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
