- Travel to client sites as required for onsite engagements; manage remaining client relationships remotely

- Communicate financial results and insights clearly to non-financial stakeholders

Candidate Profile The ideal candidate is a hands-on, detail-oriented accounting qualified who thrives on variety and can move seamlessly between clients and industries.
