Are you passionate about turning complex data into meaningful insight that drives real-world outcomes?
At GTR, we're looking for an ambitious and forward-thinking Data Scientist to help us unlock the power of data, machine learning and advanced analytics across one of the UK's largest train operating companies.
This is a unique opportunity to play a key role in establishing GTR's first in-house machine learning capability, helping us better understand future risks, opportunities and operational outcomes. You'll work at the heart of our Data & AI function, developing predictive models that support smarter decision making, improve performance and create tangible value for our customers and business.
About The Role
As a Data Scientist in the Central Data & AI function, you will use advanced analytics, statistical modelling and machine learning techniques to extract forward-looking insights from large and complex datasets across multiple business domains.
- Working closely with operational and business stakeholders, you'll help define business problems, test hypotheses and develop predictive and prescriptive models that influence decision making across commercial, operational and safety functions.
- This role offers the opportunity to work within a modern enterprise data environment, leveraging over 40 DataHub products that support more than 2,000 active users. As GTR continues to expand its data and AI capabilities, you'll play an important role in shaping standards, approaches and best practices for data science across the organisation.
What You'll Be Doing
- Developing predictive and prescriptive models using curated DataHub datasets.
- Applying statistical and machine learning techniques to identify trends, risks and future outcomes.
- Working with stakeholders to frame business challenges, define hypotheses and design effective interventions.
- Translating complex analytical findings into clear, actionable insights for technical and non-technical audiences.
- Explaining model assumptions, limitations and risks to support informed decision making.
- Collaborating with Data Engineers to develop data models that support analytical and machine learning use cases.
- Monitoring, evaluating and improving model performance as business conditions evolve.
- Contributing to the development of data science standards, governance and best practice across GTR.
- Supporting the responsible adoption of AI and advanced analytics within an enterprise environment.
