Whether it’s expanding into new markets, streamlining operations, or driving digital transformation, we are committed to delivering impact that lasts.

Why NFQ?

🔹 Fairness – We treat our colleagues, clients, shareholders, and the environment with integrity and respect.
🔹 Entrepreneurship – We think like entrepreneurs, taking smart risks and turning ideas into real impact.
🔹 Excellence – We go beyond expectations to deliver results that truly make a difference.
We’re hiring a Python Developer to help us build intelligent, autonomous AI agents using Large Language Models (LLMs). You'll design and orchestrate complex agent behaviors using LangChain, while operating models across cloud, local, and edge environments. This role bridges cutting-edge LLM research with real-world deployment — from prompt engineering and fine-tuning to monitoring and observability.
You’ll work at the frontier of LLMs, agent architecture, and real-world deployment.

In this role, you will

    • Architect and implement modular LLM-driven agents that handle reasoning, planning, and tool usage.
    • Operate and integrate LLMs across environments — from cloud-hosted models (e.g., OpenAI, Anthropic, Azure, Bedrock) to local/edge deployments (e.g., llama.cpp, vLLM, Ollama).
    • Fine-tune and customize open-source LLMs using LoRA, QLoRA, PEFT, and other efficient tuning strategies.
    • Monitor, evaluate, and debug agent performance using LangSmith, OpenInference, Promptfoo, or custom observability tools.
    • Build retrieval-augmented generation (RAG) pipelines using vector stores like FAISS, Chroma or Pinecone.
    • Orchestrate queries
    • Collaborate with ML engineers, DevOps, and product teams to move prototypes into stable, production-ready systems.

What you will bring

    • Strong experience in Python 3.x, with a focus on modular, well-tested code.
    • Hands-on experience with LLMs in the cloud (OpenAI, Azure OpenAI, Claude, Bedrock, Hugging Face Inference Endpoints, etc.).
    • Experience operating LLMs locally/on-device (e.g., using Ollama, llama.cpp, vLLM, GGUF/GPTQ models).
    • Solid understanding of LLM agent frameworks (LangChain, CrewAI, AutoGPT) and prompt chaining.
    • Practical experience fine-tuning models (e.g., using Hugging Face Transformers, PEFT, LoRA/QLoRA).
    • Proficiency in using observability and evaluation tools (e.g., LangSmith, Promptfoo, TruLens) to trace, log, and improve performance.
    • Experience with embeddings, vector databases, and contextual memory systems.
      • Nice to Have:
    • Experience deploying LLMs to Kubernetes, serverless platforms, or edge devices (e.g., Jetson, mobile, Raspberry Pi).
    • Familiarity with quantization and optimization for low-latency inference.
    • Built or contributed to multi-agent systems or long-context memory chains.
    • Experience with model monitoring, alerting, and auto-evaluation pipelines in production.
