What you’ll do

AssessFirst’s client base is growing, so we’re looking for a new Customer Success Manager to manage a portfolio of clients across the International market. In this role, you will ensure an exceptional experience for our clients and partners. Your focus will be twofold: supporting successful implementation and effective use of the platform, and managing the timely resolution of technical support issues.

1. Customer Onboarding, Adoption & Success Management
Lead seamless onboarding and drive early activation, while continuously managing customer health, engagement, and adoption to ensure long-term success and retention.

2. Value Realisation, Renewals & Growth
Translate product usage into measurable business outcomes, reinforce value through strategic guidance and success reviews, and contribute to renewals and revenue growth via retention and expansion.

3. Technical Support & Cross-functional Collaboration
Provide responsive technical support and issue resolution, conduct investigations and improve documentation, while collaborating across teams and advocating for customer needs internally.

How you’ll do it

You will own the full customer lifecycle - from onboarding to renewal (with support from your Account Manager) whilst acting as a trusted advisor and first point of contact for both functional and technical needs. Your role will be focused on ensuring clients are supported from initial training and onboarding, to project roll-out, and achieving their KPIs. You will also provide high-quality customer support, providing fast and helpful resolutions to issues and escalating to the internal teams where necessary.
