HR Project Manager in Milton Keynes

Are you a Project Manager seeking a high-impact opportunity? This is an exciting chance to play a key role in a large-scale HR integration between two industry-leading businesses. Offered as a 12-month fixed-term contract, this role places you at the centre of complex organisational change, where your expertise in HR-focused project delivery will make an immediate and lasting impact.

We are looking for an experienced Project Manager with a strong background in HR, people change, or workforce transformation. Experience with HR systems such as Workday or Zellis would be highly beneficial, as these platforms sit at the heart of the HR workstream. You will lead the coordination and delivery of HR projects, acting as the central point of contact for activities linked to people, culture, processes, and systems.

You will ensure all HR-related initiatives are delivered on time, within scope, and aligned to organisational capability, governance, and resourcing. This role requires strong organisation, stakeholder management, and the ability to translate HR priorities into clear, actionable project plans. Working cross-functionally, you will ensure the HR workstream is well-planned, achievable, and delivered in line with integration milestones using your excellent communication skills to keep stakeholders engaged and informed.

The Role:

• Lead planning and coordination of HR workstream activities across the integration programme.
• Ensure HR projects such as organisational design, policies, recruitment, onboarding, payroll, benefits, learning, and culture initiatives are delivered on time, within scope, and aligned with business requirements.
• Drive consistency and quality to ensure people-related change is embedded effectively into business operations.
• Define HR project scope and objectives, engaging relevant stakeholders (HR, Finance, Legal, Operations, Talent, and IT) to ensure feasibility.
• Ensure resource availability and effective allocation across multiple HR initiatives.
• Develop and maintain detailed project plans, timelines, and RAID logs to monitor and track progress.
• Manage changes to project scope, schedule, and costs using agile techniques and continuous improvement principles.
• Build strong relationships with senior stakeholders, acting as a trusted advisor for the HR workstream.
• Identify, assess, and mitigate HR-related risks to ensure successful delivery.
• Produce clear, accurate project documentation and updates for governance forums.
• Track and report progress against short- and long-term HR integration goals.
• Apply and continue to develop your leadership capabilities to influence decisions and support others through change.
• Develop clear delivery data and documentation using spreadsheets, diagrams, and process maps.

Qualifications

Essential

• Strong understanding of HR processes (e.g., onboarding, payroll, benefits, policies, organisational design).

• Ability to manage multiple priorities in a fast-paced, complex environment.
