Third Financial and Dunstan Thomas, both part of Nucleus Enterprise, provide market-leading investment platform technology, software solutions, and outsourced operations to wealth managers, private banks, and advisory firms. Together, we deliver a comprehensive ecosystem spanning front-to-back-office capabilities, combining deep operational expertise with robust, scalable technology.

We are seeking an Implementation Consultant to support the successful delivery of pension-related projects and implementation initiatives. Acting as a bridge between customers, business teams, and technical delivery teams, you will combine strong pensions expertise with business analysis and testing capabilities to ensure solutions meet customer requirements and deliver expected outcomes.
This role is ideal for a pensions professional who enjoys exploring pensions software, becoming the expert on investment platforms, gathering and analysing requirements, defining business processes, supporting solution design, executing implementation activities, being the “go-to” person for pensions knowledge, and contributing to testing activities throughout the implementation lifecycle.
Responsibilities

Work closely with our pension experts, product owners, and operations teams to become a subject matter expert in Nucleus Enterprise's investment platforms and software solutions. We are seeking a proactive and inquisitive individual who is keen to develop a deep understanding of platform functionality, user journeys, and operational processes.
This foundational aspect of the role will equip you with the knowledge required to translate client and business requirements into software user stories, assess the impact of change on operational processes, and contribute to the successful execution of testing activities. By developing expertise across multiple product propositions and investment platforms, you will become a trusted point of reference for platform capability, process design, and solution delivery.

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.
