You will be responsible for managing a portfolio of accounts, ensuring they are effectively utilizing the Siteimprove platform to improve their digital performance. This involves regular check-ins, performance reviews, and technical guidance.

You will work closely with internal teams to advocate for your clients. When a client encounters a bug or requests a feature, you act as their voice within Siteimprove. This requires you to be a subject matter expert on the platform, capable of translating customer feedback into actionable insights for the Product team.

Q: Is the role highly technical? A: Yes, it is a "technical" customer success role. You don't need to be a software developer, but you must be comfortable reading code, understanding web architecture, and troubleshooting technical errors.

Q: What differentiates a successful candidate? A: Successful candidates are those who demonstrate a high level of empathy for the customer while remaining technically rigorous. They show they can handle ambiguity and are proactive in their communication.

• Prepare Questions: Always have insightful questions ready for the interviewer. Ask about the team's biggest challenge, how they measure success, or the company’s roadmap for the coming year.
