Key responsibilities

• Translate complex audit workflows into scalable, automated Python and SQL pipelines.
• Model and clean messy, multi‑client datasets.
• Design and integrate LLM reasoning with deterministic, auditable rule engines.
• Harden production systems by strengthening validation, refining orchestration logic, and improving performance.
• Package reusable AI “skills” for consistent deployment across engagements.
• Collaborate with audit, asset and engineering teams to ensure scalability, transparency and robustness.

Required profile

• 2–5 years of experience building production‑grade workflow, data or AI automation systems in multi‑client environments.
• Strong Python software engineering skills, including modular design, testing, packaging and async workflows.
• Experience designing scalable data pipelines using Python (Pandas or Polars) and SQL.
• Proven ability to work with messy, high‑variance datasets and implement automated data quality checks.
• Understanding of structured outputs, JSON schema enforcement and Pydantic validation.
• Experience integrating LLM‑based systems (RAG, tool calling, structured output pipelines).
• Familiarity with handling unstructured document data (PDF parsing, OCR, embeddings, classification).
• Exposure to CI/CD tooling such as Azure DevOps or GitHub.
