The Gig

We're looking for a proactive and perceptive Customer Success and Marketing Manager to lead the charge on understanding how our clients feel about the work we deliver. Acting as an independent voice, you'll reach out to client's post-project to gather structured and meaningful feedback, including Net Promoter Score (NPS), and feed this back into the business to improve quality, satisfaction, and retention.

This role sits alongside our Account Management team — working collaboratively to ensure feedback is collected at the right time, with the right context, and turned into insights that drive real change.

What You'll Be Doing

* Client Feedback & Satisfaction Monitoring
*
o Contact clients mid and post project delivery to gather feedback on their experience.
* Administer and track Net Promoter Score (NPS) surveys to measure satisfaction and loyalty.
* Work with Account Managers to determine the optimal timing and approach for gathering feedback, based on project specifics and client relationships.
* Act as an independent voice to help clients share open and honest insights.
* Insight Sharing & Internal Collaboration
*
o Share feedback with delivery teams to celebrate successes and address areas for improvement.
* Collaborate across departments to ensure actionable insights lead to improved client experiences.
* Maintain a feedback loop that supports ongoing service excellence and innovation.
* Content Creation, Recognition & Awards
*
o Collaborate with clients to secure quotes, testimonials, and project highlights for use across social media and marketing materials.
* Develop compelling case studies that tell the story of our most impactful work.
* Identify opportunities for award submissions and work with clients who want to be recognized — crafting thoughtful, high-quality entries that showcase project outcomes, impact, and innovation.
* Liaise with both internal teams and clients to gather data, visuals, and approvals required for award entries.

Success Metrics

* Improved client retention.
* Increase in quality and volume of client feedback, including NPS participation and scores.
* Growth in the number of published case studies and client testimonials.
* Successful award nominations and wins based on submitted work.
* Improved client retention and positive sentiment, measured through surveys and internal feedback.

About You

* Strong interpersonal and communication skills — both written and verbal.
* Comfortable engaging with clients to encourage honest and useful feedback.
* Experience administering or analysing NPS or other satisfaction metrics.
* A collaborative mindset with the ability to understand context and tailor approaches accordingly.
* Strong attention to detail, especially when developing case studies or writing award entries.
