• Monitor, test, and continuously improve deployed agents based on customer feedback and analytics.
• Stay ahead of emerging trends in agent‑based AI and proactively bring innovative ideas into our products.

Your Profile

• Solid experience (8+ years) in software engineering with a focus on AI / ML systems.
• Hands‑on experience with LLMs, RAG pipelines, MCPs, context engineering, prompt engineering, or autonomous agent frameworks (e.g., LangChain / LangGraph, CrewAI, AutoGPT or similar).
• Strong programming skills in Python (preferred) and familiarity with cloud environments (AWS preferred).
• Good understanding of information retrieval, knowledge graphs, and / or planning & reasoning in AI.
• Familiarity with MLOps, experiment tracking, and model deployment practices.
• Experience working with unstructured text data and NLP tasks.
• Excellent problem‑solving skills, with a bias towards delivering results.
• Strong communication and teamwork abilities in a fast‑paced, collaborative environment.
• Nice to have: Experience with reinforcement learning or agent simulation environments.
• Background in human‑in‑the‑loop systems or AI safety / alignment.
• Contributions to open‑source agent frameworks or NLP libraries.
