HR Advisor

Build a better future, one job at a time. At Gattaca, our purpose is simple: to provide the skills needed to build a better future, one job at a time. Every person in our business has a part to play in that… including you.

We’re looking for a digitally minded, relationship‑driven HR Advisor who’s confident, organised, commercially sharp, and brilliant at communicating with clarity and intent. Someone who can build trust quickly, challenge constructively, and collaborate effortlessly across a fast‑moving, performance‑driven environment.

What you’ll be doing:

• You’ll be a trusted partner to leaders and teams across the business, providing practical and proactive advice across the full employee lifecycle.
• You’ll lead on employee relations, coach managers, drive wellbeing initiatives, support EDI improvements, and bring a continuous‑improvement mindset to everything you do.
• You’ll be embedded into dedicated business areas, seen as an extension of the leadership team, not an add‑on.
• Alongside the wider People team, you’ll play a key role in shaping an inclusive, high‑performance culture where people feel engaged, supported and set up to succeed.

Key responsibilities:

• First point of contact for HR advice, coaching and ER guidance
• Managing ER cases across conduct, performance, sickness and wellbeing
• Supporting wellbeing initiatives aligned to our People and ESG strategies
• Delivering manager education on people fundamentals
• Producing HR insights and reports using our HRIS, to back up advice
• Supporting engagement activity using our engagement platform
• Driving inclusion by challenging bias and championing our DNA behaviours
• Partnering with leaders to anticipate people needs and provide proactive solutions

Whilst based in our Whiteley office, you have the opportunity to work in our London office, one day a month, as well as the flexibility to work from home up to 2 days a week (whichever suits your needs) once you’re past the onboarding period.

What you’ll bring:

• CIPD Level 5 or equivalent experience
• At least 2 years in a HR Advisor or generalist role
• Strong commercial understanding (ideally gained in a corporate or sales-led environment)
• Confidence to challenge respectfully and coach effectively
• Excellent organisation, attention to detail and written accuracy
• Digitally confident, data‑minded, curious and adaptable
• A genuine commitment to inclusion, wellbeing and continuous improvement
