About Kamma

Kamma exists to simplify one of the most complex and risky aspects of the housing market, making it clear, accurate, and easy to manage. Property licensing changes frequently, mistakes are costly. We help customers stay compliant without stress, avoid major fines and turn compliance from a cost into a commercial advantage, while supporting higher standards in rental homes across the UK.

Our platform has been rebuilt with fast, adaptable technology that allows us to launch new products quickly and respond to regulatory change. With enforcement rising and rent repayment orders set to double, demand for our solutions is accelerating. We already work with major names, including Foxtons, JLL, Knight Frank, Chestertons, Leaders Romans Group and Spicerhaart.

We are an AI-native company, always striving to find AI-first solutions. We train team members in new and evolving AI tools. We will work together to automate as many repetitive tasks as possible, allowing you to focus your time on the tasks that add the most value.

This is a great time to join. The foundations are strong, momentum is clear, and we are scaling towards Series B revenue levels. You will join a curious, ambitious team motivated by solving problems with pace. Our culture rewards ownership, clarity of thinking and getting things done.

The Opportunity

Property licensing risk is increasing fast, and as we scale our platform and customer base, Customer Success becomes critical to retention, expansion and trust. We are hiring a Customer Success Manager to join our small but growing Customer Success team. You will be responsible for delivering proactive Customer Success for our mid-sized and Enterprise customers, which is central to retaining and expanding revenue over the next 12 months as we scale towards Series B.

This is a new role and a new function at Kamma, with a significant opportunity to shape how we deliver world-class service while segmenting our approach by customer value. Your work will directly influence how we support enterprise customers through high-touch relationships, while enabling excellent, scalable and increasingly self-serve experiences for SMB clients.

If you enjoy owning complex customer relationships, driving commercial growth and helping to build scalable systems that allow teams to focus where they add the most value, this role is for you.

Success in this role is defined by three outcomes:

• Becoming a subject matter expert: on the regulatory complexities around property licensing to add the maximum amount of value to customers.
• Operational Excellence: Ensuring successful technical integration for mid-sized and Enterprise customers, fast resolution of complex product queries, and reliable service across all segments.
• Retention & Growth: Owning the full client lifecycle from initial setup through renewal, driving commercial expansion and account stability, with variable compensation linked directly to expansion and upsell outcomes.

What You Will Do

The hands-on work you do covers the full client journey:

• Own Client Relationships & Service Delivery: Lead high-touch account management for mid-sized and enterprise customers, while playing a key role in shaping how we scale support for SMBs.
• Onboarding: Lead and execute technical and operational onboarding for mid-sized and enterprise customers, including API integration, setting up the customer for long-term success with Kamma.
• Drive Commercial Expansion: Identify, qualify, and close upsell and cross-sell opportunities within your customer portfolio.
• Contribute to Scaling: Work closely with the Head of Customer Success, providing practical, real-world feedback on workflows.

What You Bring

• Experience: 5+ years in Customer Success or similar client-facing roles within SaaS or PropTech, with experience owning relationships for mid-sized or Enterprise customers.
• Proven Track Record: Demonstrated expertise in managing complex client programmes and closing revenue opportunities (upsell and cross-sell).
• Technical Acumen: Comfortable speaking about API integrations, data flows, and technical solutions with both product teams and client stakeholders.
• Environment: Comfortable in an early-stage environment with evolving processes, and motivated by the opportunity to help define those processes from scratch.
• Tech Stack: Tech savvy and AI curious, comfortable learning and using modern tools and CRM systems.
