Office Manage/ HR Assistant

HR and Office Manager

Location: Bristol – Office-based (with some flexibility)

About Us

We’re a fast-growing UK tech start-up on a mission to change the future of AI compute. Life here is busy, ambitious and collaborative. Things move quickly. We solve problems together. We look after one another and we care about building something meaningful.

If you enjoy helping people do their best work and creating an environment where teams can thrive, you’ll fit right in.

The Role

We’re looking for an experienced HR and Office Manager to take ownership of our people operations and day-to-day office management in Bristol.

This is a hands-on, trusted role at the heart of the business. You’ll work closely with the team and the Head of People, acting as the go-to person for employee support and ensuring the office runs smoothly and professionally.

No two days will be the same. Some days you’ll be onboarding a new starter and making sure their first day feels seamless. Other days you’ll be managing absence reporting, supporting recruitment activity or liaising with suppliers to keep the office running as it should.

You’ll also collaborate with our London-based office manager to ensure consistency across locations.
