AI Engineer, Multimodal LLMs

Builds and optimizes multimodal LLM-based AI agents for enterprise conversations, integrating with systems via APIs and automating high-stakes workflows. Requires 3+ years in AI engineering, Python/PyTorch proficiency, and experience with LLMs or vision models.

About the job

Responsibilities

  • Build, deploy, and optimize AI agents that engage in enterprise-grade conversations.
  • Design & develop next-gen multimodal LLM architectures (LLMs, speech, vision, reinforcement learning).
  • Explore optimal trade-offs between model quality and efficiency when translating research into practical solutions.
  • Refine training paradigms for real-world applications.
  • Integrate AI agents with enterprise systems via APIs, databases, and automation tools.
  • Experiment rapidly to improve AI-driven interactions, response quality, and automation capabilities.
  • Collaborate with cross-functional teams (engineering, research, and product) to shape Eloquent AI’s roadmap.
  • Monitor and improve agents’ performance via user simulations and evaluations.

Requirements

  • 3+ years of experience in software development, AI engineering, or NLP in a production environment.
  • Strong proficiency in Python, with experience in frameworks like PyTorch and TensorFlow.
  • Experience working with LLMs or large computer vision models, or generative AI models, including fine-tuning and inference optimization.
  • Familiarity with APIs, cloud infrastructure (AWS, GCP, or Azure), and enterprise integrations.
  • Ability to prototype, experiment, and iterate quickly to improve AI agents.
  • Strong problem-solving skills and the ability to work closely with customers to refine AI solutions.
  • Solid mathematical foundation of machine learning and deep learning techniques.

Nice-to-Haves

  • Experience with prompt engineering, parameter-efficient fine-tuning (PEFT), retrieval-augmented generation (RAG), reinforcement learning for LLMs.
  • Published AI research in top tier AI conferences like: NeurIPS, ACL, SIGIR, ICML and ICLR.
  • Contributed to open-source NLP projects.
  • Worked in a fast-paced startup environment and thrive in rapid iteration cycles.
