- Fine-tune and optimize large language models (e.g., GPT, BERT) using frameworks like Hugging Face Transformers.
- Conduct ongoing research to stay ahead of advancements in AI/ML, including LLMs, generative AI, and transformer-based architectures.
- Develop data pipelines for preprocessing, feature engineering, and model training.
- Test, validate, and monitor model performance in real-world scenarios; iterate for reliability and accuracy.
- Collaborate with cross-functional teams to embed AI into products, platforms, and services.
- Mentor junior engineers and contribute to technical leadership.

Automation & Agentic Systems

- Design, implement, and maintain automation workflows using tools such as:
- LangChain, LangGraph, LangSmith, LangFuse n8n, ElevenLabs, and CMS integrations.
- Engineer system-to-system integrations using APIs to enable intelligent process automation.
- Apply prompt and context engineering techniques to enhance the performance of conversational AI tools.
- Implement prompt management and QA processes for agents and assistants.
- Explore and deploy Microsoft Copilot Studio, PowerApps, and PowerAutomate solutions (preferred but not required).
- Continuously evaluate emerging AI and automation tools and assess their applicability in client use cases.
- Collaborate with clients and internal teams to scope, deliver, and maintain agentic and automation solutions aligned with business goals.

Qualifications

Required
