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.

As a People Operations Advisor at Trainline, you will:

• Provide high-quality first-line support to Trainliners and resolving HR process and policy queries professionally and within agreed SLAs.
• Produce and maintain accurate people data, ensuring high data integrity in our HRIS (HiBob) and that updates are completed promptly.
• Apply a data-literate, analytical mindset to validate information and produce reports that support People Ops delivery and decision-making.
• Deliver change alongside day-to-day People services by contributing to People Ops projects such as system enhancements, process redesign, and embedding AI-enabled solutions, while balancing inbox SLAs, operational deadlines, and project work through effective planning and prioritisation to ensure reliable delivery.
• Support the preparation, validation, and processing of the monthly UK payroll, ensuring accurate and timely data inputs and alignment between HiBob and payroll workflows.
• Manage employee lifecycle administration, including pre-boarding, contracts, background checks, Right to Work documentation, and visa sponsorship, ensuring employee data is accurate across systems and workflows.
• Process People-related invoices and purchase orders accurately, partnering with accounts payable and supporting effective financial administration.
• Support and manage the improvement, implementation, and documentation of People policies, processes, and templates, ensuring they remain up to date, user-friendly, and aligned with a tech-first, self-service culture.

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.

You bring a solid foundation in People Operations and are motivated to continue learning and developing in a fast-moving, tech-enabled environment. Working understanding of HR best practices, employment law, and core HR processes, with the ability and curiosity to stay up to date with regulatory change.

Experience supporting payroll administration, including maintaining payroll data, running checks, and a working understanding of UK tax, NI, and statutory requirements.

Comfortable working with HR systems (ideally HiBob or similar HRIS), with a genuine interest in using technology to improve People processes.

Data-literate, with the ability to produce, interpret, and validate reports, ensure data quality, and use insights to support People Partners and business needs. Exposure to process and ways-of-working improvement, such as documenting workflows, testing system enhancements, refining templates, or supporting change implementation.

Strong attention to detail, particularly when handling people data, contracts, payroll inputs, or employee records.

Clear and professional verbal and written communication skills, with the ability to explain policies and processes confidently.

Strong organisational and time-management skills, able to manage competing priorities, balance BAU and project work, and work to agreed SLAs.

Confident using Microsoft Office or Google Workspace, particularly Excel / Sheets for data handling and reporting.

A self-starter with a helpful, people-orientated demeanour and a high degree of integrity and confidentiality, someone itching to expand upon their HR and payroll experience. An HR qualification isn't necessary - as long as you can demonstrate your interest in HR and show a comprehensive understanding of HR processes and policies, we'll provide you with the necessary professional development to make you an HR superhero.

This is a fantastic opportunity for someone who is passionate about HR, keen to work in a fast-moving, forward-thinking technology business, and looking to develop their career. Enjoy fantastic perks like private healthcare & dental insurance, a generous work from abroad policy, 2-for-1 share purchase plans, an EV Scheme to further reduce carbon emissions, extra festive time off, and excellent family-friendly benefits. We prioritise career growth with clear career paths, transparent pay bands, personal learning budgets, and regular learning days. We're operating a hybrid model and ask that Trainliners work from the office a minimum of 60% of their time over a 12-week period. We also have a 28-day Work from Abroad policy.
