About Mimo
Mimo is an AI-native platform for accounting firms. We automate the recurring work inside the monthly close, from chasing client documents and reconciling transactions to posting adjustments and reviewing VAT before it is filed, so accountants spend their time on judgement instead of admin.
Accounting is being rebuilt around AI right now. We intend to be the ones who rebuild it, and to help the firms that get there first do the best work of their careers. We are a team of 35 across Stockholm and London, backed by top European investors including Northzone and Project A, growing rapidly across the UK's top 10-250 firms, with new markets next.
The role
An AI agent posting adjustments is only as good as the accounting judgement behind it. Someone has to decide what correct looks like, then hold the product to it.
We're now looking for someone who has done this work in practice to bring that judgement inside the product. You'll be the person our engineers ask when they need to know how a prepayment should be treated, whether a coding suggestion holds up, and where the standards leave room for interpretation. It's a chance to use everything you know about accounting to build something that changes how the work is done, rather than doing it by hand one more month.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
