Shelf is a company that provides a core infrastructure that enables GenAI to be deployed at scale, helping companies deliver more accurate GenAI answers by eliminating bad data in documents and files before they go into an LLM and create bad answers.
About Shelf There is no AI Strategy without a Data Strategy. Getting GenAI to work is mission critical for most companies but 90% of AI projects haven't deployed. Why? Poor data quality - it is the #1 obstacle companies have in getting GenAI projects into production. Shelf unlocks AI readiness. We provide the core infrastructure that enables GenAI to be deployed at scale. We help companies deliver more accurate GenAI answers by eliminating bad data in documents and files before they go into an LLM and create bad answers. Our mission is to empower humanity with better answers everywhere. Job Description: The Sales Engineer will serve as a forward-deployed technical expert, independently leading proof-of-value engagements with enterprise prospects. This role combines deep technical expertise in data modeling and ontology design with hands-on implementation skills to deliver rapid-cycle pilots that demonstrate Shelf's value and convert to closed deals. This is a unique opportunity to work at the cutting edge of AI and data quality, designing custom data models and configuring reasoning agents to solve complex enterprise challenges. You'll operate with significant autonomy, embedded with prospects during 3-5 day pilots, iterating quickly to prove measurable value. Your ability to understand customer data architectures, design semantic models, and deliver technical solutions will be crucial to our sales success. Reporting to the Field CTO, you'll partner with Account Executives throughout the sales cycle, with primary responsibility during technical evaluation and POV phases. Beyond new customer acquisition, you'll support expansion opportunities within existing accounts, contributing to our land-and-expand growth strategy. You'll work directly alongside Engineering during POVs and collaborate on building reusable templates and best practices.
