- Help customers design and refine prompting strategies and related AI workflows to unlock the full value of the platform.
- Build and maintain strong, trust-based relationships with customers, acting as their primary technical liaison into product and engineering.
- Gather, synthesise, and communicate customer feedback to drive product improvements and documentation updates.

- Hands-on experience with PostgreSQL, including troubleshooting data workflows.
- Experience in a customer-facing role — you know how to listen, communicate clearly, and build credibility with technical stakeholders.
- Ability to guide customers through prompting, AI workflow design, and related problem-solving.
- Excellent written and verbal communication skills; comfortable bridging customer needs and engineering context.
