The Role

This is an excellent entry point into HR within a fast-paced, scaling tech company. As HR Administrator, you will be the operational engine that keeps the HR function running smoothly, ensuring accurate records, coordinating key processes, supporting employee benefits administration, and providing a reliable, friendly first point of contact for employees and managers.

Reporting to the Director of HR, and working closely with the HR People Partner, you will take clear ownership of the administrative workload that underpins the HR function, from issuing contracts and managing the onboarding process, to maintaining BambooHR and supporting the Go1 learning platform. You will also provide ad hoc support to the wider Operations team as needed.

This role is ideal for someone with 1–2 years of HR or office administration experience, or a recent graduate with a strong interest in building an HR career. There is a clear path to grow into a more senior HR role over time.
