• Consulting on architectural decisions, including LLM evaluation, prompt versioning, or how to structure evals for reliability and reproducibility
• Translating real-world usage and customer friction into actionable feedback for our product and engineering teams
• Partnering with sales, support, and engineering to ensure seamless handoffs from pre-sales to post-sales and back
• Contributing to internal runbooks, implementation guides, and technical documentation
