Accounting, insight and advisory assistant manager

Make an Impact at RSM UK

You will be a key member of the growing Business Performance & Insights (BPI) national team, primarily supporting privately owned businesses across the Northern region. As an Assistant Manager, you will support Managers and the wider team in delivering a high-quality, insight-led service to a portfolio of SME clients. This includes overseeing core finance processes such as bookkeeping, management accounts, and VAT compliance, ensuring outputs are accurate, timely, and aligned to client needs. You will also play a key role in translating financial data into meaningful insights, helping clients understand performance, strengthen decision-making, and drive improved business outcomes, moving beyond compliance to a more value-driven, forward-looking service.

The fast growth of the department will create opportunities to develop further skill sets including business development and coaching of junior staff. It will also present an opportunity to expand your internal network and work with a variety of colleagues and service lines across the UK, as well as supporting your local office. A strong understanding of UK GAAP accounting principles is essential.

You’ll make an impact by:

• Deliver a high-quality, client-focused service by supporting managers and managing a portfolio of clients, including project delivery, client care, and WIP/billing.
• Build and maintain strong client relationships, acting as a key point of contact and identifying opportunities to cross-sell additional services.
• Manage assignments effectively, considering profitability, working within budgets, and communicating issues with proposed solutions.
• Lead and supervise engagements when required, including mentoring, training, and providing feedback to junior team members.
• Maintain and develop technical expertise, remain flexible to travel as needed, and respond to client needs with specialist knowledge and continuous learning.
