• Employ an agile approach, emphasizing swift delivery, responsiveness to feedback, and continuous improvement.

What We’re Looking For:

• Expertise with LLMs: Hands-on experience with state-of-the-art language models like GPT-4o, including safely deploying them in production environments. Familiarity with applications and architectures involving conversational agents, fine-tuning, and Retrieval-Augmented Generation (RAG).

• Search and Recommendations: Proven expertise in building personalized search and recommendation systems, with a deep understanding of information retrieval and natural language processing (NLP) challenges like Named Entity Recognition (NER).

• Engineering Excellence: Strong programming and engineering skills, with the ability to design, build, and maintain scalable AI systems.

• Communication and Collaboration: Clear, effective communication skills, with the ability to translate complex AI concepts into practical, actionable solutions for cross-functional teams.

• Startup Mindset: Experience in fast-paced environments, with the ability to navigate ambiguity, take ownership of projects, and – most importantly – get shit done
