The role

You will drive the development of next-generation AI solutions by building agentic GenAI systems. You will also develop knowledge integration pipelines and set up evaluation and monitoring frameworks.

What you will do

• Design and build agentic GenAI systems using frameworks such as LangChain, AutoGen or Atomic Agents.
• Drive harness engineering practices across Data Science projects.
• Develop and maintain knowledge integration pipelines including RAG architectures, custom model fine-tuning, and vector search.
• Define evaluation strategies and build ground-truth datasets and automated test and monitoring setups.
• Collaborate with engineering, data, and product teams to integrate AI components into platforms and products.
• Act as a hands-on expert for GenAI and agentic software engineering topics and mentor peers.
• Experiment with new tools, models, and architectures to build prototypes.

Required qualifications

• A degree in computer science, data science, engineering, or a related field.
• Experience designing maintainable, agent-ready engineering environments.
• Strong coding skills in Python and experience with robust software engineering practices.
• Practical experience with RAG pipelines, vector databases, embeddings, or fine-tuning workflows.
• Strong understanding of common challenges in AI development.
• Experience deploying AI systems in a cloud environment and working with modern ML stacks.
• Familiarity with MLOps, prompt engineering, or LLM-based application design.
• Ability to explain complex AI topics in clear and actionable language to technical and non-technical stakeholders.
• High motivation, ownership mentality, and a strong drive to build impactful AI products.
