We are currently hiring for a People / HR Manager. Join our team today and become part of our innovative and growing organisation!

Location: Home-based with regular travel to Milton Keynes and occasional UK-wide travel

Hours: 40 hours per week, working any 5 out of 7 days

Salary: c.£60k, dependent on experience.

Are you an experienced HR professional who thrives in a fast-paced, hands-on environment? Do you take pride in owning your role, improving systems, and seeing things through to completion? If you’re ready to bring energy, ideas and initiative to a growing business, this could be the perfect opportunity.

We’re looking for a People / HR Manager to lead our operational HR function — someone who’s comfortable working autonomously, builds strong relationships with managers, and brings a proactive, solution-focused mindset to day-to-day challenges. This is a role for a doer, a completer-finisher, and someone who enjoys being at the heart of a fast-paced business.

You’ll be the go-to person for HR queries, ER casework, and policy matters, while also having the space and scope to modernise processes, drive continuous improvement, and implement new systems that make a real difference. This is not a back-office HR role — we need someone who enjoys being visible, credible, and connected to our people across the UK.

Working closely with our Recruitment Manager, you’ll also play a central role in improving onboarding, building a consistent and engaging experience for all new starters.

Key Responsibilities

Day-to-day HR Operations

• Act as the first point of contact for all operational People matters
• Closely manage sickness absence and disciplinary/grievance cases
• Provide proactive guidance to managers and team leaders on employee relations and HR best practice
• Attend and chair formal meetings as needed
• Monitor ongoing HR casework and ensure timely closure

HR Administration Oversight

• Ensure the HR inbox is monitored and managed professionally
• Oversee administrative processing of new starters, leavers, and contractual changes
• Liaise with payroll to ensure accurate monthly reporting and changes

Stakeholder Support and Coaching

• Build effective working relationships with managers across the business
• Coach and support junior managers in people management practices
• Provide on-site support as required (approximately 2 days per week)

Policy, Process and Compliance

• Review and maintain HR policies, processes and documents in line with legislation
• Ensure clear communication of policies and procedures across the business
• Remain up to date with relevant employment legislation and HR best practice

Supporting Growth and Development

• Support the development of People planning to align with business growth
• Identify and implement improvements in HR systems, policies, onboarding and workplace culture
• Collaborate with the Recruitment Manager to design and maintain a consistent and effective onboarding experience
• Lead on HR-related continuous improvement initiatives
• Contribute to building the foundations for a wider HR function as the business evolves

What you’ll bring:

• At least 5 years' experience in a generalist HR role, ideally within a fast-paced operational setting
• Up-to-date knowledge of UK employment law and HR casework
• CIPD Level 5 (or working towards)
• A tech-savvy, systems-minded approach — able to streamline processes and introduce better ways of working
• Able to build credibility and work collaboratively at all levels
• Ability to manage multiple tasks and prioritise effectively
• Professional, empathetic, and commercially aware
• Exceptional communication skills and the ability to coach, challenge, and support managers at all levels
• A calm, professional, and pragmatic style — able to juggle competing demands while keeping things moving
• A continuous improvement mindset, with the drive and initiative to lead projects through to delivery

Ideally, you will also bring:

• Experience in engineering, manufacturing, or technical sectors
• A track record of working independently or in small, growing teams
• Experience working with HR Systems, specifically Breathe

This is a fantastic opportunity for someone who wants autonomy, variety, and the chance to shape how HR is delivered in a growing business. If you’re looking for a role where you can make a tangible impact and help build the future of the People function, we’d love to hear from you.
