Senior Business Applications & Systems Integration Lead Full Time

Senior Business Applications & Systems Integration Lead

Microsoft Platform (Power Platform/Azure)
Permanent

Warrington (Hybrid – 2 days on-site)
£75,000 – £95,000 depending on experience

Harvey Nash is proud to be partnered with a fast-growing, people-led construction business that is making a deliberate investment in its internal systems as part of its next phase of growth. Technology is viewed as a core operational enabler – not a side project – and the business is moving away from spreadsheet-heavy processes and disconnected tools towards a joined-up Microsoft platform that genuinely supports how teams work on the ground.

This is a practical, operational environment where systems need to work for real workflows, with real consequences. The organisation is seeking a senior, hands-on technical leader to take full ownership of its internal applications and systems integration landscape, and to shape the long-term digital roadmap.

This is a heavyweight opportunity offering genuine ownership, autonomy and influence.

Why this role exists

The business is investing in a foundational internal systems platform to support continued growth and operational scale.

This role exists to own that platform end-to-end. You will begin by delivering a bespoke internal application (already scoped and prototyped), before moving into defining and delivering a longer-term digital and systems integration roadmap across the organisation.

This is not a delivery-only role, a support role, or a short-term project. It is a hands-on technical leadership position with long-term responsibility and trust.

The mission

As the Senior Business Applications & Systems Integration Lead you will:

• Design, build and own core internal business applications
• Integrate business systems into a coherent, Microsoft-based platform
• Act as the technical authority for how systems are designed, built and evolved
• Embed yourself in the business and shape how technology supports day-to-day operations

This role suits someone who still enjoys being technically hands-on, but wants real ownership, influence and long-term impact.

What you’ll be doing

Phase 1: Core Application Delivery

• Build a bespoke internal application supporting labour orders, approvals and CIS processes
• Translate operational workflows into robust, maintainable systems
• Own architecture, data models, permissions and long-term design decisions
• Deliver something that scales – not a short-term prototype

Phase 2: Digital Roadmap & Integration

• Define and lead a joined-up systems integration strategy
• Design APIs, data flows and automations to reduce manual effort and spreadsheets
• Influence which systems are integrated, replaced or rationalised
• Deliver dashboards and reporting underpinned by reliable data

Phase 3: Microsoft platform ownership

Take ownership of:

• Power Apps, Power Automate, Power BI
• Azure (Functions, Logic Apps, SQL, identity, storage)
• Microsoft 365 integrations (SharePoint, Teams, security)
• Set standards for architecture, documentation and governance
• Act as the trusted technical voice for senior stakeholders

What we’re looking for –

The Senior Business Applications & Systems Integration Lead must have:

• Proven experience designing and building custom business applications
• Strong experience integrating multiple systems via APIs and data flows
• Deep, hands-on experience across the Microsoft ecosystem (Power Platform & Azure)
• Senior-level judgement – including knowing what not to build
• Confidence owning systems independently and standing by technical decisions
• Ability to explain complex technical choices to non-technical stakeholders
• Industry background is not important – judgement, ownership and capability are.

Why this role stands out

• Greenfield build followed by genuine long-term evolution
• Whole-system ownership, not feature-level delivery
• Microsoft-first strategy with freedom to design properly
• Direct access to senior decision-makers
• Low red tape, high autonomy
• Clear opportunity to progress into more senior technology leadership as the business continues to grow
