Senior Management Accountant

LMJ Group is establishing a specialist Management Accounting and Finance Outsourcing team — a dedicated division focused on delivering high-quality, outsourced finance functions to businesses that need more than compliance. More insight. More strategy. More control over their numbers.

This is a full-time, on‑site role based at either our Luton or Kettering office. The right candidate will not only lead client delivery within this division but will play a central role in shaping it — building the team, defining the service offering, and growing into a Practice Manager position as the division scales.

• Development of KPI frameworks and performance dashboards aligned to client goals

• Act as the outsourced Finance Manager for a portfolio of clients — providing the insight and strategic support of an in‑house finance team, delivered externally
• Build deep, trusted relationships with business owners and senior management, translating financial data into actionable commercial decisions
• Identify and communicate financial risks, opportunities, and strategic recommendations proactively
• Support clients through growth, restructuring, fundraising, and exit planning from a financial perspective

• Take ownership of the management accounting portfolio
• Supervise, mentor, and develop junior members of the management accounting team as the division grows
• Contribute to the design and standardisation of service delivery processes, templates, and reporting frameworks

• Deep, hands‑on expertise in management accounts preparation—including budgeting, forecasting, variance analysis, and board reporting
• Proven experience acting as an outsourced finance function or finance business partner for multiple clients simultaneously
• Strong technical grounding in year‑end accounts, corporation tax, and VAT — to support the wider client relationship
• Commercially minded — able to interpret numbers, identify trends, and translate financial insight into strategic advice
• Confident, credible communicator capable of presenting financial data to non‑finance business owners at board level
• Proficiency with Xero, Quick Books, Sage, Fathom or similar cloud accounting platforms
• Exposure to a diverse client portfolio across multiple industries and business sizes
• Familiarity with Making Tax Digital (MTD) and its implications for management reporting
• Interest in business development and a genuine appetite for growing a service line from the ground up

• Competitive salary, reviewed in line with the division’s growth and your contribution to it
• A collaborative, ambitious practice environment with strong and accessible Director support
