Job Description

We are seeking a skilled AI Engineer to design, build, and deploy our core AI agent systems. You will be instrumental in taking our ideas from research prototypes to robust, production-ready applications that deliver real value to our users. 

The successful candidate should be innovative, team-oriented, and have a strong ability to learn.


Responsibilities


  • Design, develop, and evaluate robust AI agent systems and workflows using large language models [LLMs] and modern frameworks [e.g., LangChain, LangGraph].
  • Own the full LLM application lifecycle: from prototyping and prompt engineering to deployment, monitoring, and maintenance in production.
  • Architect and implement efficient Retrieval-Augmented Generation [RAG] systems utilizing vector databases.
  • Collaborate with cross-functional teams to define requirements and translate business needs into technical solutions.
  • Implement rigorous testing and evaluation frameworks to measure and improve the performance, reliability, and safety of our AI agents.
  • Optimize AI systems for scalability, latency, and cost-effectiveness.


Required Qualifications


  • Bachelor’s in Computer Science, Electrical Engineering, AI Engineering, or related field.
  • At least 5 years of experience in machine learning or software engineeering with a focus on AI
  • 1+ years of hands-on experience building applications with Large Language Models [LLMs]
  • Strong proficiency in Python and experience with modern LLM frameworks [e.g., LangChain, LangGraph, CrewAI]
  • Proven experience with the full ML Ops lifecycle: building, testing, deploying, and monitoring models in production [using tools like Docker, Kubernetes, MLflow, Weights & Biases].
  • Solid understanding of vector databases and their application in RAG systems.
  • Strong communication and collaboration skills.


Preferred Qualifications


  • Experience with low-level ML frameworks [PyTorch, TensorFlow] for fine-tuning LLMs.
  • Experience with speech recognition systems [e.g., Whisper] or computer vision models.
  • Contributions to open-source AI projects.
  • Experience with cloud platforms [AWS, GCP, Azure].
  • Background in designing evaluation frameworks for AI systems.
