Title: AI Application/GenAI Engineer(Only w2)
Location: Pleasanton, California (hybrid work)
Minimum 10+ years of Experience required.
Technical Overview:
We're seeking a highly skilled AI Application Engineer to lead the architecture and execution of advanced LLM-driven systems, including prompt engineering pipelines, evaluation frameworks, RAG workflows, and Lang Chain-based orchestration. In this role, you'll design and test prompts for style, tone, and accuracy, implement rigorous A/B and statistical evaluation frameworks, and deploy LLM-powered features into production.
Core Responsibilities:
• You’ll work cross-functionally with ML engineers, product managers, and backend teams to deliver scalable, prompt-driven solutions for enterprise applications.
• Responsibilities include building retrieval-augmented generation (RAG) pipeline, developing prompt evaluation systems using PromptEval or similar tools, and orchestrating LLM workflows with LangChain.
• This role demands a blend of deep prompt engineering expertise, practical Python development skills, and a strong analytical mindset to optimize prompt performance and user experience in real-world systems.
Required Expertise:
• 3 - 6 years in AI/ML, NLP or GenAI roles.
• Advanced knowledge of prompt engineering strategies and heuristics.
• Proficient with LangChain (or similar), Python and API development.
• Solid experience building RAG pipelines with vector DBs.
• Strong analytical mindset with an A/B testing and evaluation-driven approach.
