If you thrive at the intersection of backend engineering and applied AI - and want to shape how automation drives smarter media outcomes - this role is for you.

Role Responsibilities:

• Design, build, and deploy scalable RESTful/async backend services using FastAPI and Python
• Architect and implement intelligent agent workflows (ReAct) using frameworks like LangChain, LangGraph, Crew AI, and LlamaIndex
• Create advanced conversational analytics and reporting interfaces integrated with large language models (LLMs)
• Deploy efficient retrieval-augmented generation (RAG) systems for actionable insights and automation
• Develop autonomous agents for media planning, campaign execution, performance monitoring, and continuous optimization
• Collaborate with product and analytics teams to define metrics, performance dashboards, and real-time analytics insights
• Implement and monitor ML pipelines to support campaign optimization
• Design, conduct, and interpret A/B tests with clear methodologies and statistical rigor
• Develop and implement predictive models to support decision-making processes and forecasting

Role Requirements:

• 2 - 4 years backend Python (FastAPI/Flask) or data engineering experience
• 1.5 - 2 years building and deploying agentic AI solutions (ReAct agents, RAG applications)
• Proficiency in async programming (asyncio), AWS, and CI/CD tools
• Hands-on experience building agentic AI systems using frameworks like LangChain, LangGraph, Crew AI, or LlamaIndex, with practical integration of LLMs (e.g., GPT, Claude) and vector databases such as Chroma or Pinecone
• Solid understanding of A/B testing, hypothesis testing, and predictive modeling
• Proactive attitude, strategic mindset, and ability to adapt quickly in a dynamic environment
