Senior GenAI Engineer - Python

About the Client

We are seeking experienced Senior GenAI Engineer - Python and cloud-native application development. In this role, you will design, build, and optimize scalable backend systems that power AI-driven and intelligent automation solutions in the cloud.

What you will do

• Build LLM-powered features end to end. Design and implement agentic flows, retrieval, and tool calling using LangGraph - then ship them as FastAPI services with streaming, persistence and proper tests.
• Own answer quality. Build evaluation datasets, regression suites and LLM-as-judge checks so we know whether a prompt or model change made things better before it reaches users.
• Get the right context to the model. Turn user questions into effective queries against our search platform, orchestrate multi-step research loops, and shape the context the model reasons over. When an answer is wrong, work out whether retrieval, the query or the prompt is at fault - and fix the right one.
• Debug production. Instrument flows with tracing (Langfuse), investigate bad answers from real traces, and manage latency, token and cost budgets - including routing across model sizes and families behind an AI gateway.

What we are looking for

• Strong proficiency in Python for backend development (FastAPI, Flask, Django, or similar frameworks).
• Deep understanding of software architecture, design patterns, and API development.
• Solid experience with Azure cloud services, including containerization (Docker, Kubernetes), storage, and serverless technologies.
• Familiarity with CI/CD pipelines, infrastructure-as-code (Terraform, Bicep, ARM), and monitoring tools (App Insights, Prometheus, Grafana).
• General interest and experience with AI-driven applications, and automation
• Hands-on experience or strong understanding of AI-driven systems and intelligent automation workflows.
• Know how to work with LLM use API and know how their are tested, know what RAG is, LangGraph and other tools like that experience.
• Ability to apply prompt engineering and integrate machine learning or LLM APIs effectively.
• Proven track record in system build, scalability and performance optimization.
• Experience in code reviews, mentoring and setting engineering standards.
• Strong problem-solving skills, analytical thinking, and technical decision-making.
• Fluent in English, proactive communicator, and a collaborative team player.
• Open-minded, creative, and motivated to push boundaries in AI and automation.
