Senior Python Developer - Data & AI

At TechnologyOne, our mission is straightforward: to simplify life for our customers and empower them to thrive in a rapidly changing world. We are seeking a Senior Python Developer - Data & AI with deep experience in data‑driven and AI‑powered systems, particularly to work on agentic and LLM‑based architectures. This role focuses on designing, building, and deploying intelligent automation and AI agents that operate reliably in production environments.

You will work closely with product, data, and engineering leaders to deliver AI solutions that create tangible business impact. This is a hands‑on senior role with strong technical ownership and influence over standards, architecture, and best practices.

What you’ll be doing

AI & Agentic Development

• Design, build, and maintain agentic AI systems (multi‑step reasoning, tool use, orchestration, memory, and state management).
• Develop LLM‑powered workflows for automation, decision‑making, and user‑facing AI interactions.
• Implement prompt strategies, function/tool calling, and structured outputs for production‑grade AI systems.
• Evaluate and integrate AI frameworks and libraries (e.g., LangGraph‑style flows, custom orchestration).
• Work extensively with structured and unstructured data (JSON, text, tabular datasets).
• Build data processing and transformation logic to support AI workflows and analytics.
• Design efficient data access patterns for AI inference and evaluation.
• Ensure data quality, traceability, and observability across AI pipelines.

Technical Leadership

• Set coding standards and best practices for Python and AI development.
• Review code and mentor junior developers in AI and data engineering principles.
• Provide architectural guidance on AI systems and platform evolution.
• Contribute to technical documentation and internal knowledge sharing.

• Experience with APIs, asynchronous processing, and event‑driven systems.

AI & Data Stack

• Experience with LLMs.
• Familiarity with vector embeddings, retrieval, and similarity search.
• Experience working with AI evaluation, prompt iteration, and model behaviour tuning.
• Strong SQL and data analysis skills.
• Experience shipping production systems, not just experiments.
