? The Role
As the TSA Data Manager, you'll play a key role in ensuring GTR's Train Services Agreement (TSA) runs like clockwork. You'll take charge of collating, verifying, processing, and publishing performance data-covering availability, cancellations, delays, and service quality-helping GTR deliver efficient, reliable services every single day.
You'll be the go-to expert for accurate performance insights, working hand-in-hand with a dedicated management team and collaborating with partners such as Siemens to keep our Class 700 fleet performing at its best.

• Provide robust data and analysis to support performance improvement targets and ensure GTR receives all income due under the TSA.
• Minimise counterclaims and challenges by delivering transparent, reliable daily performance data.
• Support swift resolution of commercial claims, aiding the wider performance management team at Three Bridges and Hornsey Depots.
• Produce clear and engaging performance reports, metrics, and visualisations.

• Provide administrative and analytical support to the Engineering Contracts Team, including managing purchase orders, documentation, and formal correspondence.

? What You'll Bring
We're looking for someone who thrives on detail and collaboration, with the confidence to turn complex data into clear, actionable insights.
Essential knowledge & experience:

• Strong understanding of the Railway Industry and how partners collaborate.
• Experience managing commercial performance regimes and performance data.
• Familiarity with Railway IT systems (e.g. TRUST, GENIUS/Trent, Web Gemini).
• Experience working with Rolling Stock performance measures (availability, delays, cancellations, service quality).
• Working knowledge of finance systems such as ORACLE.
• Skilled in Microsoft 365 (Excel, Word, PowerPoint, Outlook) with strong data analysis and presentation skills.
• Excellent communicator who can influence and collaborate across all levels.

? Who You Are?
You're detail-driven, analytical, and confident working with high-stakes performance data. You enjoy problem-solving, challenging assumptions, and improving systems and processes. Above all, you're motivated by accuracy, accountability, and teamwork.
? Why Join GTR?

• Play a vital role in the smooth running of one of the UK's largest rail networks.
• Be part of a forward-thinking, data-driven organisation that values innovation and continuous improvement.
• Enjoy opportunities for growth, collaboration, and professional development in a supportive environment.
