Senior HR Advisor

Overview of the role 

Phoenix is a leading UK IT solutions and managed service provider, with a deep specialism in the public sector. We work with organisations across government, healthcare, defence, public safety, education, housing, and the charity sector - helping them modernise with confidence across cloud, data and AI, cyber security, and managed services. 

Through strategic partnerships with the world's leading technology providers - and a trusted place on the major public sector frameworks - our work has a direct impact on the services that millions of people rely on every day. 

Due to continued growth, we are hiring a new Senior HR Advisor who will provide high-quality, commercially focussed HR support across the organisation. 

What will you be doing? 

• Act as the lead advisor on complex employee relations matters, ensuring fair, timely, and legally compliant outcomes 

• Provide expert, commercially focused HR advice to managers across the full employee lifecycle 

• Lead the development, review, and implementation of HR policies, ensuring alignment with legislation and best practice 

• Coach, challenge, and upskill managers through guidance, training sessions, and ER support 

• Represent HR in investigations, hearings, and formal meetings, producing clear, high‑quality documentation 

• Support and contribute to wider HR initiatives, including engagement, change, restructures, and organisational development 

• Partner with the wider People team to deliver consistent, high‑quality HR operations and a positive workplace culture 

Why should you apply? 

At Phoenix, our ambition is to be the UK's leading IT solutions and managed service provider - and we know that only happens because of our people. Culture isn't an afterthought here; it's the thing we work hardest on. 

We're proud to be certified as a Great Place to Work®, and to be recognised on their UK Best Workplaces lists for Women, Wellbeing, and Development. These aren't badges we chase - they're the result of how we genuinely choose to treat each other, and how seriously we take our colleagues' careers, health, and lives outside of work. 

When you join Phoenix, you can expect: 

• A culture built on trust and belonging: set out clearly in our Culture Blueprint, lived day-to-day, and reflected in our consistently strong colleague feedback. 

• Real investment in your development: structured learning pathways, funded industry certifications, mentoring, and the encouragement to stretch into new areas. 

• A workplace that takes wellbeing seriously: from mental health support and flexible working to active employee networks and a leadership team that listens. 

• A commitment to equity and inclusion: where we actively work to make Phoenix a brilliant place to build a career, whoever you are. 

• Work that matters: supporting the public sector organisations that keep the UK running, from government and healthcare to defence, public safety, education, housing, and the charities serving the most vulnerable in our communities. 

• Working with the best of the industry: alongside genuine experts, and with strategic partnerships across the world's leading technology providers, you'll be at the front of the conversations shaping how UK public services modernise. 

We believe in encouraging, supporting, and skilling our people up so that you can be the very best you can be at work - and we'd love you to consider being part of it. 

Take a look at our Culture Blueprint to get a real sense of who we are.

We will be looking for somebody who has experience working in a similar office-based sector and within a similar-sized organisation (250-500 people) in a role that has a broad level of responsibility. 

Key Skills & Experience: 

• CIPD Level 5 qualified, with willingness to work towards CIPD Level 7

• Demonstrated ability to independently manage high‑risk, sensitive, and complex employee relations matters
