A little about us  
We’re the Nucleus Financial Platforms group and we help make retirement more rewarding.  

People come first - whether it’s our colleagues, or the advisers and customers we support, we know that working in partnership and collaboration leads to the best outcomes. Together, we’ve shaped the platform to how it is today. We work hard, and we celebrate hard too.  

Our ambition is to create a platform with a difference, putting the customer centre stage meant tearing up the rule book and starting from scratch. We’ve come a long way since then, but our mission remains just as focused. That’s why our culture, values, and social responsibility are things we keep at the top of our agenda – because we know they matter and have a big impact.  

Our culture is one of the many things that sets us apart from the pack. We want to have an environment where our people feel that they can make a real difference, know they’ll be rewarded for their efforts and more importantly, enjoy themselves at work.  

Inclusion and diversity at Nucleus  
As with most things in life, who cares, wins. We really care about inclusion.  

For us it’s not a tick box exercise; inclusion and diversity are embedded in our culture and everything we do. It’s a commercial imperative. It isn’t about being PC. It’s about being future-relevant and durable. We owe it to ourselves and the industry to ensure we are playing our part in creating a fair, balanced and transparent financial services sector.  

More diversity means broader experience, a wider set of perspectives and a better collective ability to problem-solve. And it means being more representative of customer groups, which supports areas such as product development.  

At Nucleus, we offer a generous blend of benefits for the things that really matter to our people, including a non-contributory pension, bonus, enhanced parental leave, paid time off for emergencies, health and wellbeing initiatives and flexible working options.
