About the role
- Conduct applied research in Generative AI, exploring emerging foundation models, architectures, and inference strategies to address enterprise AI use cases.
- Lead investigation and experimentation across areas such as: Agent‑based and multi‑step reasoning workflows, Retrieval‑augmented generation (RAG), Long‑context modeling and information synthesis, Prompting strategies and controllability of generative outputs.
- Design and execute rigorous experimental frameworks to evaluate model quality, robustness, latency, cost, and reliability using: Automated metrics, Human‑in‑the‑loop feedback, LLM‑as‑a‑judge and comparative evaluation methodologies.
- Create benchmarks and build reproducible pipelines to compare vendor models, open‑source alternatives, and internal approaches.
- Rapidly prototype research ideas using modern GenAI tooling such as: Vertex AI / Google Agent Development Kit, LangChain / LangGraph, RAG frameworks, Hugging Face ecosystems, OpenAI APIs.
- Translate research findings into deployable GenAI capabilities, working closely with engineering and MLOps teams to ensure scalability, observability, and responsible AI practices.
- Contribute to the enterprise GenAI roadmap by identifying gaps, risks, and opportunities informed by ongoing research and industry trends.
- Partner with stakeholders across Data Science, Technology, and Business teams to align research directions with real‑world operational challenges.
Requirements
- Masters and 5+ years of industry experience OR PhD and 3+ years of industry experience in machine learning or data science with 1+ years focused on GenAI.
- Strong proficiency in Python and modern AI/ML frameworks
- Demonstrated experience designing experiments, running evaluations, and drawing conclusions from empirical results.
- Hands-on experience with Generative AI frameworks and platforms, including Vertex AI, ADK, LangChain/LangGraph, RAG pipelines, Hugging Face, and OpenAI APIs.
- Deep understanding of: Agent workflows and tool‑augmented LLMs, Prompt engineering and model controllability, Retrieval‑augmented generation (RAG) design trade‑offs, Generative model evaluation and benchmarking techniques
- Experience collaborating with engineering and MLOps teams to transition prototypes into production systems.
- Strong written and verbal communication skills, including the ability to explain research findings, limitations, and trade‑offs to both technical and non‑technical audiences.
- Authorization to work in the United States without company sponsorship.
