Job Description

Responsibilities:

Solve Business Problems with AI

  • Partner with business stakeholders to identify, frame, and prioritize high‑value problems that can be addressed using Agentic AI, LLMs, and NLP.
  • Translate business needs into clear AI use cases, success metrics, and delivery plans.
  • Focus on business outcomes, not just model performance.

Design & Build Agentic AI Solutions

  • Architect and develop agentic AI systems that can reason, plan, and take actions across tools, workflows, and data sources.
  • Design multi‑agent and tool‑augmented LLM solutions to automate complex, multi‑step processes.
  • Ensure solutions are reliable, explainable, and governed for enterprise use.

Scalable & Responsible AI

  • Collaborate with engineering teams to deploy AI solutions with scalability, security, and performance in mind.
  • Implement evaluation, monitoring, and guardrails for LLM and agentic systems, including bias, drift, and failure modes.
  • Align solutions with enterprise risk management, compliance, and responsible AI standards.

Thought Leadership & Collaboration

  • Act as a trusted AI advisor, helping teams understand where Agentic AI and LLMs add value—and where they do not.
  • Contribute to AI best practices, reusable patterns, and strategic direction.
  • Mentor peers and teammates on applied AI and business‑driven problem solving.

Qualifications:

  • Agentic AI: Experience designing AI agents that reason, plan, and act across systems.

  • Large Language Models (LLMs): Hands‑on experience building enterprise LLM applications (e.g., RAG, tool use, orchestration, evaluation).

  • Natural Language Processing (NLP): Strong experience working with unstructured text and language‑driven workflows.

  • MS or PhD in Computer Science, Machine Learning, Data Science, or a related quantitative field.

  • 3 + years delivering AI/ML solutions in production environments.

  • 5 + years of hands‑on Python experience; experience with distributed data processing is a plus.

  • Strong ability to solve business problems using AI, not just build models.

  • Excellent communication skills, with the ability to explain complex concepts to both technical and non‑technical audiences.

  • Experience working in cross‑functional, enterprise environments.
