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
