AI Engineer, Agent at Eloquent AI

About the role

Eloquent AI is a San Francisco-based YC X25 startup that recently raised a $7.4M seed round led by Foundation Capital to build autonomous AI Operators for financial services. Work directly with co-founder Aldo Lipani, a UCL Machine Learning professor, on cutting-edge multimodal agents that achieve human-level precision in high-stakes regulated environments. Backed by Foundation Capital and Y Combinator (X25), Eloquent AI is already powering major financial institutions, solving up to 96% of cases where traditional chatbots fail. Join a high-growth startup at the seed stage with significant equity upside, building technology that fundamentally changes how millions of people manage their finances. Location: San Francisco, USA.

Responsibilities

• Design and optimize autonomous AI agents that perform actions across CRMs and payment systems, rather than just generating text responses.
• Fine-tune LLMs for accuracy and compliance while implementing RAG and inference optimizations for real-world enterprise applications.
• Collaborate with global engineering and research teams to monitor performance and iterate rapidly on agent capabilities based on customer feedback.

Requirements

• 3+ years of experience in AI engineering or NLP, with strong Python proficiency and hands-on experience using PyTorch or TensorFlow in production.
• Proven track record of working with LLMs, including expertise in prompt engineering, fine-tuning (PEFT), and retrieval-augmented generation (RAG).
• Ability to thrive in a fast-paced startup environment, demonstrating strong problem-solving skills and the capacity to integrate AI with complex cloud infrastructure.
