delivering meaningful change requires care, conviction, and patience.
About the Role
- Work closely with commercial stakeholders to translate business requirements into well-scoped projects and respond to operational inquiries.
- Translate revenue management theory and industry best practices into concrete, testable improvements, from idea and experimentation through to production rollout.
- Co-own the evolution of the entire system through regular collaboration and discussions with peers across your team and neighboring engineering teams.
- Contribute to the technical health, reliability, and observability of the existing system.
About You
Education and Revenue Management expertise (must-have)
- Advanced degree (Master’s or PhD) in Operations Research, Mathematics, Statistics, or a related quantitative field
- Solid theoretical foundation in RM: demand modeling, dynamic pricing, and network revenue management.
- Applied experience with RM or pricing tech solutions in transportation, travel, hospitality, retail, or a comparable domain is a big plus.
Engineering and data craft
- Strong hands-on Python (including NumPy, Polars, Pandas, SciPy) and comfort with SQL on large datasets.
- Production-code experience is welcome but not required; what we expect is genuine interest in writing, reviewing, and maintaining code that runs reliably in production.
Soft skills
- Excellent communication: you explain complex quantitative concepts or optimisation trade-offs to technical and non-technical, commercial audiences alike, and you enjoy educating and advocating for sound RM solutions.
- Senior judgment: you scope your own work, balance short-term fixes with long-term direction, and respect the constraints of an existing system.
We recognize that everyone carries a unique set of valuable skills and experiences. If you think you could have an impact even though you don't meet 100% of the requirements, we still encourage you to apply. We want to hear from you!
What We Offer
- Travel perks: 12 free Flix vouchers + 12 discount vouchers for friends & family.
- Work from (M)Anywhere: Depending on your role, work from another location for up to 60 days per year.
- Hybrid work model: We are an office-first company, but we offer flexibility to balance work and life.
- Wellbeing support: Access confidential 1:1 counselling, courses, and stress management for yourself and up to four family members.
- Learning & Development: Take advantage of language classes, training courses, and expert-led sessions to grow your skills.
