Publicis Sapient is looking for Python Developers to join our team of bright thinkers and enablers. You will use your problem-solving skills, craft, and creativity to design and develop infrastructure interfaces for complex business applications. You will build and orchestrate agentic, GenAI-powered workflows that transform how our clients operate – from data ingestion and enrichment to intelligent, LLM-driven automation. We are on a mission to transform the world, and you will be instrumental in shaping how we do it with your ideas, thoughts, and solutions.

Your Impact:

• Build and orchestrate agentic workflows using LangChain and LangGraph to power scalable, production-ready GenAI solutions.
• Develop reusable components for data ingestion, transformation, enrichment, and validation that accelerate delivery across projects.
• Ensure reliability, scalability, and traceability across agent workflows to support dependable, enterprise-grade AI applications.
• Implement performance monitoring with tools like LangSmith and apply tuning mechanisms to continuously improve agent accuracy and efficiency.
• Deploy and maintain Python-based GenAI services in production, leveraging Bitbucket, Git, and CI/CD tools for reliable releases.
• Architect secure API communication and access management, using JWT, OAuth, and RBAC, to safeguard sensitive client data.
• Apply NLP, LLM, and retrieval techniques, including vector stores and embeddings, to build context-aware, intelligent solutions for clients.

Your Skills & Experience:

• Strong Python fundamentals (OOP, data structures, error handling) with hands-on experience using Pandas, NumPy, PySpark, or Dask.
• Hands-on experience with LangChain, LangGraph, and Semantic Kernel, building agent orchestration, memory, and tool-use workflows.
• Proficiency in Python API frameworks (Flask/FastAPI), with experience using IDEs such as VSCode and PyCharm.
• Working knowledge of SQL/NoSQL databases, time-series data, and data modeling and schema design.
• Basic integration experience with TensorFlow or PyTorch, plus exposure to vector databases (e.g., FAISS, Chroma) and embedding-based retrieval.
• Proficiency with AWS Cloud Services and production deployment practices, including Bitbucket, Git, and CI/CD tools.
• Strong understanding of security & access management – JWT, OAuth, RBAC – and secure API communication.

Set Yourself Apart With:

• Prior work on GenAI, CoPilot, or RAG-based systems.
• Familiarity with marketing data models and real-time customer journeys.
• Exposure to NLP, LLMs, and retrieval frameworks beyond the core requirements above.

A Tip from the Hiring Manager:

“AI is evolving fast – join us to work hands-on with big clients, sharpen your skills, and stay future-ready.

Benefits of Working Here:
