Executive Assistant to the CEO & Chief Events Officer

Salary: GBP 42,000–45,000

Workplace: on_site

Department: HR & Administration

Description

About Climate Action

Climate Action was founded in 2007 and works at the intersection of climate policy, innovation and finance. We bring together a global community of 140,000 members and an ecosystem of over 1,000 partners, UN agencies and private sector organisations through a number of high-impact hybrid and digital events each year, alongside more focused roundtables.

We are a commercial business with a clear mission: to drive meaningful climate progress through the events and partnerships we convene.

The Role

Join a rapidly growing, mission-led company, making a positive impact on our planet.

This is a hands-on, varied role at the heart of a growing team with people who work hard, deliver, and don't take themselves too seriously along the way.

You will split your time supporting our CEO and our Chief Events Officer, while also acting as the central point of support for the wider team, covering everything from diary management and event operations to HR administration, IT coordination and keeping the office running smoothly.

It's a genuinely broad role, and a good fit for someone with EA/PA experience within a private sector SME, who enjoys variety, takes ownership without needing to be asked twice, and wants exposure across HR, systems and events rather than a narrow admin brief.
