Job Description

Role: Senior Data Scientist - GenAI / RAG
Location: Houston, TX -preferred Or Dallas TX or Santa Clara CA (Onsite - 3 Days)

Type: Full-Time

We need candidates with real hands-on experience in Agentic AI and Traditional Data Science, not candidates who have only recently started exploring GenAI/LLMs. Continuous production implementation experience is preferred.

What the Hiring Team is Looking For

  • Traditional Data Scientists who have evolved into GenAI/Agentic AI solutions.

  • Candidates who can discuss end-to-end problem solving, feature engineering, predictive analytics, model selection, and solution design.

  • Hands-on experience designing and implementing RAG, LLM, and Agentic AI solutions.

  • Strong understanding of business use cases and ability to interact with customers and stakeholders.

  • Ability to explain architecture decisions, technical trade-offs, and implementation approaches.

Mandatory Skills

  • Strong Data Science background

  • Strong Machine Learning implementation experience

  • Hands-on LLM & RAG architecture and implementation

  • Experience with Agentic AI concepts and workflows

  • Strong client-facing / consulting and stakeholder communication skills

  • Exposure to Deep Learning concepts and implementations

  • Experience with cloud AI platforms such as AWS Bedrock, Azure OpenAI, or Vertex AI

We are looking for a Senior Data Scientist with a strong traditional ML/DS background and hands-on experience in GenAI (LLMs, RAGs, Agentic workflows). The candidate should not be purely academic or junior; we need someone with practical implementation experience and the ability to interact confidently with customers. Strong communication and product-facing exposure are equally important.
