• Design and iterate on prompts to improve model output and user experience

• Collaborate closely with other engineers to ensure AI features are reliable, performant, and scalable
• Balance experimentation with impact: ship quickly while focusing on user value
• Stay current with advances in LLMs, prompt frameworks, and developer tools - and bring those insights into our roadmap

Requirements

• Strong backend development skills with TypeScript, Node.js, and API design
• 5+ years of experience building web-based products, ideally in B2B SaaS startups
• Proven track record shipping AI-powered features in production with LLM APIs (OpenAI, Anthropic, etc.) and understanding of how to translate machine intelligence into user value
• Hands-on experience with prompt engineering, embedding models, and vector stores
• A user-focused mindset: you care about delivering features that solve real problems
• A bias for shipping and learning - fast iteration is second nature to you
