At TTC, we are Enriching lives by connecting people and places. For over 100 years, we’ve been bringing the world closer together by crafting journeys that create lasting memories, lifelong friendships and meaningful cultural connections. Across more than 70 countries and our award-winning brands, we design and deliver travel experiences that go beyond sightseeing - they change perspectives.
Behind every unforgettable journey is a passionate team making it happen. That’s where you come in.
Our Values
Five shared commitments shape how we work, and how we will work with you:
- Value Every Voice. We put people first.
- Act with Integrity. We do what is right.
- Explore Beyond Boundaries. We are driven by curiosity.
- Own the Outcome. We take responsibility for our decisions.
- Succeed Together. We have each other's backs.
The Role
This is a role for someone who wants their models used, not admired. You will solve complex customer and commercial problems through advanced analytics, experimentation and machine learning, working with rich customer, booking, behavioural, marketing and digital data.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
The problem space is broad: segmentation, propensity, personalisation, customer value, retention, forecasting and commercial optimisation. Alongside hands-on work, you will shape analytical methodology, mentor other data scientists and help our most valuable models move from experiment into decisions that change what the business does. The data is rich, the questions are real and the appetite for answers is genuine.
What Will You Do?
- Lead complex data science initiatives from problem definition through modelling, validation and implementation.
- Build predictive and machine learning solutions across priority customer and commercial use cases.
- Apply advanced statistical techniques to uncover behaviour, patterns and commercial opportunity.
- Design rigorous experiments and measurement approaches that reveal genuine incremental impact.
- Set best practice in feature engineering, validation, reproducibility and model evaluation.
- Work with Data Engineering to productionise high-value analytical solutions.
- Guide model monitoring, drift management and ongoing performance.
- Turn sophisticated analysis into clear recommendations for senior decision-makers.
- Mentor data scientists and provide technical leadership across the team.
- Contribute to data science strategy, standards, governance and responsible AI practice.
