Principal ML Engineer (Agentic AI) Vendor Data Team

We are on a lookout for a hands-on Principal ML Engineer (Agentic AI) to join the Vendor Data Team on our journey to always deliver amazing experiences to go beyond prompt engineering into autonomous orchestration: designing agents that generate their own prompts tools that empower AI with real-world actions and judge models that validate outputs. Your work wont sit in research notebooks itll ship.

The Agentic AI team is building the next generation of AI-native products intelligent systems that reason act and adapt. We combine the power of large language models (LLMs) autonomous agents and retrieval-augmented generation (RAG) to move beyond static prompts and chatbots into dynamic AI systems that solve real problems at scale.

We dont treat LLMs as tools to micromanage we treat them as collaborators. Our products are designed to build and evolve themselves leveraging AI to orchestrate workflows make decisions and continuously improve. If youre ready to stop building brittle bots and start building AI that builds AI this is your playground.

Key Responsibilities:

• Design and own end-to-end ML and data systems from ingestion and transformation to model integration and production deployment

• Architect and maintain scalable data pipelines for RAG embeddings and real-time/near-real-time data processing

• Build and operate production-grade ML services and APIs ensuring reliability scalability and performance

• Define standards for infrastructure deployment and system reliability including Infrastructure as Code containerization and orchestration

• Integrate ML systems with external APIs tools and operational platforms enabling real-world actions and automation

• Establish monitoring evaluation and observability frameworks across data models and systems while mentoring engineers and setting technical direction.

Qualifications :

• Strong experience designing and scaling production-grade ML systems and data platforms including large-scale deployments

• Deep expertise in data engineering and ML pipelines including feature/data pipelines RAG systems and embedding workflows

• Proven experience building and maintaining reliable data infrastructure with strong guarantees around data quality and freshness

• Strong engineering skills in Python and SQL with experience in Docker Kubernetes and cloud environments

• Experience with Infrastructure as Code (e.g. Terraform or similar) and building reproducible scalable systems

• Hands-on experience integrating ML systems with real-world APIs and services and operating them in production with monitoring and observability

Nice to have:

• Experience with LLMs agent architectures or orchestration frameworks (LangGraph AutoGen CrewAI etc.)

• Familiarity with synthetic data generation evaluation systems or AI feedback loops

• Experience with agent or ML observability tools such as Langfuse or LangSmith

• Experience with model serving routing or inference optimization

• Experience with open-source models (e.g. LLaMA Mistral Mixtral) or custom inference stacks

• Knowledge of system reliability failure handling and safety patterns in AI systems
