Role Overview

As an Implementation Manager at Atominvest, you will own the end-to-end delivery of our platform for some of the world's most sophisticated alternative investment managers, and act as their day-to-day contact and the face of Atominvest throughout. White-glove service is part of our competitive edge — clients trust one person to understand their business, solve their technical problems, and be accountable end-to-end. To do that credibly, you need to be hands-on and technical — as comfortable mapping a client's data model and scoping an API integration as you are running discovery workshops or presenting to a C-suite sponsor.

You will lead complex, multi-stakeholder implementations from first workshop to go-live, designing the implementation plan itself rather than just executing someone else's. Delivery and technical substance are what earn you the trust to be the face of the account — not the reverse. You'll work closely with Sales, Product and Engineering to ensure client outcomes are delivered to the highest standard.

What You'll Be Doing

Own the full client lifecycle: discovery, solution design, configuration, data migration, integrations, UAT, training, go-live, and post-deployment success

Act as the client's single day-to-day point of contact and the face of Atominvest — the credibility to hold that position comes from actually knowing the platform, the data, and the plan in detail

Run structured discovery workshops to translate a client's fund structures, data model, and reporting requirements into a concrete implementation plan and platform configuration

Design and advise on implementation plans — sequencing, dependencies, resourcing, and technical approach — rather than simply executing a pre-set template

Work with Product and Engineering to scope and discuss integrations with client technical teams (APIs, SFTP, data feeds), defining what's feasible and what the client needs to build or provide

Lead structured implementation programmes for enterprise clients, managing complex timelines, dependencies, and senior stakeholder expectations

Analyse client datasets, fund structures, and workflows to design and configure optimal platform solutions

Run executive business reviews with C-level contacts alongside Account Managers, distinct from technical discovery sessions, to align on progress and value delivered

Proactively manage risks and customer health

Partner with Product to manage change and operational risk during feature deployments — coordinating rollouts, communicating impact to clients, and ensuring new functionality lands smoothly within live production environments

Act as the bridge between clients and the product roadmap — gathering structured feedback, influencing prioritisation, and owning delivery of new features to your client base

Deliver consistently high-quality, responsive, white-glove support — treating every client issue with ownership and clear judgment
