Vectara is a retrieval augmented generation (RAG) as a service platform. We have a ton of IP already: an embedding model that outperforms Cohere and OpenAI, a reranking model that does similarly, a generative model that outperforms GPT 4 for RAG, a prompt engine that can provide citations and markdown/HTML links in RAG use cases, a leading hallucination detection model, well as our own internal high-performance vector/hybrid database. We just raised $25 million in series A and we're hiring a number of roles.

I personally lead product and before Vectara led product management teams at Kong and Elasticsearch at Elastic and am looking for a technically minded product manager with a few years experience in B2B. Location is pretty flexible for the role, but I'd prefer someone in the US to help increase our timezone coverage for US-based deals and working with our many US (mostly west coast) colleagues. I'm based in Berlin now after having been in SF for the past ~15 years.

All positions are at https://vectara.com/careers/#job-listings, but if you're a PM and interested in developer-focused GenAI, you can reach me at shane at [our domain, above]
