Qualifications

• 1-3+ years of experience in ML, Applied AI, DS, or software engineering.
• Experience with Large Language Models (LLMs) and AI-powered applications.
• Knowledge of LLM evaluation techniques, benchmarking, and LLM-as-a-Judge approaches.
• Understanding of AI agent behavior across multi-turn conversations and tool-calling workflows.
• Experience with prompt engineering, structured outputs, and prompt optimization.
• Familiarity with AI safety concepts including moderation, prompt injection prevention, jailbreak mitigation, and guardrails.
• Hands‑on experience with AWS cloud services, preferably Amazon Bedrock.
• Experience with Langfuse or similar observability and evaluation platforms for LLM applications.
• Strong programming skills in Python.
• Experience developing REST APIs using FastAPI or similar frameworks.
• Knowledge of software engineering best practices including unit testing, code reviews, and Git‑based development workflows.
• Advanced English communication skills (written and verbal).

Responsibilities

• Design and execute evaluation frameworks for AI agents, including test datasets, LLM-as-a-Judge methodologies, human reviews, and regression testing.
• Build, configure, and optimize AI guardrails and moderation systems for regulated domains such as financial services and credit products.
• Develop, test, and continuously improve prompts based on evaluation results and production trace analysis.
• Create and maintain MCP (Model Context Protocol) servers and tool integrations that enable AI agents to interact with internal data and services.
• Support fine-tuning and evaluation of language models using domain-specific datasets.
• Prototype and validate AI workflows using System One models such as Jev and Laya for classification, routing, and verification tasks.
• Monitor AI system quality, latency, performance, and costs through Langfuse and implement improvement initiatives.
• Collaborate with Engineering, Data Science, and Compliance teams to ensure AI solutions are reliable, secure, and compliant.
