Senior People Manager

Obesity has become a global epidemic; in the UK, we spend £9 billion a year alone on diseases like type 2 diabetes (that’s 10% of the NHS budget). What’s shocking is most of this is preventable – through sustained lifestyle and habit change. Enter Second Nature. We’re here to help people take control of their health. By bringing together the latest behavioural science, psychology, technology, and the talents of our incredible team, our mission is to eradicate the global epidemic of chronic lifestyle diseases once and for all. Our habit-change programme – delivered digitally through mobile and web apps – helps people to transform their lifestyle, lose weight, and ultimately reduce their risk for serious conditions such as type 2 diabetes and heart disease.

We’ve positively changed the lives of over 250,000 people. We’re rated 'Excellent' by over 7k of our members on Trustpilot. We’re growing extremely quickly & are now a profitable business. We’re one of the few consumer health brands that are commissioned by the NHS and leading health insurer, Vitality Health. We’re a leading B2C provider of GLP-1 medication-assisted weight loss programmes, and 1 of 5 NICE-approved providers to deliver these services within the NHS in the future. Our team members stay with us for an average of 4.3 years.

• Spot people-related compliance or data risks early and deal with them proactively, escalating where needed.
• Support teams and leaders through change, helping bring clarity, structure, and better ways of working as the business grows.
