Senior AI/ML Scientist

Responsibilities:

• Design and build advanced ML models that integrate multi-dimensional data into insights and signals that drive critical business decisions.


• Design and build enterprise knowledge systems that integrate structured and unstructured data across multiple business platforms, enabling AI agents to retrieve, reason over, and operationalize trusted organizational knowledge.


• Partner with business stakeholders to identify, frame, and prioritize high‑value problems that can be addressed using Agentic AI, LLMs, and ML.


• Define and implement business-centric evaluation frameworks that measure coverage, relevance, trustworthiness, explainability, and user adoption in addition to technical model performance.


• 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.


• ML: Hands on experience with Gradient Boosting methods, familiar with preeminent hyper-parameter tuning and interpretability options.


• 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.


• 0Strong 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.
