Responsibilities

Business Central and Integrations

Act as system owner for Dynamics 365 Business Central across finance, projects, service, and purchasing

Manage user setup, permission sets, and approval workflows, including quote and purchase approval limits

Monitor and recover job queues, including defect processing and contract and PPM job generation

Maintain and improve the Business Central and Solarvista interface, including defect records and job creation

Build and document APIs, app registrations, and OData endpoints for other systems and for AI development

Manage extensions such as Continia, the Microsoft release cycle, and sandbox testing before production release

Define requirements, test, and accept any development carried out by an external partner

Maintain dimensions, master data, role centres, and Power BI reporting

Microsoft 365, Azure, and IT Support

Administer the Microsoft 365 tenant: Entra ID, Exchange Online, SharePoint, Teams, OneDrive, and Intune

Administer Azure subscriptions and cost management, and manage Microsoft licensing across the estate

Set up and decommission users end to end, including accounts, licences, mailboxes, and Business Central profiles

Provide first and second line support, setup and issue devices, and maintain the IT asset register

Build Power Platform automations where they remove manual administrative effort

Manage the remaining IT and Business Central supplier relationships

Security and Continuity

Own Cyber Essentials certification and the technical controls behind the company cyber insurance

Act as first responder for suspected security incidents, escalating to the specialist supplier for remediation

Own backup, restore testing, and disaster recovery for Microsoft workloads and business data

Govern API and application permissions, so elevated access is granted only on a reviewed and recorded basis

First Three Months

Both incumbent suppliers remain engaged during a three month handover.

Month 1: Document the estate, take over user administration, licensing, and first line support, and establish a single record of IT and systems requests

Month 2: Take over Business Central administration and the Solarvista interface, test backup and restore, and establish the change and release process

Month 3: Hold routine operations independently, agree a forward development plan, and agree revised supplier terms

Essential Experience and Skills

3 to 5 years with Dynamics 365 Business Central in an administration, support, or consulting role

Configuration experience across at least two modules, and practical experience of user setup, permission sets, approval workflows, and job queues

System integration experience: REST APIs, OData, JSON, and OAuth 2.0

Microsoft 365 administration, including Entra ID, Exchange Online, SharePoint, and Intune

Working knowledge of Azure, including subscriptions, app registrations, and cost management

Hands-on IT support: user setup, device builds, and fault diagnosis

Comfortable as the only person in the function, clear about when to elevate, and willing to hold suppliers to account

Documents work properly rather than holding knowledge personally

Right to work in the UK

AL development for Business Central extensions

Experience with Continia or a comparable document capture add-on

Experience integrating a field service or job management platform with an ERP

Power Platform: Power Automate, Power Apps, and Power BI

Cyber Essentials experience, and working knowledge of firewalls and network fault diagnosis

Microsoft certifications such as MB-800, AZ-104, or MS-102

Experience in construction, building services, M&E, or another field service business

Location and Development

Hybrid, based at Edenbridge or London, with occasional travel between the two. Remote working can be discussed, on the understanding that device builds and hands-on support need regular presence where staff are based.

This is a newly created role and the person appointed will define how it operates. We support Microsoft certification and relevant training, and as the company grows towards £30 million turnover by 2030 there is scope to develop into a broader systems lead position.
