Job Description

The Implementation Manager will play a key role in bringing new clients onto LifeSight and delivering impactful projects for our existing client base. This is a varied, hands‑on role that combines project delivery, client engagement, and collaboration across teams.

LifeSight, WTW’s DC master trust, represents one of our biggest business growth opportunities in the UK. Our growing team has already quickly gained a foothold in this exciting space, supported by an ambitious marketing and sales plan aiming to disrupt the marketplace and make us stand out against our competitors. Our objective is to become the pre-eminent player in outsourced pensions for large companies and to be a market leader and innovator in the field. We expect LifeSight to become one of the largest UK pension plans in terms of assets under management. We have secured in excess of £25bn of assets under management and 450,000 members with a pipeline which will enable us to grow this exponentially over the coming years.

Reporting to the LifeSight Head of Operations, you’ll be responsible for leading client implementations from start to finish—working with clients and colleagues to agree implementation configurations, overseeing the transition of members into LifeSight, and managing the relationship through the early stabilisation phase before handover to the Client Manager. Where needed, you’ll also support sales meetings and contract discussions to help set up successful delivery.

In addition to new client onboarding, you’ll manage a range of projects for existing clients, such as investment fund changes, regulatory events, membership updates, and process or product improvements. You may also act as the ongoing Client Manager for a small number of clients, working alongside the wider WTW client team to ensure a consistent and high‑quality service.

This role is ideal for someone looking to grow their career in client implementation and project management, with exposure to a broad range of clients, stakeholders, and change initiatives.

This role will occasionally require on‑site visits to our Redhill/Reigate office.

The majority of our colleagues work in a hybrid style, with a mix of remote, in-person and in-office interactions dependent on the needs of the team, role and clients. We understand flexibility is key to supporting an inclusive and diverse workforce and so we encourage requests for all types of flexible working as well as location-based arrangements.

The Role

• Manage client expectations throughout the implementation, clearly setting out required decisions, actions, and what clients can expect from the LifeSight delivery team
• Own the end‑to‑end implementation plan, driving activity to completion in line with agreed timelines
• Act as the primary client liaison during implementation and transition, including escalation of issues and oversight of any related pre‑transition consulting projects
• Work closely with internal workstreams (legal, communications, administration, and asset transition) to align processes and deliver solutions within required timeframes
• Lead the drafting and agreement of the implementation configuration specification, translating client requirements into the LifeSight framework
• Coordinate reporting and communications across the delivery team and key internal stakeholders
• Provide hands‑on client and delivery team support during transition and stabilisation to ensure a high‑quality onboarding experience
• Partner closely with client advisers, particularly on configuration decisions and implementation actions
• Contribute to continuous improvement by identifying and promoting enhancements to implementation processes, documentation, and delivery practices

What you'll bring

• Strong working knowledge of occupational DC pensions, pensions administration, DC investment strategies, and the DC marketplace (ideally within a master trust environment)
• Proven experience leading complex implementation and change projects, including asset transitions
• Excellent project management, risk management, and stakeholder management skills, with the ability to negotiate and operate effectively in a matrix environment
• Track record of building and maintaining strong client and internal relationships across multi‑disciplinary teams
• Collaborative, self‑motivated, and comfortable working with ambiguity; willing to roll up sleeves when needed
• High emotional intelligence with excellent written and verbal communication skills
• Ability to manage a large and diverse workload while delivering high‑quality outcomes
• Broad understanding of the product and operational aspects of a master trust like LifeSight
• Strong problem‑solving skills, with the confidence to develop and challenge ideas to meet client and business needs
• Proficient in Microsoft Excel, Word, PowerPoint, and Project
• Firm commitment to professional excellence and high‑quality service delivery
