Introducing the People Team at Trainline
At Trainline, the People Team is central to supporting the company’s ambition and growth plans.
We are looking for a People Operations Advisor to join our UK People Operations team. Reporting into our UK People Operations Team Manager, you’ll work on all things HR and be responsible for supporting employees across the business and helping to make Trainline a great place to work. You’ll provide high quality support in relation to both core HR processes and ad-hoc projects and quickly become an integral part of the team and wider business.
If you’re successful in your application, you’ll be joining an enthused and high performing team, one which prides itself on providing stellar service at every stage of the employee life cycle, from on-boarding to off-boarding and everything in between.
As a People Operations Advisor at Trainline, you will...
Provide high-quality first-line support to Trainliners by monitoring the People mailbox, ensuring queries relating to HR processes and policies are resolved professionally and within agreed SLAs.
Maintain accurate and high-integrity people data in our HRIS (HiBob), ensuring updates are completed promptly and using a data-first mindset to flag inconsistencies or risks.
Offer clear, consistent guidance to Trainliners and managers on People policies, practices, and processes, escalating more complex cases as needed.
Support the preparation, validation, and processing of the monthly UK payroll, ensuring data accuracy, timely updates, and strong alignment between HiBob, payroll workflows, and Finance.
Assist People Business Partners with cyclical People processes (Absence management, Performance, Salary Review, L&D, Engagement) by preparing data, generating reports, running checks, and helping communicate key actions or deadlines.
Coordinate onboarding activities including pre-boarding support, completion of background checks and Right to Work documentation, and ensuring new starter data is accurate and complete across systems and workflows.
Work closely with Accounts Payable to process People-related invoices and POs accurately, supporting efficient financial administration.
Develop, maintain, and interpret weekly/monthly People reports, using tools such as HiBob, Excel/Sheets, or BI dashboards to identify data issues, trends, or insights that help the team drive better decision-making.
Support the review, improvement, and implementation of People policies, processes, and templates, ensuring they are up to date, user-friendly, and aligned with a tech-first, self-service culture.
Contribute to People team projects and continuous improvement initiatives, bringing a curiosity for technology and process optimisation—e.g., testing new HRIS features, documenting workflows, supporting change rollout, or helping improve the employee experience through digital solutions.
Adopt a tech-forward approach in daily work by championing the use of HR systems, automation, and digital tools to enhance efficiency and accuracy across People Ops processes.
Based on the sensitive nature of the role, it’s important that you bring the appropriate degree of discretion and empathy in the way you operate. To this end, you’ll be responsible for identifying escalation points and making sure that any issues are managed appropriately and are dealt with efficiently. Furthermore, being heavily involved in all our HR processes means that you’ll be ideally placed to contribute towards the development of new solutions that further enhance the quality, competence and effectiveness of our current offering.
We'd love to hear from you if you have...
