About the Role:

As a Client Success Manager, you are the bridge between ambitious digital strategy and flawless execution. You will drive eCommerce success by acting as a trusted advisor to a portfolio of clients, helping them refine their digital roadmaps and identifying growth opportunities across both monthly retainers and specialized projects.

This is a high-impact role requiring a blend of strategic thinking and rigorous project management. You’ll stay ahead of industry trends to provide "fresh ideas" that improve ROI, while ensuring that internal teams are aligned and tasks are delivered on time and within scope.

Communication: Exceptional written and verbal communication skills; ability to explain complex strategies clearly and professionally.
Analytical Mindset: Comfortable with Google Analytics and using data to drive quarterly strategic reviews and actionable insights.
Technical Literacy: A base-level understanding of design programs, development languages, and the wider digital ecosystem (plugins, social media, email marketing tools).
Project Management: Ability to manage multiple tasks, adhere to time pressures, and maintain high attention to detail.

If you don’t tick every single box but you are an experienced Client Success professional excited about eCommerce and AI‑driven growth, we’d still love to hear from you.

Client Strategy Development: Proactively brainstorm and implement tactical and strategic roadmaps that drive measurable business growth.
