We are committed to helping innovative companies thrive by delivering top-tier talent solutions. With deep expertise in recruiting for tech, marketing, and other critical roles, we connect ambitious companies with the perfect talent to accelerate growth. Founded by experienced entrepreneurs, we know that the right hire makes all the difference.
On behalf of our client, we are recruiting for a Principal AI Engineer
The client is a tech-driven expert network and primary research platform that helps consulting and private equity firms discover the knowledge they need to make better decisions. The platform connects clients with industry experts, curates knowledge at scale, and unlocks insights hidden across vast amounts of structured and unstructured information.
You’ll shape how AI systems, large language models, and intelligent retrieval experiences power discovery across our platform. This is a highly strategic engineering role focused on building production-grade AI capabilities that combine LLMs, semantic understanding, recommendation systems, and modern data infrastructure to deliver exceptional user experiences.
You’ll work at the intersection of applied AI, product strategy, and platform architecture - helping define how AI becomes a core capability across the business.
