SUMMARY
The Machine Learning Engineer provides hands-on expertise in designing, implementing, and scaling AI solutions, while collaborating with cross-functional teams to advance machine learning capabilities and support business innovation.

• Build and deploy AI agents powered by LLMs, including tool use, retrieval, memory, and orchestration workflows.

• Create robust eval frameworks to benchmark agent performance, safety, reliability, and cost efficiency.

• Integrate LLM agents with external tools, APIs, and MCP-based systems to enable action-taking and context-aware automation.

• Fine-tune and customize foundation models for domain-specific use cases using modern adaptation techniques.

• Monitor and improve production AI systems through experimentation, guardrails, and continuous performance optimization.

RESPONSIBILITIES

• Design, build, and optimize AI agents using LLMs, prompt engineering, retrieval, memory, tool use, and multi-step reasoning to solve real-world workflows and business problems.

• Develop and maintain evaluation pipelines (Evals) to measure agent quality, including accuracy, task completion, hallucination rate, tool-calling correctness, latency, cost, and safety.

• Integrate agents with tools and systems through APIs, MCP, databases, vector stores, and internal platforms so agents can reliably access context, perform actions, and operate in production environments.

• Fine-tune and adapt LLMs using techniques such as supervised fine-tuning, instruction tuning, LoRA/PEFT, and preference optimization to improve domain performance, reliability, and response quality.

• Deploy, monitor, and improve agent systems in production by implementing guardrails, observability, experimentation, feedback loops, and continuous model/prompt updates based on user and eval data.
