Exciting Career Opportunity: People / HR Manager
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:
Essential Skills & Experience
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:
Desirable Skills & Experience
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
Why join us?
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.
