Help some of the world’s largest school groups get more value from the technology at the heart of their operations. As Principal Account Manager, you will own a small portfolio of iSAMS’s most strategic customers, protect and grow those relationships, and turn complex needs into clear commercial opportunities.

Why This Role MattersiSAMS is a management information system (MIS) for independent and international schools. A school MIS brings essential activities such as admissions, timetabling, assessment, reporting, fees and parent communication together on one platform. iSAMS is part of IRIS Software Group, a leading business software and services provider trusted by more than 100,000 customers across 135 countries.

Our largest customers are international, multi-school groups, often backed by investment firms and growing through acquisition. Their structures, stakeholders and priorities can vary widely. This role gives them one senior commercial partner who can bring clarity, coordinate the right expertise and help each group realise more value from iSAMS.About the Team You'll Join You will join the iSAMS Account Management team within IRIS Education and report to the Sales Manager.

You will manage 4–6 strategic school-group accounts across the UK and international markets, working closely with colleagues in product, implementation, support, training, finance and legal.

This is an expansion role, not a high-volume new-business position. Your focus will be existing customers: understanding their goals, strengthening executive relationships and identifying opportunities to add schools, modules and professional services. Professional services means tailored expert support, such as consultancy, solution design, implementation or training.

What You'll Be Doing Own senior relationships across each customer, from group executives to regional and school leaders.

Map how each group is structured, including who makes, signs off and influences decisions.

Lead executive business reviews that demonstrate the value iSAMS delivers across the group.

Negotiate framework agreements, renewals and contract changes, including pricing and multi-year terms.

Protect revenue by identifying risk early, particularly when customers restructure, sell schools or consolidate suppliers.

Grow accounts by bringing newly acquired schools onto iSAMS and expanding the products and services each group uses.

Maintain clear account plans, sales opportunities, and forecasts for every customer.

Coordinate internal specialists and represent customer priorities in product and commercial discussions.

What We're Looking For You are a senior strategic account leader who has managed large, complex national or international customers. Education experience is not essential. We are more interested in your ability to navigate many stakeholders, lead high-value commercial conversations, and grow established customer relationships.

Extensive senior account management experience, with a strong track record in complex enterprise customers with multiple sites and significant revenue.

Experience negotiating high-value, multi-year contracts and renewals with senior buyers and procurement teams.

Evidence of retaining and expanding existing accounts, rather than focusing only on winning new customers.
