Overview

At Calimala.ai, we are redefining the way companies hire top AI talent through our innovative AI-driven hiring platform and expert recruitment services. Our client, a tech startup based in the UAE is seeking an experienced AI Engineer – LLM & Agentic Frameworks to lead the development and integration of advanced language models.  The ideal candidate has hands-on experience working with both closed-source LLMs (e.g., ChatGPT) and open-source LLMs (e.g., Llama, DeepSeek), and understands how to architect, train, and fine-tune these models to meet diverse business needs. You should be able to determine the best approach—third-party APIs versus in-house hosting—and design systems where multiple LLM outputs can seamlessly interact to solve complex tasks, similar to frameworks like Goose.

If you are passionate about generative AI, keep track of the latest innovations, and know how to transform those insights into real-world products, we'd love to hear from you.

Key Responsibilities

LLM Development & Integration

  • Evaluate and integrate closed-source LLM APIs (e.g., ChatGPT) as well as deploy open-source LLMs (e.g., Llama, DeepSeek) in production environments.
  • Determine when to use hosted APIs versus self-managed models for cost, scalability, and performance considerations.

Agentic Frameworks & Architecture

  • Develop and maintain agentic frameworks in which model outputs feed into subsequent prompts or workflows (e.g., Goose-like systems).
  • Ensure robust pipeline orchestration where different AI components can interact efficiently and effectively.

Model Training & Fine-Tuning

  • Perform fine-tuning or training on open frameworks, optimizing LLMs for specific tasks or datasets.
  • Define criteria to decide when and how to fine-tune, balancing performance gains with resource constraints.

Scalability & Performance

  • Architect scalable and fault-tolerant solutions for high-load environments, including containerization and microservices.
  • Collaborate with DevOps to set up CI/CD pipelines, load testing, and performance monitoring.

Innovation & Best Practices

  • Stay updated on cutting-edge research and best practices in the generative AI domain, and identify how new developments can be integrated into existing products.
  • Document processes, create internal knowledge repositories, and mentor junior engineers on AI/ML best practices.

Collaboration & Product Integration

  • Work closely with Product, Data, and Engineering teams to align AI solutions with overall product goals.
  • Communicate complex technical concepts to both technical and non-technical stakeholders, ensuring clarity and shared understanding.

Why You Should Apply

  • Pioneering AI Products: Contribute to a startup dedicated to cutting-edge generative AI and agentic frameworks.
  • Dynamic Environment: Grow your skills in a fast-paced setting that values innovation and experimentation.
  • Impactful Work: Help shape the next generation of AI-driven products that solve real-world challenges.
  • Collaborative Team: Join a diverse group of talented professionals who value transparency and mutual respect.
