About the role

Joju operates across EV charging, commercial solar PV, and operations & maintenance. Joju needs a senior finance leader to take ownership of the finance function, strengthen controls, improve reporting, develop the team and provide commercial challenge to the wider business.

You’ll report directly to the CEO and act as the senior finance lead across the business, partnering with operational leaders. This is a hands-on role – you’ll be close to the detail on management accounts and cashflow, but you’ll also be the person the operational teams turn to when they need financial input on projects, tenders, and commercial decisions.

We’re looking for someone who can combine strong technical accounting with genuine people management, and who isn’t afraid to challenge the business where the numbers don’t stack up.

Improve / Redesign processes, controls, and how data is used to support decisions

Compliance & Audit Oversee VAT returns, CIS, payroll, and statutory reporting

What We’re Looking For Essential Qualified  accountant (ACA / ACCA / CIMA)

Why Joju?

We’re a growing business in a sector that isn’t slowing down. The finance function matters here – it’s not a back-office afterthought. You’ll work directly with the CEO and the operational teams, and you’ll have genuine influence over how the business runs. If you want a role where you can shape things rather than just report on them, this is it.
