Quick Take -

As an AI Engineer, you’ll drive the end-to-end development of advanced GenAI applications, including agentic AI agents with autonomous workflows, function calling, and LLM model fine-tuning. This role is for an experienced engineer who excels at building robust, production-grade AI systems and pushing the boundaries of what GenAI can accomplish. This role can be done remotely from the United States. There is a strong preference for EST or CST location.

The Work -

• Fine-tune and deploy open-source general purpose LLMs and code-generation models (e.g. Llama 4, qwen2.5) using PEFT, LoRA, QLoRA, instruction tuning, RLHF, etc..
• Design GenAI applications with agentic capabilities—autonomous, goal-driven agents that can plan, reason, and execute multi-step workflows with minimal human input.
• Implement function calling in workflows, enabling models to invoke external tools, APIs, databases, and services to perform actions or access real-time data.
• Build agentic RAG pipelines, where LLMs coordinate data retrieval and reasoning dynamically via retrieval-augmented generation.
• Create and maintain scalable pipelines, including data ingestion, labeling, feature engineering, vector DB management, and MLOps frameworks (MLflow, Kubeflow).
• Containerize applications using Kubernetes and Docker.
• Optimize and monitor model performance, including latency, drift, bias, privacy, and security compliance.
• Collaborate cross-functionally, mediating between data, product, and engineering teams to translate requirements into agentic GenAI solutions.
• Stay current with research trends like agentic RL frameworks (e.g., ARTIST), multi-agent orchestration, MCP, and secure function calling.

The Must-Haves -

• B.S or M.S. in Computer Science, Data Science, ML/AI or equivalent.
• 3-5 years building and deploying AI/ML solutions with demonstrable production experience.
• Extensive experience fine-tuning LLMs and code models with advanced techniques (PEFT/LoRA/QLoRa/RLHF).
• Proven track record designing or delivering agentic GenAI applications—function calling, autonomous workflows, RAG pipelines.
• Proficient in Python, PyTorch/TensorFlow, Hugging Face, LangChain, LangGraph or similar frameworks.
• Experience in Document and Image Analysis and extracting insights from unstructured data, including text documents and images.
• Strong infrastructure skills: Docker, Kubernetes, CI/CD, MLOps tooling.
• Sharp analytical mindset for system optimization, error mitigation, and security best practices.
• Excellent problem-solving and ability to translate business needs into technical design.
